[0004] II.相关技术 [0004] II. Related Art

[0005] 计算机、电子游戏相关的产品、W及各种视频技术(例如,DVD和高清晰度的VCR) 在过去几年大大进步,即使在包括某类文本时,也能将具有更高分辨率的静态、视频、视频点播、W及图形图像显现给送种设备的终端用户。 [0005] Computers, electronic game related products, W and various video technologies (for example, DVD and high-definition VCR) much progress over the past few years, even when including some text, but also can have a higher resolution still, video, video on demand, W, and graphic images appear to the end user of the device feeding species. 送些进步又要求使用较高分辨率的电子观看装置,譬如高清晰度视频监视器、皿TV监视器、或专用图像投射元件。 These advances in turn required to send a higher resolution electronic viewing devices such as high definition video monitors, TV monitors dish or specialized image projection elements. 为了为终端用户创建更真实的、内容丰富的、或真实的多媒体体验,使用了送种可视图像与高清晰度或高质量的音频数据的组合,譬如当使用CD类型的声音再现、DVD、W及其它也具有相关音频信号输出的装置时。 In order for end users to create a more realistic, content rich, or true multimedia experience, we use a combination of types of visual images and send high-definition or high-quality audio data, such as when using CD type sound reproduction, DVD, W and also other related devices when the audio signal output. 此外,为了仅将音频显现给终端用户,开发了高移动性、高质量的声音系统和音乐传输机制,譬如MP3放音机。 In addition, in order to show only the audio to end users, the development of highly mobile, high quality sound systems and music transport mechanisms, such as MP3 cassette player.

[0006] 在典型的视频显现情况下,视频数据一般用当前技术来传送,传送速率最好为慢和中等,在每砂一到十千比特的数量级上。 Under [0006] In a typical video presentation, the video data is generally transmitted with the current technology, the transmission rate is preferably slow and medium in the sand on each one to ten kilobits magnitude. 然后,该数据或被缓冲或被存储在瞬变或较长期限的存储装置中,为了延后的(稍后)在期望观看装置上的显示。 Then, the data in the storage means or buffer or transient or longer term, for delayed (later) stored in the display of a desired viewing device. 例如,为了接收或发送W 数字再现一图像时有用的数据,图像可W"通过"或用互联网来传送,使用驻留在带有调制解调器或互联网连接装置的计算机上的程序。 For example, useful when W to receive or transmit digital image data of a reproduced image may be W "through" or using the Internet to transmit, using a program resident on a computer with a modem or Internet connection device. 当使用诸如配有无线调制解调器的便携式计算机、或无线个人数据助理(PDA)、或无线电话送样的无线装置时,类似的传送也会发生。 When using a wireless device with a wireless modem, such as a portable computer, or a wireless personal data assistant (PDA), a wireless telephone or send samples of similar transfer can occur.

[0007] 数据一旦被接收,就为了回放而被本地存储在包括外部存储装置在内的存储元件、电路或装置中,譬如RAM或闪存。 Once the [0007] data is received, it is played back to the memory elements, circuits or devices comprises an external storage device including, a local storage such as a RAM or a flash memory. 根据数据数量和图像分辨率,回放可W相对快地开始, 或者在较长延时后被显示。 The amount of data and the image resolution, the playback W can begin relatively quickly, or displayed after a longer delay. 也就是说,在某些情况下,图像显现对于很小和低分辨率的不需要许多数据的图像允许某种程度的实时回放,或允许使用某类缓冲,W便在小延时后显现一些素材,而更多的素材被传送。 In other words, in some cases, the image appears for small and low-resolution image does not require a lot of data to allow a certain degree of real-time playback, or allow the use of certain types of buffer, W will appear in a small number of delay material, and more material is transferred. 假定传送链路中没有障碍,郝么一旦显现开始,传送对于观看装置的终端用户而言就是合理透明的。 Transmission link is assumed that there are no obstacles, Hao once it begins to show, to the end user viewing the transfer means is reasonable in terms of transparency.

[0008] 用于创建或静态图像或运动视频的数据通常用多种已知技术之一被压缩,譬如由联合图像专家组(JPEG)、运动图像专家组(MPEG)、W及媒体、计算机和通信工业中为了加速通信链路上的数据传送的其它著名标准组织或公司所规定的技术。 One [0008] or used to create a still image or motion video data is typically compressed using a variety of known techniques, such as by the Joint Photographic Experts Group (the JPEG), Moving Picture Experts Group (MPEG), W and the media, computer, and in order to accelerate technology known standards organizations or companies other data on the communication link specified in the communication industry. 送能通过使用较少数量的比特来传送给定量的信息而更快地传送图像或数据。 Sent by using a smaller number of bits to transfer a given amount of information transmitted or the image data faster.

[0009] -旦数据被传送到诸如计算机送样的"本地"装置或其它装置,所产生的信息是未压缩的(或用专口解码播放机播放)并且准备好基于相应可用的显示分辨率和控制要素的适当显示。 [0009] - Once the data is transferred to a "local" device such as a computer or other device to send samples of the generated information is not compressed (or played using special mouth decoding players) and is ready to display resolution based on the corresponding available and controlling appropriate display elements. 例如,用X乘Y像素的屏幕分辨率表示的典型计算机视频分辨率一般从低达480x640,经过600x800 -直到1024x1024,然而也可W或根据期望或根据需要而使用多种其它分辨率。 For example, a typical computer video resolution Y by the screen resolution pixels indicated by X in general from as low as 480x640, through 600x800 - up to 1024x1024, but may be W or as necessary or as desired using a variety of other resolutions.

[0010] 图像显现也受到图像内容W及给定视频控制器操纵图像的性能的影响,该性能用预定义的色彩电平或色彩深度(用于产生色彩的每像素比特)和密度来表示,并且可W使用任何附加的开销比特。 [0010] The image reproduction is also affected by the image content and W given video controllers to manipulate the image performance, the performance (bits per pixel used to generate colors) and a density of a predefined color levels or color depth expressed, W may be used and any additional overhead bits. 例如,典型的计算机显示会期望任何地方从约为8到32每像素比特或更多来显示各种色彩(阴影和色度),然而也会遇到其它值。 For example, a typical computer display would expect anywhere from about 8 to 32 bits per pixel or more displays various colors (chromaticity and shaded), although other values ​​are encountered.

[0011] 从上述值可W看见,给定的屏幕图像要求从2. 45兆比特(Mb)到约为33. 55Mb的任何地方传输数据,分别从最低到最高的典型分辨率和深度的范围上。 [0011] W can be seen from the above value, the requirements of a given screen image from 2.45 Megabits (Mb) to around 33. 55Mb anywhere transmission data, and resolution typically range respectively from lowest to highest depth on. 当W每砂30顿的速率观看视频或运动类型的图像时,所需的数据量约为每砂73. 7到1006兆比特(Mbps),或约为每砂9. 21到125. 75兆比特(MBps)。 When W per 30 tons of sand at a rate of watching a video or motion type images, data required for each of the sand is about 73.7 to 1,006 Megabits (Mbps), or about every sand from 9.21 to 125.75 megabytes bits (MBps). 此外,人们可能期望结合图像一起显现音频数据,譬如对于多媒体显现而言,或作为分开的高分辨率音频显现,譬如CD质量音乐。 In addition, it may be desirable to combine the image appear together with audio data, for example, in terms of multimedia show, or appear as a separate high resolution audio, such as CD-quality music. 也可W使用交互指令、控制或信号的附加信号处理。 W interactive instructions may also be used, additional signal processing or control signals. 送些选项的每一个都添加了更多要被传输的数据。 Send some of each option to add more data to be transmitted. 在任何情况下,当人们为了创建内容丰富的体验而期望将高质量或高分辨率的图像数据W 及高质量的音频信息或数据信号传输到终端用户时,在显现元件W及用于提供送种数据类型的源或主机装置之间要求高数据传送速率链路。 In any case, when the people in order to create a content rich experience and the desired image quality and data W or high resolution quality audio information or data signals to an end user, appear in the W element and means for providing feed a high data transfer rate link is required between the data types of the source or host device.

[0012] 每砂约为115千字节(邸PS)或920千字节(肺PS)的数据速率可由现代串行接口常规处理。 [0012] Each of the sand is about 115 kilobytes (Di PS) or 920 kilobytes (lung PS) data rate by some modern serial interfaces conventional treatment. 其它诸如USB串行接口送样的接口可W提供速率高达12MBPS的数据传送,而诸如用电气和电子工程师协会(I邸巧1394标准配置的专用高速传输会发生在50到lOOMBps 的数量级上。不幸的是,送些速率达不到上述讨论的期望高数据速率,所构想的上述高数据速率用于将来无线数据装置和服务,用于为激励便携式视频显示器或音频装置提供高分辨率的、内容丰富的输出信号。此外,送些接口要求使用大量用于操作的主机或系统W及客户机软件。它们的软件协议堆找也创建了大量不期望的开销,尤其当考虑移动无线装置或电话应用时。而且,一些送样的接口使用了庞大电缆,它们对于面向高度审美的移动应用而言太笨重并且不令人满意,增加成本的复杂连接器,或者仅仅是消耗了太多功率。 Others, such as USB serial interfaces to send samples of the interface W provides data transfer rates of up to 12MBPS, and as with the Institute of Electrical and Electronics Engineers (dedicated high speed transmission I Di Qiao 1394 standard, can occur on the order of 50 to lOOMBps was unfortunate is not desirable to send some of the rate of the above-discussed high data rates, high data rates contemplated for future wireless data devices and services for providing high resolution excitation portable video display or an audio device, content rich output signal. in addition, these interfaces require the use of feed systems or W, and the host client software to operate a large number of. their software protocol stacks also create a lot to find an undesirable overhead, especially when considering the mobile wireless devices or telephone applications time. Also, some kind of interface to send a large cable, they are cumbersome for highly aesthetic oriented mobile applications and is not satisfactory, the cost of increasing the complexity of the connector, or simply consume too much power.

[0013] 还有其它熟知的接口,譬如模拟视频图形阵列(VGA)接口、数字视频交互式值VI) 接口或千兆比特视频接口(GVIF)。 [0013] There are other known interfaces such as the Analog Video Graphics Array (VGA) port, a digital video interactive value VI) interface or Gigabit Video Interface (GVIF). 前两个是并行类型的接口,它们W较高的传输速率处理数据,但也使用笨重的电缆并消耗在若干瓦特数量级上的大量功率。 The first two are parallel type interfaces which W higher transmission rate of data processing, but also to use heavy cables and consume large amounts of power on the order of several watts. 送两种特性都不能用于便携式消费者电子装置。 Send two features can not be used in portable consumer electronic devices. 即使第H种接口也消耗太多功率并使用了昂贵或庞大的连接器。 H species even when the first interface consumes too much power and uses expensive or bulky connectors.

[0014] 对于某些上述接口,W及非常高速率的数据系统/协议或与用于固定安装计算机设备的数据传送相关的传送机制而言,存在另一个主要的缺点。 [0014] For some of the above interfaces system data, W, and a very high rate / protocols or transfer mechanisms associated with data transfers for fixed installation computer equipment, there is another major drawback. 为了提供期望数据传送速率,也要求大量功率和/或高电流电平下的操作。 In order to provide the desired data transfer rates also requires a large amount of power in operation and / or high current levels. 送大大减少了送种技术对于高度移动的面向消费者的产品的有用性。 Sent to greatly reduce the usefulness of the seed delivery technology for highly mobile consumer oriented products.

[0015] 一般而言,为了用诸如光纤类型的连接和传送元件等选择对象来提供送种数据传送速率,郝么相对于对于实际商用面向消费者的产品所期望的而言,也要求一些引入复杂度和成本的附加转换器和元件。 [0015] In general, to connect with the transfer member and the like to select an object such as the type of fiber types to provide transmission data transfer rate, it HAO with respect to the actual commercial consumer oriented product is desired, it also requires the introduction of some additional converters and elements of complexity and cost. 除了至今为止的光学系统的一般昂贵特性之外,它们的功率要求和复杂度阻碍了轻量、低功率、便携式应用的一般使用。 In addition has generally expensive characteristics of the optical system until the outside, their power requirements and complexity hinders lightweight, low power, portable applications generally used.

[0016] 便携式或移动应用工业中所缺乏的是一种为高度移动终端用户提供高质量显现体验的技术,无论是基于音频、视频或是多媒体。 [0016] Portable or mobile applications in industry lacks a method of providing a high quality appearance is highly mobile end-user experience technology, whether it is based on the audio, video or multimedia. 也就是说,当使用便携式计算机时,如无线电话、PDA、或其它高度移动通信装置或设备,当前使用的视频或音频显现系统或装置完全不能W期望的高质量水平传递输出。 That is, when using portable computers, wireless phone, PDA, or other highly mobile communication devices or equipment, the current video or audio visualized using a high quality level can not be entirely a desired system or device W transmission output. 通常,所察觉的缺乏的质量是不能获得传送高质量显示数据所需的高数据速率的结果。 Typically, the perceived lack of quality can not be obtained the desired results of high quality display transfer data at high data rates. 因此,需要一种新的传送机制来增加提供数据的主机装置W及将输出显现给终端用户的客户机显示装置或元件之间的数据通量。 Therefore, a new transfer mechanism is provided to increase the data W and the host device outputs appear to the end user of the client display device or the data throughput between the elements.

