[0051] 图1-16示出媒体网络环境一个实现的配置及操作的一个示例。 [0051] FIG 1-16 shows an example of one implementation of a media network environment and configuration operations.

[0052] 在图I中,用户吉姆已建立了家庭媒体网络环境100,该网络环境包括两台设备:连接到电视110的PVR (个人视频录像机)105。 [0052] In Figure I, a user Jim has established a home media network environment 100, the network environment includes two devices: a TV 110 connected to the PVR (personal video recorder) 105. PVR 105是媒体网络顺从性设备,这意味着PVR 105根据为是集线器网络成员的设备定义的过程来操作。 PVR 105 is a media network compliant device, meaning that the device PVR 105 is defined according to the network hub member to operate the process. PVR 105包括存储内容拷贝(例如,作为存储在硬盘上的电子文件)的存储器,并且是服务器设备。 PVR 105 includes a copy of the stored content (e.g., as electronic files stored on a hard disk) memory, and a server device. 作为服务器设备,PVR 105是集线器网络的服务器,并可将内容提供给是集线器网络中成员的客户机设备。 As a server device, PVR 105 is the hub of a network server and can provide content to the network hub is a member of the client device. 作为服务器,PVR 105还定义本地环境(未示出)。 As a server, PVR 105 also defines a local environment (not shown). 在该示例中,PVR 105的本地环境定义为相对于PVR 105位置的物理区域(例如,由往返包定时或GPS信息确定的)。 In this example, the local environment of the PVR 105 is defined relative to the physical location of the region PVR 105 (e.g., round-trip packet timing or GPS information determined). PVR 105还是客户机设备。 PVR 105 or client device. 作为客户机设备,PVR 105可直接或通过连接的终端设备(诸如通过连接的电视110)再现内容。 As a client device, PVR 105 may be connected to the terminal device (such as by connecting the TV 110) or directly reproduce the content. 作为客户机和服务器设备,PVR 105作为集线器网络的服务器和集线器网络中的客户机是集线器网络的成员。 As a client and server equipment, PVR 105 server and network hub as the hub of a network of client is a member of the hub network. 在图I中,用“HN1”标记PVR105,来指示PVR 105是集线器网络I (HNl)的客户机设备。 In FIG. I, with "HN1" tag PVR105, PVR 105 to indicate that the network I is that the hub (HNL) client device. 还用“HN1*”标记PVR 105,来指示PVR 105是HNl中的服务器。 Also with "HN1 *" mark PVR 105, to indicate that the PVR 105 is the server HNl.

[0053] 电视110不是媒体网络顺从性设备,因此不能成为集线器网络的成员。 [0053] 110 is not a TV network media compliant device, and therefore can not become a member of the hub network. 然而,非顺从性设备可以是集线器网路的终端设备,接收用于呈现的数据(例如,显示电影的视频以及输出音频),无需存储内容的数据(除瞬变之外)。 However, the non-compliant network hub device may be a terminal device, receiving data for presentation (e.g., displaying video and outputting audio of a movie), without storing the content data (other than the transient). 相应地,PVR 105通过将用于呈现的内容数据输出到连接的电视110,来再现内容。 Accordingly, PVR 105 by the content data for presentation to the television output connection 110, to reproduce the content. [0054] 作为服务器设备,PVR 105最初建立集线器网路HNl。 [0054] As a server device, PVR 105 initially established a hub network HNl. PVR 105检查连接到PVR 105的其它顺从性设备。 PVR 105 checks other compliant devices connected to the PVR 105. 在将设备作为成员添加到集线器网络HNl之前,PVR 105认证设备,确定设备的身份,并授权认证的设备,确认设备是顺从性设备。 Before the device to the hub network HNl as a member, PVR 105 authentication device to determine the identity of the device, and authorized certified equipment, confirm that the device is compliant device. 如果PVR 105没有认证和授权设备,则PVR 105不将该设备添加到集线器网络HN1。 If the PVR 105 does not authenticate and authorize the device, the PVR 105 does not add that device to the hub network HN1. 在图I中,PVR105是唯一的顺从性设备。 In the FIG. I, PVR105 is the only compliant device. PVR 105将其自身作为服务器和客户机添加到集线器网络。 PVR 105 adds itself as a server and client to the hub network. 电视110不是顺从性设备,因此PVR 105不将电视110添加为成员。 TV 110 is not compliant device, so PVR 105 TV will not add to 110 members.

[0055] 在图2中,吉姆已购买了电影A和电影B,以及录制的电视节目C。 [0055] In Figure 2, Jim have purchased the movie A and movie B, and recorded TV programs C. 在该例中,吉姆购买了作为从连接到PVR 105的网络115下载的电子文件的电影A和B。 In this example, Jim purchased as an electronic document downloaded from a network 115 connected to the PVR 105 of the film A and B. 吉姆将节目C作为来自PVR 105的集成接收机接收的广播的电子文件来录制。 Jim C program will be broadcast as an electronic file of the integrated receiver received from the PVR 105 to record.

[0056] 如下所述,服从集线器网络操作的实例处于下面两种专用状态中的一种:离散或绑定。 [0056] The following Examples obey hub network operation is in one of two specific states: discrete or bound. 离散实例独立于任何集线器网络,并可通过任何顺从性设备(根据离散实例的许可证)来播放或呈现。 Examples of discrete independent of any hub network, and through any compliant device (according to the license of the discrete instance) to play or presentation. 然而,顺从性设备不能产生离散实例的可用拷贝。 However, the compliant device can not produce a usable copy of a discrete instance. 离散实例包括锁定内容数据和离散许可证。 Examples include discrete locked content data and discrete license. 离散实例的锁定内容数据称为锁定内容数据的“离散版本”。 Examples of discrete locked content data locked content data called "discrete version." 通过防止未经授权的访问(诸如通过加密),来锁定锁定内容数据。 By preventing unauthorized access (such as encryption), lock to lock content data. 绑定实例绑定到一个集线器网络。 Binding instance is bound to a hub network. 绑定实例是由在集线器网络服务器上和集线器网络的O个或多个客户机上存储的锁定内容数据及相应许可证所表示的一个逻辑实例。 Examples of the O binding is one or more clients on a network server and a hub network hub locking stored content data and a logical instance represented by the corresponding license. 服务器存储的锁定内容数据是集线器网络中内容数据拷贝的源,且是“源版本”。 Locked content data stored in the server is the hub network content data copy source, and the "source version." 源版本内容数据的拷贝存储在客户机上,且是“子拷贝版本”(虽然离散版本、源版本和/或任何子拷贝版本中的一些或全部数据可以是相同的)。 Store a copy of the source version content data on the client, and the "sub-copy version" (although the discrete version, the source version, and / or some or all of any sub-copy version of the data may be the same). 绑定实例仅可通过是集线器网络成员的兼容的顺从性设备来播放或呈现。 Binding instance only by a compliant device is compatible with the members of the network hub to play or presentation. 集线器网络的成员可产生绑定实例的内容数据的子拷贝。 Members of the hub network may generate content data of a copy of the bound instance.

[0057] 服务器设备可将离散实例的状态从离散变为绑定,禁止离散实例,并启动绑定实例。 [0057] The server device may be a discrete instance from discrete state becomes bound, to disable the discrete instance, bound instance and starts. 禁止的实例再现为不可用(例如,通过删除或加密实例的内容数据,或通过禁止实例的许可证)。 Examples of prohibited reproduction is unavailable (e.g., by deleting or content data encrypted instance, permit or prohibit by example). 服务器设备还可将绑定实例的状态从绑定变为离散,禁止绑定实例(包括任何相应的子拷贝),并启动离散实例。 The server device may further binding instance state changes from discrete binding prohibits binding instance (including any corresponding sub-copies) and start the discrete instance. 此外,集线器网络的服务器管理绑定实例的根职责(responsibility)。 In addition, network management hub server root duty bound instance (responsibility). 根职责包括发布和管理集线器网络中绑定实例内容数据的许可证。 Root responsibilities include license issuance and management of network hubs binding instance of content data. 相应地,服务器拥有根许可证,根许可证定义呈现绑定实例和管理集线器网络中绑定实例的内容数据和许可证的允许。 Accordingly, the license server has a root, root license allows custom rendering binding instance and network management hubs binding instance of content data and license. 当创建新的子拷贝时,还从根许可证创建子拷贝的许可证。 When you create a new sub-copy, create sub-copy license from the root license. 不服从集线器网络操作的内容实例是非顺从性实例。 Disobedience hub network operation is a non-compliant instance of content instances. 顺从性设备将根据可能与该实例相关联的任何识别拷贝控制信息来播放或拷贝非顺从性实例。 Compliant device will play or copy a non-compliant example of a control information may identify any copies of the associated instance.

[0058] 在图2-16中,字母标号指示内容实例的锁定内容数据的版本。 [0058] In FIG. 2-16, lettered examples indicating the content of a locking version of content data. 根据字母的变化来指示锁定内容数据的版本以及对应于锁定内容数据的实例的状态。 The letters indicated changes in the locking state and the version of the content data corresponding to the locked content data of instances. 下划线指示内容的离散版本。 Underline indicates the discrete version of the content. 例如,电影A的离散版本用“A”指示。 For example, A discrete version of the movie with "A" indication. 没有下划线的大写字母指示存储在服务器上的锁定内容数据的源版本。 Not underlined capital letters indicate source version of locked content data stored on the server. 例如,电影A的源版本用“A”指示。 For example, the version of the movie A source with the "A" indication. 小写字母指示锁定内容数据的子拷贝版本。 Lower case letters indicate the sub-copy version of locked content data. 例如,电影A的子拷贝版本由“a”指示。 For example, the sub-copy version of the movie A is indicated by "a". 这些版本还具有相应的许可证(图2-16中未示出):离散版本具有离散许可证,源版本具有根许可证,并且子拷贝版本具有子拷贝许可证。 The versions also have corresponding licenses (not shown in FIG. 2-16): a discrete version has a discrete license, a source version has a root license, and the sub-copy version has a sub-copy license.

[0059] 返回图2,吉姆通过将离散版本A和S存储在PVR 105中来经PVR 105将电影A和B引入集线器网络HN1。 [0059] Returning to Figure 2, Jim by discrete versions A and S to introduced hub network HN1 storage PVR 105 via the movies A and B in the PVR 105. PVR 105还存储节目C的离散版本£。 PVR 105 also stores a discrete version of the program C £. [0060] 在图3中,吉姆将离散实例绑定到集线器网络HNl。 [0060] In Figure 3, Jim discrete instance is bound to the hub network HNl. PVR 105将离散版本A、这和£的离散实例的状态变为绑定实例,并因此创建源版本A、B和C。 PVR 105 discrete versions A, and that the discrete state to Examples £ binding instance, and thus create a source versions A, B and C. PVR 105禁止或删除离散版本4、£和£。 PVR 105 to block or remove a discrete version 4, £ and £.

[0061] 在图4中,吉姆购买了包含顺从性设备的汽车120。 [0061] In Figure 4, Jim purchased a car 120 comprises a compliant device. 汽车120是服务器设备(例如包括存储器)和客户机设备(例如包括音频和视频系统)。 Car 120 is a server device (e.g., including storage) and a client device (e.g., including audio and video systems). 汽车120建立了第二集线器网络HN2,其中汽车120作为服务器(由“HN2*”指示)并作为成员客户机(由“HN2”指示)。 120 established a second automobile hub network HN2, where the car 120 as a server (the "HN2 *" indication) and as a member of the client (the "HN2" instructions). 汽车120基于距汽车120的相对距离(例如,汽车120包括确定往返包时间或提供定义汽车120位置的GPS信息的部件)来定义第二本地环境(未示出)。 Car 120 defines a second local environment to the relative distance (e.g., vehicle 120 includes a packet round-trip time, or determining the position 120 is defined to provide an automobile component GPS information) from the automobile 120 based on (not shown). 在图4中,汽车120和PVR105物理上彼此靠近,并因此汽车120的本地环境与PVR 105的本地环境基本同时扩张。 In Figure 4, the car 120 and PVR105 physically close to each other, and thus the car 120 and the PVR the local environment local environment 105 substantially simultaneously expanded.

[0062] 在图5中,吉姆连接了两个集线器网络HNl和HN2。 [0062] In Figure 5, Jim connects two hub network HNl and HN2. PVR 105和汽车120各包括无线网络能力。 PVR 105 and 120 each include a wireless automotive network capabilities. 吉姆使PVR 105和汽车120建立无线连接。 Jim so PVR 105 and cars 120 establish a wireless connection. 在PVR 105和汽车120检测到彼此时,它们的每一个都认证并授权另一个添加为成员设备。 When the PVR 105 and the car 120 detect each other, they are each other authentication and authorization device added as a member. 相应地,PVR 105将汽车120作为成员添加到集线器网络HNl (由添加到汽车120的“HN1 ”标号指示),并且汽车120将PRV105作为成员添加到集线器网络HN2 (由添加到PVR 105的“HN2”标号指示)。 Accordingly, PVR 105 adds car 120 as a member to the hub network HNL (from the addition to cars "HN1" label indicated 120), and the car 120 adds PRV105 as a member to the hub network HN2 (from the addition to the "HN2 PVR 105 of "label instructions).

[0063] 在图6中,吉姆将更多内容引入第二集线器网络HN2。 [0063] In Figure 6, Jim will be more into the second hub network HN2. 吉姆购买了存储在顺从性媒体产品(诸如顺从性光盘)上的电影X的顺从性实例。 Jim bought examples of compliance movie X stored on the compliant media products (such as compliance Disc). 顺从性媒体根据为可纳入(使绑定)集线器网络并从集线器网络释放的内容定义的过程来操作。 Compliant media operates according to the process to be incorporated (so bound) and released from the hub network hub network content definition. 具体地说,顺从性媒体允许根据实例状态的改变(例如在离散和绑定之间改变时)来禁止和激活存储在顺从性媒体上的实例。 In particular, compliant media allows (e.g., when changing between discrete and bound) and to prohibit instance on the compliant storage medium according to a change in the activation state of the instance. 此外,配置顺从性媒体,以使设备在没有授权的情况下不会创建存储在顺从性媒体上数据的完全逐位拷贝。 In addition, compliant media configuration, so that the device will not be created completely on a bit by bit copy of the data stored in the compliant media, without authorization. 由于存储在顺从性光盘上的实例是顺从性的,且还没绑定到任何集线器网络,因此该实例是离散实例。 Since instance stored on the compliant optical disc is compliant, and not bound to any hub network, the instance is a discrete instance. 吉姆将顺从性光盘插入到汽车120的服务器设备中,并使汽车120将电影X的离散实例绑定到集线器网络HN2。 Jim will be compliant CD into the car server device 120, and 120 cars will bind the discrete instance of the movie X to the hub network HN2. 汽车120创建电影X的绑定实例,并将锁定内容数据的源版本和根许可证作为绑定实例的一部分存储在汽车120的存储器中,并禁止顺从性光盘上的离散实例(例如,通过将数据存储到光盘)。 Automotive X 120 movie binding instance is created, and the lock source version of the content data and a root license as part of the binding instance storage memory car 120, and disable the discrete instance on the compliance of the CD-ROM (for example, by data stored in the disc). 在已禁止了顺从性光盘上的离散实例后,不能在另一设备上播放或呈现禁止实例的锁定内容数据的离散版本(如下所述,在另一实现中,当将离散实例绑定到集线器网络时,仍可通过离散实例绑定到的集线器网络中的成员设备来播放当时禁止的离散实例)。 After it has been disabled discrete instance on the compliant optical disc can not be played or presented discrete version (the locked content data as an example of prohibition on another device, in another implementation, the discrete instance when binding to the hub when the network is still to play discrete instances when prohibited) by members of the discrete device instance is bound to the hub network. 在图6中,电影X的源版本由添加到汽车120的“X”标号指示。 In FIG. 6, the source version of the movie X is added to the "X" Reference numeral 120 indicates car. 类似地,吉姆从网络115购买并下载了歌曲Y的顺从性实例,并让汽车将该实例绑定到集线器网络HN2。 Similarly, Jim purchased and downloaded from the network 115 compliance examples of songs Y, and let the car this instance is bound to the hub network HN2. 在图6中,歌曲Y的源版本由添加到汽车120的“Y”标号指示。 In FIG. 6, the source version of the song Y, "Y" indicated by the reference numeral 120 is added to the car.

[0064] 在图7中,吉姆通过集线器网络访问内容。 [0064] In Figure 7, Jim access web content through the hub. 吉姆决定通过PVR 105和连接的电视110观看电影X。 Jim decided to watch a movie X. by PVR 105 and 110 connected TV 作为集线器网络HN2的成员设备,PVR 105可访问绑定到集线器网络HN2的电影X。 As a member of the hub network equipment HN2's, PVR 105 can be bound to a hub network access HN2 movie X. PVR 105请求电影X的拷贝,并且作为集线器网络HN2服务器的汽车120将电影X的子拷贝版本提供给PVR 105。 PVR 105 requests copies of the movie X and the hub network HN2 as a server 120 of the sub-copy version of the movie X is supplied to the automobile PVR 105. PVR 105存储电影X的子拷贝版本(由添加到PVR 105的“X”标号指示),并通过连接的电视110呈现电影X。 The PVR 105 stores the sub-copy version of the movie X (from the addition to PVR "X" indicated numeral 105), and presenting a movie on television 110 is connected to X. 类似地,吉姆还决定通过PVR 105听歌曲Y,并因此PVR 105存储歌曲Y的子拷贝版本(由添加到PVR 105的标号“y”指示)。 Similarly, Jim also decides to listen to the song Y through the PVR 105, and thus the sub-copy version of the song Y PVR storage 105 (indicated by reference numeral 105 is added to the PVR "y" indication).

[0065] 吉姆随后决定通过汽车120观看电影A。 [0065] Jim then decided to watch a movie through the car 120 A. 作为集线器网络HNl服务器的PVR 105将电影A的子拷贝版本提供给汽车120。 As PVR 105 Hub server network HNl sub-copy version of the movie A to the car 120 is provided. 汽车120存储电影A的子拷贝版本(由添加到汽车120的标号“a”指示),并呈现电影A。 Car 120 stores the sub-copy version of the movie A (120 by the car added to the reference numeral "a" of instructions), and presents the movie A. [0066] 在图8中,吉姆购买了是顺从性设备的电视125。 [0066] In Figure 8, Jim purchased the television 125 compliant device. 电视125是客户机设备而非服务器设备。 TV client device 125 is not the server device. 相应地,电视125并不形成另一集线器网络。 Accordingly, the television 125 does not form another hub network.

[0067] 在图9中,吉姆将电视125连接到集线器网络HNl和HN2。 [0067] In Figure 9, Jim TV 125 is connected to the hub network HNl and HN2. 电视125支持有线连接和无线连接。 Television 125 supports both wired and wireless connections. 吉姆使PVR 105和电视125建立有线连接,并使汽车120和电视125建立无线连接。 Jim so PVR 105 and the television 125 to establish a wired connection, television and car 120 and 125 establish a wireless connection. 在PVR 105检测到电视125时,PVR 105认证并授权电视125添加为成员设备。 125 PVR 105 detects the television, PVR 105 authentication and authorization TV 125 added as a member device. 相应地,PVR 105将电视125作为成员添加到集线器网络HNl (由添加到电视125的“HN1”标号指示)。 Accordingly, PVR 105 adds the television 125 as a member to the hub network HNL (added to by the "HN1" Reference numeral 125 indicates the television). 类似地,汽车120认证、授权并将电视125作为成员添加到集线器网络HN2 (由添加到电视125的“HN2”标号指示)。 Similarly, automobile 120 authentication, authorization and television 125 to the hub network HN2 added (added to by the "HN2" Reference numeral 125 indicates a television) as a member.

[0068] 在图10中,吉姆通过电视125访问内容。 [0068] In Figure 10, Jim 125 accessed through the TV content. 吉姆决定通过电视125观看录制的节目C。 Jim decided to watch recorded television programs 125 C. 作为集线器网络HNl的成员设备,电视125可访问绑定到集线器网络HNl的节目C。 As a member of the hub network equipment HNl, the TV 125 can be accessed bound to a hub network HNl program C. 电视125请求PVR 105将节目C流到电视125。 The PVR 105 requests the TV 125 to flow television program C 125. PVR 105使用源版本C将节目C流到电视125上(由PVR 105和电视125之间标有“c”的虚线指示)。 PVR 105 using the source version of the program C 125 C flowing on the television (between the PVR 105 and the television 125 labeled "c" indicated by dashed lines). 电视125并不存储节目C的拷贝(除了在呈现流节目过程中瞬变的以外)。 Television program C 125 does not store a copy (except during the transients outside the rendering program stream). 类似地,吉姆决定通过电视125观看电影X,并因此汽车120使用源版本X将电影X流到电视上(由汽车120和电视125之间标有“x”的虚线指示)。 Similarly, Jim decides to watch the movie X through the television 125, and thus the car 120 using the source version X X movie on television flow (between the car 120 and the television 125 are marked with "x" indicated by dashed lines).

[0069] 在图11中,吉姆决定从集线器网络HN2释放或解除歌曲Y,以使歌曲Y便携。 [0069] In Figure 11, Jim decides to release or unlock the song Y from the hub network HN2, so that the song Y portable. 吉姆请求汽车120创建歌曲Y的离散实例。 Jim request car 120 creates a discrete instance of Y songs. 汽车120禁止歌曲Y的绑定实例,禁止歌曲Y的源版本以及任何子拷贝版本(由从PVR 105移除标号“y”和从汽车120移除标号“Y”来指示)。 Examples of binding Y prohibition vehicle 120 songs, song Y prohibited source version and any sub-copy version (removed numeral "y" and remove the reference numeral 120 "Y" from the bus indicated by the PVR 105). 汽车120创建歌曲Y的离散实例,并将离散版本(由添加到汽车120的标号“I”指示)存储在顺从性媒体(例如,顺从性硬盘或顺从性可记录盘)上。 Car 120 creates a discrete instance of the song Y, and discrete versions (by the automobile 120 is added to the reference numeral "I" instruction) is stored in the compliant media (e.g., a hard disk or a compliant recordable disc compliant) on.

