具体实施方式 detailed description

以下针对发明结构及作用参考附图详细说明。 The following detailed description for the structure and function of the invention with reference to the accompanying drawings.

图1显示的是根据本发明的多重单元数字卫星播放接收用PVR IRD系统的存储空间灵活使用方法。 Figure 1 shows a player receiving PVR IRD storage system using a flexible multi-unit of the digital satellite method of the present invention.

上述系统在多房间控制(Multi-room)环境下利用无线局域网(LAN)连接了多个PVR IRD系统。 Connecting a plurality of the above-described system using a PVR IRD wireless local area network system (LAN) under the control of multi-room (Multi-room) environment.

如图1所示,多重单元PVR IRD系统接收到如NTSC,ATSC或者数字卫星播放信号等播放信号,同时对通过PVR的存储媒体(简称为'IRD的存储空间'或者'IRD的HDD')以存储的服务器IRD和上述服务器和无线局域网相连。 As shown, the IRD PVR multiple unit system receives the broadcast signal, such as NTSC, ATSC digital satellite broadcast signal or the like, at the same time by the PVR storage medium (referred to as 'the IRD storage' or 'the IRD's HDD') 1 to IRD and the storage server and said server is connected to the wireless LAN. 同样的存储媒体以存储的多个客户端(Client)IRD所构成。 The same storage medium to store a plurality of client (Client) IRD formed. 上述服务器IRD当中,安装有无线局域网集线器(Hub),因此可以与上述多数客户端IRD相连,通过此得以进行无线局域网通信。 Among the above-mentioned IRD server, the wireless LAN is attached to the hub (the Hub), it can be coupled to said client IRD most, this is performed by wireless LAN communication.

如此构成的PVR IRD系统运作关系如下。 PVR IRD system operational relationship thus constituted as follows.

使用上述客户端IRD 1的使用者想录制程序时,假设客户端IRD 1的硬盘使用空间很充分,直接使用该空间即可。 Using the above client IRD 1 when the user wants to record the program, assuming the client to use hard disk space IRD 1 very good, the space can be used directly.

但是,如图1所示,客户端IRD 1因为已经几乎使用完存储空间,导致存储空间的不足。 However, as shown in FIG. 1, the IRD 1 as a client has been almost used up storage space, resulting in a shortage of storage space.

此时,客户端IRD 1会在网络中检索目前不在使用中的其他IRD后,假设在检索到的IRD有其充分的空间,就会使用在它的IRD存储空间录制程序的方法。 At this time, the client can retrieve additional IRD IRD 1 is not currently in use on the network, it is assumed that there is sufficient space in the search to the IRD, it will be used in the method of IRD storage space to record the program.

图2显示的就是如上所述的IRD检索及录制阶段。 Figure 2 shows the IRD is as described above and record retrieval stage.

如图2所示,IRD检索以及录制阶段大致分为IRD检索阶段和对检索到的IRD进行录制要求及录制的阶段。 As shown in FIG. 2, IRD record retrieval phase and the retrieval phase are roughly classified into IRD and the IRD stage of the retrieved record and recording requirements.

上述IRD检索阶段是在网络上搜索目前不在使用中的、具有充分存储空间IRD的阶段。 IRD above retrieval phase search on a network currently not in use, the IRD has sufficient storage space stage.

目前使用中的客户端IRD 1通过服务器IRD向客户端IRD 2发送为了获取IRD的目前是否使用及可使用的存储空间容量的信息。 Currently used in the client information. 1 IRD IRD 2 transmits the IRD in order to obtain the current storage capacity and can be used whether the IRD through the server to the client.

继而,客户端IRD 2会向客户端IRD 1发送含有目前状态的信息。 Then, the IRD 2 client information transmitted to the client will contain the current state of IRD 1 side. 上述客户端IRD 1通过上述状态信息判断是否可以录制。 Whether or not the IRD 1 via the client determines the status information may be recorded.

此时,当客户端IRD 2不足以录制时,会检索其他IRD。 At this time, when the client IRD 2 is not sufficient to record, retrieve other IRD. 在适当的情况下,转向向检索出的IRD进行录制要求及录制阶段。 In appropriate circumstances, the steering claim recording and recording stage to the retrieved IRD.