[0090]II.环境 [0090] II. Environment

[0091] 图Ia和化中可见一种典型的应用,其中所示的便携式或膝上型计算机100W及无线电话或PDA装置102分别与显示装置104和106W及音频再现系统108和110 -起传送数据。 [0091] seen in FIGS. Ia and of a typical application where a portable or laptop computer 100W and wireless telephone or PDA device 102 are shown in the display device 104 and 106W and audio playback system 108 and 110-- transmitted together data. 无线装置可W当前正在接收数据或者前面已经在存储元件或装置中存储了确定数量的多媒体类型数据,用于稍后显现而由无线装置的终端用户观察和/或龄听。 The wireless device can be currently receiving data or W has already been stored in a memory element or device for determining the number of multimedia type data, for later listening visualized and observed by the end user of the wireless device and / or age. 由于典型的无线装置大多数时间是用于为话音和简单文本通信,因此它具有用于将信息传送至装置102用户的小显示屏和简单音频系统(扬声器)。 Since a typical wireless device is used for most of the time for the voice and simple text communications, it has for communicating information to the user apparatus 102 small display screen and simple audio system (speakers).

[0092]计算机100具有较大的屏幕和仍然不足的外部声音系统,并且仍然不如诸如高清晰度电视或电影屏幕等其他多媒体显示装置。 [0092] Computer 100 has a larger screen and still inadequate external sound system, and still not as good as high definition television or other multimedia display device such as movie screens. 为了说明目的使用了计算机100,然而本发明也可W使用其他类型的处理器、交互式视频游戏或消费者电子装置。 For purposes of illustration the use of the computer 100, but the present invention may also be other types of W processors, interactive video games, or consumer electronics devices. 计算机100可W使用、 但不限于无线调制解调器或用于无线通信的其他内建装置,或者根据需要用电缆或无线链路与送种装置相连。 The computer 100 W can be used, but not limited to a wireless modem or other built-in device for wireless communications, or the necessary cable or a wireless link with the transmitting means associated species.

[0093] 送使显现更复杂或"丰富"的数据并不是有效或令人愉快的经历。 [0093] to send the show a more complex or "rich" data is not effective or enjoyable experience. 因此,工业上发展了其他机制和装置,来将信息显现给终端用户并且提供最低级别的期望享受或肯定的经历。 Therefore, the industrial development of other mechanisms and devices to show the information to end users and provide a minimum level of desired enjoyment or positive experience.

[0094] 如上所述,已经开发了或当前正在开发若干类型的显示装置来将信息显现给装置100的终端用户。 [0094] As described above, it has been developed or several types of display devices are currently being developed to show the information to the end user of the apparatus 100. 例如,一个或多个公司已经开发了可佩带目镜组,为显现视觉显示而在装置用户的眼睛前方投射图像。 For example, one or more companies have developed sets of wearable eyepiece for visual display projected image appears in front of the eyes of the user device. 当被正确放置时,送种装置有效地"投射"虚拟图像,如用户眼睛所观察到的,送远大于提供视觉输出的元件。 When properly placed, seed feeding device effectively "project" a virtual visual output device to provide an image, such as the user's eye observed, much larger than the feed. 也就是说,非常小的投射元件使用户眼睛能"看见"更大比例的图像,可能带有典型的LCD屏幕等等。 That is, a very small projection element allows the user's eye can "see" the image of a greater proportion of the possible with typical LCD screens and the like. 其他显示装置可包括、但不限于, 小LCD屏幕或各种平板显示元件、投射镜和用于在表面上投射图像的显示驱动器,等等。 Other display devices may include, but are not limited to, small LCD screens or various flat panel display elements, projection lenses and display drivers for projecting images on a surface, and the like.

[0095] 也可能有附加元件,与用于将输出显现给另一用户的无线装置102或计算机100 的使用相连或相关,或与反过来将信号传送至别处或存储它们的另一装置相连。 [0095] There may also be additional elements, and for outputting to show another user wireless device 102 or computer 100 connected or associated, or connected to the turn signal is transmitted or stored elsewhere thereof to another device. 例如,数据为了稍后的使用可WW光学形式存储在闪存内,例如使用可写CD媒体或像在磁带记录机或类似装置中郝样在磁性媒体上。 For example, the data for later use in optical form WW stored in the flash memory, for example, a writable CD media or tape recorder or the like in a similar device on the magnetic medium of one kind.

[0096] 此外,许多无线装置和计算机现在具有内建的MP3音乐解码性能W及其他高级声音解码器和系统。 [0096] In addition, many wireless devices and computers now have MP3 music decoding performance W and other advanced sound decoders and systems built. 便携式计算机用CD和DVD回放性能作为一般规则,一些具有用于接收预先记录的音频文件的小的专用闪存阅读器。 Portable computer with CD and DVD playback performance as a general rule, some of which have pre-recorded audio files to receive a small dedicated flash memory readers. 具有送种性能的问题在于,数字音乐文件许诺高度增加的特征丰富经历,但只有当解码和回放过程可W并驾齐驱时。 Has sent kinds of performance problems is that digital music files promise a highly increased feature rich experience, but only if the decoding and playback process can keep pace when W. 对于数字音频文件来说也是一样。 The same is true for digital audio files.

[0097] 为了协助声音再现,图Ia中示出外部扬声器108,也可W伴随着附加元件,譬如子低音扬声器、或者用于前向和后向声音投射的"环绕声"扬声器。 [0097] To assist in sound reproduction, is shown in FIG.

[0098] 如上所述,在任何情况下,当人们期望在一条或多条通信链路112上将高质量或高分辨率的图像数据W及高质量音频信息或数据信号从数据源传送至终端用户时,需要高数据速率。 [0098] As described above, in any case, when one desires to transmit the data from the source in one or more communication links 112 on quality or high resolution image data W and high quality audio information or data signals to the terminal when the user requires a high data rate. 也就是说,由于当前传送机制未达到一般期望的高数据速率,因此传送链路112 无疑是前述数据通信的潜在瓶颈并且限制系统性能。 That is, since current transfer mechanisms generally does not reach the desired high data rate, the transmission link 112 is undoubtedly a potential bottleneck and limit the data communications system performance. 例如,如上所述,为了如1024乘1024 像素的较高图像分辨率,W及每像素24-32比特的色深和30巧S的数据速率,数据速率可W 接近超出336Mbps的速率或更大。 For example, as described above, such as 1024 by 1024 pixels to the high resolution image, W, and 24-32 bits per pixel color depth and data rate of 30 S Coincidentally, W data rate may be close to or greater rate exceeds 336Mbps . 此外,送种图像可W作为多媒体显现的一部分而被显现, 多媒体显现包括音频数据W及处理交互式游戏或通信的潜在附加信号,或者各种命令、控制或信号,进一步增加了质量或数据W及数据速率。 In addition, the image may be sent W species as part of the multimedia show is visualized, the multimedia data including audio visualized W and potentially additional signals dealing with interactive gaming or communications, or various commands, controls, or signals, further increasing the mass or data W and data rate.

[0099] 同样可见,建立数据链路所需的较少电缆或互连意味着与显示器相关的移动装置较易使用,并且更可能由较大的用户基础而采用。 [0099] Also visible, less cable required to establish a data link or interconnect means associated with the display of the mobile device easier to use, and more likely to be adopted by a larger user base. 在通常用多个装置来建立完全音频-视觉经历时送尤其正确,并且当显示器和音频输出装置的质量水平增加时更加正确。 In a typical fully established by a plurality of audio devices - especially true when sending visual experience, and more precisely when increasing the quality level of the displays and audio output devices.

[0100] 不幸的是,较高的数据速率超出当前可用于传送数据的技术。 [0100] Unfortunately, the higher data rates exceed current technology available for transferring data. 需要一种技术,用于在显现元件和数据源之间的数据传送链路或通信路径上W较高的速率传送数据,它允许W 持续的低(较低)的功率、轻量、W及尽可能简单和经济的电缆结构。 Need for a technique for the data transfer link or communication path between the source and the data elements visualized higher data rate transmission W, W which allows sustained low (er) power, light weight, and W as simple and economical a cabling structure. 申请人已开发了一种新的技术,或方法和装置,来达到送些及其它目标,W允许移动站的阵列、便携式或甚至固定位置装置W非常高的数据速率将数据传送至期望的显示器、微显示器或音频传送元件, 而保持期望的低功耗和复杂度。 Applicants have developed a new technique, or method and apparatus, to achieve these and other objects to send, W allow the array to the mobile station, portable, or even fixed location W means a very high data rate to transfer data to desired displays , micro-displays, or audio transfer elements, while maintaining a desired low power consumption, and complexity.

[0111] 在送种接口中,主机通过将特殊指令或分组类型发送至客户机而允许在主机处接收来自客户机(反向话务或链路)的通信数据,客户机允许其在特定持续时间接管总线并且将数据作为反向分组发送至主机。 [0111] In the transmission interface types, the host by sending a special command or packet type to the client to allow the communication data received from the client (reverse traffic or link) at the host, allowing it to continue in the client specific time takes over the bus and sends the data to the host as reverse packets. 送在图3中得到说明,其中使用被称为封装分组(下面讨论)的分组类型来提供传输链路上反向分组的传输,从而创建反向链路。 In the feed obtained illustrated in Figure 3, wherein the packet type using the called encapsulation packet (discussed below) to provide a packet transmission on the reverse transmission link, creating the reverse link. 为轮询数据的显示而分配给主机的时间间隔由主机预先确定并且基于各专口应用的要求。 Polling data display time allocated to the host by the host and the predetermined interval based on the required application the tertiary port. 送种类型的半双工双向数据传输在USB端口不可用于来自客户机的信息或数据传输时尤其有利。 Species particularly advantageous when the feed type of half-duplex bidirectional data transfer in the USB port is not available for transfer of information or data from the client.

[0112] 类型U接口传输适用于膝上型电脑和台式机应用的信号,其中USB接口得到大量主板或其它硬件的广泛支持,并由操作系统软件支持。 [0112] Type U interface to transmit a signal suitable for laptop and desktop applications where a USB interface is widely supported a large number of motherboards or other hardware, software supported by the operating system. 添加的USB接口的使用能够使用"即插即用"特征和简易应用配置。 Using a USB interface can be added using the "plug and play" features and easy application configuration.

[0113] USB接口是现代个人计算机设备非常广泛使用的标准,且USB接口的细节及其操作在本领域中是众所周知的,因此在此不再说明。 [0113] USB interface is a standard modern personal computer equipment is very widely used, and the USB interface details of their operation are well known in the art, and therefore will not be described here. 对于USB接口而言,主机和显示器之间的通信遵从通用串行总线规范,修订版2. 0。 For the USB interface, communication between the host and the display of a Universal Serial Bus Specification, Revision 2.0. 在使用类型U接口的应用中,其中USB是主要的信令信道且可能是话音返回信道,任选地主机可W通过M孤I串行数据信号轮询客户机。 In applications using the Type U interface where USB is the primary signaling channel and possibly a voice return channel, the host may optionally through W I M lone serial data signal to poll the client.

[0114] 为了支持完全运动视频,皿TV类型或类似高分辨率性能的高性能显示器要求约为1. 5抓S速率的数据流。 [0114] In order to support full-motion video, TV dish type or similar high-performance displays require high resolution performance of approximately 1.5 S catch rate data streams. 类型-n接口通过并行发送2比特来支持高数据速率,类型-III接口通过并行发送4比特来支持,而类型-IV接口并行传送8比特。 -N type through a parallel interface supports high data rate transmission bit 2, supported by the interface type -III transmitting 4 bits in parallel, and the Type 8-bit parallel transfer interfaces -IV. 由M孤I使用的协议允许各类型-1、II、III或IV主机通过协商可被使用的最高数据速率而与任何类型-1、II、III 或IV客户机进行通信。 I used by a lone M protocol allows each Type-1, the highest data rate II, III or IV may be negotiated by the host and used to communicate with any Type-1, II, III or IV client. 可被称为最少可能装置的性能或可用特征被用来设置链路的性能。 Performance or available features may be referred to as the least possible means is used to set the performance of the link. 作为规则,即使对于主机和客户机都能使用类型-II、类型-III或类型-IV接口的系统来说,两者都作为类型-I接口而开始工作。 As a rule, even if -II type can be used for host and client, system type -III or -IV interface type, the type -I as both an interface and start working. 然后,主机确定目标客户机或显示器的性能,并且将切换或重新配置操作协商为或类型-II、类型-III,或类型-IV模式,送对于特定应用是适当的。 The host then determines the performance of the target client or display, and the handover or reconfiguration operation type negotiation or -II, -III type, model or type -IV, send appropriate for a particular application.