[0070] 在图12中,吉姆从集线器网络HN2移除歌曲Y。 [0070] In Figure 12, Jim remove a song from the hub network HN2 Y. 吉姆将顺从性便携式存储设备130(例如可移动存储卡)连接到汽车120。 The Jim compliant portable storage device 130 (e.g. a removable memory card) to the car 120. 吉姆将歌曲Y的离散版本从汽车120移到便携式存储器130 (由从汽车120移除并添加到便携式存储器130的“Y标号指示),并将便携式存储器130连接到便携式音乐播放器135。便携式音乐播放器135是顺从性设备,且不是集线器网络的成员,但播放器135仍可播放来自离散版本I的歌曲Y,因为离散版本I的离散实例没绑定到集线器网络。 Jim discrete version of the song Y from the car 120 to move the portable memory 130 (portable memory "Y indicated by the reference numeral 120 is removed from and added to the car 130), and a portable memory 130 is connected to the portable music player 135. The portable music player 135 is a compliant device, and is not a member of the hub network, but the player can still play songs from Y 135 discrete version I, as a discrete version of the discrete instance I did not bind to the hub network.

[0071] 在图13中,吉姆决定从集线器网络HNl解除电影B,以将电影B给朋友萨利。 [0071] In Figure 13, Jim decides to lift the movie B from the hub network HNL, the movie B to a friend Sally. 吉姆请求汽车120创建电影的离散实例。 Jim request car 120 creates a discrete instance of the movie. PVR 105具有源版本B,并因此汽车120将该请求传给PVR 105。 PVR 105 has the source version B, and thus the car 120 passes the request to the PVR 105. PVR 105禁止电影B的绑定实例(由从PVR 105移除标号“B”指示)。 PVR 105 prohibits binding instance of the movie B (removed from the PVR 105 by a reference numeral "B" indication). PVR 105创建包括锁定内容数据的离散版本S的离散实例,并将离散版本S移到汽车120 (由添加到汽车120的标号“S”指示)。 PVR 105 creating a discrete version of locked content data S to a discrete instance and moves the discrete version S 120 cars (car by the reference numeral 120 is added to the "S" indication).

[0072] 在图14中,吉姆将车120开到他朋友萨利家。 [0072] In Figure 14, Jim opened the car 120 to his friend Sally home. 当吉姆驾车离开他的家时,汽车120离开媒体网络环境100,并进入萨利的媒体网络环境140。 When Jim drove away from his home, leaving the car 120 media network environment 100, and thus Rusa Li's media network environment 140. 在一个实现中,集线器网络的服务器设备监控集线器网络的成员设备,并确定成员设备何时已离开本地环境。 In one implementation, the members of the network device server hub hub device monitoring network and determine when a member device has left the local environment. 如上所述,在该示例中,由物理位置定义PVR 105和汽车120的本地环境。 As described above, in this example, is defined by the physical location of the local environment PVR 105 and the car 120. 当汽车120离开时,汽车120离开PVR 105的本地网络环境,并且汽车120将汽车120的本地环境远离PVR 105和电视125。 When the car 120 leaving the car 120 away from the PVR a local network environment 105, the car 120 and car 120 away from the PVR the local environment 105 and the television 125. 作为集线器网络HNl的服务器,PVR 105认识到汽车120已离开本地环境,因为汽车120不能向PVR 105报告其物理位置,或当汽车120向本地环境100边界之外的PVR 105报告物理位置时。 HNl hub network as a server, the PVR 105 to the car 120 has left the recognized local environment because the car 120 can not report its physical location to the PVR 105, the PVR 120 or when the car 100 to the outside of the boundaries of the local environment 105 reports a physical location. 类似地,作为集线器网络HN2的服务器,汽车120认识到PVR 105和电视125已“离开”汽车120的本地环境(即通过被留下)。 Similarly, as the server of the hub network HN2, the car 120 and the PVR 105 recognized television 125 is "away" local car environment 120 (i.e., by being left behind).

[0073] 当汽车120离开时,汽车120创建集线器网络HNl和HN2中的断开。 [0073] When the car 120 leaving the car 120 create a hub network HN2 HNl and is disconnected. 作为集线器网络HNl中的客户机,汽车120监控通过集线器网络HNl接收的每个子拷贝版本的截止周期。 As the hub of the client network HNl, automobile hub 120 by monitoring the received network HNl of each sub-copy version of the off period. 该周期是子拷贝版本的许可证中的机制,在存储子拷贝版本的客户机和管理绑定实例的服务器之间没有连接的情况下,用于控制子拷贝版本可使用多久。 This period is sub-copy version of the license mechanism between the server memory sub-copy version of the client and the binding instance managing without a connection, the sub-copy version for controlling how long may be used. 在该周期到期时(例如根据客户机中的安全时钟测量的),存储子拷贝版本的断开客户机禁止子拷贝版本。 When the period expires (e.g., according to the secure clock in the client measured) prohibits the sub-copy version, memory sub-copy version of the client has disconnected. 在该例中,周期是15天(由汽车120的标号“a_15”中的上标“_15”指示)。 In this embodiment, the period is 15 days (the superscript numerals car "a_15" 120 in the "_15" indication). 类似地,作为集线器网络HN2中的客户机,PVR 105监控通过集线器网络HN2接收的子拷贝版本的截止周期(由PVR 105的标号“X—15”中的上标“_15”指示)。 Similarly, the hub network HN2 as the client, monitoring PVR 105 received through the hub network HN2 off period of the sub-copy version (PVR 105 by the numeral of "X-15" in the superscript "_15" indication).

[0074] 在萨利的媒体网络环境140中,萨利具有游戏控制台145和连接的电视150。 [0074] In Sally's media network environment 140, Sally has a game console 145 and television 150 connected. 游戏控制台145是顺从性设备,并且既是服务器设备又是客户机设备。 145 game console is a compliant device, and is both a server device and a client device. 电视150不是顺从性设备,且用作终端设备,用于呈现来自游戏控制台145的内容。 TV 150 is not compliant device, and is used as a terminal device for presenting content from the game console 145. 游戏控制台145定义集线器网络HN3,并用作集线器网络HN3的服务器(由游戏控制台145上的标号“HN3*”指示)和集线器网络HN3中的客户机(由游戏控制台145上的标号“HN3”指示)。 Game console 145 defines a hub network HN3, and the hub network HN3 as a server (the game console by the reference numeral 145 "HN3 *" indication) and the hub network HN3 in the client (the game console by the reference numeral 145 "HN3 "instructions). 作为集线器网络的服务器,游戏控制台145定义本地环境(未示出)。 A hub network as the server, a game console 145 defines a local environment (not shown). 电影L和M以及歌曲N绑定到集线器网络HN3,并且游戏控制台145存储电影L和M的源版本(由游戏控制台145上的标号“L”和“M”指示)以及歌曲N的源版本(由游戏控制台145上的标号“N”指示)。 Movies L and M and song N bound to the hub network HN3, and the source game console 145 stores source versions of movies L and M (the game console by the reference numeral 145 "L" and "M" indication), and the song of N version (from the label on the game console 145 "N" instructions).

[0075] 在图15中,第二天,吉姆将汽车120连接到萨利的游戏控制台145,并将电影B的离散实例给了萨利。 [0075] In Figure 15, the next day, Jim the car 120 is connected to the game console 145 Sally, discrete instance and gave Sally B movie. 吉姆和萨利没让汽车120作为成员加入集线器网络HN3,或让游戏控制台145作为成员加入集线器网络HN2。 Jim and Sally did not let the car 120 to join as a member of a hub network HN3, or the game console 145 as a member to join hub network HN2. 为将电影B的离散实例给萨利,吉姆让汽车120将离散版本从汽车120移到游戏控制台(由从汽车120移除标号“S”来指示)。 For the discrete instance of the movie B to Sally, Jim let the car 120 from the discrete version of the car to move 120 game console (indicated by the label is removed from the car 120 "S"). 萨利让游戏控制台145将电影B的离散实例绑定到集线器网络HN3。 Sally let the game console 145 to bind the discrete instance of the movie B to the hub network HN3. 游戏控制台145禁止电影B的离散实例,并创建电影B的绑定实例,将源版本和根许可证存储在游戏控制台145的存储器中(由添加到游戏控制台145的标号“B”指示)。 B 145 game console ban the movie discrete instance and create the binding instance of B movies, game consoles will be in memory of the 145 (added to the game console from the source version and root license stored label 145 indicates "B" ).

[0076] 由于这是第二天,并且汽车120没有重新连接到集线器网络HNl或HN2,汽车120和PVR 105的时钟与子拷贝版本a和X的截止周期的结束仅差I天,因此在该周期到期之前剩下不到一天(由变为汽车120上的“a_14”和PVR 105上的“x_14”的标号指示)。 [0076] Since this is the next day, and the car 120 does not reconnect to the hub network HN2 or HNl, car end 120 of the PVR 105 and the off period of the clock and a sub-copy version X I shy of days, so the in less than one day (from the car becomes "x_14" indicated on the label "a_14" on the PVR 105 and 120) before the period expires. [0077] 在图16中,吉姆驾驶他的车120回家。 [0077] In Figure 16, Jim drove his car 120 to go home. 当汽车120离开时,汽车120从游戏控制台145断开。 When the car left the 120, the car 120 is disconnected from the game console 145. 当汽车120进入吉姆的媒体网络环境100时,汽车120连接到PVR 105和电视125。 When the car 120 enters Jim's media network environment 100, the car 120 to the PVR 105 and connected television 125. 汽车120已返回PVR 105的本地环境,并将汽车120的本地环境带回到PVR 105和电视125。 120 cars have returned to the local environment PVR 105, and 120 of the cars back to the local environment and TV PVR 105 125. 当汽车120重新连接到PVR 105时,作为集线器网络HNl的服务器的PVR 105重新设置存储在汽车120上的电影A的子拷贝版本a的截止周期(通过在汽车120上将标号“a_14”变为“a”指示)。 When the car 120 reconnects off period to 105 PVR, the PVR 105 as a network hub server HNl re-stored on the vehicle 120 is provided in the sub-copy version of the movie A is a (by reference numeral 120 on the car "a_14" becomes "a" instructions). 类似地,作为集线器网络HN2的服务器的汽车120重新设置存储在PVR 105上的电影X的子拷贝版本X的截止周期(通过在PVR 105上将标号“x_14”变为“x”来指示)。 Similarly, an automobile hub network HN2 server 120 re-off period is provided on the PVR 105 stores a sub-copy version of the movie X to X (indicated by reference numeral on the PVR 105 "x_14" becomes "x").

[0078] 在该例中,吉姆能够获取内容的实例,并将该实例绑定在他的家庭媒体网络环境的集线器网络中。 [0078] In this example, Jim can obtain an instance of content, and bind the instance of his home media network hub network environment. 吉姆能够呈现该内容,并在该媒体网络环境内产生拷贝。 Jim can render the content, and produce a copy of the media in the network environment. 当吉姆从媒体网络环境中释放内容实例时,移除了这些实例。 When Jim content instance is released from the media network environment, the removal of these instances. 以这种方式,当在媒体网络环境中绑定内容实例时,吉姆能够在整个媒体网络环境中使用他的内容,并随后在他希望该内容离开媒体网络环境时,移除该内容实例。 In this way, when binding media content instance in a network environment, Jim can use his entire media content in a network environment, and then when he wants to leave the content media network environment, remove the content example.

[0079] 媒体网络环境的配置和操作 [0079] network media environment, the configuration and operation

[0080] 图17-33示出了媒体网络环境中集线器网络的配置和操作。 [0080] FIG 17-33 illustrates the configuration and operation of hub networks in a media network environment is.

[0081] 网络配置 [0081] Network Configuration

[0082] 媒体网络环境包括一个或多个集线器网络,每个集线器网络都有各自的本地环境,其中的一些或全部可能重叠或共同扩张。 [0082] The media network environment includes one or more hub networks, each hub network has its own local environment, some or all of which may be overlapping or coextensive. 本地环境定义为有限区域,以使顺从性设备可以确定该设备是在本地环境内还是外。 The local environment is defined as a limited area, so that the compliant device may determine that the device is within or outside the local environment. 例如,可根据物理位置(例如,通过计算将包从服务器传播到客户机的往返时间,或使用来自集成到设备的GPS系统的地理定位数据)定义一个本地环境,而根据网络寻址信息(例如,使用IP地址和/或子网信息)或逻辑区域(例如,使用包所穿过的网关或路由器的数目来评估网络配置)定义另一个本地环境。 For example, according to the physical location (e.g., by calculating the packet propagation round trip time from the server to the client, or using a GPS system from the integrated device to the geolocation data) defines a local environment, according to the network addressing information (e.g. , IP address and / or subnet information) or logical area (e.g., the number of gateways or routers traversed by a packet used to assess the network configuration) define another local environment. 根据相对于集线器网络的服务器来定义本地环境(例如,以服务器为中心半径为100米的圆)。 Phase to define the local environment (e.g., server-centric circle radius of 100 meters) server for the hub network. FIG. 当服务器状态改变时(例如服务器移动时),本地环境也可改变。 When the server status changes (e.g., the server moves), the local environment may also change. 如下所述,当顺从性设备处于集线器网络的本地环境时,可加入该集线器网络中,而当该设备离开本地环境时,从该集线器网络中断开该设备(虽然该设备可以一直是成员)。 As described below, when the device is in the local environment of the compliant hub network may be added to the hub network, and when the device leaves the local environment, the device is disconnected from the hub network (though the device may always be a member) . 如果设备虽然在离开本地环境之后仍能保持网络连接(例如无线连接),但当该设备在本地环境以外时,仍被视为断开的。 If the device while still maintained after leaving the local environment a network connection (e.g., wireless connection), but the device is outside the local environment, still considered open.

[0083] 媒体网络环境包括一个或多个设备。 [0083] The media network environment includes one or more devices. 在一个实现中,设备是整装的软件应用、硬件部件或上述组合。 In one implementation, the device is self-contained software application, hardware component, or a combination thereof. 例如,一个计算机系统可包括多个硬件和/或软件设备。 For example, a computer system may comprise a plurality of hardware and / or software devices. 媒体网络环境中的各设备是媒体网络顺从性设备(顺从性设备),或不是媒体网络顺从性设备(非顺从性设备)。 Each media device is a media network environment a network compliant device (a compliant device) or is not a media network compliant device (a non-compliant device). 顺从性设备根据为媒体网络环境和集线器网络定义的规则操作。 Compliant device operating according to the rules for the media network environment and a hub network is defined. 顺从性设备可以是集线器网络的成员,诸如服务器或客户机设备。 Compliance device can be a member of a hub network, such as a server or a client device. 非顺从性设备(诸如终端设备)不能是媒体网络环境中的集线器网络的成员。 Non-compliant devices (such as a terminal device) can not be a member of a hub network in a media network environment. 非顺从性设备可与集线器网络相互作用,诸如从集线器网络成员设备接收作为输出数据的内容,如下所述。 Non-compliant device can interact with a hub network, such as that received from a hub network member device, as the contents of the output data, as described below. 然而,非顺从性设备不能解密和再现内容的顺从性拷贝。 However, the non-compliant device can not decrypt and reproduce the content compliant copy.

[0084] 集线器网络包括一个或多个成员设备。 [0084] The network hub comprises one or more member devices. 集线器网络中的各成员设备是服务器、客户机或两者。 Members device hub network server, client, or both. 例如,成员设备可包括同一物理系统中的服务器和客户机功能性。 For example, members of the same physical device may comprise a server system and client functionality. 每个集线器网络都有一个服务器。 Each hub has a network server. 每个客户机都直接或通过网络连接连接到服务器。 Each client directly or via a network connection to the server. 以这种方式,集线器网络服从以服务器为中心的集中星型或星型拓扑。 In this way, network hubs obey hub and spoke or star topology and server-centric. 多个服务器设备可以是同一集线器网络中的成员,其中一个服务器设备用作集线器网络的服务器,并且附加的服务器设备用作集线器网络服务器的客户机(通过它们的客户机功能性)。 A plurality of server devices can be members in the same hub network, wherein the server device as a network hub server, and the server device is used as an additional hub client network server (through their client functionality).

[0085] 集线器网络的服务器是集线器网络的焦点,并管理集线器网络控制的许多方面。 [0085] The network hub server hub is the focus of the network, and manage many aspects of the hub network control. 服务器管理内容绑定实例的根职责,并将内容提供给集线器网络中的客户机成员。 Bind root server management responsibilities content instance, and content to the client member hub network. 服务器存储锁定内容数据的源版本和绑定实例的相应根许可证。 Corresponding root license server stores locked content data source versions and binding instance. 服务器将绑定实例的锁定内容数据的子拷贝版本提供给客户机,或将锁定内容数据源版本的数据流到客户机。 The content server locks data binding instance sub-copy version to the client, or the data source version of locked content data stream to a client. 服务器管理实例、处理许可、管理网络成员资格、监控设备与集线器网络的连接和断开,并执行时间管理。 Examples of server management, license processing, network management membership, monitoring equipment and network hub connection and disconnection, and execution time management. 服务器定义集线器网络的本地环境。 Network hub server definition of the local environment. 如下所述,服务器通过将实例状态从离散(集线器网络外部)变为绑定(集线器网络内部)来将内容实例绑定到集线器网络,并且服务器通过将实例状态从绑定变为离散来从集线器网络中释放实例。 As described below, by the server instance from the discrete state (external network hub) becomes bound (internal hub network) to bind content instance to the hub network, and the server by the discrete instance state changes from the binding from the hub the network released instance.

[0086] 集线器网络中的客户机播放或呈现来自内容实例的内容数据(例如,通过解密和再现存储在实例锁定数据版本中的内容数据)。 [0086] hub network play or present the client instance of content from the content data (e.g., locked content data versions in Example decrypted and reproduced by the storage). 客户机设备从服务器接收锁定内容数据的子拷贝版本和绑定实例的子拷贝许可证,或从服务器接收流数据。 The client device receives the content data from a server to lock the sub-copy version and sub-copy license binding instance, or receive data from the streaming server. 客户机设备包括存储子拷贝版本(存储客户机设备)的存储器,或不存储子拷贝版本(非存储客户机设备)。 The client device includes a storage sub-copy versions (a storage client device) memory or storage sub-copy version (non-storage client device). 客户机设备直接通过集成部件或通过连接的终端设备来呈现内容数据。 The client device presents content data directly connected to the terminal device or by integrating member. 在另一实现中,客户机设备还可将内容数据从子拷贝版本流到是同一集线器网络成员的另一客户机设备。 In another implementation, the client device may also flow from the content data of the same sub-copy version to another member of the hub network client device.

[0087] 终端设备用于呈现内容,并且不是集线器网络的成员。 [0087] The terminal device for presenting content, and is not a member of the hub network. 终端设备连接到成员设备,并接收用于呈现的数据,诸如输出视频和音频数据。 A terminal connected to a member device and receives data for presentation, such as output video and audio data. 终端设备也可提供除媒体网络环境之外的服务的其它功能。 The terminal device may provide other functions in addition to serving media network environment.

[0088] 当媒体网络环境包括两个或两个以上集线器网络时,集线器网络中的一些或全部可能重叠。 [0088] When a media network environment includes two or more hub networks, the network hub may overlap some or all. 当其中两个集线器网络都包括相同设备时,这两个集线器网络重叠。 Wherein when the two hub networks include the same device, the two hub networks overlap. 属于两个集线器网络的设备跨越这两个集线器网络,并且是跨越设备。 Two devices belonging to two hub networks spans the hub networks and is a spanning device. 跨越设备存储(或能存储)绑定到每个集线器网络的实例的内容数据。 Spanning device stores (or can store) content data bound to the hub network each instance. 相应地,跨越设备可呈现绑定到多个各自集线器网络的内容(绑定实例仅绑定到一个集线器网络)。 Accordingly, the device across a plurality of content may be presented bound to each network hub (bound instance is bound to only one hub network). 然而,在一个实现中,跨越设备仅在同一本地环境中跨越多个集线器网络。 However, in one implementation, only spans across multiple devices in the same local network hub environment. 在此情况下,如果设备成为不同本地环境中集线器网络的成员,则该设备将仅呈现来自该设备最近连接到的集线器网络的内容。 In this case, if the devices become members of different local environment of the hub network, the device will show only the most recent content from the device connected to the hub network. 在另一实现中,跨越设备可跨越不同本地环境中的集线器网络,并播放来自任何跨越设备的集线器网络的内容(服从许可证要求,诸如如下所述的刷新)。 In another implementation, the device may span across different local environment of the hub network, hub network and play content from any of the spanning device (subject to license requirements, such as a refresh).

[0089] 重叠的集线器网络提供了管理内容的使用和拷贝的灵活环境。 [0089] The overlapping hub networks provide a flexible environment for use and copying of content management. 每个服务器管理服务器的集线器网络中的设备和内容,并且每个客户机遵循集线器网络的规则而操作。 Each hub network server management server devices and content, and each client to follow the rules and operation of the network hub. 结果,用户可以便利的方式通过媒体网络环境呈现、移动和拷贝内容数据,同时控制内容数据的呈现、拷贝和移动,以反映(例如由内容所有者)为许可授权设置的许可准则。 As a result, the user can convenient way through the media network environment presents, move and copy content data while controlling the presentation of the content data, copying and moving to reflect (for example, by the content owner) to permit the licensing criteria set. 此外,各集线器网络的管理以集线器网络的服务器为基础。 In addition, the management of the network hub to hub server-based network.