上述录制要求阶段中,会向检索到的IRD发送含有为了录制的频道及程序信息(开始时间、结束时间)的信息,要求录制。 In the above-described recording requirements phase, containing the information sent to the channel and the program information recording (start time, end time) to the IRD retrieved, the recording requirements. 受到要求的客户端IRD 2向客户端IRD 1发送录制开始信息,从而开始录制阶段。 Subject to the requirements of clients IRD 2 to the client IRD 1 to send information recording start end to start recording stage.

当结束上述录制时,客户端IRD 2向客户端IRD 1发送录制结束信息,从而结束录制。 When the completion of the recording, client record IRD 2 IRD 1 transmits end information to the client, to end recording.

这样录制的程序通过后续使用者的过程得以播放,而这一过程显示在了图3到图5。 Such a program is recorded subsequent playback by a user process, while the process shown in FIGS. 3 to 5.

图3代表的是各自IRD所保留的录制程序。 Figure 3 represents the respective IRD reserved recording program.

如图3所示,目前使用中的客户端IRD 1的使用者当需要把录制的程序播放时,可以使用两种方法。 As shown in FIG. 3, the current user using the client when IRD 1 need to play the recorded program, two methods can be used. 第一就是检索客户端IRD 1内HDD所录制的程序目录而播放所需的程序;第二就是检索在其他IRD(服务器IRD,客户端IRD 2)中所录制的程序目录,从而播放所需程序的方法。 The first is the search client IRD 1 HDD recorded program directory and the desired player; retrieve other is a second IRD (IRD servers, clients IRD 2) recorded in the program directory, so that playing said desired program Methods. 此时,考虑到客户端IRD 1的使用者等级(例如:18岁以下,未满12岁),控制为只能检索并播放许可的程序。 In this case, taking into account the client IRD user level 1 (example: 18 years of age, under 12 years old), control and retrieve only player permitted.

上述第二个方法即检索其他IRD持有的程序目录阶段展现在图4中。 Said second method i.e. to retrieve additional program directory IRD hold stage 4 show in FIG.

如图4所示,目前使用中的客户端IRD 1向客户端IRD 2要求所录制的程序,上述客户端IRD 2会把录制的程序目录信息发送到上述客户端IRD 1当中。 As shown, the client is currently using the IRD 1 IRD 2 to the client terminal recorded claim 4, said client program is transmitted IRD 2 will record the directory information to the IRD 1 among said client.

通过这些过程客户端IRD 1会检索各个IRD持有的程序目录,而客户端IRD 1的使用者通过检索到的程序目录选择播放所需的程序。 Through these processes client IRD 1 will retrieve the various program directory IRD held, and the client user IRD 1 through the retrieved program directory Select the program required for playback.

如此,将要播放的程序存储在使用中的IRD内HDD时即可播放,但是在其他IRD的HDD时,要向其IRD要求播放所需程序。 Thus, the program to be played is stored in the IRD can use the playback HDD, an HDD, in other IRD, the IRD requirements to which the desired program playback.

图5显示的是播放其他IRD的HDD中存储的录制程序过程。 Figure 5 shows a recording procedure of IRD other player stored in the HDD.

如图5所示,在检索的程序中播放所需的程序在客户端IRD 2时,客户端IRD 1会向上述客户端IRD 2发送希望播放的程序信息和播放要求信息。 5, the program retrieves the required player IRD 2 on the client, the client will IRD 1 IRD 2 to send said client information and the desired program information Play requirements.

此后,客户端IRD 2从客户端IRD 1的HDD读取受要求的程序,通过无线局域网发送。 Thereafter, the client program by the IRD 2 is read from the HDD client requirements IRD 1 transmits through the wireless LAN.

上述客户端IRD 1接收到客户端IRD 2发送的程序后,时时进行播放。 Said client after the client receives IRD. 1 IRD 2 sends, from time to time to play.

通过以上说明的内容,如果是相关从业者在没有脱离本发明的技术思想的范围内,可以进行丰富的变化及修改。 The content described above, if it is relevant practitioners in the art without departing from the scope of the inventive idea can be a wealth of variations and modifications.

继而,本发明的技术范围不是只局限于所记载的内容,而是取决于专利申请范围。 In turn, the technical scope of the present invention is not limited to the contents described, but on the scope of the patent application.