[0115] 主机一般可能使用适当的链路层协议(下面进一步讨论)并且在任何时候降低为或在此重新配置操作至较慢的模式W节约功率,或者提高到较快的模式W支持较高速度的传输,如对于较高分辨率显示内容而言。 [0115] Typically, the host may use an appropriate link-layer protocol (discussed further below) and this is reduced to or reconfiguration operation to a slower mode to save power W at any time, or up to a faster mode to support higher W transmission speed, such as for higher resolution display content concerned. 例如,当显示系统从诸如电池的功率源切换至AC 电源时,或者当显示媒体的源切换至较低或较高的分辨率格式时,或者送些或其它条件或事件的组合可被视作改变显示或数据传输模式的基础时,主机可W改变显示模式。 For example, when the display system switches from a power source such as a battery to AC power, or when the display is switched to the source media lower or higher resolution format, or a combination of these or other feed conditions or events may be considered to change the display or the underlying data transmission mode, the host can change the display mode W.

[0122] 虽然数据可W在MDDLData对上的前向和反向方向上流动,即它是双向传输通道,然而主机是数据链路的主人或控制者。 [0122] Although the data may be on MDDLData W of the flow in the forward and reverse directions, i.e. it is a bidirectional transmission path, however, the host is the master or controller of the data link. 为了使噪声抗扰性最大,M孤LDataO和M孤1_ S忧信号通道W差分模式工作。 In order to make the maximum noise immunity, M and M lone lone LDataO 1_ S worry differential signal channels W mode. 送些线上信号的数据速率由主机发出的时钟速率确定,并且在约为化bps到400Mbps或更大的范围上是可变的。 These signal lines transmitting a data rate clock rate determined by the master, and the bps of about 400Mbps to or greater extent is variable.

[0152] 一群分组被包含在被称为子顿的信号元件或结构内,一群子顿被包含在被称为媒体顿的信号元件或结构内。 [0152] a group of packets are contained within signal elements or structures referred to as sub Dayton, Dayton sub-group are contained within signal elements or structures referred to as media Dayton. 子顿包含一个或多个分组,送取决于它们相应的大小和数据传输用途,媒体顿必须包含多一个的子顿。 Sub Dayton comprising one or more packets, depending on their respective size of the transmission and a data transmission purposes, Dayton medium must contain one more sub Dayton. 由本发明使用的协议提供的最大子顿在232-1即4, 294, 967, 295字节的数量级上,于是最大媒体顿大小变为在21S-1即65, 535字节的数量级上。 The maximum sub Dayton provided by the protocol used in the present invention i.e. 4 232-1, 294, 967, 295 the number of byte-level, then the maximum media size becomes Dayton 21S-1 in the number of 65, 535-byte level.

[0154] 一般而言,当显示全运动视频时,显示屏每媒体顿被更新一次。 [0154] In general, when displaying full-motion video, the display is updated once per media Dayton. 显示器顿速率与媒体顿速率相同。 Dayton Dayton media display rate same rate. 链路协议支持整个显示器上的全运动视频,或者由静态图像包围的全运动视频内容的仅仅一个小区域,送取决于期望的应用。 Link protocol supports full-motion video over an entire display, or surrounded by a static image only a small region of full-motion video content, depending on the desired application sent. 在某些低功率移动应用中,譬如查看Web网页或电子邮件,显示屏仅需偶尔被更新。 In some low-power mobile applications, such as viewing a Web page or e-mail, the display is updated only occasionally. 在郝些情况下,发射单个子顿然后关闭链路W使功耗最小是有利的。 In some cases Hao, and then transmit a single sub-close link Dayton W advantageous to minimize power consumption. 接口也支持诸如立体显示送样的效应,并且处理图形的基元。 Interface also supports stereoscopic display, such as a send-like effect, and the process graphics primitives.

[0160]图6中说明了实现用于分组传输的前向链路通信的信号协议或顿结构。 In [0160] FIG. 6 illustrates an implementation of a signaling protocol packet before transmission to the communication link or a draft structure. 如图6所示,信息或数字数据被组合成被称为分组的元素。 6, information or digital data is combined into an element is referred to as a packet. 多个分组依次组合在一起W形成"子顿", 多个子顿依次组合在一起W形成"媒体"顿。 Grouping together a plurality of successively formed W "child Dayton", a plurality of sub Dayton W are sequentially combined to form a "media" Dayton. 为了控制顿格式和子顿的传输,各子顿用特别预定义的分组开始,被称为子顿报头分组(SHP)。 In order to control and sub Dayton Dayton transmission format, with each sub Dayton particular predefined start packet, referred to as sub Dayton Header Packet (SHP).

[0161] 主机装置选择要为给定传输使用的数据速率。 [0161] The host device selects the transmission to be used for a given data rate. 该速率可W由主机装置根据主机的最大传输性能或由主机从源检取的数据、W及显示器或数据被发送至的其他装置的最大能力而动态地改变。 This rate can be changed dynamically W by the host device based on the maximum capacity or the maximum transmission performance of the host of other devices, W, and the display data is sent by the host or data source to the retrieved from.

[0162] 受信客户机装置被设计为,或者能够与WDDI-起工作,或者发明的信号协议能由主机查询W确定它能使用的最大、或当前最大的数据传输速率,或者可能使用的缺省较低最小速率,W及所支持的可用数据类型和特性。 [0162] trusted client device is designed or can WDDI- from work, or the invention can be determined by the host signal protocol query W can use the maximum, or current maximum, data transfer rate, may be used or the default lower minimum rate, W, and supported by the available data types and characteristics. 如下进一步所述,该信息可W用显示性能分组值(P)来传输。 As further described below, the display performance information packet with the value of W (P) is transmitted. 客户机显示装置能够W预先选择的最小数据速率或者在最小数据速率范围内用接口与其他装置传输数据或者通信,主机将用该范围内的数据速率来进行询问W确定客户机装置的全部性能。 The client display device is capable W minimum data rate preselected or or communication, host data rate within this range to perform query W ascertain the full performance of the client device using an interface with other devices to transmit data within a minimum data rate range.

[0163] 其他定义显示器的位图性质和视频顿速率性能的状态信息可W在状态分组中被传送至主机,使得主机能将该接口或配置为高效的或配置为实践上最佳,或者在任何系统限制内所期望。 [0163] FIG nature and status information bit rate performance of Dayton video display may be other definitions W transferred to the host in status packet, so that the host can configure the interface or to configure efficient or best practice, or We expect any system constraints.

[0164] 当前子顿中不存在要被传送的数据分组时,或者当主机不能W与为前向链路选定的数据传输速率保持同步的足够速率进行传输时,主机发送填充符分组。 [0164] Benton current sub data does not exist in the packet to be transmitted, or when the host can not be selected as W and the front link data transmission rate to a rate sufficient to maintain the synchronization for transmission, the host sends filler packets. 由于各子顿用子顿报头分组开头,因此先前子顿的末尾包含正好填充先前子顿的一个分组(最有可能是填充符分组)。 Since the beginning of the sub-header packet Dayton Dayton with each of the sub, so the end of the previous sub Dayton comprises exactly fills the previous sub-packet Raton (most likely a filler packet). 在缺乏承受每集分组的数据空间的情况下,填充符分组最可能是子顿中的最后一个分组,或者处于下一个前一子顿的末尾并且在子顿报头分组之前。 In the absence of a data packet receiving space of each episode, a filler packet will most likely be the last sub-packet Dayton, or at the end of the previous sub Dayton and before a next sub-packet header Dayton. 主机装置中控制操作的任务是确保子顿中有足够的剩余空间,用于在该子顿内发送每个分组。 Task control operations in a host device is to ensure that there is a sub Dayton enough free space, for transmitting each sub-packet within the Dayton. 与此同时,一旦主机装置启动数据分组的发送,主机必须能成功地完成顿内该尺寸的分组,而不招致数据的欠载运行状态。 At the same time, once a host device initiates the sending of data packets, the host must be able to successfully complete a packet of that size within Dayton, without incurring a data under run condition.

[0165] 在本发明实施例的一个方面,子顿传输具有两种模式。 [0165] In one aspect of the embodiment of the present invention, the sub Dayton transmission has two modes. 一个模式是用于发射实况视频和音频流的周期性子顿模式。 One mode is a periodic sub-pattern for transmitting Dayton live video and audio streams. 在该模式中,子顿长度被定义为非零。 In this mode, the sub-length is defined as zero Dayton. 第二个模式是异步或非周期性模式,其中顿用于仅在新信息可用时将位图数据提供给显示装置。 The second mode is an asynchronous or non-periodic mode in which only Dayton for providing bit map data to the display device when new information is available. 该模式通过在子顿报头分组中将子顿长度设为零而定义。 This mode will be the length of the sub-sub Dayton Dayton packet header is set to zero is defined. 当使用周期性模式时,子顿分组接收可W 在显示器已经与前向链路顿结构同步时开始。 When using the periodic mode, sub Dayton W can display received packet has been started and synchronized to the link structure before meal. 送对应于下面参考图49讨论的状态图定义的"同步中"状态。 Send a state corresponding to FIG. 49 discussed below with reference to "IN-SYNC" state defined FIG. 在异步非周期性子顿模式中,接收在接收到第一子顿报头分组之后开始。 In the asynchronous non-periodic sub Dayton mode begins after receiving the received first sub-header packet meal.

[0177]子顿报头分组是每一个子顿的第一个分组,并且具有如图8所述的基本结构。 [0177] Sub Dayton packet header is the first packet of every sub Dayton, and has a basic structure in FIG. 8. 如图8所示,送种类型的分组被构造成具有分组长度、分组类型、唯一字、子顿长度、协议版本、子顿计数和媒体顿计数字段,一般顺序如此。 8, the send packet types is structured to have Packet Length, Packet Type, Unique Word, Sub Dayton length, protocol version, and counting the media sub Dayton Dayton count field, so the general order. 送种类型的分组一般被标识为类型255(Oxff十六进制)分组并且使用17字节的预先选定的固定长度。 Send packets types are typically type 255 (Oxff hexadecimal) packet and uses a pre-selected 17 bytes of fixed length identifier.

[0178]虽然分组类型字段使用1字节值,然而唯一字字段使用3字节值。 [0178] While the Packet Type field uses 1 byte value, the Unique Word field but using 3 byte value. 送两个字段的4字节组合一起形成具有良好自相关的32比特唯一字。 Forming the 32-bit unique word with good autocorrelation send two fields with a combination of 4 bytes. 实际唯一字是0x005a3bff,其中较低的8比特作为分组类型先被发送,而最高的24比特之后被发送。 The actual unique word is 0x005a3bff, wherein the lower 8 bits are transmitted first as the Packet Type, is transmitted after the highest 24 bits.

[0179]子顿长度字段包含指定每子顿字节数的4字节信息。 [0179] Sub Raton length field contains a number of bytes per sub Dayton 4 bytes of information. 该字段的长度可W被设为零,表示在链路被关闭为空闲状态前主机将只发送一个子顿。 W length of the field may be set to zero, the host will transmit only it represents a sub-link is closed before the meal to the idle state. 当从一个子顿转移到下一个子顿时,该字段中的值可在运行中"动态变化。为了在用于提供同步数据流的同步脉冲中作出较小定时调节,该性能是有用的。如果子顿报头分组的CRC无效,则链路控制器应该使用先前已知良好的子顿报头分组的子顿长度来估计当前子顿的长度。 When the transfer from one to the next sub-sub Dayton suddenly, the value in this field may be "dynamic changes in operation. To provide a synchronization pulse for synchronizing the data stream at the timing adjustment made smaller, the performance is useful if Dayton CRC sub-header of the packet is invalid, then the link controller should use sub-length Dayton Dayton previously known good sub-header packet to estimate the length of the current sub-Dayton.

[0180] 协议版本字段包含2字节,指定由主机使用的协议版本。 [0180] The Protocol Version field contains 2 bytes that specify the protocol version used by the host. 协议版本字段被设为"0",将协议的第一或当前版本指定为使用中。 Protocol Version field is set to "0", the first or the current version of the protocol specified for the use. 该值将随着新版本的创建而随时间改变。 This value will change over time as new versions are created. 子顿计数字段包含2字节,指定表示自媒体顿开始时已被发送的子顿数的序列号。 Dayton sub Count field contains 2 bytes, specifies the sequence number represents the number of sub-media self Dayton Dayton start has been transmitted. 媒体顿的第一子顿具有值为零的子顿计数。 Dayton Dayton sub medium having a first sub-meal count value of zero. 媒体顿的最后一子顿的值为n-1,其中n每媒体顿的子顿数。 The final media sub Dayton Dayton value n-1, n where the number of sub tons per media Dayton. 注意到,如果子顿长度被设为零(表示非周期性子顿),则子顿计数也必须被设为零。 Note that if the length is set to zero sub Dayton (indicating a non-periodic sub Dayton), the sub Dayton count is also set to zero.

[0181]媒体顿计数字段包含3字节,指定一个序列号,表示自当前被传输的媒体项或数据开始W来已被发送的媒体顿数目。 [0181] Media Raton Count field contains 3 bytes, specifies a sequence number indicating the media items from the data currently being transmitted or the number of the media began to Dayton W has been transmitted. 媒体项的第一媒体顿的媒体顿计数为零。 A first media media media items Dayton Dayton count is zero. 媒体顿计数刚好在各媒体顿的第一子顿之前增一,并且在使用了最大媒体顿计数(媒体顿数目22 4-1 = 16, 777, 215)之后变回零。 Media Dayton Count increments just prior to the first sub-meal by the media a Dayton, and the largest media used in Dayton count (the number of media Dayton 224-1 = 16, 777, 215) then back to zero. 媒体顿计数值一般可由主机在任何时间重置W满足终端程序的需要。 Usually Dayton media by the host to reset the count value of W at any time to meet the needs of the terminal program. . 刪2.填布符外纽 2.