[0094] 存储客户机设备1720和非存储客户机设备1725是客户机设备。 [0094] The storage client device 1720 and the non-storage client device 1725 are client devices. 作为客户机设备,存储客户机设备1720和非存储客户机设备1725通过集成的媒体部件(例如音频和视频输出)来呈现内容数据。 As client devices, the storage client device 1720 and the non-storage client device 1725 present content data through integrated media components (e.g. audio and video outputs). 如上所述,服务器/客户机设备1705也是客户机设备,但通过连接的终端设备1710来呈现内容数据。 As described above, the server / client device 1705 is also a client device but presents content data to the terminal device 1710 is connected. 存储客户机设备1720包括存储内容数据的子拷贝版本的存储器。 Storage client device 1720 includes sub-copy version of the content data stored in memory. 存储客户机1720呈现存储在存储客户机1720中的子拷贝版本的内容数据,或从服务器(例如,服务器/客户机设备1705)作为流数据接收的内容数据。 Storage client 1720 presents content data stored in the sub-copy version stored in the client 1720, or from a server (e.g., server / client device 1705) as the received content stream data. 非存储客户机1725不存储呈现的内容数据的子拷贝版本。 Sub-copy version of the non-storage client 1725 does not store the contents of the data presented. 非存储客户机1725呈现从服务器(例如服务器设备1715)作为流数据接收的内容数据。 Rendered non-storage client 1725 from a server (e.g., server device 1715) as the received content stream data. 在另一实现中,所有客户机设备都是非存储客户机设备。 In another implementation, the client devices are all non-storage client device. 在此情况下,如果设备具有绑定数据内容的存储器,则该设备是服务器或服务器/客户机设备。 In this case, if a memory device having a data content of binding, then the device is a server or server / client device.

[0095] 服务器/客户机设备1705是集线器网络HNl的服务器,由服务器/客户机1705上的“HN1*”标号指示。 [0095] The server / client device 1705 is the server of the hub network HNl, by the "HN1 *" label instructions on the server / client 1705. 服务器/客户机设备1705和存储客户机设备1720是集线器网络HNl中的客户机,由“HN1”标号指示。 The server / client device 1705 and storage device 1720 is a client in the hub network HNl clients, the "HN1" numerals. 终端设备1710连接到服务器/客户机设备1705,用于呈现来自服务器/客户机设备1705的内容数据。 The terminal device 1710 connected to the server / client device 1705 for presenting content data from the server / client device 1705. 终端设备1710不是集线器网络HNl的成员。 Terminal device 1710 is not a member of the hub network HNl. 服务器设备1715是集线器网络HN2的服务器,由服务器设备1715上的“HN2*”标号指示。 The server device 1715 is the server of the hub network HN2, "HN2 *" label on the server device 1715 indicated by the. 服务器/客户机设备1705、存储客户机设备1720和非存储客户机设备1725是集线器网络HN2中的客户机,由“HN2”标号指示。 The server / client device 1705, the storage client device 1720 and the non-storage client device 1725 is the hub network HN2 the client, the "HN2" numerals. 非存储客户机设备1725不存储内容数据的子拷贝版本,而是接收来自服务器设备1715的流数据,由从服务器设备1715到非存储客户机设备1725的虚线指示。 Sub-copy version stored in the non-client machine device 1725 does not store content data, but receives streaming data from the server device 1715, from the 1715 to the dashed line indicates the non-storage client device 1725 of the server device.

[0096] 两个集线器网络HNl和HN2是重叠的,这定义了重叠或覆盖的集中星型结构。 [0096] HNl two network hubs and HN2 are overlapping, which defines the centralized star structure or overlapping coverage. 集线器网络HNl包括服务器/客户机设备1705和存储客户机设备1720。 HNl hub network including a server / client device 1705 and the storage client device 1720. 集线器网络HN2包括服务器/客户机设备1705、服务器设备1715、存储客户机设备1720和非存储客户机设备1725。 Hub network HN2 includes the server / client device 1705, the server device 1715, the storage client device 1720 and the non-storage client device 1725. 服务器/客户机设备1705和存储客户机设备1720是集线器网络HNl和HN2的成员,并因此是跨越设备。 Server / client device 1705 and the storage client device 1720 and is a member of the hub network HNl HN2, and therefore is across the device.

[0097] 存储设备1730是顺从性媒体设备,且连接的播放器设备1735是非顺从性设备。 [0097] The storage device 1730 is a compliant media device and the player device 1735 are non-compliant device is connected. 存储设备1730和播放器设备1735不是集线器网络HNl和HN2的成员。 Storage devices 1730 and 1735 is not a player device hub network HNl and members of HN2. 存储设备1730是包括顺从性媒体(诸如顺从性闪存卡)的便携式存储设备。 Storage device 1730 is a compliant media (such as a compliant flash memory card) of the portable storage device. 播放器设备1735是便携式媒体播放器设备,诸如MP3播放器。 Player Unit 1735 is a portable media player device, such as an MP3 player. 在其它环境中,不是便携式的非顺从性设备可连接到一个或多个顺从性设备。 In other environments, non-compliant are not portable devices can be connected to one or more compliant devices.

[0098] 存储设备1730连接到服务器设备1715(例如插入到端口),并因此可与服务器设备1715交换数据。 [0098] storage device 1730 connected to the server device 1715 (e.g., inserted into a port), and thus can exchange data with the server apparatus 1715. 相应地,存储设备1730和服务器设备1715可交换离散实例。 Accordingly, the storage device 1730 and the server device 1715 interchangeably discrete instance. 存储设备1730连接到播放器设备1735,且播放器设备1735可呈现存储在存储设备1730中内容数据的非顺从性拷贝。 A storage device 1730 connected to the player device 1735 and the player device 1735 can present non-compliant copies of content data stored in the storage device 1730. 由于播放器设备1735是非顺从性设备,因此播放器设备1735不能播放或呈现存储在存储设备1730上的顺从性内容数据。 Because the player device 1735 are non-compliant device, so the player device 1735 can not play or present compliant content data stored on the storage device 1730. 存储设备1730不能从存储在存储设备1730上的离散实例产生可用的拷贝。 Storage device 1730 can not produce usable copies from discrete instances stored on the storage device 1730.

[0099] 集线器网络成员资格 [0099] hub network Membership

[0100] 服务器管理集线器网络中设备的成员资格。 [0100] Membership server management hub in a network device. 服务器将客户机作为集线器网络的成员添加和移除。 The server will add and remove clients as a member of the hub network. 服务器只将许可证授予成员设备。 The license granted to a member server only device. 一旦用户批准,服务器就在认证客户机设备是顺从性设备之后将客户机设备添加为成员。 Once the user approves, the authentication server on the client device is compliant device after adding a client device as a member. 如果服务器也是客户机设备,则最初服务器自动将其自身添加为客户机。 If the server is also a client device, the first server to automatically add itself to the client. 在一个实现中,服务器也视为成员。 In one implementation, the server also as members. 在另一实现中,只有客户机是成员。 In another implementation, only the client is a member. 一旦添加为成员,设备就是成员,直到服务器将该设备作为成员移除为止。 Once added as a member, the device is a member, as a member until the server to remove the device so far. 在用户请求时,或当满足撤消成员资格的条件时,服务器将客户机设备作为成员移除。 When a user requests, or revoked when the conditions for membership are met, the server will remove the client device as a member.

[0101] 图18示出了将设备作为成员设备添加到集线器网络的一个实现的流程图1800,诸如将存储客户机1720添加到图17中的集线器网络HN1。 [0101] FIG. 18 shows a flowchart of one implementation of the device as a member of the 1800 devices to the hub network, such as adding storage client 1720 to the hub network HN1 in Figure 17. 最初,客户机设备连接到集线器网络(块1805)。 Initially, client device connected to a hub network (block 1805). 客户机可通过有线或无线连接直接连接到服务器,或诸如可通过中介网络设备来间接连接到服务器。 The client can be connected directly to the server via a wired connection or wireless, or may be indirectly connected, such as through intervening network devices to the server. 服务器不会将未连接的设备添加为成员(即使参见以下所述使用中间设备添加未连接设备的备选实现)。 The server does not unconnected device added as a member (see below, even if the intermediate device to add an alternative implementation of the unconnected device).

[0102] 服务器检测连接的客户机设备(块1810)。 [0102] The server detects the client device is connected (block 1810). 顺从性设备将消息或连接通知发送到集线器网络上的设备,该消息或连接通知指示该设备现在连接到集线器网络。 Compliant device sends a message or connection notification to devices on the hub network, the message or connection notification indicating that the device is now connected to the hub network. 在另一实现中,服务器为新客户机周期性地轮询连接的设备。 In another implementation, the new client to the server periodically polls connected devices.

[0103] 服务器认证检测的客户机设备(块1815)。 [0103] authentication server detects a client device (block 1815). 服务器发送来自客户机设备的信息的顺从性确认请求,以确定该客户机设备是否是顺从性设备。 Compliant server sends confirmation information from the client device a request to determine whether the client device is a compliant device. 例如,服务器发送为顺从性设备加密的确认请求。 For example, for the server sends a confirmation request encrypted compliant device. 如果客户机设备没有正确响应,或服务器确定该客户机设备不是顺从性设备,则认证失败,并且该服务器不会将客户机设备作为成员添加到集线器网络。 If the client device does not respond correctly, or the server determines that the client device is not compliant device, the authentication fails, and the server does not add the client device as a member to the hub network.

[0104] 在确认客户机设备是顺从性设备之后,服务器发送来自客户机设备标识该客户机设备的信息的标识请求。 [0104] After confirming that the client device is a compliant device, the server sends an identification request message from the client device identifying the client device. 服务器具有认证客户机设备所需的最小标识信息集,诸如MAC地址(媒体访问控制地址)。 The minimum set of identifying information required to authenticate a server with a client device, such as a MAC address (Media Access Control address). 在一个实现中,顺从性设备具有集线器网络的安全且唯一的设备标识符。 In one implementation, a compliant device has a secure and unique network hub device identifier. 如果客户机设备不响应或不提供适当的信息,则认证失败,并且服务器不会将客户机设备作为成员添加到集线器网络。 If the client device does not respond or does not provide the appropriate information, the authentication fails, and the server will not add the client device as a member to the hub network. 如果服务器认证客户机设备,则服务器检查成员设备列表,以查看认证的客户机设备是否已在成员设备列表中。 If the server authentication client device, the server checks the device list member to view authenticated client device is already in the list of member devices. 如果是,则服务器不需要将客户机设备添加为成员,并通知用户该设备已重新连接。 If so, the server does not need to be added as a member client device, and notifies the user that the device is reconnected. 服务器和客户机根据以下参考图21(讨论了成员设备的重新连接)所述的进行。 The server and client below with reference to FIG. 21 (discussing reconnection of a member device) according performed. 在一个实现中,服务器将认证的客户机设备添加到服务器集线器网络的认证连接设备列表中。 In one implementation, the server will authenticate client devices are added to the list of devices connected to the authentication server hub network.

[0105] 在成功认证客户机设备之后,服务器从用户接收添加客户机设备的添加请求(块1820)。 [0105] After successful authentication client device, the server receives the add request to add the client device (block 1820) from the user. 服务器等待继续添加客户机设备,直到服务器从用户接收到添加特定客户机设备的肯定请求为止。 Continue to add the server waits for a client device, until the server is received from the user to add up requesting a specific client device. 在另一实现中,在检测到设备时,服务器请求来自用户的添加认证设备的批准或确认,而不是等待来自用户的请求。 In another implementation, when the device is detected, the server requests approval or confirmation from the user to add the authentication device, instead of waiting for a request from the user. 在另一实现中,服务器等待认证客户机设备,直到接收到添加客户机的请求或批准后为止。 In another implementation, the client device authentication server waits until it receives a request or approval after adding clients so far.

[0106] 在接收到添加客户机设备的请求之后,服务器授权客户机设备(块1825)。 [0106] After receiving the request to add the client device, the server authorizes the client device (block 1825). 在一个实现中,客户机必须在要添加的集线器网络的本地环境中。 In one implementation, the client must be in the local environment of the hub network to be added in. 服务器发送来自客户机对信息的本地环境确认请求,以确定该客户机设备是否在集线器网络的本地环境中。 The server sends a local environment confirmation request for information from the client to determine if the client device is in the local environment of the hub network. 在一个实现中,服务器发送测试消息,并等待来自客户机的响应(例如强制回应客户机)。 In one implementation, the server sends a test message and waits for a response from the client (e.g., pings the client). 基于发送测试消息和接收响应之间的时间量,服务器确定客户机是否在本地环境中(例如,低于阈值的往返时间指示客户机在本地环境内)。 Based on the amount of time between sending the test message and receiving a response, the server determines whether the client in the local environment (e.g., round trip time below a threshold indicates a client is within the local environment). 在另一实现中,服务器将本地环境信息发送到客户机设备,且客户机设备确定该客户机设备是否在本地环境中。 In another implementation, the server sends local environment information to the client device and the client device determines that the client device is in the local environment. 如果服务器没确定客户机设备在集线器网络的本地环境中,则认证失败,并且服务器不会将客户机设备作为成员添加到集线器网络。 If the server did not identify the client device in the local environment of the hub network, the authentication fails, and the server will not add the client device as a member to the hub network.

[0107] 在一个实现中,在授权客户机设备之前,服务器还确认客户机设备不在服务器的撤消列表上。 [0107] In one implementation, before granting a client device, the server also confirmed the revocation list of the client device is not in the server. 如下所述,撤销列表指示已撤消授权的设备。 As described below, the revocation list indicates devices authorized revoked. 在一个实现中,服务器将授权的客户机设备添加到授权设备列表中。 In one implementation, the server authorized the client device is added to the list of authorized devices.

[0108] 在成功授权客户机设备之后,服务器确认集线器网络中成员设备的数量低于成员设备极限(块1830)。 [0108] After the successful authorization of client devices, servers confirm the number of members of the network hub device is lower than the limit member devices (block 1830). 服务器存储设备极限,该设备极限指示服务器将作为成员添加到集线器网络的成员设备的最大数量(诸如20)。 Server storage device limit, the server adds the device limit indicating the maximum number as a member (such as 20) of the hub network member device. 服务器还保存设备计数,对于添加为成员的每个设备,该设备计数都增加。 The server also saving device count for each device for adding members, the device counts have increased. 如果设备计数已达到设备极限,则服务器不会将客户机设备作为成员添加到集线器网络。 If the device count has reached the limits of the device, the server does the client devices to the hub network as a member. 在备选实现中,服务器不保存设备计数或设备极限,并跳过块1830。 In an alternative implementation, the server does not save device count or a device limit, and block 1830 is skipped. 在另一实现中,可通过来自验证的外部授权机构的请求来修改设备极限。 In another implementation, the device limit can be modified by request from an external authentication authority.

[0109] 如果设备计数低于设备极限,则服务器将客户机设备添加为集线器网络的成员和客户机(块1835)。 [0109] If the device count is below the device limit, the server adds a client device as a member of a hub network and the client (block 1835). 服务器将添加确认消息发送给添加的客户机。 The server will add a confirmation message is sent to the client added. 服务器还将设备计数加 Server device will count is incremented

I。 I. 在一个实现中,服务器将客户机设备添加到成员列表和客户机列表(或同一列表)。 In one implementation, the server adds the client device to the member list and the client list (or the same list). 连接设备、认证设备、授权设备、成员设备、客户机设备和撤消设备列表中的一些或全部可被集成、或相关(对照索引)、或省略。 Connection device, the authentication device, authorized devices, member devices, client devices, and revocation list of devices, some or all may be integrated or related (Control index), or omitted.

[0110] 在备选实现中,在检测时,服务器自动尝试添加检测的客户机设备,或使用一组规则来确定何时尝试添加连接的客户机设备。 [0110] In alternative implementations, upon detection, the server automatically attempts to add detected client devices, or a set of rules to determine when to attempt to add connected client devices. 在另一实现中,服务器自动尝试认证和授权检测的客户机设备,但直到接收到用户请求或批准之后才将认证和授权的设备添加为成员。 In another implementation, the server automatically attempts to detect authentication and authorization client devices, but until it receives only add authentication and authorization for members of the equipment after the user request or approval.

[0111] 在另一实现中,当设备计数已达到设备极限且服务器尝试添加另一设备时,服务器诸如通过外部网络连接来联系设备注册服务器。 [0111] In another implementation, when the device count has reached the device limit and the server is attempting to add another device, such as a server device to contact the registration server via an external network. 设备注册服务器指示是否将客户机设备添加到集线器网络。 Device registration server indicates whether to add the client devices to the hub network. 设备注册服务器保存集线器网络及其成员设备的信息。 Device registration server stores information hub network and its member devices. 设备注册服务器可使用各种标准来确定是否允许添加客户机设备。 Device registration server can use various criteria to determine whether to allow the addition of a client device. 在一个实现中,设备注册服务器将阈值与客户机作为成员添加到的集线器网络的数量相比较。 In one implementation, compared to the number of devices registered with the server threshold value added to the client as a member of the hub network. 在另一实现中,设备注册服务器将已添加到集线器网络的设备数量与第二设备极限相比较,允许在设备计数低于第二设备极限的情况下添加客户机设备。 In another implementation, the device registration server has been added to the number of devices in the hub network is compared with a second device limit, allowing the client device to add in a case where the device count is below the second device limit. 在此情况下,服务器存储的第一设备极限用作在没有外部注册的情况下添加设备的极限,而第二设备极限用作添加设备的最大值。 In this case, the first device limit stored in the server is used as the limit in adding devices without external registration and the second device limit the maximum value of as adding devices. 在另一实现中,在添加设备之前,服务器总是与设备注册服务器协商(例如,好像第一设备极限是O)。 In another implementation, before adding devices, servers always consult with the device registration server (for example, like the first device limit is O).

[0112] 在另一实现中,未连接的设备或本地环境以外的设备可添加为成员。 [0112] In another implementation, an unconnected device other than the device or local environment may be added as a member. 在此情况下,中间设备用作成员资格的“导管(conduit)”。 In this case, the device is used as an intermediate membership "catheter (Conduit)." 服务器和潜在成员客户机不连接,或客户机不在服务器的本地环境中。 Server and the client is not connected to potential members, or client server is not local environment. 中间设备连接到服务器和客户机(例如直接、间接或在不同时间,诸如当中间设备是在服务器和客户机之间移动的便携式设备时)。 The intermediate device is connected to the server and client (e.g., directly, indirectly, or at different times, such as when the intermediate device is a portable device moving between the server and the client when). 中间设备从集线器网络服务器请求允许将客户机添加到集线器网络。 Intermediate server device requests from the network hub to allow the hub network to add the client. 附加过程的工作类似于上述过程,但中间设备在服务器和客户机之间传递消息,而不是服务器和客户机直接通信,其中与各个设备的通信发生在相对于该设备的本地环境中。 Additional working process is similar to the above process, but the intermediate transfer messages between the device server and the client, server and client instead of direct communication, wherein the communication device and each occurrence with respect to the local environment of the device. [0113] 图19示出了将设备作为成员设备从集线器网络移除的一个实现的流程图1900,诸如将存储客户机1720从图17中的集线器网络HNl移除。 [0113] FIG. 19 shows a flowchart of one implementation of the device as a member device 1900 is removed from the hub network, such as a storage client 1720 in FIG. 17 is removed from the hub network HNl. 最初,设备连接到集线器网络,并且是该集线器网络的成员。 Initially, the network device is connected to the hub, and is a member of the hub network. 触发成员客户机设备的移除(块1905)。 Trigger remove members of the client device (block 1905). 在一个实现中,以两种方式触发移除:通过接收来自指定客户机设备的用户的移除请求,或通过确定撤消客户机设备的授权的服务器。 In one implementation, removal is triggered in two ways: by receiving a removal request from a specified user client device, or by determining a client device revoke the authorization server. 在服务器接收到标识客户机的撤消通知时,或服务器确定该客户机设备已回避或违反了顺从性成员设备的集线器网络规则(诸如在绑定实例的状态变为离散时不能禁止子拷贝版本),服务器决定撤消该客户机设备。 When the server receives a notice of withdrawal identify the client or the server determines that the client device has been avoided or violated the rules of compliance hub network member devices (such as sub-copy version can not be disabled in the state to discrete binding instance) the server decided to withdraw the client device. 当服务器确定已危及设备安全时,该服务器也撤消设备的授权。 When the server has determined endanger the safety device, the server also revoke authorized devices.

[0114] 对于要移除的客户机设备,服务器禁止绑定到服务器集线器网络的绑定实例子拷贝版本的许可证(块1910)。 [0114] For to remove the client device, the server license is bound to prohibit bound instance sub-copy version of the hub network server (block 1910). 服务器将禁止请求(其指示要禁止的子拷贝版本)发送给客户机,且该客户机禁止相应许可证。 The server prohibition request (which indicates the sub-copy version to be disabled) to the client, and the client denies the license. 此外,移除的客户机设备将不能接收新的许可证,或刷新绑定到集线器网络(客户机设备从该集线器网络移除)的绑定实例的现有许可证。 Further, the removed client device will not receive a new license, or refresh an existing license is bound to the bound hub network (client device removed from the hub network) is an example. 在一个实现中,一旦客户机已经移除,顺从性客户机设备就自动禁止存储在客户机上的子拷贝版本的所有许可证以及绑定到集线器网络(客户机已从该集线器网络移除)的绑定实例的所有许可证。 In one implementation, once the client has been removed, the compliant client device automatically disables all licenses on the client's sub-copy version of the store and bound to the hub network (client removed from the network hub) of binding instance all licenses. 从一个集线器网络移除客户机并不一定禁止绑定到另一集线器网络的绑定实例的子拷贝版本的许可证。 Remove the client from a hub network is not necessarily bound to prohibit sub-copy version of the binding instance of another hub network license.