[0183] 填充符分组是当前向或反向链路上没有其他可被发送的信息时被发送至客户机装置或从客户机装置被发出的分组。 [0183] A filler packet is currently being transmitted when no other information can be transmitted to the client device or the packet is sent from the client device on the forward or reverse link. 推荐填充符分组具有最小长度W便允许需要发送其他分组时的最大灵活性。 It recommended that filler packets have a minimum length W maximum flexibility in sending other packets will be allowed when needed. 在子顿或反向链路封装分组(见下)的终端处,链路控制器设定填充符分组的大小W便填充剩余空间W保持分组整体性。 At the terminal or the sub-Raton Reverse Link Encapsulation packet (see below), a link controller sets the size of the filler packet to fill the remaining space will be W W held packet integrity.

[0184]图9示出填充符分组的格式和内容。 [0184] FIG. 9 illustrates the format and contents of a Filler Packet. 如图9所示,送种类型的分组的结构为具有分组长度、分组类型、填充符字节、W及CRC字段。 9, the structure types of packets to send to have Packet Length, Packet Type, Filler Bytes, W, and CRC fields. 送种类型的分组一般被标识为类型0,它在1字节的类型字段中表示。 Species type of packet is generally sent to be identified as a Type 0, which indicates the 1-byte type field. 填充符字节字段内的比特或字节包括可变数量的全零比特, 允许填充符分组成为期望的长度。 Bits or bytes in the Filler Bytes field comprise a variable number of all zero bit, allow the filler packet to be the desired length. 最小的填充符分组在该字段中不包含任何字节。 The smallest filler packet contains no bytes in this field. 也就是说,该分组仅由分组长度、分组类型和CRC组成,并且使用3字节的预先选定的固定长度。 That is, only the packet from the Packet Length, Packet Type, and CRC composition, and the use of 3 bytes preselected fixed length. 阳1财3.视颇流分纽 3.

[0187] 上述常见的顿概念是使音频缓冲大小最小并且减少等待时间的有效方式。 [0187] The common concept is that the audio buffers Dayton minimum size and effective way to reduce latency. 然而, 对于视频数据而言,可能需要在媒体顿内的多个视频流分组间扩展一个视频顿的像素。 However, for video data, a video inter-packet extension Dayton pixel in the plurality of video streams may need Dayton media. 同样很可能的是,单个视频流分组内的像素不会正好对应于显示器上完整的矩形窗。 It is likely that the same pixels within a single Video Stream Packet will not exactly correspond to a perfect rectangular window on the display. 对于示例性每砂30顿的视频顿速率而言,每砂有300个子顿,送导致每媒体顿10个子顿。 For example each of 30 tons of sand Dayton video rates, the sand 300 per sub Dayton, leading to send media every 10 sub Dayton Dayton. 如果每顿内有480行像素,则各子顿内的各视频流分组将包含48行像素。 If there are 480 rows of pixels within every meal, then each Video Stream Packet in each sub-meal containing 48 rows of pixels. 在其他情况下,视频流分组可能不包含整数行的像素。 In other cases, the Video Stream Packet might not contain an integer pixel rows. 送对于其它视频顿大小也是正确的,其中每媒体顿的子顿数不均匀地分成每视频顿的行数(也称为视频行)。 For other video feed meal size it is correct, wherein the number of sub tons per media Dayton unevenly divided Dayton number of lines per video (also known as video lines). 即使各视频流分组可能不包含整数行的像素,然而它必须包含整数个像素。 Even if each of the Video Stream Packet might not contain an integer pixel row, but it must contain an integer number of pixels. 如果像素大于每像素一字节,或者如果它们为图12 所示的分组格式,郝么送将是重要的。 If the pixel is greater than one byte per pixel, or if they are in the packet format shown in FIG. 12, Hao send it will be important.

[018引图Ila-Ild示出实现上述视频数据描述符字段的操作所使用的格式和内容。 [Primer 018 shown in FIG Ila-Ild format and contents to achieve the above-described operation of the Video Data Descriptor field used. 图Ila-Ild中,视频数据格式描述符字段包含2字节,其形式为16比特的无符号整数,指定了当前分组中当前流内像素数据中各像素的格式。 FIG Ila-Ild, the Video Data Format Descriptor field contains 2 bytes in the form of 16-bit unsigned integer that specifies the packet flow in the current pixel data of each pixel in the current format. 不同流(由流ID字段指明)可能使用不同的像素数据格式,即,在视频数据格式描述符内使用不同值,同样,任何流都可能在运行中改变其数据格式。 Different streams (indicated by the Stream ID field) may use different pixel data formats, that is, with different values ​​in the Video Data Format Descriptor, and similarly, any stream may change its data format operation. 视频数据格式描述符定义了当前分组的像素格式,仅此不意味着特定视频流使用期限内会继续使用恒定格式。 Video Data Format Descriptor defines the pixel format for the current packet only does this mean that a constant format will continue to be used within a particular video stream life.

[0189]图Ila-Ild说明了怎样编码视频数据格式描述符。 [0189] FIG Ila-Ild illustrates how the Video Data Format Descriptor encoded. 如送些图中所用,如图Ila所示,当比特[15 : 13]等于"000"时,视频数据包括一个阵列的单色像素,其中每像素的比特数由视频数据格式描述符字的位3至0所定义。 As used in these figures to send, as Ila, when bits [15:13] is "000", a video data includes an array of monochrome pixels where the number of bits per pixel descriptor word by the Video Data Format bits 3 through 0 defined above. 如图1化所示,当比特[15 : 13]等于"001"时,视频数据包括一个阵列的彩色像素,其中每像素都指定色图中的一个颜色。 Of 1, when bits [15:13] is equal to "001", the video data comprising a color pixel array in which each pixel is assigned a color of the color chart. 在送种情况下,视频数据格式描述符字的位5至0定义了每像素的比特数,位11至6被设为等于零。 In the kind of feed, the bit Video Data Format Descriptor word define the number of 5-0 bits per pixel, and bits 11 through 6 are set to zero. 如图Ilc所示,当比特[15 :切等于"010"时,视频数据包括一个阵列的彩色像素, 其中红色的每像素比特数由位11至8所定义,绿色的每像素比特数由位7至4所定义,藍色的每像素比特数由位3至0所定义。 FIG Ilc, when bits [15: Cut equal to "010", the video data comprising a color pixel array, wherein the number of bits per pixel of red bits 11-8 defined by the number of bits per pixel of green by bits 7-4 is defined, the number of bits per pixel of blue is defined by bits 3-0. 在送种情况下,总的每像素比特数是红色、绿色和藍色所用的比特数之和。 In the kind of feed, the total number of bits per pixel of red, green, and blue are used and the number of bits.

[0190] 然而,如图Ild所示,当比特[15 :切等于"Oir咐,视频数据包括一个阵列的视频数据,格式为4:2:2,带有亮度和色度信息,其中亮度(Y)的每像素比特数由位11至8定义,化分量的比特数由位7至4定义,而Cb分量的比特数由位3至0定义。每像素的总比特数是红色、绿色和藍色所用的比特数之和。化和CbW发送Y的速率的一半被发送。此外, 该分组的像素数据部分中的视频采样如下组织;Y。,化。,Cb。,Yw,Yw2,化…,CtwYw3, ...其中Cr。和Cbn与Yn和Y相关,Cr…和Cbn。与Yn巧和Y…相关,依此类推。如果当前流的一行中有奇数个像素狂右边缘-X左边缘+1),则对应于每行中最后一个像素的Cb值后面将跟着下一行的第一个像素的Y值。 [0190] However, as shown in FIG Ild, when bits [15: Cut equal "Oir commanded, an array of video data includes a video data format is 4: 2: 2, with luminance and chrominance information, wherein the luminance ( Y) the number of bits per pixel is defined by bits 11 through 8, of the components of the number of bits defined by bits 7 through 4, and the number of bits of the Cb component is defined by bits 3 through 0. the total number of bits per pixel of red, green, and blue used the number of bits and a half and CbW send the Y rate is transmitted addition, the pixel data portion of the packet of video samples is organized as follows;. Y, of, Cb, Yw, Yw2, of... ..., CtwYw3, ... which of Cr. Cbn and associated with Yn and Y, Cr ... and Cbn. Y ... and Yn clever and related, and so on. If there are an odd number of pixels in the line of the current flow wild right edge -X left edge +1), then the Cb value corresponding to the back of the last row in each pixel will be followed by a first pixel of the next row of the Y value.

[0191] 对于图中所示的所有四种格式而言,被指明为"P"的位12指定该像素数据采样是否是分组的、或字节对齐的像素数据。 [0191] For all four formats shown in the figures, the designated pixel is indicated whether the packet is a data sample of "P" bits 12, or byte-aligned pixel data. 该字段中"0"值表示像素数据字段中每个像素内的每个像素和每个颜色都与MDDI接口字节边界字节对齐。 The field "0" represents a pixel value of each pixel in the data fields and each color within each pixel aligned with an MDDI interface byte boundary bytes. "1"值表示像素数据中每个像素和每个像素内的每个颜色都相对于像素内的前一像素或颜色而被打包而不留下未使用的比特。 "1" represents a pixel value of each pixel and the data of each color within each pixel with respect to the previous pixel or color within a pixel to be packed without leaving unused bits.

[0192]特定显示窗的第一视频流分组内的第一像素会进入由X偏移和Y偏移定义的流窗口的左上角,而下一个接收到的像素被放在同一行内的下一像素位置,依此类推。 [0192] The first pixel in the first video stream packet of a particular display window will enter the top left corner of the stream window defined by an X and Y offsets, and the next pixel received is placed in the same row of the next pixel location, and so on. 为了便于该操作,显示器使"下一像素行和列"计数器保持与每个活动视频流ID相关。 To facilitate this operation, the display so that the "next pixel row and column" counter keeps ID associated with each active video stream. 阳19引4.音颇流外纽 19 male outer lead 4.

[0203] 数据用反向链路封装分组在反向上被传输。 [0203] Reverse Link Encapsulation Packet data is transmitted on the reverse. 前向链路分组被发送,MDDI链路操作(传输方向)在该分组的中间被改变或转向W便可W在反向上发送分组。 Link packets to be transmitted before, MDDI link operation (transfer direction) is changed or turned W W can transmit packets in the reverse direction in the middle of the packet. 图17说明了反向链路封装分组的格式。 17 illustrates the format of a Reverse Link Encapsulation Packet. 如图17所示,送种类型的分组结构具有分组长度、分组类型、反向链路标志、转向长度、参数CRC、转向1、反向数据分组、W及转向2。 17, the send packet structure types have Packet Length, Packet Type, Reverse Link Flags, Turn-Around Length, Parameter CRC, Turn-Around 1, Reverse Data Packets, W 2 and steering. 送种类型的分组一般被标识为类型65分组。 Species send packets types are generally identified as a Type 65 packet.

[0204] M孤I链路控制器在发送反向链路封装分组时W特殊的方式工作。 [0204] M I link controller solitary work W special manner while sending a Reverse Link Encapsulation Packet. M孤接口具有一个总是由主机激励的选通信号。 M lone interface has a strobe signal is always excited by the host. 主机表现得好像它正在为反向链路封装分组的转向和反向数据分组部分的每个比特发送一个零。 The host behaves as if it were a steering and reverse each bit of the Reverse Data Packets portions of the transmission of a zero-Link Encapsulation Packet. 在两段转向时间期间和为反向数据分组分配的时间期间,主机在每一个比特边界转换M孤LStrobe信号。 During the period of time and two steering Reverse Data Packets assigned LStrobe isolated host conversion signal M at each bit boundary. (送就相当于它在发送全零数据的行为。)主机在由转向1指定的时间段禁用其M孤I数据信号线路驱动器,而客户机在由转向2字段指定的时间段之后的驱动器再起动字段期间再起动其线路驱动器。 (Send equivalent it were sending all zeroes data behavior.) The host disables its M lone I data signal line drivers by turning a specified time period 1, and the client after a specified by the Turn Around 2 field period of the drive and then restart its line drivers during the starting field. 显示器读取转向长度参数并且在转向1字段的最后一比特后立即将数据信号驱向主机。 Display reads the Turn-Length parameter and drives the data signal immediately to the host 1 in the steering field is the last bits. 显示器使用分组长度和转向长度参数来得知可用于将分组发送至主机的时间长度。 Display uses the Packet Length and Turn-Around Length parameters to know may be used to send the packet to the length of time the host. 在没有发送至主机的数据时,客户机可W发送填充符分组或者将数据线激励至零状态。 When data is not sent to the host, the client may send filler packets or W data lines to a zero state excited. 如果数据线被激励至零,则主机将其理解为具有零长度(不是有效的长度)的分组,并且主机在当前反向链路封装分组的持续期间不再接收任何来自客户机的分组。 If the data lines are excited to zero, the host will be understood as a packet with a zero length (not a valid length) and the host does not accept any more packets from the client for the duration of the current Reverse Link Encapsulation Packet.

[0205] 显示器在转向2字段开始前的至少一个反向链路时钟周期将M孤I数据线激励至零电平。 [0205] Display at least one reverse link clock period before the start of the Turn Around 2 field Solitary I M data lines to the zero level excitation. 送使数据线在转向2时间段内保持在确定的状态。 Sending the data line 2 in the period of holding the steering state determined. 如果客户机不再有待发送的分组,它甚至能在将它们激励至零电平之后禁用数据线,送是由于休眠偏置电阻(他处讨论) 使数据线在反向数据分组字段的其余时间保持在零电平。 If the client no longer packet to be transmitted, it can even disable the data lines after they have been excited to a zero level, because transmission dormant bias resistor (discussed elsewhere) in the remaining time of the data line of the Reverse Data Packets field remains at zero level.

[0206]为了通知主机将数据发回主机时显示器在反向链路封装分组中所需的字节数,可W使用显示请求和状态分组值isplayRequestandStatusPacket)的反向链路请求字段。 [0206] In order to notify the host when the number of bytes the display data back to the host in the Reverse Link Encapsulation desired packets, W can be displayed using Request and Status Packet value isplayRequestandStatusPacket) Reverse Link Request field. 主机企图通过在反向链路封装分组中分配至少该数量的字节而允许该请求。 Host attempts by allocating at least that number of bytes in the Reverse Link Encapsulation Packet to allow the request. 主机可W 在子顿中发送多于一个反向链路封装分组。 Dayton W in the sub host may send more than one Reverse Link Encapsulation Packet. 显示器可W在几乎任何时候发送显示请求和状态分组,主机将反向链路请求参数解释为一个子顿中请求的总字节数。 The display may send W Display Request and Status Packet, the host will be virtually at any time, reverse Link Request parameter as the total number of bytes to be construed as a sub Dayton requested. 阳207] 9.思示巧能分纽 Male 207] 9.

[0262] 在本发明的示例性实施例中,反向不归零(NR幻格式的数据用数据选通信号或DATA-STB格式来编码,送允许时钟信息被嵌入在数据和选通信号内。时钟可W无须复杂的锁相环电路而被恢复。数据在双向差分链路上被传送,一般用有线电缆来实现,然而如前所述,也可W使用其它导线、印刷电线或传输元件。选通信号(STB)在仅由主机驱动的单向链路上传送。选通信号在紧接的状态0或1时反转其值(0或1),送在数据线或信号上也是一样。 [0262] In an exemplary embodiment of the present invention, NRZI (NR Magic data format or data strobe signal DATA-STB encoding format, allowing the clock to send the data information is embedded in the signal and the gate the clock may be W without complex phase lock loop circuit is restored data is transmitted on a bi-directional differential link, generally implemented using a wired cable, but as described above, W may be used other conductors, printed wires, or transfer elements . strobe signal (STB) is transmitted on a unidirectional link is driven only by the host. strobe inverted value (0 or 1) state immediately 0 or 1, or send a signal on the data line is same.

[026引图40用图表示出怎样用DATA-STB编码发送诸如比特"1110001011"送样的数据序列的示例。 [FIG lead 026 is shown in FIG. 40 is an example of how bits such as "1110001011" to send samples of transmission data sequence DATA-STB encoding. 在图40中,DATA信号4002在信号时序图的顶线上示出,STB信号4004在第二根线上示出,各适当地时间对齐(公共起始点)。 In FIG 40, DATA signal 4002 is shown on the top line of a signal timing chart, the STB signal 4004 is shown on a second wire pair, the fitness of local time alignment (common starting point). 随着时间的推移,当DATA线4002 (信号) 上发生状态变化时,STB线4004 (信号)保持前面的状态,因此,DATA信号的第一"1"状态与STB信号的起始值第一"0"状态相关。 Over time, when the state change on the DATA line 4002 (signal), STB line 4004 (signal) held in front of the state, the first start value "1" state for the STB signal and a first signal DATA "0" state-related. 然而,如果或当DATA信号的状态、电平未变化时, 贝IJSTB信号切换到相对的状态即前例中的"1",正如图40中DATA正提供另一"1"值的情况。 However, if or when the state of the DATA signal, when the level has not changed, shellfish IJSTB signal is switched to the opposite state in the previous example, ie "1", as in FIG. 40 where the DATA is providing another case value "1." 也就是说,DATA和STB间每比特周期总是有一个并且只有一个变换。 That is, between DATA and STB every bit period there is always one and only one transformation. 因此,当DATA信号保持在"1"时,STB信号送次再次转变为"0"并且当DATA信号电平改变为"0"时保持该电平或值。 Thus, when the DATA signal stays at '1', the STB signal is sent once again to "0" and maintains that level or value when the DATA signal changes level to "0." 当DATA信号保持在"1"时,STB信号切换至相反状态,即前例中的"1 ",当DATA 信号改变或者保持电平或值时依此类推。 When the DATA signal stays at '1', the STB signal is switched to the opposite state, i.e., in the previous example, "1", and so on as the DATA signal changes or holds the level or value.

[0264] 在接收到送些信号之后,在DATA和STB信号上进行异或狂OR)操作W产生时钟信号4006,送在期望数据和选通信号的相对比较的时序图底部示出。 [0264] After receiving the send some signal, DATA and STB signals at the Great XOR OR) operation of generating a clock signal 4006 W, at a desired timing diagram of sending data and strobe signals shown at the bottom of the relatively. 图41示出一个电路系统示例,用于从主机处的输入数据产生DATA和STB输出或信号,然后从客户机处的DATA和STB信号中恢复或重新捕获该数据。 41 shows one example circuitry for generating the DATA and STB outputs or signals from input data at the host, and then recovering from the DATA and STB signals at the client, or recapture the data.

[026引在图41中,发射部分400用于产生并在中间信号通道4102上发送原始DATA和STB信号,而接收部分4120用于接收信号并恢复数据。 [026 introduced in FIG. 41, the transmitting portion 400 for generating and transmitting the original DATA and STB signals at the intermediate signal path 4102, while a reception portion 4120 for receiving the signals and recover the data. 如图41所示,为了将数据从主机传送至客户机,DATA信号与用于触发电路的时钟信号一起被输入到两个D型触发器电路元件4104 和4106。 As shown, in order to transfer data from a host to a client, DATA and clock signals for the flip-flop circuit 41 is input to two D-type flip-flop with the circuit elements 4104 and 4106. 然后,两个触发器电路输出(曲用两个差分线路驱动器4108和4110(电压模式) 分别分裂成差分对信号M孤I_DataO+、M孤LDataO-W及M孤I_S忧+、M孤I_S忧-。H输入端异或非狂NOR) 口、电路或逻辑元件4112被连接,用于接收DATA和两个触发器的输出,并且产生提供第二触发器的数据输入的一个输出,送又产生M孤I_S忧+、M孤I_S忧-信号。 Then, two flip-flop circuit outputs (curve with two differential line drivers 4108 and 4110 (voltage mode) are split into a differential pair signal M lone I_DataO +, M and M lone LDataO-W isolated I_S worry +, M lone I_S worry - Great .H input exclusive NOR NOR) port, or logic element 4112 is connected to receive the dATA and outputs of both flip-flops, and generates a second flip-flop output to provide input data, sent and generating M solitary I_S worry +, M lone I_S worry - signal. 为了简便,XNOR口具有反相泡,用于指示它有效地使产生选通的触发器的Q输出反相。 For simplicity, the XNOR foam having an inverting port, for indicating that effective to produce gating Q output of flip-flop inverted.

[0266] 在图41的接收部分4120中,M孤LDataO+、M孤LDataO-和M孤I_S忧+、M孤1_ S忧-信号分别由两个差分线接收机4122和4124的每一个所接收,接收机从差分信号产生单个输出。 [0266] In the receiving portion 4120 of FIG. 41, M lone LDataO +, M and M lone lone LDataO- I_S worry +, M lone worry 1_ S - 4122 and 4124 each of the received signals from the two differential line receiver , receiver generates a single output signal from the differential. 然后,放大器的输出被输入两个输入异或狂〇时n、电路或逻辑元件的各输入端,后者产生时钟信号。 Then, the output of the amplifier is input to two-input exclusive OR when n mad square, each of the input circuits or logic element, which generates a clock signal. 时钟信号用于触发两个D型触发器电路4128和4130的每一个,后者通过延时元件4132接收DATA信号经延时的形式,其一(4128)产生数据"0"值而另一个(4130)产生数据"1"值。 Clock signal for triggering the two D flip flop circuits 4128 and 4130 each of which is received by the delay element 4132 delays the signal DATA form, one (4128) generates data '0' values ​​and the other ( 4130) generating a data value "1". 时钟也具有来自XOR逻辑的独立输出。 Clock is also an independent output from the XOR logic. 由于时钟信息分布在DATA 和STB线之间,因此状态间的信号变换都比时钟速率的一半慢。 Since the clock information is distributed between the DATA and STB lines, the signal conversion between states than half the slow clock rate. 由于用DATA和STB信号的异或处理再现了该时钟,因此系统有效地容许与时钟信号直接在单个专用数据线上被发送的情况相比输入数据和时钟间偏离的两倍。 Since the reproduction clock with the XOR DATA and STB signals, the system effectively double the permissible deviation between the input data and clock with a clock signal directly in case of a single dedicated data line to be transmitted compared.

[0267] 为了使对噪声负面影响的抵抗力最大而W差分模式操作M孤I_Data+、M孤1_ 化ta-、M孤I_S忧+和M孤I_S忧-信号。 [0267] In order to make the negative effects of noise on the maximum resistance to differential mode and W M lone I_Data +, M 1_ solitary of ta-, M + and M lone I_S fear worries isolated I_S - signal. 差分信号通道的各部分是用传送信号的电缆或导线的特征阻抗的一半来源端接的。 Portions of the differential signal path is characterized by a signal transmission cable or line source impedance termination half. M孤I_Data+和M孤I_Data-在主机和客户端都是源端接的。 Solitary I_Data + M and M I_Data- isolated host and client are source terminated. 由于在给定时间处送两个驱动器仅有一个是活动的,因此在传输链路的源处总是存在端接。 Since the two feed drives at a given time only one is active, there is always at the source end of the transmission link. M孤I_S忧+和M孤I_S忧-信号仅由主机驱动。 M + and M lone I_S fear worries isolated I_S - signal is only driven by the host.

[0296] 图45和46分别说明延时的存在,延时在主机禁用或启用主机驱动器时会发生。 [0296] Figures 45 and 46 illustrate the presence of delay, the delay will occur when the host disables or enables the host driver. 在主机传递某些分组的情况下,譬如反向链路封装分组或往返延时测量分组,主机在期望分组被传递之后禁用线路驱动器,期望分组有图45所述的已被传输的参数CRC、选通对齐W 及全零分组。 In the case of some host transfer packet, such as the Reverse Link Encapsulation Packet or the round trip delay measurement packet, the host disables the line driver after the desired packets are transmitted, a desired packet has been transmitted in FIG Parameter CRC of claim 45, W aligned gate and All zero packets. 然而,如图45所示,线状态不必要从"0"瞬时切换至期望的较高值,然而送潜在地可用现有的某种控制或电路元件来实现,但需要一段时间,称为主机驱动器禁用延时时间段,来响应。 However, as shown in FIG. 45, the unnecessary line status is switched from "0" to a desired higher value instantaneously, although potentially available to send certain existing control or circuit elements to implement, but requires a period of time, called a host driver disable time delay period to respond. 尽管它几乎立即发生W致该时间段长度为0纳砂(nsec),然而它可W容易地扩展到某些10纳砂的较长时间段,它是期望的最大时间段长度,发生在保护时间1或者转向1分组时间段期间。 Although it is almost the actuation period length W 0 sodium sand (nsec) immediately occur, but it can be easily extended to W long period of time some of the sand 10 is satisfied, it is a desired maximum period length, occur in the protection 1 or turn Around 1 period of time a packet period.

[0305] A.状态机分组处理器 [0305] A. State Machine Packet Processor

[0306] M孤I链路上传输的分组非常快地被调度,通常速率在300Mbps或更高数量级上, 然而当然也可W根据需要而使用较低的速率。 [0306] I on M lone link packet transmissions are scheduled very quickly, typically in a rate of 300Mbps or more orders of magnitude, but of course also be used if necessary W lower rate. 送种类型的总线或传输链路速度对于当前商业上可用的(经济的)通用微处理器或用于控制的其它类似物而言太大了。 Species send type of bus or transfer link speed is too great for the other analogs (economical) general-purpose microprocessor for controlling or currently available commercially in terms of the. 因此,实现送种信号传输的实际实现是用可编程状态机来分解输入分组流,从而产生被传输或被重新定向到它们期望的适当音频-可视子系统的分组。 Therefore, the actual transmission types Achieved signal transmission is programmable state machine to decompose the input packet stream to produce a transmitted or redirected to the appropriate audio their desired - visual subsystem packets.