[0115] 服务器将客户机设备作为集线器网络成员移除(块1915)。 [0115] Server client device as a member of a hub network is removed (block 1915). 服务器从成员设备列表中移除客户机设备,并减少成员设备计数。 Remove the server from the client device list of member devices, and to reduce device count members. 服务器保存已撤消成员资格设备的撤销列表。 Server keeps a list of revoked the membership has been revoked devices. 当服务器移除撤消的设备时,服务器将该设备添加到服务器的撤消列表中。 Removing revoked when the server device, the server device to the server's revocation list. 如果撤销列表中包括该客户机设备,则服务器不会将该客户机设备添加为成员。 If the revocation list is included in the client device, the server not the client device is added as a member. 在一个实现中,当更新撤消列表时,服务器将撤消列表公布给其它设备,诸如集线器网络中的客户机、其它服务器或中央数据库。 In one implementation, when updating the revocation list, the server revocation list released to other devices, such as client hub network, server or other central database. 在另一实现中,服务器更新存储在服务器上的一个或多个根许可证,来指示已经撤消了该客户机。 In another implementation, the server updates one or more storage on the server's root license, to indicate that the client has been revoked.

[0116] 在一个实现中,直到存储在客户机上的子拷贝的所有许可证都已经到期,服务器才将断开的客户机作为成员移除。 [0116] In one implementation, all licenses until the child is stored on the client copies have already expired, the server was disconnected client as a member removed. 如下所述,当断开设备时,来自断开的集线器网络的许可证将最后到期。 As described below, when the device is disconnected, licenses from the disconnected hub network will finally expire. 服务器等待完成断开设备的移除,直到所有那些许可证到期为止。 Disconnect the server waits for the completion of the removal device, until all those license expires.

[0117] 设备断开和重新连接 [0117] disconnect and reconnect equipment

[0118] 当设备进入集线器网络的本地环境时,该设备可连接到该集线器网络。 [0118] When a device enters the local environment of the hub network, the device can be connected to the hub network. 当设备离开集线器网络的本地环境时,该设备从该集线器网络中断开。 When a device leaves the local environment of the hub network, the device is disconnected from the hub network. 当设备返回该本地环境时,该设备可重新连接到该集线器网络。 When the device returns to the local environment, the device can reconnect to the hub network. 如上所述,当顺从性非成员连接或重新连接到集线器网络时,在接收到来自用户的请求或批准之后,服务器继续尝试添加新的设备。 As described above, when a compliant non-member is connected or reconnected to the hub network, after receiving a request or approval from a user, the server continues to try to add a new device.

[0119] 图20示出了从集线器网络断开成员设备的一个实现的流程图2000。 [0119] FIG. 20 shows a flowchart 2000 of one implementation of disconnecting a member device from a hub network. 最初,连接的设备变为断开(块2005)。 Initially, the connected device is turned off (block 2005). 可以各种方式断开设备。 You can disconnect the device in various ways. 当设备离开集线器网络的本地环境时,该设备从该集线器网络断开。 When a device leaves the local environment of the hub network, the device is disconnected from the hub network. 当设备和集线器网络之间的物理连接(无线或有线)失效时,该设备断开。 When the physical connection between the device and the hub network (wireless or wired) fails, the device is disconnected. 例如,当服务器和客户机不再能交换数据包时,客户机和服务器断开。 For example, when the server and client can no longer exchange packets of data, the client and server is disconnected. 在一个实现中,服务器确定在需要时(例如,在基于连接的客户机操作之前)是否连接客户机。 In one implementation, the server determines if required (e.g., prior to the operation based on the client connection) is connected clients. 在另一实现中,服务器周期性地为连接轮询客户机,并保存连接的设备列表,并且客户机还周期性地轮询服务器,并确认何时断开客户机。 In another implementation, the server periodically polls clients for connection, and store a list of connected devices, and the client also periodically polls the server and confirm when the client has disconnected. 在另一实现中,当用户肯定地请求断开设备时,断开该设备。 In another implementation, when a user affirmatively requests to disconnect the device, disconnect the device. [0120] 由于相对于服务器位置(例如在服务器的100米内)定义本地环境,因此服务器不会离开本地环境,这是因为当服务器物理上移动时,服务器带着本地环境。 [0120] Since the relative position of the server (e.g., within 100 meters of the server) definition of the local environment, the server will not leave the local environment because the server when the physical movement, the local environment with the server. 然而,当服务器移动时,作为服务器移动的结果,集线器网络的一个或多个客户机可能不移动,并因此可能“离开”该集线器网络的本地环境。 However, when the server moves, as a result of moving a server, a network hub or more clients may not be moved, and thus may be "leave" the local environment of the hub network. 在此情况下,由于留下的客户机在本地环境的以外,因此从集线器网络断开。 In this case, since leaving the client outside the local environment, so disconnected from the hub network.

[0121] 客户机检查绑定到集线器网络的绑定实例的子拷贝版本的任何许可证的截止周期(块2010)。 [0121] The client checks binding instance is bound to the hub network sub-copy version of any off period (block 2010) license. 如下所述,子拷贝版本的许可证包括截止周期。 As described below, the sub-copy version includes a license off period. 当客户机接收到许可证时,该客户机基于许可证的截止周期设置截止时间。 When the client receives the license, the client set the off period deadline based license. 例如,对于截止周期为15天的许可证,客户将截止时间设为从客户机接收到许可证时起的15天。 For example, for a period of 15 days as of the license, the customer will be the deadline to 15 days from the time received from the client to the license. 客户机使用安全时钟监控到截止时间还剩多长时间,以及何时已达到截止时间。 The client uses the clock security monitoring left to the deadline for how long, and when it has reached the cut-off time. 客户机通过请求来自服务器的刷新许可证来周期性地刷新许可证,并且当接收到刷新许可证时,重新设置截止周期和时间。 It refreshes the license by requesting client from the server to refresh the license periodically, and when receiving the refresh licenses, and re-set the off period time. 断开的客户设备不能刷新许可证,因为客户机没连接到服务器。 Disconnect the client device can not refresh the license, because the client did not connect to the server. 虽然客户机不能刷新许可证,但截止时间不改变,因此到达截止时间的时间量继续减少。 Although the client can not refresh the license, but does not change the deadline, so the amount of time to reach the deadline continued to decline. 当达到截止时间时,截止周期已到期,并且客户机禁止许可证。 When the deadline is reached, off period has expired, and the client license is prohibited. 当客户机又能刷新许可证时,客户机启动许可证,并重新设置截止时间。 When the client can refresh the license, permit the client to start, and re-set deadline. 由于客户机从许可证的集线器网络断开了,所以客户机可能不能刷新一个许可证,但由于客户机仍连接到对应于第二许可证的不同集线器网络,所以能刷新第二许可证。 Since the client is disconnected from the hub network license, so the client may not be able to refresh a license, but because the client is still connected to a different hub network corresponds to a second license, we are able to refresh the second license.

[0122] 如果任何截止周期都已到期,则客户机禁止具有这些截止周期的许可证(块2015)。 [0122] If any cutoff period have expired, the client licenses prohibit these cut-off period (block 2015) have. 客户机禁止许可证,禁止相应的子拷贝版本。 The client license is prohibited, prohibited the corresponding sub-copy version. 在另一实现中,客户机以另一方式禁止子拷贝版本,如下所述。 In another implementation, the client is prohibited in another embodiment the sub-copy version, as described below.

[0123] 客户机周期性地检查,以查看客户机是否已重新连接到集线器网络(块2020)。 [0123] The client periodically checks to see if the client has been reconnected to the hub network (block 2020). 在一个实现中,当请求刷新的许可证时,客户机同时检查重新连接。 In one implementation, when the refresh request a license, the client while checking reconnect. 在一些配置中,诸如对于使用有线连接的一个实现,由于客户机迅速接收指示重新连接的信号,因此该客户机不必周期性地检查重新连接,并因此可跳过块2020。 In some configurations, such as for one implementation using a wired connection, because the client quickly receives a signal indicating the reconnection, so that the client does not have to check periodically reconnected, and thus block 2020 may be skipped. 当客户机重新连接到集线器网络时,该客户机遵循图21中所示的过程。 When the client reconnects to the hub network, the client follows the process shown in FIG. 21.

[0124] 图21示出了将成员设备重新连接到集线器网络的一个实现的流程图2100。 [0124] FIG. 21 shows a flowchart 2100 of one implementation of reconnecting a member device to a hub network. 最初,该设备是已从集线器网络断开的成员设备。 Initially, the device is disconnected from the hub network member devices. 然后该设备重新连接到集线器网络(块2105)。 The device is then reconnected to the hub network (block 2105). 当设备在集线器网络的本地环境中、并且恢复或建立了设备和集线器网络之间的物理连接时,可重新连接该设备。 Equipment in the local environment of the hub network, and when the restoration or establishment of the physical connection between the hub and the network connection device, when the device can reconnect. 在一个实现中,客户机周期性地轮询服务器,并确认何时重新连接该客户机。 In one implementation, the client periodically polls the server and determine when the client is reconnected. 在一个实现中,直到用户请求这么做时,设备才重新连接。 In one implementation, the time until the user requests to do so, before reconnecting the device.

[0125] 服务器检测集线器网络中的重新连接的设备(块2110)。 [0125] hub network server detects the reconnected device (block 2110). 在一个实现中,客户机将重新连接通知发送给服务器。 In one implementation, the client will reconnect the notification is sent to the server. 如上面参考图18的块1810所描述的,在另一实现中,服务器为新连接或重新连接的设备周期性地轮询集线器网络。 As described above with reference to FIG 181,018 of the block, and in another implementation, the server for the new connection or reconnection device periodically polls the hub network.

[0126] 服务器认证检测的设备,并检查重新连接的设备是否是集线器网络的成员客户机(块2115)。 If [0126] the server certification testing device, checking the reconnected device is a member client of the hub network (block 2115). 如上面参考图18的块1815所描述的,服务器认证连接的设备,以确定设备身份。 As represented by block 1815 above with reference to FIG. 18 described, the authentication server connected to the device to determine the device identity. 服务器保存成员设备列表,并因此能够确认新连接的设备已是集线器网络的成员,并不需要再次添加。 Save the list of members of the server equipment, and therefore able to confirm the new device is connected to a member of the hub network, you do not need to be added again. 在一个实现中,服务器确认重新连接的设备在集线器网络的本地环境中。 In one implementation, the server confirms that the reconnected device local environment of the hub network. 在一个实现中,服务器还确认重新连接的设备不在撤消列表上。 In one implementation, the server also confirms reconnected device is not on the revocation list.

[0127] 在将设备认证为成员设备之后,服务器刷新客户机的许可证(块2120)。 [0127] After the authentication device as a member device, refresh the license server clients (block 2120). 对于绑定到服务器的集线器网络的绑定实例,服务器刷新存储在客户机上的内容数据的子拷贝版本的许可证。 For instance bound to the binding hub network server, the server refresh sub-copy version of the content data stored on the client's license. 服务器并不刷新绑定到其它集线器网络的绑定实例的子拷贝版本的许可证。 Refresh server does not bind to the sub-copy version of the binding instance the other hub network license. 备选地,一旦客户机已成功重新连接到集线器网络,该客户机就请求刷新许可证。 Alternatively, once the client has successfully reconnected to the hub network, the client will request a refresh license.

[0128] 时间管理 [0128] Time Management

[0129] 服务器管理集线器网络的时间管理。 [0129] Time management server hub of the network. 时间管理包括相对时间和绝对时间管理。 Time Management includes the relative time and absolute time management. 月艮务器管理时间,以实施诸如在集线器网络中内容的离散或绑定实例的许可证中基于时间的限制。 May that works to manage time to implement time-based license restrictions such as discrete or bindings content hub network instance. 客户机还在内部管理时间,或根据服务器的时间管理来管理时间。 The client also internal management time, or based on time management server to manage time. 当客户机从许可授权机构接收子拷贝版本的许可证时,在接收许可证之前客户机将时间信息与许可授权同步。 When a client receives a license from the licensing authority of the sub-copy version, before receiving a license client will synchronize time information and licensing. 服务器和客户机使用管理时间的安全机制。 Servers and clients use the security mechanism time management.

[0130] [0130]

[0131] 在一个实现中,集线器网络设备使用各种操作的安全技术,包括(但不限于)••传递数据;发出请求;记录事务历史的事务;提供和禁止许可证;认证、授权、禁止和撤消设备;存储、产生和移动实例、拷贝和密钥;保存实例和拷贝的元数据;以及呈现和流内容。 [0131] In one implementation, network device security technology hub various operations, including (but not limited to) •• transfer transactions; request; transaction history record of the transaction; providing and disabling licenses; authentication, authorization, prohibiting and revoking devices; storing, generating, and moving instances, copies and keys; examples and metadata stored copy; and presenting and streaming content. 顺从性设备可周期性地更新来自中央授权机构的安全过程,或接收来自用户或自动源的更新。 Compliant device may periodically updating the security process from the central authority, or receive updates from a user or automated source. 客户机设备在接收许可证之前更新安全机制,包括诸如更新加密密钥、使客户机的时钟和时间信息与服务器同步、交换和更新撤消列表以及更新系统安全数据和工具的机制。 The client device update security before receiving a license, including updates such as encryption keys, and the clock time information with server-client synchronization, exchange and update mechanism for updating revocation lists and data security systems and tools. 在一个实现中,如果服务器已确定危及了密钥,则服务器可撤消该密钥。 In one implementation, if the server has determined the key compromise, the server can revoke the keys. 在此情况下,服务器请求顺从性设备禁止撤销的密钥,以使撤消的密钥不将用于访问安全媒体内容。 In this case, the server request key revocation prohibited compliant device, so that the key is not revoked used to access secure media content.

[0132] 内容管理 [0132] Content Management

[0133] 媒体网络环境中的设备呈现、拷贝和移动内容实例的内容数据。 [0133] The media presentation device in a network environment, the content data copying and movement of content instances. 如上所述,实例包括是诸如音频和/或视频数据的媒体数据的内容数据。 As described above, examples include such as audio and / or data content of the video data of the media data. 如上所述,集线器网络的服务器管理集线器网络中内容的绑定实例的状态。 As described above, the state of bound instances of the server management hub hub network content. 服务器直接改变绑定实例的状态,并使集线器网络中的成员客户机根据这些状态改变采取适当行动。 Server directly change the state of binding instance, and a member of the hub network client change to take appropriate action in accordance with these states.

[0134] 内容的实例是顺从性或非顺从性的。 Examples [0134] content was in compliance or non-compliance. 顺从性实例包括编码的数据,以使只有顺从性设备能够解码和呈现内容数据。 Examples include compliant data encoded so that only compliant devices can decode and render the content data. 相应地,非顺从性设备不能呈现来自顺从性实例的内容数据。 Accordingly, non-compliant devices can not present content data from a compliant instance. 顺从性设备(服务器)可将顺从性实例绑定到集线器网络,或从集线器网络中释放顺从性实例。 Compliant device (server) can be bound to a compliant instance of a network hub, or released from the hub compliant network examples.

[0135] 根据集线器网络的要求,不对内容的非顺从性实例或拷贝编码,并因此非顺从性设备或顺从性设备可呈现非顺从性实例或拷贝的内容数据(受可存在于实例或拷贝中的其它拷贝控制机制的控制)。 [0135] The requirements of a hub network, the non-compliant instance or copy of the encoded right content, and therefore non-compliant device or a compliant device can present the content data of a non-compliant instance or copy (subject to be present in the instance or copy other control copy control mechanisms). 顺从性设备不会将非顺从性实例或拷贝绑定到集线器网络,但可以备选形式存储非顺从性内容。 Compliant device will not copy a non-compliant instance or bound to the hub network, but can store non-compliant content alternative forms. 在一个实现中,如果非顺从性实例具有顺从性设备识别的、并被授权用在集线器网络中的拷贝控制信息,则该顺从性设备可根据拷贝控制信息来绑定定义根许可证的非顺从性实例。 In one implementation, if a non-compliant instance has compliant device identification, copy control information in a network hub and authorized, the compliant device can bind to define the root license according to the non-compliant copy control information examples.

[0136] 内容状杰 [0136] content like Jay

[0137] 集线器网络中内容的每个顺从性实例都处于两种互斥状态的其中一种:离散或绑定。 Wherein [0137] Each compliant instance of content in the hub network are in a state of two mutually exclusive: discrete or bound. 内容的离散实例不绑定到任何集线器网络,并可使用顺从性媒体在集线器网络中或集线器网络外从一个设备移到另一设备。 Examples of the discrete content is not bound to any hub network, using compliant media and the network at the hub or the external hub is moved from one network device to another. 顺从性设备不会产生离散实例的拷贝(除在呈现内容数据过程中的瞬变以外)。 Compliant device will not copy a discrete instance (other than the transient data during the presentation of the content). 离散实例可以各种形式,诸如存储在顺从性存储媒体(例如光盘)上的一个或多个电子文件,或存储在顺从性设备的存储器中的一个或多个电子文件(例如,经网络连接通过下载所接收的)。 Examples which may be discrete in various forms, such as one or more electronic files or in the memory device in compliance with one or more electronic files stored on compliant storage media (e.g., disk) storage (e.g., over a network connection Download received). 存储内容离散实例的媒体是媒体网络顺从性媒体。 Examples of media content stored in discrete media network is compliant media. 顺从性媒体允许服务器按需要修改离散实例,诸如在将内容绑定到集线器网络时禁止离散实例。 Compliant media server as needed to allow modification of discrete instances, such as the prohibition of discrete instances when the content is bound to the hub network. 此外,配置顺从性媒体,以使设备不能创建存储在顺从性媒体上的任何离散实例数据的逐位拷贝。 In addition, compliant media configuration, so that the device can not create a discrete instance bitwise copy of any data stored on the compliant media. 相应地,顺从性媒体是或包括安全读/写存储媒体(例如,具有附加或相关可写存储器的可写光盘或只读媒体)。 Accordingly, compliant media is or includes secure read / write storage media (e.g., associated with an additional writable memory or writable or read-only optical disc medium). 在一个实现中,可写存储器远离媒体其自身,诸如数据库。 In one implementation, remote from the writable memory medium itself, such as a database. 顺从性设备不会创建离散实例的拷贝。 Compliant device does not create a copy of discrete instances.

[0138] 图22示出了离散实例2205的一个实现的表示。 [0138] FIG. 22 shows an example of a discrete representation 2205 implemented. 离散实例2205包括锁定或安全内容数据(例如加密的)2210。 Examples include a locking or 2205 discrete secure content data (e.g., encrypted) 2210. 离散实例的锁定内容数据也称为该离散实例的锁定内容数据的离散版本。 Examples of discrete locked content data, also known as the discrete locking instance discrete version of the content data. 锁定内容数据2210是离散实例的媒体内容数据,诸如音频或视频数据(例如歌曲、电视节目、电影)。 Locked content data 2210 is an example of a discrete media content data, such as audio or video data (such as songs, TV shows, movies). 在备选实现中,锁定内容数据是非媒体数据,诸如可执行软件(例如计算机或视频游戏)。 In alternative implementations, the locking of the content data is non-media data, such as executable software (e.g., computer or video game). 锁定内容数据2210被加密(例如,使用通过公共同级评审发布并验证的一个或多个密码算法)。 Locked content data 2210 is encrypted (e.g., using one or more cryptographic algorithms released through public peer review and validation). 使用内容加密技术将锁定内容数据2210加密,以使只有顺从性设备可解密锁定内容数据2210。 Using a content encryption technique locked content data 2210 is encrypted so that only compliant devices can decrypt the locked content data 2210. 标题信息2215与锁定内容数据相关联。 Header information 2215 content data associated with the lock. 标题信息包括诸如标题标识符、实例标识符(标识具体实例)、编码数据(例如,指示编解码器、分辨率(resolution)以及用于将锁定内容数据编码的编码实体)和许可授权数据的元数据。 Cell header includes information such as a title identifier, an instance identifier (identifying the specific instance), encoding data (e.g., indicating the codec, resolution (Resolution) for locking and coding entity coded content data), and licensing data data. 许可授权数据指示可被访问以获取附加权限或许可证的外部许可授权机构。 Licensing data indicate can be accessed for external licensing authority additional rights or licenses. 离散实例的一些实现并不包括许可授权数据(例如,与锁定内容数据一起提供使用任何许可证)。 Some examples of Discrete does not include licensing data (for example, locking content data together with any license). 在另一实现中,标题信息2215中的一些或全部被加密,或被包含在锁定内容数据2210中。 In another implementation, the header information 2215 is encrypted some or all of, or contained in a locked content data 2210. 离散实例2205包括加密数据的安全区2220。 Examples include discrete security zones of encrypted data 2205 2220. 使用集线器网络加密技术,对安全区2220的数据加密,以使只有顺从性设备能够将安全区2220的数据解密(例如,使用顺从性设备拥有的密钥)。 Using hub network encryption, secure data encryption region 2220, so that only compliant devices the data can be decrypted secure area 2220 (e.g., using a key owned compliant device). 安全区2220包括密钥2225、离散许可证2230和撤销列表2235。 District 2220 includes key security 2225, 2230 and discrete license revocation list 2235. 密钥2225用于解开锁定内容数据2210。 2225 key for unlocking content data 2210. 在一个示例中,顺从性设备拥有对包括密钥2225的安全区2220 (其是使用集线器网络加密术加密的)解密的密钥,并使用密钥2225对锁定内容数据2210 (其是使用内容加密术加密的)解密。 In one example, data compliant device has a secure area key 2225 2220 (which is a hub network encryption technique using encryption) key is decrypted using the content key lock 2225 2210 (which is encrypted using a content surgery encrypted) decryption. 离散许可证2230拥有特定离散实例2205的锁定内容数据2210的当前许可证。 Discrete license 2230 have a current license to target specific discrete instance of content data 2205 2210. 许可证2230定义为特定离散实例2205的锁定内容数据2210定义的允许集,包括在适当时(例如不允许拷贝时)对于离散实例的呈现、拷贝和移动。 License 2230 defines locked content data 2210 for the particular defined set of allowed discrete instance 2205, including when appropriate (e.g., copying is not permitted) for a discrete instance of presentation, copying and moving. 许可证2230还基于离散实例2205指示可用于绑定实例的许可证类型。 License 2230 is also based on the discrete instance 2205 can be used to indicate the type of binding instance license. 在一个实现中,许可证2230包括指示离散实例2205是离散实例的标记。 In one implementation, the license 2230 includes a flag indicating a discrete instance 2205 is a discrete instance. 撤消列表2235指示已经撤销了授权的设备。 2235 indicates the revocation list already withdrawn authorized devices. 顺从性设备保存其自己的撤消列表。 Compliant device holds its own revocation list. 当顺从性设备接收离散实例时,该设备将不在设备撤消列表上的离散实例的撤销列表中的任何设备添加到其撤销列表上。 When the device revocation list any compliant device receives a discrete instance, the device will not undo the discrete instance on the device list is added to the revocation list thereof. 如果在顺从性设备的撤销列表中没列出该设备,则该顺从性设备不会呈现或播放离散实例。 If the device is not listed in the revocation list of compliant devices, the device does not render compliance or play discrete instances. 如果顺从性服务器的撤销列表中没列出该服务器,则该顺从性服务器不会绑定离散实例。 If the revocation list of compliant server did not list the server, the server does not bind compliance discrete instances. 在另一实现中,离散实例不包含撤消列表。 In another implementation, the discrete instance does not contain revocation list. 在另一实现中,离散实例的部件存储为多个文件。 In another implementation, the storage means into a plurality of discrete files instance.