[0307] 通用控制器、处理器、或处理元件可W适当用来作用于或操纵诸如控制或状态分组送样的信息,它们对速度的要求较低。 [0307] General purpose controllers, processors, or processing elements may be suitable for acting on W such as manipulation or control or status packet kind of information, their requirements for low speed. 当接收到郝些分组(控制、状态、或其它预定义的分组)时,状态机应将它们通过数据缓冲器或类似处理元件传递到通用处理器,使得能作用于分组而提供期望的结果(效应),而音频和可视分组为了该作被传输到它们适当的目的地而起作用。 When receiving Hao these packets (control, status, or other pre-defined packets), the state machine should pass them through a data buffer or similar processing element to the general-purpose processor, such action could result in the packet to provide the desired ( effect) while the audio and visual packets are to be transmitted to the appropriate destination functions thereof.

[030引通过利用计算机应用中的微处理器(CPU)、或处理器、数字信号处理器值SP)、或者无线装置中的ASIC可用的处理效力或过度周期,可W在某些实施例中实现通用处理器操作,此与某些调制解调器或图形处理器使用计算机中CPU的处理效力来执行某些操作并减少硬件复杂度和费用的方式极相同。 [030 computer applications cited by using a microprocessor (CPU), or processor, the SP value of a digital signal processor), an ASIC or wireless device or potency over the available processing cycles, in certain embodiments W a general purpose processor to realize the same operation electrode, this process used to perform certain operations in the CPU computer and efficacy as some modems or graphics processors and reduce hardware complexity and cost manner. 然而,送会消极地影响处理速度、时序或送种元件的总操作。 However, the sending may negatively affect the operation of the overall processing speed, timing, or send the element species. 因此在许多应用中,最好为该通用处理选择专用电路或元件。 Therefore, in many applications, dedicated circuits or elements are the best choice for this general processing.

[0309] 为了在显示器(微显示器)上观看图像数据,或者可靠地接收由主机发送的所有分组,显示器信号处理必须与前向链路信道定时同步。 [0309] In order to view the image data on a display (micro-display), or to reliably receive all packets sent by the host, the display signal processing must forward link channel timing synchronization front. 也就是说,到达显示器和显示器电路的信号必须在时间上同步,从而发生适当的信号处理。 That is, signals arriving at the display and the display circuits must be time synchronized to appropriate signal processing to occur. 图49的说明中给出可W实现送种同步的信号处理步骤或方法所实现的高电平状态图。 W may be given in the description of FIG. 49 to implement signal processing steps or a method of transmitting one of the sync achieved high state in FIG. 图49中,所示状态机4900的可能的前向链路同步"状态"被分类成一个异步顿(Async化ames)状态4904、两个捕获同步(AcquiringSync)状态4902 和4906、W及H个同步中(In-Sync)状态4908、4910 和4912。 In FIG 49, the state machine shown may forward link 4900 sync "state" is classified into an asynchronous Dayton (Ames of the Async) state 4904, two capture synchronization (AcquiringSync) state 4902 and 4906, W and H a synchronization (in-sync) state 4908,4910 and 4912.

[0310] 如开始步骤或状态4902所示,显示器W预先选定的"无同步"状态开始,并且在被检测的第一个子顿报头分组中搜索唯一字。 [0310] The starting step or state 4902, the display W pre-selected "no sync" state starts, and the search for the unique word in the first sub-header packet is detected Dayton's. 值得注意的是,该无同步状态表示其中选择类型I接口的最小通信设置或"后退"设置。 It is noted that this no sync state represents the minimum communication in which a Type I interface is provided to select or "reverse" setting. 当在搜索中找到唯一字时,显示器保留子顿长度字段。 When you find the only word in the search, display Dayton reserved sub-length field. 该第一个顿上不校验用于处理的CRC比特,或者直到获得同步为止。 For processing does not verify the CRC bits of a meal, or until synchronization is obtained. 如果该子顿长度为零,郝么同步状态处理按照该方法进行到送里标为"异步顿"状态的状态4904,表示尚未达到同步。 If the sub-zero length Dayton, Hao what the sync state processing proceeds to a state 4904 labeled sent in "Asynchronous Dayton" state according to this method, showing yet synchronized. 在图49中,处理中的该步骤被标为遇到cond3,即条件3。 In Figure 49, the processing in step is labeled Cond3 encountered, i.e. the condition 3. 否则,如果顿长度大于零,则同步状态处理进行到状态4906,接口状态在郝里被设为"已找到一个同步顿"。 Otherwise, if the Dayton length is greater than zero, then sync state processing proceeds to a state 4906, the state of the interface is set in the Hao "has found a synchronized Dayton." 在图49中,处理中的该步骤被标为遇到cond5,即条件5。 In Figure 49, the processing in step is labeled encountered cond5, i.e., conditions 5. 此外,如果对于大于0的顿长度状态机看到顿报头分组和良好的CRC确定,则处理进行到"已找到一个同步顿"状态。 In addition, if the state machine for a length greater than 0 Dayton see Dayton header packet and good CRC determination, the processing proceeds to the "found one sync Dayton" state. 在图49 中,处理中的该步骤被标为遇到cond6,即条件6。 In Figure 49, the processing in step is labeled COND6 encountered, i.e. the condition 6.

[0311] 在系统处在"无同步"状态之外的每种情况下,当检测到唯一字并且为子顿报头分组确定了良好CRC结果时,且子顿长度大于零,郝么接口状态变为"同步中"状态4908。 When [0311] In each case the system is in "no sync" state than when the unique word is detected and a good CRC result is determined for the sub-header packet Dayton, Dayton and the sub-length is greater than zero, the state of the interface becomes Hao "sync" state 4908. 在图49中,处理中的该步骤被标为遇到cond1,即条件1。 In Figure 49, the processing in step is labeled encountered COND1, i.e. a condition. 在另一方面,如果唯一字或子顿报头分组的CRC中的任何一个不正确,则同步状态处理去向或返回到"无同步顿"状态的接口状态4902。 In the interface state on the other hand, if the CRC unique word or sub-header of the packet in Dayton any incorrect, then the sync state processing destination or return to the 'no sync Dayton "state of 4902. 在图49的状态图中,该部分处理被标为遇到cond2,即条件2。 In the state diagram of Figure 49, the portion of the processing is labeled as COND2 encountered, i.e. the condition 2.

[0312] B.同步获得时间 [0312] B. Acquisition Time for Sync

[0313] 接口可被配置成在确定已失去同步并且返回到"无同步顿"状态之前容纳某一确定数量的"同步差错"。 [0313] interface may be configured to accommodate a certain number of "sync errors" prior to determining the synchronization has been lost and returns to the "no sync Dayton" state. 在图49中,一旦状态机已达到"同步中状态"并且未找到差错,贝U 它正连续地遇到条件1结果,并且保持"同步中"状态。 In Figure 49, once the state machine has reached the "IN-SYNC STATE" and no errors found, beta U it is continuously encountering a result of a condition, and remains "in sync" state. 然而,一旦检测到一个条件2结果, 处理使状态变为"一个同步差错"状态4910。 However, upon detecting a condition 2 result, the process becomes a state "one sync error" state 4910. 送样,如果处理导致检测到另一条件1结果, 则状态机返回"同步中"状态,否则它遇到另一条件2结果,并且移至"两个同步差错"状态4912。 Samples, if treatment results in a further condition is detected result, then the state machine returns to "sync" state, otherwise it encounters another condition 2 result, and moves "two synchronous error" state 4912. 同样,如果发生条件1,处理就使状态机返回"同步中"状态。 Similarly, if a condition occurs, processing returns the state machine causes the "IN-SYNC" state. 显而易见,遇见"链路关闭分组"会导致链路终止数据传输并返回"无同步顿"状态,送是因为没有可W与之同步的内容,送被称为遇见图49的状态图中的cond4,或条件4。 Obviously, meet "link shutdown packet" will cause the link to terminate data transfers and return to the "no sync Dayton" state, is sent to W because no synchronization with the content, referred to send cond4 met a state of FIG. 49 in FIG. , 4, or condition.

[0314] 可W理解,可能重复唯一字的"假拷贝",送出现在子顿内的某些固定位置处。 [0314] W can be appreciated, the unique word may be repeated "false copy", sent at some fixed location within the sub Dayton now. 在该情况下,状态机非常不可能与子顿同步,送是因为为了使M孤接口处理进行到"同步中"状态,子顿报头分组上的CRC必须有效。 In this case, the state machine is very unlikely to be synchronized with the sub-Dayton, is because in order to send a lone M interface processing proceeds to "sync" state, CRC on the sub-header packet Dayton must be valid.

[0315] 子顿报头分组中的子顿长度可能被设为零,W指示主机在链路被关闭前将只发送一个子顿,且M孤接口被置于或被配置成空闲休眠状态。 [0315] Sub Dayton Dayton length of the sub packet header may be set to zero, W indicates a sub-master only sends forward link Dayton is closed and the interface M solitary or configured to be placed in an idle hibernation state. 在该情况下,显示器必须在检测到子顿报头分组后立即接收前向链路上的分组,送是因为在链路转变为空闲状态之前仅有单个子顿被发出。 In this case, the display must be detected in the sub-header packet after the packet Dayton received immediately before the packet on the link, because only a single sub-transmission is sent before the link Dayton transition to the idle state. 在常规或典型操作中,子顿长度非零,当接口处在郝些被统称为图49中的"IN_SYNC"状态时仅处理前向链路分组。 In conventional or typical operations, the sub-zero length Dayton, when the interface is in those Hao is referred to as forward link packets only when the process in FIG. 49 "IN_SYNC" state.

[0316] 显示器与前向链路信号同步所需的时间是取决于子顿大小和前向链路数据速率的变量。 [0316] Time required to display the previous synchronization signal link depends on the size and sub Dayton forward link data rate is variable. 当子顿大小较大时,将唯一字的"假拷贝"检测为前向链路中部分随机或更随机数据的似然性也较大。 When the sub Dayton larger size, the unique word "false copy" is detected as the forward link data part of the random, or more random likelihood is larger. 与此同时,当前向链路数据速率较慢时,从假检测恢复的能力较低,完成它所需的时间较长。 At the same time, the current time to the link data rate is slower, less ability to recover from a false detection, it requires longer time to complete.

[0317] C.初始化 [0317] C. Initialization

[031引如前所述,在"启动"时,主机配置前向链路工作在IMbps的最小所需或所期望的数据速率之下,并且配置适用于给定应用的子顿长度和媒体顿速率。 [031 cited previously described, in the "start", before the Host Configuration link operating below the minimum required IMbps or desired data rate, and configuration applies to sub Dayton length and media given application Dayton rate. 也就是说,前向和反向链路都用类型I接口开始。 That is, both the forward and reverse links begin with type I interface. 当主机为客户机显示器(或其它装置)确定性能或期望配置时,送些参数一般仅临时使用。 When the host to the client display (or other device) to determine the performance or desired configuration, send some parameters are generally only temporary use. 为了请求显示器用显示性能分组应答,主机在前向链路上发送或传输子顿报头分组,其后跟着反向链路封装分组,该分组请求标志的位"0"被设为值一(1)。 In order to request that the display responds with packet display performance, the host sends a forward link or transmission sub-header packet Dayton, followed thereafter Reverse Link Encapsulation Packet, the grouping request flag bit "0" is set to a value of one (1 ). 一旦显示器在(用)前向链路上获得同步,它便在反向链路或信道上发出显示性能分组W及显示请求和状态分组。 Once synchronization is obtained on the forward link display (with) the front, which will be issued in the display performance of a reverse link packet or W and channel display Request and Status Packet.

[0319] 为了确定怎样重新配置最佳或期望性能级别的链路,主机检查显示性能分组的内容。 [0319] In order to best determine how to reconfigure the link or the desired performance level, the host checks the performance of the display content packet. 主机检查协议版本和最小协议版本字段来确认主机和显示器使用彼此兼容的协议版本。 The host examines the Protocol Version and Minimum Protocol Version fields to confirm that the host and display use versions of the protocol compatible with each other. 协议版本保持显示性能分组的前两个参数,因此,即使在协议的其它元件可能不兼容或者完全不能被认为兼容时,也能确定兼容性。 Protocol version two holding parameters before the display performance of the packet, even when other elements of the protocol might not be compatible or completely not be considered compatible and compatibility can be determined.

[0320] D.CRC处理 [0320] D.CRC Processing

[0321] 对于所有分组类型而言,分组处理器状态机确保CRC检验器被适当控制。 [0321] For all packet types, the packet processor state machine ensures that the CRC checker is controlled appropriately. 它也在CRC比较导致所检测到的一个或多个误差时使CRC误差计数器增加。 It is also that the CRC comparison results of the CRC error counter is incremented when a detected error or more. 而且它在每个被处理的子顿开始时重置CRC计数器。 And it resets the CRC counter at the beginning of each sub-Dayton process.

[0322] IX.分组处理 [0322] IX. Packet Processing

[0323] 对上述状态机接收到的每一类分组而言,它采取一个特定处理步骤或一系列步骤来实现接口的操作。 [0323] Each type of state machine described above in terms of the received packet, it takes a particular processing step or series of steps to implement operation of the interface. 前向链路分组一般按照下表XII所列的示例性处理而被处理。 Usually before being processed according to the following listed in Table XII to link packets exemplary process.

[032引X.降低反向链路数据速率 [032 primer X. Reducing the Reverse Link Data Rate

[0329] 发明人已观察到,为了实现非常期望的最大或更优化的(缩放)反向链路数据速率,可WW某种方式来调节或配置主机链路控制器所用的某些参数。 [0329] The inventors have observed that, in order to achieve highly desired maximum or more optimized (scale) reverse link data rate, can be adjusted in some way or WW certain parameters used for the host link controller. 例如,在用于传输反向链路封装分组的反向链路分组字段的时间内,M孤I_Stb信号对反复转换,W创建前向链路数据速率一半的周期性数据时钟。 For example, the reverse link packets in the time field for the transmission of the Reverse Link Encapsulation Packet, M lone I_Stb half of periodic data signal before the clock conversion repeated, W to create a link data rate. 送个的发生是由于主机链路控制器产生对应于MM)I_ DataO的M孤I_S忧信号,就好像它发出全零一样。 The generation occurs send a corresponding MM) I_ DataO signal of M lone I_S concern because the host link controller, if it sends all-zeroes. M孤I_S忧信号从主机被传送到显不器, 其中它用来产生用于从显示器传输反向链路数据的时钟信号,反向链路数据用它被发送回主机。 M lone I_S not worry signal is sent from the host significantly, where it is used to generate a clock signal for the reverse link transmission from the display data, reverse link data is sent back to it by the host. 图50中示出使用M孤I的系统中前向和反向通道上信号传输和处理所遇见的典型延时量。 FIG 50 shows a typical amount of delay and signal processing and transmission on a reverse channel and found the system using the M I is isolated in front. 在图50,所示一系列延时值1. 5纳砂、8. 0纳砂、2. 5纳砂、2. 0纳砂、1. 0纳砂、1. 5纳砂、8. 0纳砂和2. 5纳砂分别接近S忧+/-产生、电缆传输至显示器、显示器接收机、时钟产生、信号同步、DataO+/-产生、电缆传输至主机、W及主机接收机级的处理部分。 In FIG. 50, a series of delay values ​​shown satisfied sand 1.5, 8.0 sodium sand, 2.5 sodium sand, 2.0 sodium sand, 1.0 sodium sand, 1.5 sodium sand, 8.0 2.5 is satisfied sand and sand are satisfied generated close +/- S worry, cable transmission to the display, display receiver, clock generation, signal synchronization, DATAO +/- generation, cable transfer processing to the host, W, and host receiver stages section.

[0330] 根据所遇到的前向链路数据速率和信号处理延时,要完成该"往返"效应或一组事件可能比M孤I_S忧信号需要多于一个周期的时间,造成消耗不希望的时间或周期量。 [0330] The front face of the forward link data rate and signal processing delays, to complete the "round trip" effect or set of events may be more than one period of the signal M takes time to worry I_S isolated, resulting in undesirable consumption period of time or amount. 为了防止该问题,反向速率除数使反向链路上的一比特时间能跨越M孤I_S忧信号的多个周期。 To prevent this problem, the Reverse Rate Divisor makes a bit time on the reverse link can span multiple cycles of the signal M lone I_S worry. 送意味着反向链路数据速率低于前向链路速率。 It means to send reverse link rate less than the forward link data rate.

[0331] 应该注意,通过接口的实际信号延时长度可能根据所使用的各特定主机-客户机系统或硬件而改变。 [0331] It should be noted that, in accordance with each specific host may be used by the actual length of the delay signal interface - the client system or hardware changes. 各系统一般通过用往返延时测量分组来测量系统中的实际延时而表现得更加好,因此反向速率除数能被设为最佳值。 Each system is typically measured by the packet round-trip delay is measured by the actual delay in a system and performance was even better, so the Reverse Rate Divisor can be set to an optimum value.

[0332] 往返延时通过使主机将往返延时测量分组发送至显示器来测量。 [0332] round trip delay by the round trip delay measurement packet to the host sent to the display is measured. 显示器通过在该分组内预先选择的测量窗内或期间内将一个1序列发送回主机而对该分组应答,该测量窗称为测量时间段字段。 Through the display period packet in the pre-selected measurement window 1 or a sequence back to the host and the response packet, referred to as the measurement period measurement window field. 该测量的详细时序已在前说明。 The detailed timing of this measurement is first described. 往返延时用于确定能安全采样反向链路数据所处的速率。 Means for determining the round trip delay safe sampling rate at which the reverse link data.

[0333] 往返延时测量包括确定、检测、或计数前向链路数据时钟间隔的数目,所述时钟间隔发生在测量时间段字段的开始与在主机处从显示器接收到0xff、0xff、0x00应答序列的时间段开始之间。 [0333] round trip delay measurement consists of determining, detecting the number of front or forward link data clock count interval, the clock interval occurs at a measurement time period beginning with the field received from the display to 0xff, 0xff at the host, a response 0x00 between the sequence starting period. 注意到来自显示器的应答可能在测量计数将要增加之前的一小部分前向链路时钟周期之前而被接收。 Noting the response from the display could be received before the link clock period before the measurement of a small portion of the previous count to be increased. 如果该未经修改的值用于计算反向速率除数,则它会引起反向链路上由不可靠数据采样所引起的比特误差。 If this unmodified value is used to calculate the Reverse Rate Divisor, it will cause a bit error from the sampled data is not reliable due to the reverse link. 图51中说明了该情况的一个示例,其中W 图形形式说明了表示主机处的M孤LData、主机处的M孤I_S忧、主机内的前向链路数据时钟、W及延时计数等信号。 FIG. 51 illustrates an example of this case, wherein W represents a graphical form described solitary LDATA M at the host, the host at the M isolated I_S concerns, within the host before the link data clock, and delay counting signal W . 在图51中,应答序列在延时计数要从6增至7之前的一小部分前向链路时钟周期之前而被接收。 In Figure 51, the response sequence was received before the delay count and forward link clock period before a fraction from 6 to seven. 如果假定延时为6,则主机将总是在比特转变后或可能在比特转变中间对反向数据采样。 If the delay is assumed to 6, then the host will always be a bit transition or possibly after an intermediate bit transition sample the reverse data. 送会导致主机处的错误采样。 Delivery can lead to erroneous sampling at the host. 为此,经测量的延时应该在用它来计算反向速率除数前被增一。 For this reason, the measured delay should be calculated by using a reverse rate divisor before it.

[0334] 反向速率除数是主机在对反向链路数据采样前应该等待的M孤I_Stb周期数。 [0334] M Reverse Rate Divisor is the number of cycles before the host solitary I_Stb reverse link data sampling should wait. 由于M孤I_S忧W前向链路速率的一半的速率循环,因此经纠正的往返延时测量需要被除W2,然后向上取整至下一个整数。 Since the front half of the rate W M lone worry I_S link rate cycle, and therefore by the round trip delay measurement needs to be corrected W2 of addition, and then rounded up to the next integer. 该关系用公式表示如下: The relationship is represented by the following formula:

Figure CN101030952BD00421

[0336] 对于给定示例,送变成: [0336] For a given sample, send becomes:

Figure CN101030952BD00422

[033引如果该例中所用的往返延时测量与不是6而是7,则反向速率除数也会等于4。 [033 If the primer used in the examples and the round trip delay measurement, but not 7 6, then the Reverse Rate Divisor would equal 4. [0339] 反向链路数据由主机在反向链路时钟的上升沿采样。 [0339] The reverse link data is sampled by the host on the rising edge of the Reverse Link Clock. 送是主机和客户机(显示器)中用于产生反向链路时钟的计数器或者类似已知的电路或装置。 It is sent to the host and client (display) to generate the Reverse Link Clock counter or similar known circuit or device. 计数器被初始化,使得反向链路时钟的第一个上升沿发生在反向链路封装分组的反向链路分组字段内第一比特开始处。 The counters are initialized so that the Reverse Link Clock occurs at the beginning of the first rising edge of the first bit of the Reverse Link Packets field of the Reverse Link Encapsulation Packet. 送在图52中为了下面给出的示例而说明。 In order to send and the description below the example given in FIG. 52. M孤I_S忧信号的各上升沿处的计数器增量,W及它们绕回前发生的计数数量由反向链路封装分组内的反向速率除数参数设置。 Counter is incremented at each rising edge of the signal M lone I_S worry, W, and the count number thereof by wraparound occurred before in the reverse rate divisor parameters in the Reverse Link Encapsulation Packet is provided. 由于M孤I_S忧信号在前向链路速率的一半处转换,因此反向链路速率是由反向速率除数所除的前向链路速率的一半。 Since M lone I_S worry signal conversion at the front half of the forward link rate, and therefore the reverse link rate is one half of the former divided by the Reverse Rate Divisor is the link rate. 例如,如果前向链路速率为200Mbps且反向速率除数为4, 则反向链路数据速率表示为: For example, if the forward link rate of 200Mbps and Reverse Rate Divisor is 4 then the reverse link data rate is expressed as:

Figure CN101030952BD00423

[034。 [034. 图52中示出反向链路封装分组中M孤LDataO和M孤I_S忧信号线的定时示例,其中说明所用的分组参数具有下列值: FIG 52 shows a timing example in a Reverse Link Encapsulation isolated LDataO M and M signal lines isolated I_S worry packets, where the packet parameters used for the description have the following values:

[0342] 分组长度=1024(0x0400) 转向1长度=1 [0342] Packet Length = 1024 (0x0400) Turn Around 1 Length = 1

[0343] 分组类型=65(0x41) 转向2长度=1 [0343] Packet Type = 65 (0x41) Turn Around 2 Length = 1

[0344] 反向链路标志=0 反向速率除数=2 [0344] Reverse Link Flags = 0 Reverse Rate Divisor = 2

[0345]参数CRC= 0xdb43 全零为OxOO [0345] Parameter CRC = 0xdb43 all-zero OxOO

[0346]选通对齐为OxOO,OxOO,0x60 [0346] aligned gate OxOO, OxOO, 0x60

[0347] 分组长度和参数CRC字段间的分组数据为: [0347] Packet data between the Packet Length and Parameter CRC fields is:

[034引0x00,0x04,0x41,0x00,0x02,0x01,0x01,0x43,Oxdb,0x00,0x00,0x60,0x00... [034 cited 0x00,0x04,0x41,0x00,0x02,0x01,0x01,0x43, Oxdb, 0x00,0x00,0x60,0x00 ...

[0349] 从显示器返回的第一反向链路分组为显示器请求和状态分组,其分组长度为7,分组类型为70。 [0349] The first reverse link packet returned from the display is the Display Request and Status Packet which the packet length is 7, 70 for the packet type. 该分组W字节值0x07,0x00,0x46...开始,依此类推。 The packet byte value 0x07,0x00,0x46 ... W start, and so on. 然而,图52中仅可看见第一个字节(0x07)。 However, Figure 52 only see the first byte (0x07). 为了说明实际反向链路延时,该第一反向链路分组在图中时间上被移位将近一个反向链路时钟周期。 In order to explain the actual reverse link delay, the first reverse link packets in the figure is shifted nearly one reverse link clock cycle time. 虚线迹线示出具有零主机到显示器往返延时的理想波形。 The broken line trace shown over the waveform with zero host to display round-trip delay.

[0350] 选通对齐字节在参数CRC字段的MS字节后被传送,然后是全零字段。 [0350] In the transfer gate alignment byte after byte Parameter CRC field of the MS, then the all zero field. 来自主机的选通从1切换为零,然后当来自主机的数据改变形成较宽脉冲的电平时返回至1。 Strobe from the host is switching from one to zero, and then returns to normal when the data from the host 1 changes the electric forming wider pulses. 当数据变为零时,选通W较高速率切换,仅有数据线上数据内的变化会引起对齐字段末尾处的变化。 As the data goes to zero, the strobe switches at a higher rate W, only changes in data on the data line causes a change at the end of the alignment field. 选通为了由扩展时间段的数据信号的固定0或1电平引起的图中剩余部分W较高速率切换,转变落在脉冲图案(边沿)上。 FIG gated by the extension to the data signal of a fixed period of time the level 0 or 1 of the remaining portion due to the higher rate switching W, transition falling on the pulse pattern (edge).

[0351] 当时钟启动来容纳反向链路分组时,主机的反向链路时钟在转向I时间段之前为零。 [0351] When the clock to start receiving a reverse link packet, the host is zero reverse link clock period before the steering I. 图下部的箭头表示何时采样数据,送将从W下掲示中变得显而易见。 FIG arrow indicates when the lower portion of the sample data shown in the feed will become apparent kei W. 所示正被传输的分组字段的第一个字节(送里是11000000)在转向1之后开始,线电平自主机驱动器被禁用后稳定。 The first byte of the packet field being transferred as shown (11000000 in feed) after 1 starts turning, the line level stability from the host driver being disabled. 第一比特通路中的延时,W及位3中的延时,可W在数据值ata)信号的虚线中所见。 A first delay path bit, 3-bit and W delay, may be seen in broken lines W data values ​​ATA) signal.