[0139] 绑定实例绑定到特定集线器网络,并由该集线器网络的服务器管理。 [0139] Examples of binding to a specific binding hub network, hub network by the management server. 绑定实例的数据被加密(至少部分被加密),以使非顺从性设备或绑定集线器外部的设备不能够呈现或播放绑定实例的内容数据。 Examples of the binding data is encrypted (at least in part encrypted) to the external device or the non-compliant device can bind the hub does not present or play a bound instance of content data. 管理绑定实例的服务器具有该绑定实例的根职责。 Server Management binding instance has the binding instance root duties. 根职责包括颁发和管理绑定实例的锁定内容数据的子拷贝版本的许可证。 Root responsibilities include the issuance and administration of the binding sub-copy version of locked content data license instance. 管理绑定实例的服务器还管理绑定实例锁定内容数据的源版本。 Server Management binding instance also manages the binding instance locking version of the content source data. 服务器使用该源版本创建集线器网络中锁定内容数据的子拷贝版本。 The server uses the source version to create a hub network in the sub-copy version of locked content data. 指定的服务器是该绑定实例的子拷贝版本的本地许可授权机构。 The specified server is the binding instance sub-copy version of the local licensing authority. 该服务器可从源版本产生子拷贝版本,并将子拷贝版本提供给集线器网络中的客户机。 The server may generate a sub-copy version from the source version and provide the sub-copy versions to clients in the hub network. 在一个实现中,客户机还可从客户机存储的子拷贝版本中产生子拷贝版本,但接收新子拷贝版本的客户机需要来自集线器网络服务器的许可证,以呈现内容。 In one implementation, the client can also be generated from the sub-copy version of the client is stored in the sub-copy version, but receive a new sub-copy version of the client network hub requires a license from the server to render the content. 客户机设备可将子拷贝版本移到集线器网络中的另一设备,或集线器网络外部的设备。 The client device may be sub-copy version to another device in the hub network, hub network or external device. 接收来自不同集线器网络(例如,设备不是其成员的集线器网络)的子拷贝版本的设备需要诸如从子拷贝版本指示的许可授权机构获得新的许可证。 Receiving sub-copy version of the device from a different hub network (eg, the device is not a member of the hub network) such as the need to obtain a new license from the licensing authority indicated sub-copy version. 在没有首先将绑定实例的状态改回离散的情况下,顺从性服务器不会将根职责以及由此的绑定实例移到另一顺从性服务器。 In the state without first binding instance the case back to discrete, compliance will not root server functions and thus the binding instance to another server compliance. 为了将根职责传到另一服务器,服务器将绑定实例转换为离散实例,并将离散实例移到第二服务器。 In order to spread root responsibility to another server, the server converts the bound instance to a discrete instance and moves the discrete instance of the second server. 然后第二服务器将接收的离散实例转换为绑定实例,并因此第二服务器随后具有根职责。 The second server then converts the received discrete instance to bound instance, and so the second server then has root responsibility. 在此情况下,绑定实例然后绑定到不同的集线器网络(第二服务器的集线器网络)。 In this case, the bound instance is then bound to a different hub network (a second network hub server). 在另一实现中,源版本没有存储在集线器网络的服务器上,但服务器存储和管理根许可证,并远程管理源版本。 In another implementation, the source version is not on the server hub of the network, but the server root license to store and manage storage, and remote management source version.

[0140] 图23示出了绑定实例2300的一个实现的表示,包括存储在服务器2305和客户机2350上的部件。 [0140] FIG. 23 illustrates an implementation 2300 binding instance representation, including components stored on the server 2305 and the client 2350. 绑定实例2300的结构与图22中的离散实例2205类似,但可包括存储在服务器上的数据和存储在集线器网络中的O个或多个客户机上的数据。 Examples of binding structure as 2300 in FIG. 22 is similar to the discrete instance 2205, but may include data on one or more client data store and stored on the server in a hub network O. 服务器部件2305包括:锁定内容数据2310、标题信息2315和安全区2320,安全区包括密钥2325、根许可证2330和撤消列表2335。 Server 2305 components include: locked content data 2310, header information 2315 and 2320 security area, the security area includes a key 2325, root license revocation lists 2335 and 2330. 服务器部件2305中的锁定内容数据2310是绑定实例2300的锁定内容数据的源版本。 Locked content data 2305 in the server components 2310 is bound instance 2300 locked content data source version. 服务器使用该源版本,以产生锁定内容数据(例如,下面讨论的锁定内容数据2310)的子拷贝版本。 The server uses the source version of locked content data to generate (e.g., locked content data 2310 discussed below) in the sub-copy version. 源版本是集线器网络中内容的最高分辨率版本。 Source version is the highest resolution version hub network content. 如果不同设备请求不同分辨率拷贝,则可从源版本产生这些拷贝。 If different devices request different resolution copies, those copies can be generated from the source version. 标题信息2315的许可授权数据指示外部许可授权机构(例如,与绑定实例基于的离散实例所指示的授权机构相同的授权机构),以及作为本地许可授权机构的服务器。 Header information 2315 indicates an external licensing licensing authority data (e.g., discrete instance authority based binding instance indicated by the same authority), and the server as a local licensing authority. 绑定实例的一些实现不包括绝对许可授权数据(例如,使用与锁定内容数据一起提供的任何许可证)。 Binding instance some implementations do not include (any license for example, the use of locking content data together) absolutely licensing data. 根许可证2330指示为特定锁定内容数据2310定义的允许集,包括适当时对绑定实例的呈现、拷贝和移动(例如,不允许移动,但允许创建子拷贝版本并将其提供给其它设备)。 Root license 2330 indicates the specific data content lock 2310 allows the definition set when rendered comprise suitable binding instance, copying and moving (e.g., a mobile is not allowed, but allows to create the sub-copy version and provide it to other devices) . 根许可证2330被密码地绑定到特定服务器。 Root license 2330 is cryptographically bound to a specific server. 根许可证2330定义什么类型许可证可用于集线器网络中的子拷贝。 Root license 2330 defines what types of licenses are available for sub-copies in the hub network. 在一个实现中,根许可证2330包括指示绑定实例2305是绑定实例的标记。 In one implementation, the root license 2330 includes an indication 2305 binding instance is labeled binding instance. 在一个实现中,根许可证是不同的,这取决于服务器是服务器设备还是服务器/客户机设备。 In one implementation, the root license is different, depending on the server is the server device or server / client device. 撤销列表指示已经撤消授权的设备。 It has revoked the revocation list indicates authorized devices. 如上所述,顺从性设备保存其自身的撤消列表(例如,服务器保存服务器或设备撤销列表,客户机保存客户机撤消列表)。 As described above, a compliant device holds its own revocation list (e.g., a server or device revocation list storage server, the client saves the client revocation list). 当服务器接收绑定实例时,服务器将不在服务器撤消列表上的绑定实例的撤销列表中的任何设备添加到其撤销列表。 Any device revocation list when the server receives a bound instance, the server will not revoke the server instance bound on the list to add it in the revocation list. 如果服务器的撤销列表中列出了顺从性服务器设备,则该设备不会呈现或播放绑定实例。 If you list the compliance server device revocation list server, then the device does not appear or play binding instance. 如果服务器的撤销列表中列出了顺从性服务器,则该服务器不会解除(使离散)绑定实例。 If you list the compliance server revocation list server, then the server will not lift (the dispersion) binding instance. 顺从性服务器不会将子拷贝版本或许可证提供给在服务器撤销列表中列出的设备。 Compliant server does not provide a license or sub-copy version to the device listed in the server revocation list. 在另一实现中,顺从性服务器会将子拷贝版本提供给撤销列表中列出的设备,但不将许可证提供给该设备。 In another implementation, the compliance server sub-copy version will be provided to the equipment listed in the revocation list, but does not provide a license to the device.

[0141] 存储在客户机2350上的部件类似于存储在服务器2305上的部件,但许可证不同。 [0141] member is stored on a client 2350 are similar to member 2305 stored on the server, but with different licenses. 客户机部件2350包括:锁定内容数据2355、标题信息2360以及包括密钥2370、子拷贝许可证2375和撤销列表2380的安全区2365。 The client component 2350 includes: locked content data 2355, header information 2360 and 2380, including key safety zone 2370, 2375 and sub-copy license revocation list 2365. 标题信息2360的许可授权数据指示外部许可授权机构(例如,由绑定实例基于的离散实例所指示的同一授权机构)以及对应于绑定实例的、作为本地许可授权机构的服务器。 Header information 2360 indicates an external licensing licensing authority data (e.g., the same authority based on the discrete instance is bound instance as indicated) and corresponding to the bound instance as a local licensing authority server. 如上所述,绑定实例的一些实现不包括许可授权数据。 As noted above, binding instance, some implementations do not include licensing data. 子拷贝许可证2375根据相应绑定实例的根许可证来指示为特定锁定内容数据2355定义的允许集,包括呈现内容的规则,诸如任何时间约束。 Sub-copy license 2375 according to the root license of the corresponding bound instance to indicate locked content data 2355 for a particular set of defined allowable, presenting content including rules, such as any time constraint. 子拷贝许可证2375密码地绑定到特定客户机。 Sub-copy license 2375 is cryptographically bound to a particular client. 子拷贝许可证2375包括客户机何时不能刷新许可证的截止周期,如下所述。 Sub-copy license 2375 includes a cut-off when the client can not refresh the license period, as described below. 如上所述,客户机设备保存撤销列表,并根据撤消列表2380更新该撤销列表。 As mentioned above, the client device holds revocation list and the revocation list updated according to the 2380 revocation list. 如果在客户机的撤销列表中列出了顺从性客户机设备,则该设备不会呈现或播放子拷贝版本。 If the client lists of compliant equipment in the client's revocation list, the device does not appear or play sub-copy version. 在一个实现中,顺从性设备也不会将子拷贝提供给在客户机的撤销列表中列出的设备。 In one implementation, the sub-compliant device will not provide copies to the device listed in the client's revocation list.

[0142] 在一个实现中,类似于离散实例,使用不同技术对绑定实例的锁定内容数据和安全区加密。 [0142] In one implementation, similar to the discrete instance, the locking of the content data and encryption security zone binding instance using different techniques. 使用内容加密技术,将锁定内容数据(源版本和任何子拷贝版本)加密。 Using a content encryption technique, the locked content data (the source version and any sub-copy versions) is encrypted. 使用集线器网络加密技术,将安全区加密。 Using a hub network encryption technology, encryption security zone. 在一个示例中,顺从性设备拥有集线器网络密钥,用以对包含密钥的安全区(其是使用集线器网络加密术加密的)解密,并使用来自安全区的解密密钥对锁定内容数据(其是使用内容加密术加密的)解密。 In one example, a compliant device has a hub network key for the lock to secure the data area contains the content key (which is encrypted using a hub network encryption technique) is decrypted using the decryption key from the security zone ( it is encrypted using a content encryption) decrypt.

[0143] 在另一实现中,可独立管理和分配绑定实例的锁定内容数据和许可证(或整个安全区)。 [0143] In another implementation, management and distribution of independently binding instance locking the content data and a license (or the entire secure area). 类似地,可独立分配离散实例的锁定内容。 Similarly, the content may be independently assigned locking discrete instance. 在此情况下,在没有先获得有效许可证的情况下,顺从性设备不会呈现锁定内容数据。 In this case, without first obtaining a valid license, the compliant device will not appear locked content data. 设备可在集线器网络之外分配锁定内容数据,但接受者仍将需要新许可证。 Equipment can be assigned locked content data outside the network hub, but the recipient will need a new license. 此外,以这种方式,中间设备可用作导管,用以通过将许可证从服务器传到断开的客户机来刷新集线器网络本地环境之外的断开的成员设备的许可证,如下所述。 Moreover, in this way, the device can be used as an intermediate conduit for refreshing a license to a disconnected member device outside the local environment of the hub network from a license server by the spread disconnected client, as described below .

[0144] 相同内容的多个离散实例被视为截然不同的离散实例,并且这些离散实例不相关。 [0144] a plurality of discrete instances of the same content are treated as distinct discrete instances and are not related to the discrete instance. 类似地,如果相同内容的多个离散实例绑定到集线器网络,则每个都创建截然不同的绑定实例。 Similarly, if a plurality of discrete binding instances of the same content to a network hub, then each created distinct binding instance. 在另一实现中,服务器识别何时存在相同内容的多个离散实例(例如,通过标识内容中的信息或标题信息),并且实例的许可信息允许绑定实例被视为相关的。 A plurality of discrete instances in another implementation, the server recognizes when the presence of the same content (e.g., title information or by identifying the information content) is considered as relevant, and examples of the permission information permits the binding instance. 例如,如果存在多个相关实例,则释放一个相关实例不需要禁止其余相关绑定实例的锁定内容数据。 For example, if multiple related instances exist, the associated release of a bound instance Disabling remaining locked content data related instances.

[0145] 在另一实现中,内容的实例或拷贝也可处于第三种状态:无限制的。 [0145] In another implementation, an instance or copy of content can be in a third state: unlimited. 在集线器网络之内或之外,无限制的实例和拷贝可被移动、拷贝和播放。 Within or outside the hub network, and unlimited examples of copies can be moved, copied, and played. 顺从性设备不会将无限制实例的状态变为绑定或离散。 Compliance status of the device will not bind or become unrestricted instance discrete. 当用户请求将内容添加到集线器网络时,如果服务器标识受控状态(其根据拷贝控制信息定义根许可证),则服务器检查拷贝控制信息,并将内容添加为绑定实例。 When the user requests to add content to the hub network if the server identifies controlled conditions (which according to the control information defining a copy of the root license), the server checks the copy control information and the contents added as binding instance. 如果用户请求添加不包含任何检测的拷贝控制或媒体网络环境信息的实例(例如,不是离散或绑定实例),则设备可将内容添加为无限制实例。 If the user requests to add the copy control without instances or media network environment information of any detected (e.g., not a discrete or bound instance), the device can add the content as unlimited examples.

[0146] 返回图17,两个内容条目A和B绑定到集线器网络HN1。 [0146] Returning to Figure 17, two content items A and B are bound to the hub network HN1. 对于两个内容条目A和B中每一个的绑定实例,服务器/客户机设备1705存储锁定内容数据的源版本(由“A”和“B”标号指示)。 For each of the two binding instance content items A and B, the server / client device 1705 stores a source version of locked content data (by "A" and "B" numerals). 存储客户机设备1720存储两个内容条目A和B中每一个的锁定内容数据的子拷贝版本(由“a”和“b”标号指示)。 Storage client device entries A and B of each of the sub-copy versions of content data (the "a" and "b" indicate reference numeral) storing two content lock 1720.

[0147] 一个内容条目X绑定到集线器网络HN2。 [0147] a content item X is bound to the hub network HN2. 服务器设备1715存储内容X的源版本(由“X”标号指示)。 The server device 1715 stores a source version of content X (indicated by "X" numerals). 服务器/客户机设备1705和存储客户机设备1720每个都存储内容条目X的子拷贝版本(由“X”标号指示)。 The server / client device 1705 and the storage client device 1720 each store sub-copy versions of content items X (indicated by "X" numerals). 服务器设备1715还存储内容Y的离散实例的锁定内容数据的离散版本(由“I”标号指示)。 Examples of discrete locked content data server device 1715 also stores a discrete version of the content Y (from the "I" numerals).

[0148] 存储设备1730存储内容Z的离散版本(由“Z”标号指示)。 Content storage 1730 [0148] The discrete version of the storage device Z (the "Z" numerals).

[0149] 内容状态转变 [0149] SUMMARY state transitions

[0150] 服务器管理在集线器网络中内容的顺从性实例的状态。 [0150] Examples of compliance status management server in the content of the hub network. 服务器通过将离散实例的状态变为绑定来将实例绑定到集线器网络。 The state of the discrete instances by the server becomes bound to the bound instance to a hub network. 服务器通过将绑定实例的状态变为离散并禁止集线器网络中相应的锁定内容数据,来从集线器网络中移除或释放该实例。 Examples of binding by the server status becomes discrete and prohibit locking hub network corresponding to the content data, the instance is removed or released from the hub network.

[0151] 图24示出将离散实例绑定到集线器网络的一个实现的流程图2400。 [0151] FIG. 24 shows a flowchart 2400 of one implementation of a discrete instance is bound to the hub network. 最初,服务器接收离散实例(块2405)。 Initially, the server receives the discrete instance (block 2405). 如上所述,离散实例可以各种形式在顺从性媒体上,诸如存储在顺从性存储媒体(例如光盘)上的电子文件,或存储在服务器存储器中的电子文件(例如,经网络连接通过下载接收的)。 As described above, the discrete instance can be in various forms on compliant media, such as electronic files stored on compliant storage media (e.g., CD-ROM) or electronic file stored in the server memory (e.g., received via a network connection to download of). 服务器也不产生离散实例的拷贝,因为服务器将不产生没绑定到集线器网络的离散实例的拷贝(虽然服务器可以产生离散实例的锁定内容数据的拷贝)。 The server does not produce a copy of discrete instance, because the server will not produce copies not bound to the hub network of discrete instance (although the server can generate discrete instances of locking a copy of content data).

[0152] 服务器接收来自用户的将离散实例绑定到集线器网络的请求(块2410)。 [0152] server receives a user request for a discrete instance is bound to the hub network (block 2410). 在一个实现中,服务器等待来自用户的请求。 In one implementation, the server waits for a request from the user. 在另一实现中,当服务器接收到离散实例时,服务器向用户发送询问,询问该服务器是否应将该离散实例绑定到集线器网络。 In another implementation, when the server receives the discrete instance, the server sends an inquiry to the user, asks whether the server should bind the discrete instance to the hub network.

[0153] 在服务器接收到绑定请求后,服务器禁止离散实例(块2415)。 [0153] After the server receives the bind request, the server to disable the discrete instance (block 2415). 通过禁止离散实例,顺从性设备不会呈现或播放该离散实例。 By disabling the discrete instance, compliance device does not appear or play the discrete instance. 在一个实现中,服务器通过禁止离散实例的许可证来禁止离散实例。 In one implementation, server licenses to disable the discrete instance by prohibiting discrete instance. 在另一实现中,服务器通过设置离散实例数据中的标记来禁止离散实例,以使顺从性设备不会呈现离散实例。 In another implementation, the discrete instance by providing the server data tags to disable the discrete instance, so that compliant device will not present the discrete instance. 在另一实现中,服务器通过用服务器专用的密钥对离散实例中的一些或全部加密来禁止离散实例。 In another implementation, the discrete instance on the server, some or all of the encryption server to disable the discrete instance by using a dedicated key. 在另一实现中,服务器通过将离散实例注册为用中央数据库或授权机构(例如,在呈现或播放内容数据之前设备与其协商)禁止的方式来禁止离散实例。 In another implementation, the server by using discrete instances registered as a database or central authority (for example, devices with their consultation before rendering or playing content data) a prohibition to prohibit discrete instances. 在另一实现中,离散实例仅被部分禁止,以使是禁止离散实例已绑定到的集线器网络的成员的设备可将离散实例作为子拷贝来呈现或播放。 In another implementation, the discrete instance is only partially disabled such that the device is a member of a discrete instance is bound to the prohibition of the hub network may be copied to the discrete instance as a sub rendered or played. 如果服务器不能禁止离散实例,则服务器不将离散实例绑定到集线器网络。 If the server can not disable the discrete instance, the server does not discrete instance is bound to the hub network.

[0154] 服务器从离散实例创建绑定实例(块2420)。 [0154] Server instances create a binding (block 2420) from the discrete instance. 服务器拷贝离散实例,包括拷贝锁定内容数据、包含许可授权信息的标题信息、解开锁定内容数据的密钥、离散许可证和撤消列表(如果存在)。 Server copy of discrete instance, includes a copy of locked content data, header information contains licensing information, unlock key content data, discrete and license revocation lists (if present). 服务器将锁定内容数据的拷贝存储为绑定实例的锁定内容数据的源版本。 The server stores a copy of locked content data for the bound instance of the source version content data locking. 服务器在适当时修改要成为根许可证的离散许可证,以管理绑定实例,而不是离散实例。 Server modify, where appropriate, to be discrete license root license to manage binding instance, instead of discrete instances. 备选地,服务器不拷贝离散许可证,而是使用离散许可证产生新的根许可证。 Alternatively, the server does not copy the discrete license, but the use of discrete license to generate new root license. 在另一实现中,服务器还(或而是)联系由许可授权信息指示的外部许可授权机构,以更新或产生根许可证。 In another implementation, the server also (or instead) external contact by the licensing authority licensing information indicates to update or produce root license. 在一个实现中,如果服务器不是服务器/客户机设备,并因此不呈现内容,则根许可证不存储关于服务器的呈现允许的许可信息。 In one implementation, if the server is not a server / client device, and therefore does not present the content, the root license is not stored on the presentation server license information allowed.

[0155] 在备选实现中,服务器通过删除离散实例中的一些或全部来禁止离散实例。 [0155] In an alternative implementation, the server or to prohibit all discrete instance to remove some discrete instance. 在此情况下,在删除离散实例之前,服务器首先建立离散实例的绑定实例。 In this case, before you delete a discrete instance, the server first establish binding instance discrete instance.

[0156] 在另一实现中,服务器将离散实例转换为绑定实例。 [0156] In another implementation, the server converts the discrete instance to bound instance. 在此情况下,服务器不产生离散实例的拷贝。 In this case, the server copies the discrete instance does not occur. 而服务器在适当时改变许可授权信息和许可证,以指示离散实例现在是绑定实例。 And the server changes when appropriate licensing information and license to indicate discrete instance is now binding instance.

[0157] 在一个实现中,在禁止离散实例并创建绑定实例之前,服务器确认允许该服务器绑定离散实例。 [0157] In one implementation, before disabling the discrete instance and create the binding instance, confirm that the server allows the server to bind the discrete instance. 服务器确认离散实例的许可证允许服务器绑定离散实例。 Confirm the license server allows the server to bind the discrete instance of discrete instances. 服务器还确认该服务器不在服务器撤销列表上。 The server also confirm that the server is not a server revocation list. 在另一实现中,服务器还确认在离散实例的锁定内容数据中有正确的水印。 In another implementation, the server also confirmed the right of the watermark in the locked content data in a discrete instance. 如果服务器没有成功确认允许绑定离散实例,则该服务器不绑定离散实例。 If the server does not allow binding a discrete instance of successful confirmation, the server does not bind the discrete instance.

[0158] 在一个实现中,服务器记录广播信息,并将其存储为绑定内容并建立根。 [0158] In one implementation, the server records the broadcast information, and stores it as bound content and establishes the root. 服务器自动创建根许可证。 Server automatically creates the root license. 在备选实现中,服务器使用广播中的信息来定义根许可证,或使用广播信息中的许可授权信息来联系外部许可授权机构,以获得构建根许可证的许可证。 In an alternative implementation, the server uses information broadcast to define the root license, authorization or license information broadcast information to contact external licensing authority, in order to obtain a license to build the root license. 在另一实现中,服务器将来自广播的内容记录为离散实例。 In another implementation, the server will record the broadcast content from a discrete instance. 在一个实现中,广播信息包括密钥、许可授权信息和构建离散拷贝的许可信息。 In one implementation, the broadcast information includes the key, licensing authority information and licensing information to build the discrete copy. 在另一实例中,服务器记录广播信息,并将其存储为绑定内容并建立根。 In another example, the server records the broadcast information, and stores it as bound content and establishes the root. 服务器使用广播信息中的许可授权信息来联系外部许可授权机构,以获得构建根拷贝的许可证。 The server uses information broadcast licensing information to contact an external licensing authority, in order to obtain a copy of the license to build root. 在一个实现中,服务器根据广播提供的任何拷贝控制信息对广播信息的媒体内容加密。 In one implementation, the server encrypts the media content of the control information of broadcast information according to any copy of the broadcast provider.

[0159]图25示出了从集线器网络中释放内容拷贝、产生内容离散(“离散性(discretification)")的一个实现的流程图2500。 [0159] FIG. 25 shows a copy of the content is released from the hub network, the discrete content is generated ( "discrete (discretification)") of a flowchart 2500 of one implementation. 最初,绑定实例存储在服务器上和存储内容子拷贝版本的任何客户机上。 Initially, the bindings on the server and store content on the sub-copy version of any client instance storage.

[0160] 服务器从用户那接收从集线器网络释放绑定实例并创建离散实例的请求(块2505)。 [0160] Examples of binding server that receives from the user released from the hub network and create a discrete instance of the request (block 2505). 在一个实现中,服务器等待来自用户的请求。 In one implementation, the server waits for a request from the user. 在另一实现中,当服务器接收到不可用于绑定实例的操作的请求时,诸如将绑定实例移出集线器网络,服务器向用户发送询问。 In another implementation, when the server receives the request operation is not available for binding instance, such as a network hub out of the binding instance, the server sends a query to the user. 在此情况下,询问服务器是否应该从集线器网络中释放绑定实例并创建离散实例。 In this case, ask the server whether it should release the binding instance from the hub network and create a discrete instance. [0161] 在服务器接收到离散请求之后,该服务器使集线器网络的客户机禁止相应绑定实例的子拷贝版本(块2515)。 [0161] After the server receives the discrete request, the server that the client network hub disable the corresponding sub-copy versions of bound instances (block 2515). 服务器将禁止请求发送到集线器网络的每个成员,指定哪个绑定实例子拷贝版本要被禁止。 The server will prohibit request is sent to each member of the hub network, specify which bind instance sub-copy version to be prohibited. 备选地,服务器将禁止请求发送到具有绑定实例子拷贝版本的成员(例如,通过发送到客户机的许可证所指示的)。 Alternatively, the server request to prohibit the sub-copy version has a binding members instances (e.g., by sending the license to the client indicated). 接收到禁止请求的客户机禁止对应于绑定实例的所有子拷贝版本。 Prohibition request is received corresponding to the client binding instance prohibit all sub-copy version. 通过禁止子拷贝版本,顺从性设备不会呈现或播放禁止的子拷贝版本。 By prohibiting child copy version, compliant device does not appear or play prohibit sub-copy version. 在一个实现中,客户机通过禁止子拷贝版本的许可证来禁止该子拷贝版本。 In one implementation, the client to disable the sub-copy version of the license is prohibited by the sub-copy version. 在另一实现中,客户机删除要禁止的子拷贝版本。 In another implementation, the client deletes the sub-copy version to be disabled. 在另一实现中,客户机通过在子拷贝版本的数据中设置标记来禁止该子拷贝版本,以使顺从性设备不会呈现该子拷贝版本。 In another implementation, the client by setting a flag in the sub-copy version of the data to disable sub-copy version, so that the compliant device will not present the sub-copy version. 在另一实现中,客户机通过用客户机专用的密钥将子拷贝版本加密来禁止该子拷贝版本。 In another implementation, a client via the client's private key encryption sub-copy version disables the sub-copy version. 在另一实现中,客户机通过用中央数据库或授权机构(例如,在呈现或播放子拷贝版本之前与其协商)将绑定实例注册为被禁止的方式来禁止子拷贝版本。 In another implementation, the client by using a central database or authority (eg, in consultation with their child before rendering or play copy version) will be registered as a way of binding instance prohibited to prohibit sub-copy version. 如果这时客户机从集线器网络断开,则当客户机设备重新连接到集线器网络时,服务器产生禁止相应子拷贝版本的请求。 If at this time the client is disconnected from the hub network, when the client device reconnects to the hub network, the server generates a request to disable the corresponding sub-copy version.

[0162] 在服务器禁止子拷贝版本之后,该服务器禁止源版本(块2515)。 [0162] After the sub-copy version of the server is prohibited, the prohibition source version server (block 2515). 通过禁止源版本,顺从性设备不会呈现或播放该源版本。 By disabling the source version, the compliant device does not appear or play the source version. 服务器禁止源版本类似于服务器禁止离散实例,或客户机禁止子拷贝版本,诸如通过禁止绑定实例的根许可证。 Server version is similar to the source is prohibited ban discrete server instance, or client prohibit sub-copy version, such as root prohibited by binding instance license.

[0163] 服务器从绑定实例产生离散实例(块2520)。 [0163] The server generates a discrete instance from the bound instance (block 2520). 服务器拷贝绑定实例,包括拷贝锁定内容数据的源版本、包含许可授权信息的标题信息、解开锁定内容数据的密钥、根许可证和撤消列表(如果存在)。 Server copy binding instance, includes a copy of the source version of locked content data, including header information licensing information, unlock key content data, and the root license revocation lists (if present). 服务器将离散实例存储在内部存储器或外部顺从性媒体上(例如,根据来自用户的离散请求)。 The server stores the discrete instance on internal memory or external compliant media (e.g., according to the discrete request from the user). 服务器在适当时修改离散实例(而非绑定实例)的根许可证。 Server modify discrete instances when appropriate (rather than binding instance) the root license. 备选地,服务器不拷贝根许可证,而是使用根许可证生成新的离散许可证。 Alternatively, the server does not copy the root license, the root license generation but a new discrete license. 在另一实现中,服务器还(或而是)联系由许可授权信息指示的外部许可授权机构,以更新或生成离散许可证。 In another implementation, the server also (or instead) external contact by the licensing authority licensing information indicates to update or generate discrete license.

[0164] 在一个实现中,在外部顺从性媒体上创建离散实例之前,服务器确认该顺从性媒体可用于存储新的离散实例。 Before [0164] In one implementation, creates a discrete instance on external compliant media, the server confirms that compliant media can be used to store the new discrete instance. 如果顺从性媒体不可用,则服务器可在内部存储器上创建离散实例,或者服务器可使用批准的记录技术(例如,由根许可证或由集线器网络的配置批准的)来创建非顺从性拷贝。 If compliant media is not available, the server can create a discrete instance on internal storage or the server (e.g., approved by the root license or by the configuration of the hub network) to create a non-compliant copy using approved recording technology. 在一个实现中,批准的记录技术的例子包括4C或D-VHS。 In one implementation, examples of approved recording technologies include 4C or D-VHS. 一旦服务器已经创建了非顺从性拷贝,该非顺从性拷贝将不能再被绑定,并且禁止的子拷贝将不能被激活(在没购买新许可证的情况下)。 Once the server has created a non-compliant copy, the copy of the non-compliance will no longer be bound and prohibited child copy will not be activated (in the case did not buy new licenses). 相应地,在创建非顺从性拷贝之前,服务器请求确认。 Accordingly, before creating the non-compliant copy, the server requests confirmation. 如果外部顺从性媒体不可用,并且批准的记录技术不可用,则服务器不会在外部存储器上产生离散实例。 If external compliant media is not available and approved recording technology is not available, the server does not generate discrete instance on external storage. 在一个实现中,用户可请求从离散实例创建非顺从性拷贝,而不管顺从性媒体的存在(虽然仍然需要批准的记录技术)。 In one implementation, the user can request a copy from a discrete non-compliance instances, regardless of the existence of compliance media (although still need to approve the recording technology).

[0165] 在另一实现中,服务器将绑定实例转换为离散实例。 [0165] In another implementation, the server converts the bound instance to a discrete instance. 在此情况下,服务器不需要产生绑定实例的拷贝。 In this case, the server does not need to produce a copy of the bound instance. 而是,服务器在适当时改变许可授权信息和许可证,以指示绑定实例现在是离散实例。 Instead, the server change licensing information and license, where appropriate, to indicate binding instance are now discrete instances.

[0166] 在另一实现中,存储客户机设备还可将绑定实例的状态变为离散。 [0166] In another implementation, a storage client device can also bind a discrete state of the instance changes. 在此情况下,客户机设备通知服务器,并且服务器禁止源版本和所有其余子拷贝版本(例如,通过将禁止请求发送到其它客户机)。 In this case, the client device informs the server, and the server to disable the source versions and all remaining sub-copy version (e.g., by the prohibition request is sent to the other clients). 在备选实现中,存储客户机设备请求集线器网络的所有成员设备禁止内容的子拷贝版本(其受存储客户机设备的许可证的控制)。 In an alternative implementation, the storage client device requests the network hub sub-copy version to all members of the equipment is prohibited contents (which is controlled by the storage device of the client licenses). 在一个实现中,如果客户机设备存储子拷贝版本或存储其它锁定内容数据,则该客户机设备包括将绑定实例的状态变为离散的功能性。 In one implementation, if a client device stores sub-copy versions or stores other locked content data, the client device includes binding instance state becomes discrete functionality.

[0167] 在一个实现中,服务器不会释放在许可信息中包含限制时间的使用规则的绑定实例。 [0167] In one implementation, the server does not release the binding instance contains rules limit use of time in the license information. 在此情况下,如果服务器接收到将绑定实例变为离散实例的请求,则该服务器拒绝该请求,并且具有相应子拷贝版本的绑定实例保持激活。 In this case, if the server receives a request to bind a discrete instance becomes instance, the server rejects the request, and has a sub-copy versions of the corresponding bound instance remain active.

[0168] 在一个实现中,服务器确认在禁止绑定实例并创建离散实例之前允许该服务器释放该绑定实例。 [0168] In one implementation, the server allows the server to confirm the release of the binding instance before the ban binding instance and create a discrete instance. 服务器确认绑定实例的根许可证允许该服务器释放绑定实例。 Confirm root server license binding instance allows the server to release the binding instance. 服务器还确认该服务器不在服务器的撤销列表上。 The server also confirmed the revocation of the server is not on the list server. 如果服务器没有成功确认允许释放绑定实例,则该服务器不释放该绑定实例。 If the server does not allow the release to confirm a successful binding instance, the server does not release the binding instance.

[0169] 内容许可证管理 [0169] Content License Management

[0170] 服务器管理绑定到该服务器的集线器网络的绑定实例的子拷贝版本的许可证。 [0170] server management network hub is bound to the binding instance of the server sub-copy version of the license. 如上所述,当服务器将内容实例绑定到集线器网络时,该服务器创建具有根许可证的绑定实例。 As mentioned above, when the content server instance is bound to the hub network, the server creates binding instance has a root license. 具有绑定实例的根许可证的服务器是集线器网络中绑定实例的本地许可授权机构,并且该服务器使用该根许可证来控制集线器网络中绑定实例的所有子拷贝版本的许可。 Root license server having a local binding instance license authority binding instance hub network and the server uses the root license to control the licensing of all the sub binding instance copy version of the hub network.

[0171] 顺从性设备使用许可证来用内容实例的锁定内容数据,诸如呈现、拷贝或移动锁定内容数据。 [0171] compliant device uses a license to use locked content data of instances of content, such as rendering, copying or moving content data locking. 在一个实现中,许可证指示为特定锁定内容数据定义的允许集。 In one implementation, a license indicating the locking of the content data set is defined to allow specific. 许可证允许根据类型(例如离散实例、绑定实例)指示呈现、拷贝和移动锁定内容数据的允许。 The license allows the type (e.g., discrete instance, bound instance) indicative of presentation, copying and moving of content data allowed to lock. 许可证还可指示允许的条件,诸如基于时间(例如,租用的时限)、地理(例如区代码)、用户身份(例如密码)。 Licenses may also indicate permissible conditions, such as time (for example, leased time limit) based on geography (for example, the area code), user identity (such as a password). 通过与许可授权机构的相互作用(例如,租用销售量的附加付费),可改变或更新许可证。 By interacting with the licensing authority (for example, sales of leased additional fee), can be changed or updated licenses. 在没有当前有效且激活的许可证的情况下,顺从性设备不会呈现锁定内容数据。 In the absence of an effective and active current license, the compliance device does not appear locked content data. 当顺从性设备首先使用锁定内容数据时,该顺从性设备请求新许可证,或确认锁定内容数据的许可证。 When using the first locking device compliant content data, the compliant device requests a new license or license confirmation locked content data. 服务器只将许可证提供给集线器网络本地环境中的服务器集线器网络的成员客户机。 The license server is only available to hub network in the local environment of the hub network server a member of the client.

[0172] 在另一实现中,服务器使用中间设备(例如,另一客户机设备)将许可证提供给断开的和/或在集线器网络本地环境之外的成员客户机。 [0172] In another implementation, the server uses an intermediate device (e.g., another client device) will be provided to permit disconnection and / or members of the hub network client outside the local environment. 中间设备用作许可证的“导管”(类似于如上所述将远程设备添加为成员)。 Intermediary Device as license "duct" (similar to adding a remote device as described above is a member). 服务器和客户机不连接,或是该客户机不在服务器的本地环境中。 Server and client are not connected, or is not in the local environment of the client server. 中间设备连接到服务器和客户机(例如,直接、间接或在不同时间,诸如当该中间设备是在服务器和客户机之间移动的便携式设备时)。 The intermediate device is connected to the server and client (e.g., directly, indirectly, or at different times, such as when the intermediary device is a portable device moving between the server and the client time). 中间设备在服务器和客户机之间传递信息,并且最终将许可证从服务器传到客户机(如果服务器将许可证授予客户机的话)。 Intermediate device to transmit information between the server and client, and eventually spread to the license server from the client (if the server grants the license if a client).

[0173] 在一个实现中,如果传送时两个设备都在同一本地环境中,则客户机设备可将其许可证扩展到同一集线器网络的另一成员客户机。 [0173] In one implementation, if the two devices are transmitted in the same local environment, the client device can be extended to the same hub network license of another member of the client. 扩展的许可证与扩展客户机设备所拥有的许可证相同(或前者比后者更具限制性),因此扩展客户机不会扩大许可证的允许。 The same license extension and expansion of the client device owned license (or the former than the latter more restrictive), thus expanding the client does not expand the license allows. 接收客户机在收到许可证时刷新许可证。 Receiving client refresh licenses on receipt of the license. 扩展之后,扩展客户机和接收客户机都有许可证。 After the expansion, the expansion and the client receives a client has a license.

[0174] 许可证刷新 [0174] refresh license

[0175] 绑定实例的子拷贝版本的许可证具有截止周期。 Sub-copy version of the [0175] binding instance has a license off period. 当客户机接收到许可证时,该客户机根据许可证的截止周期和客户机安全时钟的当前时间来设置截止时间。 When the client receives the license, the client sets the deadline for the current time and the off period of the license client's secure clock. 例如,对于截止周期为15天的许可证,客户机会将截止时间设为从接收到许可证起的15天。 For example, for a period of 15 days as of the license, the client receives from the deadline set to the license from 15 days. 当时钟指示已达到截止时间时,许可证到期。 When the clock indicating the deadline has been reached, the license expires. 客户机通过联系存储子拷贝版本根许可证的服务器来周期性地刷新客户机存储的每个子拷贝版本的许可证。 The client version root license copy by contacting the storage sub-server periodically refresh the client stores each sub-copy version of the license. 当许可证被刷新时,客户机根据刷新的许可证的截止周期来重新设置截止时间。 When the license is refreshed, the client to re-set the deadline according to the cutoff period to refresh the licenses. 在许可证没被刷新时,截止时间保持不变,并且因此达到截止时间之前的截止周期中的剩余时间继续减少。 When the license has not been refreshed, the deadline remains the same, and therefore the time to reach the remaining cut-off period before the deadline continued to decline. 当客户机重新连接到集线器网络时,客户机还刷新对应于该集线器网络的子拷贝版本的所有其许可证。 When the client is reconnected to the hub network, the client also refresh corresponds to the sub-copy version of the hub network for all of its licenses.

[0176] 图26示出了更新和刷新许可证的一个实现的流程图2600。 [0176] FIG. 26 illustrates one implementation of updating and refreshing a license of a flowchart 2600. 最初,客户机存储绑定实例的锁定内容数据的子拷贝版本。 Initially, the client binding instance storage sub-copy version of locked content data. 子拷贝版本的许可证绑定到特定集线器网络,并且因此该集线器网络的服务器管理对应于客户机存储的子拷贝版本的绑定实例。 The sub-copy version of the license bound to a specific network hub, the hub and thus the network management servers corresponding to the bound instance sub-copy version stored in the client. 当客户机接收到子拷贝版本的许可证时,该客户机根据截止周期和客户机时钟的时间来设置许可证的截止时间。 When a client receives a license to a sub-copy version, the client set the off time off period of time according to the license and the client clock. 客户机的时钟是安全时钟,并以规则速率前进。 The client's clock is the clock security, and rule-rate advance. 如果客户机没接收到具有子拷贝的激活许可证,则客户机在接收到子拷贝时请求新的或刷新的许可证。 New or refreshed license request if the client has not received a copy of the sub-license activation, the client receives a copy of the child.

[0177] 客户机请求来自服务器的刷新许可证(块2605)。 [0177] Refresh client requests a license from the server (block 2605). 客户机将刷新请求发送到子拷贝版本的绑定实例绑定到的集线器网络的服务器。 Client request to refresh the sub-copy versions of bound instances bound to the hub network server. 客户机周期性地将刷新请求发送到服务器,诸如每分钟或每小时一次。 The client will periodically refresh request sent to the server, such as once every minute or hour. 在一个实现中,服务器或用户可调整客户机请求刷新许可证的频率。 In one implementation, the server or client user may adjust the frequency of the refresh request a license. 在一个实现中,在请求刷新的许可证之前,或除请求刷新的许可证之外,客户机请求来自服务器的时间同步。 In one implementation, prior to refresh the license request, or in addition to refresh the license request, the client requests from the server time synchronization.

[0178] 服务器接收请求,并确认客户机被正确配置为接收刷新许可证(块2610)。 [0178] The server receives the request and confirms the client is properly configured to receive a refreshed license (block 2610). 服务器确认客户机连接了,并在集线器网络的本地环境中(例如,通过强制回应客户机)。 Server acknowledges the client connection and the local environment of the hub network (for example, by pinging the client). 如果客户机没有连接,或不在本地环境中,则服务器不发送刷新许可证。 If the client is not connected, or not on the local environment, the server does not send a refreshed license. 服务器还确认客户机具有正确的安全软件和数据(例如密钥)。 The server also confirm that the client has the proper security software and data (such as keys). 如果客户机没有正确的安全软件和数据,则服务器将包括更新软件和数据的安全更新发送到客户机。 If the client does not have the proper security software and data, the server update will include updated security software and data is sent to the client. 如果服务器不能将安全更新发送到客户机,则服务器不将刷新许可证发送给客户机。 If the server can not send security updates to the client, the server does not refresh the license sent to the client. 如果服务器没接收到刷新请求,则服务器不将刷新许可证发送到客户机。 If the server does not receive a refresh request, the server does not refresh the license sent to the client.