[0352] 在图53中,可W观察到基于前向链路数据速率的反向速率除数的典型值。 [0352] In FIG. 53, W can be observed on the front link data rate to reverse rate divisor typical values. 实际反向速率除数作为往返链路测量的结果而被确定,W保证适当的反向链路操作。 The actual Reverse Rate Divisor is determined as a result of round-trip link measurement, W ensure proper reverse link operation. 第一区域5302对应于安全操作区域,第二区域5304对应于边缘特性的区域,而第H区域5306表示不能适当操作的设置。 A first region 5302 corresponds to an area of ​​safe operation, a second region 5304 corresponds to a region of the edge characteristics of the H region 5306 indicates settings are not operating properly.

[0353] 当或在前向或在反向链路上用任一接口类型设置操作时,往返延时测量和反向速率除数设置相同,送是由于它们用实际时钟周期的单位来表示并操作,而非用被发射或被接收到达比特数。 [0353] When the forward or reverse link or when using any type of interface to a set operation, round-trip delay measurement and Reverse Rate Divisor can be set the same, because they send units to represent actual clock period and operate , not achievable bit number received by or transmitted.

[0354] XI.转向和保护时间 [0354] XI. Steering and protection time

[0355] 如前所述,反向链路封装分组内的转向1字段W及往返延时测量分组内的保护时间1指定了允许主机接口驱动器在启用显示器接口驱动器之前被禁用的长度值。 [0355] As described above, the steering field W 1 and allows the host interface drivers length measuring round-trip delay value guard time is specified within the packet 1 to be disabled before the display interface drivers is enabled in the Reverse Link Encapsulation Packet. 转向2和保护时间2字段提供了允许显示器驱动器在启用主机驱动器前被禁用的时间值。 Turn Around 2 and Guard Time 2 fields provide time values ​​allow the display drivers to be disabled before the host drivers are enabled. 保护时间1和保护时间2字段一般用长度的预设或预先选择的值来填充,它不会被调节。 Guard Time 1 and Guard Time 2 fields are generally used preset or pre-selected values ​​of the length of the filling, it will not be adjusted. 根据所使用的接口硬件,送些值可W用经验数据研究得出并且为了改进操作而在某些情况下被调节。 The interface hardware being used, these values ​​sent W with empirical data can be obtained and studies for improving the operation to be adjusted in some cases.

[0356] 若干因素对转向1的长度确定起作用,并且送些是前向链路数据速率W及主机内MDDLData驱动器的最大禁用时间。 [0356] Several factors determine the length of a steering function, and is sent to some maximum disable time of the forward link data rate and W within the host MDDLData drive. 最大主机驱动器禁用时间在表XI中规定,它示出驱动器需要约10纳砂最大时间来禁用W及约2纳砂来启用。 The maximum host driver disable time is specified in Table XI, which shows the drive needs satisfied sand about 10 W, and the maximum disable time of about 2 to enable sand satisfied. 主机驱动器要被禁用的前向链路时钟的最小数量按照下列关系来表示: Before the host driver to be disabled is expressed according to the following relationship between the minimum number of link clock:

[0361] 联合上面两个公式,可W看见,接口类型因子项被消去,转向1被定义为: [0361] Combined the above two formulas, W can be seen, interface type factor item is erased, the steering is defined as 1:

Figure CN101030952BD00433

[0363] 例如,1500Mbps的类型III前向链路会使用下面的转向1延时: [0363] For example, before 1500Mbps Type III forward link would use a Turn Around 1 delay of the following:

Figure CN101030952BD00434

[0365] 随着往返延时的增加,从主机被禁用点到显示器被启用时的时序边缘得到改进。 [0365] As the round trip delay increases, the host is disabled to the timing point of the display is enabled when the edge is improved.

[0366] 转向2 -般用来确定时间长度的因子为前向链路数据速率、显示器内MDDLData 驱动器的最大禁用时间、W及通信链路的往返延时。 [0366] Turn-Around 2 - as for the length of the forward link data rate determination time factor, the maximum disable time within the display MDDLData drive, W, and round trip delay of the communication link. 禁用显示器驱动器所需时间的计算一般与上面为主机驱动器所讨论的时间相同,并且按照下列关系定义: Display driver disable time required for the calculation time is the same as above the general host driver discussed above, and is defined according to the following relationship:

[037引XIII.操作 [037 cited XIII. Operation

[0379] 图54a和54b中示出使用本发明实施例的接口操作期间处理数据和分组所采用的一般步骤概述,W及处理图55中分组的接口装置的综述。 Summary [0379] FIGS. 54a and 54b shows the general steps of the present invention using the embodiment of the interface during the operation of processing data and packets used outlined W and interface apparatus processing the packets in FIG. 55. 在送些图中,处理在步骤5402处开始,确定客户机和主机是否用通信通道所连接,送里通信通道是电缆。 In these figures feed, the process begins at step 5402, it is determined whether or not the client and host are connected using a communication channel, the communication channel is sent in the cable. 送会通过由主机使用周期性轮询、在主机输入端(譬如在USB接口处所见)检测连接器或电缆或信号的存在的软件或硬件、及其它已知技术而发生。 Will send, occurs (for example, as seen in the USB interface) detecting the presence of connectors or cables or hardware or software signals, and other known techniques by using periodic polling by the host at the host input. 如果没有客户机与主机相连,则它会根据应用而简单地进入某预定长度的等待状态、进入休眠模式、或者被阻止而等待将来使用,后者要求用户采取行动来重新激活主机。 If there is no client connected to the host, it applies simply enter a wait state of some predetermined length, enter sleep mode, or are blocked waiting for future use according to, which requires a user to take action to reactivate the host. 例如,当主机驻留在计算机型装置上时,用户可能必须点击屏幕图标或请求激活主机处理去寻找客户机的程序。 For example, when a host resides on a computer type device, the user may have to tap the screen icon or request activation of host processing program to find clients. 同样,USB型连接的简单插入,譬如类型U接口所用,会激活主机处理。 Similarly, USB-connected simply inserted, for example, the type used in the U-interface will activate host processing.

[0380] 一旦客户机与主机相连,反之亦然,或被检测为存在,则或主机或客户机在步骤5404和5406中发出适当的分组请求服务。 [0380] Once a client connected to the host, or vice versa, or detected as being present, or the host or client sends appropriate packets requesting service in steps 5404 and 5406. 客户机在步骤5404中会或发出显示服务请求或发出状态分组。 The client in step 5404 or may issue a service request or issue display Status Packet. 注意到,如上所述,链路可能先前已关闭或者处在休眠模式,因此送可能不是允许的通信链路的完全初始化。 It noted that, as described above, the link may have been previously shut down or in a sleep mode, and therefore may not be allowed to send a full initialization of the communication link. 一旦通信链路得到同步且主机试图与客户机通信,则客户机还需要将显示性能分组提供给主机,如步骤5408中所示。 Once the communication link is synchronized and the host is trying to get in communication with a client, the client also needs to display performance packet to the host, as shown in step 5408. 主机现在可W开始确定客户机能提供的支持类型,包括传输速率。 W hosts can now begin to determine the type of client can provide support, including transfer rates.

[0381] 一般而言,主机和客户机还在步骤5410中协商要被使用的服务模式类型(速率/ 速度),例如类型I、类型U、类型II等等。 [0381] Generally, the host and client also negotiate the service mode in step 5410 to be used in the type (rate / speed), such as type I, Type U, Type II and the like. 一旦建立了服务类型,主机就开始传输信息。 Once a service type, the host begins to transmit information. 此夕F,主机可W用往返延时测量分组来与其它信号处理平行地优化通信链路的定时,如步骤5411中所示。 This evening F., The host may use the round trip delay measurement packet W to optimize the timing of the communication links in parallel with other signal processing, as shown in step 5411.

[0382] 如前所述,所有传输都W子顿报头分组开始,在步骤5412中被传输,其后是数据类型,送里是视频和音频流分组、W及填充符分组,在步骤5414中所示被传输。 [0382] As described above, all transmissions Dayton W sub-header packet is transmitted in step 5412, followed by the type of data, video and audio transmission in a packet stream, W, and filler packets, in step 5414 FIG transmitted. 音频和视频流数据将预先已被准备好并被映射入分组,而填充符分组根据需要被插入来填满媒体顿所需的比特数。 Audio and video stream data has been ready in advance and mapped into packets, and filler packets to fill the required number of bits needed to be inserted Dayton media. 主机可W将诸如前向音频信道使能分组送样的分组发送至活动声音装置,或另外,主机可W用上述其它分组类型传输指令或信息,送里示出传输色图、比特块传输或步骤5416中的其它分组。 Host may be W, such as the front so that the audio channels can be grouped to send samples of a packet transmitted to the active acoustic device, or in addition, the host may be W with the above-described other packet type transmission instruction or the information sent in the illustrated transmission color chart, a bit block transfer or other packet in step 5416. 此外,主机和客户机可W使用适当分组交换与键盘或指示装置有关的数据。 In addition, the host and client can exchange packet W using the appropriate data relating to a keyboard or pointing device.

[0383] 在操作期间,若干不同事件之一会发生,送会导致主机或客户机期望不同的数据速率或接口模式类型。 [0383] During operation, one of several different events can occur, or cause the host to send the client a different data rate or a desired type of interface mode. 例如,计算机或其它传送数据的装置会遇到处理数据中的下载条件, 它造成分组的准备或表示变慢。 For example, a computer or other device may encounter data transfer processing of the data is downloaded, it causes a packet to prepare slow or expressed. 接收数据的显示器会从专用AC电源变为更有限的电池电源,并且或者不能同样快地传输数据、容易地处理指令,或者不能在更有限的电源设置下试用同等程度的分辨率或色深。 Receiving display data from a dedicated AC power source will become more limited battery power source, and either not transmit data as quickly, easily processing instructions, or trial use the same degree of resolution or color depth under the more limited power settings. 或者,限制条件可W被消除或者消失,允许任一装置W高速率传输数据。 Alternatively, the restrictions may be eliminated or disappears W, W apparatus allows any high-speed transmission data. 由于送是越来越期望的,因此可W作出请求W改变到较高的传输速率模式。 Since feeding is increasingly desirable, therefore W W makes a request to change to a higher transfer rate mode.

[0384] 如果送些或其它类型的已知条件发生或改变,则或主机或客户机会检测到它们并且试图重新协商接口模式。 [0384] If the condition is known or to take some other type of occurrence or changed, or the host or client may detect them and try to renegotiate the interface mode. 送在步骤5420中示出,其中主机将接口类型切换请求分组(InterfaceTypeHandoffRequest化ckets)发送至客户机,请求向另一模式的切换,客户机发出接口类型确认分组(InterfaceTypeAcknowledgePackets),确认被探寻的变化, 然后主机发出执行类型切换分组(PerformType化ndoff化ckets)来作出向指定模式的变化。 Sent in step 5420 is shown, wherein the host interface Type Handoff Request Packet (InterfaceTypeHandoffRequest of ckets) to the client, a request to switch to another mode, the client sends Interface Type Acknowledge Packets (InterfaceTypeAcknowledgePackets), confirmation is sought change and the host sends perform type Handoff packet (PerformType of ndoff of ckets) to make the change to the specified mode.

[0385] 虽然不需要特定的处理次序,客户机和主机也能交换与指向或从指示装置、键盘或主要与客户机相关的其它用户类型的输入装置接收到的数据有关的分组,然而送些元件也可W存在于主机端。 [0385] Although no specific order of processing, the client and host can also exchange point or received from a pointing device, a keyboard or other user major types of input devices associated with the client data packets related to, but send some W elements may also be present in the host. 送些分组一般用通用过程或类型元件且非状态机来处理巧502)。 Usually send some packets with the general process or type element and not the state machine 502 to process coincidence). 此夕F,上面讨论的某些指令也可由通用处理器来处理巧504, 5508)。 This evening F., Discussed above, some instructions can be processed by a general purpose processor 504 Qiao, 5508).

[0386] 在主机和客户机之间交换了数据和指令之后,在某些点上作出决定是否要传输附加数据,或者主机或客户机是否要停止对传输服务。 After the [0386] exchange of data and instructions between the host and client, at some point a decision whether or not to transmit additional data, or the host or client is going to cease transmission service. 送在步骤5422中示出。 Sent in step 5422.. 如果链路要进入或休眠状态或完全被关闭,则主机将链路关闭化ink化Utdown)分组发送至客户机,并且两端都终止数据传输。 If the link is to enter a sleep state or is closed or completely, the host sends a Link Shutdown of the ink of Utdown) packet to the client, and terminates the data transmission ends.

[0387] 在上述操作处理中被传输的分组将用上面关于主机和客户机控制器讨论的驱动器和接收机来传输。 [0387] In the above operations processing will be transferred to the packet transmission driver and receiver above with respect to the host and client controllers discussed. 送些线路驱动器和其它逻辑元件与上述状态机和通用处理器相连,女口图55的综述所述。 These transmission line drivers and other logic element and the state machine and general processors, Summary of the female opening 55 of FIG. 在图55中,状态机5502和通用处理器5504还与其它未示出的元件相连, 譬如专用USB接口、存储器元件、或驻留在它们所交互动力的链路控制器外的其它组件,包括、但不限于;数据源、W及可视显示器装置的视频控制芯片。 In FIG 55, a state machine 5502 and general processors 5504 is also connected to other elements not shown, such as a dedicated USB interface, memory elements, or other components residing outside of the link they interacted power controller comprising , but not limited to; the video data source control chip, W, and a visual display device.