[0179] 在确认客户机之后,服务器确认客户机的许可证(块2615)。 [0179] After confirming the client, the license server validates the client (block 2615). 服务器确认该客户机不在服务器的撤消列表上。 Server confirms the revocation list is not in the client server. 在一个实现中,在服务器将新许可证发送到客户机之前,该服务器和客户机还交换和更新撤消列表。 In one implementation, before the server will send a new license to the client, the server and client exchanged and updated revocation list. 如果客户机在服务器的撤消列表上,则服务器不发送刷新许可证。 If the client is on the revocation list server, the server does not send a refreshed license. 服务器通过检查根许可证来确定许可证是否仍可用于该客户机。 Server is determined by examining the root license if the license is still available for the client. 如果根许可证指示许可证可用于该客户机,则服务器将刷新许可证发送到该客户机。 If the root license indicates the license available to the client, the server will refresh the license is sent to the client. 刷新许可证不一定与存储在客户机中的许可证相同。 Refresh license not necessarily the same license stored on the client machine. 服务器可通过将不同的许可证作为刷新许可证发送来更新客户机许可证的方面。 Server by the different aspects of the license as a license to send refresh to update the client licenses. 例如,在一个实现中,服务器周期性地请求来自外部许可授权机构的许可证更新,并相应地更新根许可证。 For example, in one implementation, the server periodically requests license updates from an external licensing authority and updates the root license. 在另一实现中,根许可证根据改变标准(诸如时间、付费或客户机状态)来指示不同的许可允许。 In another implementation, the root license according to a change criterion (such as time, payment, or client status) to indicate different license permits. 如下所述,在一个实现中,在创建新的子拷贝版本时,该新的子拷贝版本具有禁止许可证,并需要对新设备特定的新许可证。 As described below, in one implementation, when creating a new sub-copy version, the new sub-copy version has prohibited license and needs a new license specific to the new device. 响应对新子拷贝版本的第一刷新请求,服务器使用根许可证创建新许可证。 Response to the first refresh request for a new sub-copy version, the server uses the root license to create a new license.

[0180] 如果根许可证指示许可证不可用于客户机,则服务器不将刷新许可证发送给该客户机。 [0180] If the root license indicates the license is available for the client, the server does not send a refreshed license to the client. 如果根许可证指示由于环境的变化(例如租用的时限已到期,或还未付订金)内容的许可证不再有效,则该许可证不可用。 If the root license indication due to changes in the environment (such as leased the time limit has expired, or has not paid the deposit) content is no longer valid license, the license is not available. 在一个实现中,服务器还与外部许可授权机构协商一些或全部刷新请求。 In one implementation, the server is also in consultation with the licensing authority outside of some or all of the refresh request. 在一个实现中,服务器将解释不发送刷新许可证的原因的消息发送给客户机。 In one implementation, the server will explain the reasons for not sending a message to refresh the license to the client.

[0181] 在另一实现中,服务器不发送刷新许可证,而是发送指示是否能够刷新许可证和对许可证任何改变的消息或标记。 [0181] In another implementation, the server does not send a refresh the license, but be able to refresh the license indicating whether the transmission message and any changes to the license or labeled. [0182] 客户机确定服务器是否发送刷新许可证(块2620)。 [0182] The server sends the client to determine whether to refresh the license (Block 2620). 如果客户机从服务器断开,则服务器不会响应刷新请求,且因此该客户机不会接收刷新许可证。 If the client is disconnected from the server, the server does not respond to the refresh request and so the client does not receive a refreshed license. 在另一实现中,客户机首先检查来自服务器的任何响应。 In another implementation, the client first checks for any response from the server. 在另一实现中,如果客户机从集线器网络断开,则客户机不发送刷新请求,并继续,就好像没接收到刷新许可证一样。 In another implementation, if the client is disconnected from the hub network, the client does not send a refresh request and continue, if not received the same refresh license. 如果服务器不可用,或被禁止了,则该服务器不会发送刷新许可证。 If the server is unavailable or prohibited, and the server does not send a refreshed license. 如上所述,如果服务器没有成功确认客户机或许可证,则不允许客户机接收刷新许可证,并且服务器不发送刷新许可证。 As mentioned above, if the server does not successfully confirm that the client or license, you can not refresh the client receives the license, and the server does not send a refreshed license.

[0183] 如果客户机接收到刷新许可证,则客户机刷新许可证(块2625)。 [0183] If the client receives the refreshed license, the client refreshes the license (block 2625). 客户机用刷新许可证代替存储的许可证。 Instead of storing client refresh license with a license. 将截止时间重新设回截止周期的最大值。 The deadline set back the maximum cut-off period.

[0184] 如果客户机没有接收到刷新许可证,则该客户机确定许可证是否已经到期(块2630)。 [0184] If the client does not receive a refreshed license, the client determines whether the license has expired (block 2630). 在已过截止周期还没接收到刷新许可证的情况下,许可证到期。 In the case of an off period has passed yet received refresh the license, the license expires. 当客户时钟指示已达到截止时间时,许可证到期。 When the client clock indicating the deadline has been reached, the license expires. 在其它实现中,可用不同的机制来确定截止周期何时到期,诸如减量定时器。 In other implementations, different mechanisms can be used to determine when the cutoff period expires, such as a decrementing timer.

[0185] 如果许可证已到期,则客户机禁止该许可证(块2635)。 [0185] If the license has expired, the client disables the license (block 2635). 客户机禁止许可证,以使该客户机和其它顺从性设备不会呈现那个子拷贝版本。 The client license is prohibited, so that the client and other compliant devices that are not rendered sub-copy version. 在一个实现中,客户机以另一种方式禁止子拷贝版本,诸如加密该子拷贝版本或删除该子拷贝版本。 In one implementation, the client is prohibited sub-copy version in another way, such as encryption or delete the sub-copy version of the sub-copy version.

[0186] 当用于请求刷新许可证的下一周期出现时,客户机返回块2605。 [0186] When a request for a license next refresh cycle occurs, the client returns to block 2605. 在一个实现中,客户机可与请求刷新的许可证无关地确定许可证已到期(例如,当截止时间在请求刷新许可证之间时)。 In one implementation, the client may request to refresh a license has expired independently determine whether the license (e.g., when the off time between requests refreshed license).

[0187] 在一个实现中,如果客户机没有从服务器接收到刷新许可证,则该客户机从外部许可证授权机构请求刷新的或新的许可证。 [0187] In one implementation, if the client is not received from the server to refresh the license, the client requests a refreshed or new license from an external license authority. 如上所述,服务器是由子拷贝版本标题信息中的许可授权信息定义的本地许可授权机构。 As mentioned above, the server is a local authority license by the licensing sub-copy version of the header information in the definition information. 许可授权信息还可指示外部许可授权机构,诸如通过网络(例如互联网)连接到客户机的中央服务器。 Licensing information may also indicate an external licensing authority, such as a central server connected to a client through a network (e.g. the Internet). 在一个实现中,当服务器不可用时,或当客户机不是服务器的集线器网络成员且需要新许可证时,该客户机请求来自外部授权机构的许可证。 In one implementation, when the server is not available, or when the hub network client is not a member of a server and requires a new license, the client requests a license from an external authority. 在另一实现中,许可授权信息指示授权机构的级别(例如,本地的、区域的、国家的或绝对的)。 In another implementation, the licensing authority level information indicating (eg, local, regional, national or absolute).

[0188] 图27-29示出从集线器网络断开设备以及截止周期操作的例子。 [0188] Figures 27-29 illustrate an example of a cut-off period of operation of the device is disconnected from the hub network. [0189] 在图27中,两个媒体网络环境2700和2750处于不同的本地环境中。 [0189] In Figure 27, two media network environments 2700 and 2750 are in different local environments. 本地环境是相对于服务器的位置定义的(紧密相邻的两个服务器被视为定义基本同时扩张的本地环境)。 The local environment is relative to the location of the server defined (in close proximity to two servers at the same time is considered to define the basic expansion of the local environment). 虚线表示本地环境之间的中断。 The dashed line represents the break between the local environment. 第一媒体网络环境2700包括4个设备:连接到终端设备2710 (用于呈现内容)的服务器/客户机设备2705、服务器设备2715和客户机设备2720。 The first media network environment 2700 includes four devices: a server connected to the terminal device 2710 (for presenting content) / client device 2705, the server device 2715 and the client device 2720. 服务器/客户机设备2705是集线器网络HNl的服务器(由“HN1*”标号指示)。 The server / client device 2705 is the server of the hub network HNl (by the "HN1 *" label indicated). 月艮务器/客户机设备2705和客户机设备2720是集线器网络HNl中的客户机(由“HN1”标号指示)。 Month that works to control / client device 2705 and the device 2720 is a client in the hub network HNl client (the "HN1" label indicated). 服务器设备2715是集线器网络HN2的服务器(由“HN2*”标号指示)。 The server device 2715 is the server of the hub network HN2 (by the "HN2 *" label indicated). 服务器/客户机设备2705和客户机设备2720是集线器网络HN2中的客户机(由“HN2”标号指示)。 The server / client device 2705 and the client device 2720 are clients in the hub network HN2 (manufactured by "HN2" label indicated).

[0190] 两个内容条目A和B绑定到集线器网络HN1。 [0190] two content items A and B are bound to the hub network HN1. 服务器/客户机设备2705存储两个内容条目A和B中每一个的源版本并管理根职责,由“A”和“B”标号指示。 The server / client device 2705 stores two content items A and B of each of the source version and manages root responsibility, indicated by "A" and "B" labels. 客户机设备2720存储两个内容条目A和B中每一个的子拷贝版本(由“a”和“b”标号指示)。 The client device 2720 stores two content items A and B of each of the sub-copy version (indicated by "a" and "b" numbered).

[0191] 一个内容条目X绑定到集线器网络HN2。 [0191] a content item X is bound to the hub network HN2. 服务器设备2715存储内容条目X的源版本并管理根职责,由“X”标号指示。 Source version of the server device 2715 to store and manage content items X root duties by "X" label instructions. 服务器/客户机设备2705和客户机设备2720中的每一个都存储内容条目X的子拷贝版本(由“X”标号指示)。 The server / client device 2705 and the client device 2720 is stored in each of the sub-copy version of the content item X (by "X" numerals). 服务器设备2715还存储内容条目Y的离散实例(由“Γ标号指示)。 Examples of discrete server device 2715 also stores content items Y (indicated by "Γ numerals).

[0192] 第二媒体网络环境2750包括一个设备:服务器/客户机设备2755。 [0192] The second media network environment 2750 includes one device: a server / client device 2755. 服务器/客户机设备2755是集线器网络HN3的服务器(由“HN3*”标号指示)。 The server / client device 2755 is the server of the hub network HN3 (from the "HN3 *" numerals). 服务器/客户机设备2755是集线器网络HN3中的客户机(由“HN3”标号指示)。 The server / client device 2755 is the hub network HN3 in the client (the "HN3" label indicated).

[0193] 一个内容条目M绑定到集线器网络HN3。 [0193] a content item M is bound to the hub network HN3. 服务器/客户机设备2755存储内容条目M的源版本并管理根职责,由“M”标号指示。 Server / client device 2755 version of the source storage and management of content items M root duties by "M" label instructions.

[0194] 在图28中,服务器/客户机设备2705移动到第二媒体网络环境2750,并作为客户机成为集线器网络HN3的成员(由“HN3”标号指示)。 [0194] In FIG. 28, the server / client device 2705 moves to the second media network environment 2750 and becomes a member as a client of the hub network HN3 (from the "HN3" label indicated). 服务器/客户机设备2705仍是集线器网络HNl和HN2的客户机(由“HN1”和“HN2”标号指示)。 Server / client device 2705 is still the hub and network HNl HN2 client (by the "HN1" and "HN2" label instructions). 服务器/客户机设备2705接收内容条目M的子拷贝版本(由“m”标号指示)。 The server / client device sub-copy version 2705 receives the content item M (indicated by "m" numerals). 服务器/客户机设备2755作为客户机加入集线器网络HNl (由“HN1 ”标号指示)。 The server / client device 2755 Network Hub HNL added (by the "HN1" label indicated) as a client. 服务器/客户机设备2755接收内容条目A和B中每一个的子拷贝版本(由“a”和“b”标号指示)。 The server / client device 2755 receives the content items A and B of each of the sub-copy version (indicated by "a" and "b" numbered).

[0195] 通过移动到第二媒体网络环境2750,服务器/客户机2705已将集线器网络HNl的本地环境带到第二媒体网络环境2750。 [0195] By moving to the second media network environment 2750, the server / client 2705 has the local environment of the hub network HNl to the second media network environment 2750. 结果,客户机设备2720不再处于集线器网络HNl的本地环境中,并因此客户机设备2720从集线器网络HNl断开。 As a result, the client device 2720 is no longer in the local environment of the hub network HNL, and so the client device 2720 is disconnected from the hub network HNl. 由于断开了,客户机设备2720不能刷新内容条目A和B的子拷贝版本a和b的许可证,并且因此不会重新设置子拷贝版本a和b的截止时间(由“a_15”和“b_15”标号指示)。 Since the disconnected client device 2720 can not refresh the license content items A and B sub-copy versions a and b, and therefore does not reset the sub-copy versions a and b of the cut-off time (the "a_15" and "b_15 "label instructions).

[0196] 此外,当服务器/客户机设备2705离开媒体网络环境2700时,由于服务器/客户机设备2705已离开了集线器网络HN2的本地环境,因此服务器/客户机设备2705变为从集线器网络HN2断开。 [0196] Further, when the server / client device 2705 leaving the media network environment 2700, since the server / client device 2705 has left the local environment of the hub network HN2, the server / client device 2705 becomes off from the hub network HN2 open. 由于断开了,服务器/客户机设备2705不能刷新内容条目X的子拷贝版本X的许可证,并因此不会重新设置子拷贝版本X的截止时间(由“X—15”标号指示)。 Due to disconnect, the server / client device 2705 can not refresh the contents of the sub-license entry X X version of the copy, and therefore does not reset the sub-copy version X of the deadline (the "X-15" label instructions). 然而,服务器/客户机设备2705已成为集线器网络HN3的成员,并且集线器网络HN3处于与集线器网络HN2不同的本地环境中。 However, the server / client device 2705 has become a member of the hub network HN3, and network hubs and hub network HN3 in HN2 different local environments. 如上所述,在一个实现中,当跨越设备是处于不同本地环境中的两个集线器网络的成员时,客户机将只呈现来自设备最近连接到的集线器网络(在本例中是集线器网络HN3 (以及集线器网络HN1,因为服务器/客户机设备是集线器网络HNl的服务器))的子拷贝版本。 As described above, in one implementation, when a spanning device is a member of a different local environment at the two hub network, the client will only present from the hub network HN3 device newly connected to a network hub (in the present embodiment ( and a hub network HN1, because the server / client device is the hub of a network HNl server)) sub-copy version. 相应地,暂时禁止内容条目X的子拷贝版本X,直到服务器/客户机设备2705再次连接到集线器网络HN2为止(由“*_15”标号指示(删除线))。 Accordingly, the sub-copy version temporarily disabled content item X X until the server / client device 2705 is connected again to the hub network HN2 up (by the "* _15" numerals (strikethrough)). 在备选实现中,跨越设备客户机没有暂时禁止来自远程集线器网络的子拷贝版本,并继续监控没被刷新的子拷贝版本的截止周期,如上所述。 In alternative implementations, the client device across a temporary ban no sub-copy version from a remote hub of the network, and continue to monitor the child has not been refreshed copy version off period, as described above.

[0197] 在图29中,服务器/客户机设备2705已返回到第一媒体网络环境2700,并连接到服务器设备2715和客户机设备2720,重新连接到集线器网络HN2。 [0197] In FIG. 29, the server / client device 2705 has returned to the first media network environment 2700, and 2715 are connected to a server device and a client device 2720, reconnecting to the hub network HN2. 结果,客户机/服务器设备2705可刷新子拷贝版本X的许可证,并且客户机设备2720可刷新子拷贝版本a和b的许可证(由上标的移除指示)。 As a result, the client / server device 2705 can refresh the licenses of sub-copy version X, and the client device 2720 can refresh sub-copy versions a and b of the license (indicated by the removal on the subject).

[0198] 通过服务器/客户机设备2705离开第二媒体网络环境2750,服务器/客户机设备2705从集线器网络HN3断开,并且服务器/客户机设备2755从集线器网络HNl断开。 [0198] 2750, the server / client device 2705 is disconnected the server / client device 2705 leaving the second media network environment through a network of HN3 from the hub, and the server / client device 2755 is disconnected from the hub network HNl. 结果,服务器/客户机设备2705不能刷新子拷贝版本m的许可证,因此截止时间没被重新设置,并且子拷贝版本m被暂时禁止了(由标号指示)。 As a result, the server / client device 2705 can not refresh the licenses of sub-copy version m, so the deadline has not been reset, and the sub-copy version m is temporarily disabled (indicated by a reference numeral). 服务器/客户机设备2755不能刷新子拷贝版本a和b的许可证,因此没重新设置截止时间(由“a_15”和“b_15”标号指示)O The server / client device 2755 can not refresh sub-copy versions a and b of the license, so no deadline reset (by the "a_15" and "b_15" numerals) O

[0199] 内容旱现 [0199] Content drought now

[0200] 客户机设备呈现或播放内容。 [0200] The client device rendering or playing content. 某些客户机设备包括集成呈现部件,并直接呈现内容数据。 Some client devices include integrated presentation components and present content data directly. 某些客户机设备通过连接的设备(例如终端设备)呈现内容数据。 Some client devices present content data through a device (e.g., a terminal device) is connected. 某些客户机以任一种或两种方式呈现内容数据。 Some clients in either one or two ways to present content data. 存储客户机设备呈现存储在客户机设备上的子拷贝中的内容数据,或从服务器流出的内容数据中的内容数据。 Content content data storage client device presents content data stored in a sub-copy on the client device or server from flowing in. 非存储客户机设备呈现从服务器流出的内容数据。 Non-storage client device rendering the content data from the server outflow. 返回图17,从服务器设备1715到非存储客户机1725的虚线指示将内容数据从服务器设备1715流到非存储客户机1725。 Returning to FIG. 17, the content data flow from the dashed line indicates the server device 1715 to the non-storage client device 1725 from the server 1715 1725 non-storage client. 在一个实现中,呈现的内容数据包括控制未授权拷贝的输出控制(例如,防止或抑制拷贝输出数据的数据或处理)。 In one implementation, presented content data includes output controls to control unauthorized copying (e.g., data or processing to prevent or inhibit copying of the output data). 某些服务器包括服务器和客户机功能性,并且这种服务器将类似于客户机地呈现内容。 Some servers including server and client functionality, and this would be similar to client server to render the content.

[0201] 图30示出了呈现存储在客户机设备上的子拷贝版本中的内容数据的客户机设备的一个实现的流程图3000。 [0201] FIG 30 illustrates an implementation of a client device presenting a sub-copy version stored on the client device the content data in flowchart 3000. 最初,客户机设备是存储客户机设备,并存储要呈现的锁定内容数据的子拷贝版本。 Initially, the client device is stored in the client device, lock and store sub-copy version to be presented content data.

[0202] 客户机接收呈现内容的请求(块3005)。 [0202] The client receives a request to render the content (block 3005). 该请求来自用户,并指示内容条目。 The request from the user, and instructs the content item. 在另一实现中,该请求来自另一设备,或是自动的。 In another implementation, the request is from another device, or automatically.

[0203] 客户机确认许可证允许呈现子拷贝版本(块3010)。 [0203] license allows the client to confirm the sub-copy version presented (block 3010). 当刷新许可证时,许可证可改变或更新,因此在呈现子拷贝版本之前,客户机检查许可证。 When the refresh license that can be changed or updated, so before presenting sub-copy version, check client licenses. 如果许可证不是当前的、不是有效的、或是禁止的,则客户机不会呈现子拷贝版本。 If the license is not current, not valid, or prohibited, the client does not render sub-copy version. 在一个实现中,如果客户机不具有当前有效且激活的许可证,则客户机请求来自服务器的新许可证,并且服务器参考相应绑定实例的根许可证。 In one implementation, if the client does not have a current and active license, the client requests a new license from the server, and the server with reference to the corresponding root license of the bound instance. 如果服务器拒绝该请求(例如,由于客户机没有权利使用新许可证),则该客户机不会呈现子拷贝版本。 If the server rejects the request (for example, because the client does not have the right to use license), the client does not render sub-copy version.

[0204] 客户机还确认该客户机不在该客户机可用的任何撤消列表上(块3015)。 [0204] The client also confirms that the client is not on any revocation list available to the client (block 3015). 如果客户机在撤销列表上,则客户机不会呈现子拷贝版本。 If the client is on the revocation list, the client does not render sub-copy version.

[0205] 在成功确认许可证和撤消列表之后,客户机呈现子拷贝版本的内容数据(块3020)。 [0205] After successfully verifying license and revocation lists, client rendering sub-copy version of the content data (block 3020). 客户机通过将锁定内容数据解密以产生输出数据并将该输出数据输出到集成呈现部件、外部呈现部件或终端设备来呈现子拷贝版本的内容。 The client decrypts the content data by locking to generate output data and the output data to integrated presentation components, external presentation components, or a terminal device to render the content of the sub-copy version. [0206] 顺从性设备以类似的方式呈现来自离散实例的内容数据。 [0206] compliant device presents content in a similar manner data from the discrete instance.

[0207] 如上所述,包含客户机功能性的服务器以类似的方式呈现内容数据。 [0207] As described above, the server comprises a client function in a similar manner of presenting the content data. 在另一实现中,服务器设备和客户机设备在同一物理设备上共存,并因此服务器依赖于常驻客户机来呈现内容。 In another implementation, the server device and client devices to coexist on the same physical device, and therefore the server relies on the client to render permanent the content.

[0208] 图31示出了将内容数据从服务器流到客户机的一个实现的流程图3100。 [0208] FIG. 31 shows the content data stream to a client from a server implementation flow chart 3100. 最初,月艮务器创建内容的绑定实例,并且客户机设备连接到该服务器。 Initially, the month that works to create binding instance content, and client devices connect to the server.

[0209] 客户机接收呈现内容的请求(块3105)。 [0209] The client receives a request to render the content (block 3105). 该请求来自用户,并指示内容的条目。 The request from the user, and indicates the entry content. 在另一实现中,请求来自另一设备,或者是自动的。 In another implementation, a request from another device or is automated. 客户机将流请求发送到管理当前请求所指示绑定实例的服务器。 Client request to the stream server management request currently indicated by the binding instance. 在另一实现中,服务器接收当前请求,并且该请求还指示呈现内容的客户机设备。 In another implementation, the server receives the present request and the request also indicates the client device to present the content.

[0210] 服务器确认根许可证允许通过流到指示的客户机来呈现内容数据(块3110)。 [0210] confirmed that the root license allows the server to present the content data (block 3110) indicated by the flow client. 当刷新许可证时,该许可证可改变或被更新,因此服务器在流来自绑定实例源版本的内容数据之前检查许可证。 When the refresh license, which can be changed or updated, so check the license server in the stream before the content data from the example source version binding. 如果许可证不是当前的、不是有效的或者是禁止的,则服务器不会流内容数据。 If the license is not present, is not valid or is disabled, the server does not stream content data. 服务器不会将内容数据流到不是集线器网络成员的客户机。 The content data server does not flow to a member of the hub network client.

[0211] 服务器还确认客户机不在该服务器可用的撤消列表上(块3115)。 [0211] The server also confirm that the client is not on a revocation list available to the server (block 3115). 如果客户机在可用撤销列表上,则服务器不会流内容数据。 If the client is available on the revocation list, the server will not stream content data.

[0212] 在成功确认许可证和撤销列表之后,服务器将内容数据从该绑定实例的源版本流到客户机(块3120)。 [0212] After successfully verifying the license and the revocation list, the server the content data from the source version of the bound instance of the stream to a client (block 3120). 在一个实现中,服务器将源版本的锁定内容数据流到客户机。 In one implementation, the server source version of locked content data stream to a client.

[0213] 当客户机接收到流内容数据时,该客户机呈现内容数据(块3125)。 [0213] When the client receives the streaming content data, the client presents the content data (block 3125). 客户机不存储流内容数据(除在呈现内容数据过程中的瞬变以外)。 The client does not store the streaming content data (except for transient data in the process of presenting content). 客户机通过将内容数据输出到集成呈现部件、外部呈现部件或终端设备来呈现内容数据。 The client by outputting content data to integrated presentation components, external presentation components, or a terminal device to present the content data.

[0214] 在另一实现中,服务器将锁定内容数据加密(例如,使用流数据的加密技术),并将加密的锁定内容数据流到客户机。 [0214] In another implementation, the server encrypts content data by the lock (e.g., streaming data using encryption techniques), and encrypted content data stream to a client lock. 客户机将加密的锁定内容数据解密以获得锁定内容数据,并然后将锁定内容数据解密以获得输出数据。 The client will lock contents encrypted data is decrypted content data to obtain the lock, and then lock the content data is decrypted to obtain output data. 客户机呈现该输出数据。 The client presents the output data. 在备选实现中,可使用服务器和客户机之间不同的加密和解密组合。 In alternative implementations, different between the server and the client encryption and decryption combinations thereof. 例如,服务器可将锁定内容数据解密以获得输出数据,并然后加密该输出数据。 For example, the server can decrypt the locked content data to obtain output data and then encrypt the output data. 服务器然后将加密的输出数据流到客户机,并且客户机对加密的输出数据解密。 The server then sends the encrypted output data stream to a client, and the client decrypts the encrypted output data.

[0215] 在一个实现中,顺从性设备可总是将数据输出到连接的终端设备,因为终端设备不存储接收的输出数据(除瞬变以外),并且到终端设备的连接和传输是相当安全的。 [0215] In one implementation, a compliant device can always output data to a terminal connected, because the output data received from the terminal apparatus is not stored (except transient), and the connection and transmission to the terminal device is quite safe of. 在一个实现中,当顺从性设备将输出数据发送到终端设备时,该顺从性设备将相同的数据发送到从该顺从性设备接收数据的所有终端设备。 In one implementation, when a compliant device sends output data to the terminal device, the compliant device sends the same data to all terminal devices compliant device from the received data.

[0216] 在一个实现中,顺从性设备会将离散内容流到另一顺从性设备,但接收设备不会存储任何流内容数据(除在呈现过程中瞬变以外)。 [0216] In one implementation, a compliant device will flow to discrete content to another compliant device, but the receiving device will not store any streaming content data (other than the transient during the rendering process).

[0217] 客户机设备不会流子拷贝版本的内容数据。 [0217] The client device will not stream the content data of the sub-copy version. 在另一实现中,存储客户机设备将子拷贝版本的内容数据流到另一成员客户机。 In another implementation, the storage client device sub-copy versions of content data stream to another member client.

[0218] 内容拷贝和移动 [0218] content copying and moving

[0219] 顺从性设备可从源版本创建子拷贝版本,或拷贝子拷贝版本。 [0219] compliant device can create a sub-copy version from a source version or copy sub-copy version. 顺从性设备可随意将子拷贝版本提供给集线器网络的另一成员。 Compliant device can freely provide a sub-copy version to another member of the hub network. 顺从性设备可将子拷贝版本提供给不是绑定实例绑定到的集线器网络的成员的顺从性设备,但在能够呈现子拷贝版本的内容数据之前,非成员将需要获得新的有效许可证。 Before compliant device can be sub-copy version available to members of the compliance device is not binding instance is bound to the hub network, but can be presented in the sub-copy version of the content data, non-members will need to obtain a new valid license. 顺从性设备可将子拷贝版本提供给非顺从性设备,但该非顺从性设备将不能呈现子拷贝版本的锁定内容数据。 Compliance device can be sub-copy version available to non-compliant equipment, but the non-compliant device will not render sub-copy version of locked content data. 非顺从性设备可将子拷贝版本移动到顺从性设备,且该顺从性设备在获得新的有效许可证之后将能呈现该子拷贝版本。 Non-compliant devices can be moved to the sub-copy version compliant device, and the compliance of the new equipment after obtaining a valid license will be able to show the sub-copy version.

[0220] 顺从性设备不会拷贝离散实例(除在集线器网络上将实例从离散变为绑定的过程中以外)。 [0220] compliant device will not copy a discrete instance (other process on a network hub instance from discrete changes other than bound). 类似地,顺从性设备不会创建离散实例的备份拷贝。 Similarly, the compliant device does not create a backup copy of discrete instances. 顺从性设备可产生离散实例锁定内容数据的离散版本的拷贝(类似于子拷贝版本),并将该拷贝提供给另一设备,但在能够呈现锁定内容数据的接收拷贝之前,接收设备将需要获得新的有效许可证。 Before compliant device may produce discrete locked content data of a discrete instance version copies (similar to the sub-copy version) and provide that copy to another device, but can present to receive the copy locked content data, the receiving device will need to obtain the new valid license.

[0221] 服务器不会将源版本和根职责直接移到另一服务器。 [0221] The server does not release the source and root functions directly to another server. 在一个实现中,为了将根职责从一个服务器移到另一服务器,服务器将绑定实例转换为离散实例,将离散实例移动到另一服务器,且第二服务器将离散实例转换回绑定实例,建立新根。 In one implementation, to move root responsibility from one server to another, a server converts the bound instance to a discrete instance, moves the discrete instance to another server, the second server and converted back to a discrete instance binding instance, establish new roots. 跨越设备可通过允许服务器通过跨越设备将离散实例传到另一顺从性服务器来便于离散实例从一个集线器网络到另一集线器网络的传送。 By allowing the server device may span across the device by the discrete instance to another compliant server passes to facilitate transferring discrete instance from one hub network to another hub network. 在另一实现中,服务器将根职责直接移到共享公共客户机设备的另一顺从性服务器。 In another implementation, the server will move directly to the root of responsibilities shared another common client devices compliant server. [0222] 服务器不会将源版本或根职责移动到客户机(除非该客户机也是服务器)。 [0222] The server does not release the source or root duty move to the client (unless the client is also a server).

[0223] 顺从性设备可使用顺从性媒体、安全传输或顺从性记录技术移动离散实例。 [0223] compliant device may use compliant media, secure transmission, or compliant recording technologies mobile discrete instance. 如上参考从绑定实例创建离散实例所述,在一个实现中,在将离散实例移动到外部媒体之前,顺从性设备确认该外部媒体是顺从性媒体。 Examples of the above with reference to creating a discrete instance from a bound, in one implementation, before moving the discrete instance to external media, the compliant device confirms that the external media is compliant media. 如果顺从性媒体不可用,则顺从性设备可使用批准的记录技术在非顺从性媒体上创建非顺从性拷贝。 If compliant media is not available, the compliant recording apparatus can be used to create non-approved techniques compliant copy on non-compliant media. 一旦顺从性设备已经创建了非顺从性拷贝,该非顺从性拷贝就不能够再次绑定。 Once the compliance of equipment have created a non-compliant copy, the copy of the non-compliance will not be able to bind again. 相应地,在创建非顺从性拷贝之前,顺从性设备请求确认。 Accordingly, before creating the non-compliant copy, the compliant device requests confirmation. 如果外部顺从性媒体不可用,并且批准的记录技术不可用,则顺从性设备不会将离散实例移动到外部存储器。 If external compliant media is not available and approved recording technology is not available, the compliant device will not move the discrete instance to external storage.

[0224] 顺从性设备使用安全传输将子拷贝版本传输到其它顺从性设备。 [0224] compliant devices using a secure transmission of the sub-copy version to another compliant device transfer. 在另一实现中,顺从性设备也可经过非安全连接传输子拷贝版本(没有许可证或密钥)。 In another implementation, compliant devices can be connected via a non-secure transmission sub-copy versions (without licenses or keys). 顺从性设备还可使用顺从性物理媒体来将子拷贝版本传送到另一顺从性设备,这受在此所述的限制控制。 Compliant device can also use compliant physical media to transfer the sub-copy version to another compliant device, subject to this restriction control described herein.

[0225] 图32示出了创建成员客户机的锁定内容数据的子拷贝版本的一个实现的流程图3200。 [0225] FIG 32 illustrates an implementation of a client to create a member of the sub-copy version of locked content data 3200 of the flowchart. 最初,服务器管理内容的绑定实例,存储绑定实例的源版本和根许可证。 Initially, the binding instance of the server to manage content, source version store binding instance and root license. 如上所述,服务器使用源版本以产生集线器网络的子拷贝版本。 As described above, the server uses the source version to produce the sub-copy version of the network hub.

[0226] 服务器接收创建子拷贝版本的请求(块3205)。 [0226] The server receives the sub-copy version of the request (block 3205) created. 该请求来自用户,并指示内容条目和接收子拷贝版本的客户机。 The request from the user, and content items and indicate reception of a copy version of the client. 备选地,拷贝请求没指示新子拷贝版本的目的地(例如,拷贝请求之后是将新的子拷贝版本移动到目的客户机的请求)。 Alternatively, the copy request indicates no new sub-copy version of the destination (e.g., after the copy request is to move the new sub-copy version to the requesting client object). 在另一实现中,该请求来自另一设备,或者是自动的。 In another implementation, the request is from another device or is automated. 在另一实现中,客户机接收拷贝请求,并将该请求传到服务器。 In another implementation, a client receives the copy request, and the request to the server. 在一个实现中,拷贝请求指示目标分辨率。 In one implementation, the copy request indicates a target resolution. 如果目标分辨率不同于源版本(或拷贝的子拷贝版本)的分辨率,则可使用作为集线器网络中最高分辨率拷贝的源版本(或拷贝的子拷贝版本)来进行转换。 If the target resolution is different from the source version (or sub-copy version copy) resolution, it can be used as the source version of the highest resolution copy in the hub network (or sub-copy version copy) to convert. 在另一实现中,拷贝请求指示目标格式。 In another implementation, the copy request indicates a target format. 服务器使用要拷贝的子拷贝版本或源版本来执行作为部分拷贝过程的任何代码转换。 The server uses the sub-copy version to be copied or the source version to execute any code as part of the copying process of conversion. 备选地,在客户机需要时,可将目标分辨率和格式转换和代码转换用于呈现。 Alternatively, when the client needs, target resolutions and formats can be converted and transcoded for rendering.

[0227] 服务器确认许可证允许将子拷贝版本提供给指示的客户机(块3210)。 [0227] The server confirms the license allows the sub-copy version indication provided to the client (block 3210). 当刷新许可证时,该许可证可改变或被更新,因此服务器在创建子拷贝版本之前检查该许可证。 When the refresh license, which can be changed or updated, the server checks the license before creating the sub-copy version. 如果许可证不是有效的,或者是禁止的,则服务器不会创建子拷贝版本。 If the license is not valid, or is disabled, the server does not create a sub-copy version. 如下所述,在另一实现中,在产生子拷贝版本之前,服务器不确认许可证。 Described below, in another implementation, prior to generating a sub-copy version, the server does not confirm the license. 相反,在创建子拷贝版本的新许可证时,服务器检查许可证。 In contrast, when you create a new sub-copy version of the license, check the license server.

[0228] 服务器还确认客户机不在服务器的撤消列表上(块3215)。 [0228] The server also confirmed that the client is not in the revocation list server (block 3215). 如果客户机在撤消列表上,则服务器不会创建子拷贝版本。 If the client is on the revocation list, the server does not create a sub-copy version.

[0229] 在成功确认许可证和撤销列表之后,服务器创建子拷贝版本(块3220)。 [0229] After successfully verifying license and revocation list, create a sub-copy version of the server (block 3220). 服务器从源版本创建新的子拷贝版本,将该新子拷贝版本存储在服务器上。 The server creates a new sub-copy version from the source version, the new sub-copy version stored on the server. 参考图23,服务器从源版本2310创建子拷贝版本2355。 Referring to FIG 23, the server creates the sub-copy version 2355 from a source version 2310. 服务器还拷贝包含许可授权信息的标题信息。 The server also contains a copy of the licensing information in the header information. 服务器不拷贝根许可证、解开锁定内容数据的密钥或源版本的撤消列表。 The server does not copy the root license, unlock key or data source version of the content revocation list. 服务器根据根许可证创建子拷贝版本的新子拷贝许可证。 The new sub-copy license server to create a sub-copy version of the license based on the root. 然而,最初禁止新子拷贝版本的许可证。 However, the new sub-copy version of the original license is prohibited. 为了激活该许可证或接收新的许可证,接受客户机将联系服务器,以刷新许可证,并接收对新子拷贝版本特定的新许可证。 In order to activate the license or receive a new license, will accept the client contacts the server to refresh the license, and receive a new license for the new sub-copy version specific. 在一个实现中,服务器为新子拷贝版本提供激活的许可证。 In one implementation, the server provides a license for the activation of the new sub-copy version. 当服务器将许可证提供给客户机时,该服务器基于服务器的撤销列表提供解开子拷贝版本的密钥和撤销列表。 When the license server to the client, the server revocation list based servers provide sub-copy version unlock keys and revocation lists. [0230] 在创建新的子拷贝版本之后,服务器将新子拷贝版本移动到目的客户机(块3225)。 [0230] After creating a new sub-copy version, the server moves the new sub-copy version to the destination client (block 3225). 在一个实现中,为了移动新的子拷贝版本,服务器将新子拷贝版本的另一拷贝以及任何伴随数据(例如许可证)发送到客户机,并删除服务器上的第一个新子拷贝版本。 In one implementation, in order to move a new sub-copy version, the server another copy of the new sub-copy version and any accompanying data (eg license) sent to the client, and remove the first new sub-copy version on the server. 客户机接收并存储该新子拷贝版本。 The client receives and stores the new sub-copy version. 在另一实现中,服务器直接在客户机上创建新子拷贝版本,并因此跳过块3225。 In another implementation, the server creates a new sub-copy version directly on the client, and the block 3225 is skipped. 在另一实现中,服务器响应来自客户机对新许可证的请求而随后创建并提供子拷贝许可证。 In another implementation, the server responds to requests from clients and then create a new license and provide sub-copy license.

[0231] 在另一实现中,根许可证允许产生有限数量的子拷贝版本。 [0231] In another implementation, the root license allows a limited number of sub-copy version. 在此情况下,服务器保存产生的子拷贝版本的数量的计数(例如,通过计算已从根许可证产生子拷贝许可证的次数),将拷贝计数存储在根许可证中。 In this case, the server holding the number of generated sub-copy version of the count (e.g., the number of sub-copy license is generated by calculating from the root license), the copy count stored in the root license. 如果已达到极限,则服务器不会从绑定实例的源版本中产生另一子拷贝版本。 If the limit has been reached, the server does not generate another sub-copy version from the source version binding instance. 如果通知服务器删除或禁止,则可通过删除或禁止集线器网络中的子拷贝版本来减少拷贝计数。 If you remove or disable the notification server, can be reduced by removing or disabling copying count sub-copy version of the hub network.

[0232] 在另一实现中,仅允许客户机具有特定数量的许可证。 [0232] In another implementation, only allowing the client having a certain number of licenses. 当客户机接收到新的子拷贝版本和子拷贝许可证时(通过拷贝或移动),该客户机确定是否已经超过许可证上客户机的极限。 When the client receives the new sub-copy version and sub-copy license when (by copying or moving), the client determines whether the license limit has been exceeded the client. 如果超过,则客户机禁止新子拷贝版本的许可证,直到禁止某些其它许可证以使许可证的数量再次低于该极限为止。 If so, then the client is prohibited sub-copy version of the new license until the license prohibits certain other so that the number of licenses was below the limit again.

[0233] 在一个实现中,存储客户机设备还可产生存储在客户机上的子拷贝版本的拷贝。 [0233] In one implementation, the storage client device may also generate a copy of the sub-copy version stored on the client machine. 在此情况下,存储客户机设备产生如上参考图32所述的服务器的子拷贝版本。 In this case, the storage client device generating a sub-copy version of the server 32 described above with reference to FIG.

[0234] 在一个实现中,以类似的方式处理移动子拷贝版本的请求。 [0234] In one implementation, the process moves to a similar manner to the sub-copy version of the request. 服务器或客户机接收该请求,并确认许可证允许子拷贝版本移动到指示的客户机。 Server or client receives the request and confirming that the license allows the sub-copy version is moved to the indicated client. 服务器或客户机确认该指示的客户机不在服务器或客户机的撤销列表上。 Server or client to confirm the revocation list that indicates the client is not in server or client. 如果确认成功,则服务器或客户机将子拷贝版本和任何相应数据(例如许可证)移动到指示的客户机。 If the confirmation is successful, the server or client sub-copy version and any corresponding data (e.g., license) to the indicated client.

[0235] 在另一实现中,客户机可在没有确认的情况下移动和拷贝子拷贝版本,但不会移动或拷贝许可证。 [0235] The client and the movable copy of a copy version, but will not move or copy licenses without confirmation in another implementation. 类似地,在没有首先确认根许可证和撤销列表的情况下,服务器可创建和分配子拷贝版本。 Similarly, in the case without first confirming root license and revocation list, the server can create and assign sub-copy version. 在此情况下,服务器和客户机可没有限制地将子拷贝版本分配给顺从性和非顺从性设备。 In this case, the server and the client may, without limitation, the sub-copy version is assigned to non-compliant and compliant equipment. 非顺从性设备将不能够呈现锁定内容数据,但可将子拷贝版本传到顺从性设备。 Non-compliant devices will not be able to present the data locked content, but the sub-copy version can be passed compliance equipment. 在能够呈现子拷贝版本的锁定内容数据之前,接受顺从性设备将得到许可证(例如,如子拷贝版本标题中的许可授权信息所指示的)。 Before presenting the sub-copy version can be locked content data, accept the license will be compliant device (eg, as licensing sub-copy version of the information indicated in the title). 在另一实现中,客户机可移动许可证的拷贝,以将该许可证提供给断开的成员客户机。 In another implementation, the mobile client may copy the license to provide the license to a disconnected member client.

[0236] 当服务器和客户机将子拷贝版本提供给不是集线器网络成员的顺从性设备时,月艮务器和客户机不给子拷贝版本提供有效许可证。 [0236] When a server and client sub-copy version will be available to members of the network hub is not compliant device, that works to month, and the client does not provide a valid license to the sub-copy version. 接受者随后使用存储在子拷贝版本中的许可授权信息来获得有效许可证。 The recipient then uses the licensing information is stored in the sub-copy version to obtain a valid license. 以这种方式,顺从性设备可将子拷贝版本分配给其它集线器网络。 In this manner, the compliant device may be assigned to the sub-copy version to other hub networks.

[0237] 在备选实现中,以绝对项定义本地环境,诸如以定义的地点为中心半径为100米的圆。 [0237] In an alternative implementation, a local environment is defined in absolute terms, such as in the location defined by the center circle radius of 100 meters. 例如,可将媒体限制于在特定物理位置使用,诸如限制在特定建筑物的绝密文件。 For example, media may be restricted to use in a particular physical location, such as confidential documents is limited to a specific building. 如上所述,当设备离开本地环境时,该设备从集线器网络断开(虽然该设备仍可以是成员)。 As mentioned above, when the device leaves the local environment, the device is disconnected from the hub network (although the device may still be a member). 在此情况下,服务器可从其自己的集线器网络断开,并因此在断开服务器时,没有设备能够刷新该集线器网络的许可证,包括服务器。 In this case, the server can be disconnected from its own network hub, and so when the server is disconnected, the device can not permit the hub network refresh, including the server. 在另一备选实现中,集线器网络不受本地环境限制。 In another alternative implementation, hub networks are not restricted local environment. 在此情况下,当设备不能与服务器通信时(例如,物理或网络连接中断时),该设备不能刷新许可证。 In this case, when (for example, a physical or network connection is broken) device can not communicate with the server, the device can not refresh the license.
