摘要： A compressively-encoding-resultant video signal resulting from compressively encoding a video signal, a first compressively-encoding-resultant audio signal resulting from compressively encoding a first audio signal having a synchronized relation with the video signal, a reference clock information signal relating to synchronization between the compressively-encoding-resultant video signal and the first compressively-encoding-resultant audio signal, and an indication timing information signal designating an indication timing of the video signal are multiplexed to get an AV multiplexing-resultant signal. A second audio signal is compressively encoded to get a second compressively-encoding-resultant audio signal. A sound-production-timing information signal is added to the second compressively-encoding-resultant audio signal to get a substitution playback audio signal. During playback, the substitution playback audio signal can be reproduced instead of the first audio signal while being synchronous with the video signal. The sound-production-timing information signal responds to the reference clock information signal, and relates to synchronization with the video signal.

摘要： Normally ordered robust VSB data are reordered in accordance with a first interleave to produce reordered robust VSB data. The reordered robust VSB data and ATSC data are reordered in accordance with a second interleave to produce normally ordered robust VSB data and reordered ATSC data. The normally ordered robust VSB data and reordered ATSC data are time multiplexed for transmission to a receiver. The receiver discards the reordered ATSC data or the normally ordered robust VSB data depending upon receiver type or user selection. A robust VSB receiver is able to process the normally ordered robust VSB data upstream of an outer decoder without an interleave thereby avoiding the delay associated with an interleave.

摘要： A system and method for voice transmission over high level network protocols. On the Internet and the World Wide Web, such high level protocols are HTTP/TCP. The restrictions imposed by firewalls and proxy servers are avoided by using HTTP level connections to transmit voice data. In addition, packet delivery guarantees are obtained by using TCP instead of UDP. Variable compression based on silence detection takes advantage of the natural silences and pauses in human speech, thus reducing the delays in transmission caused by using HTTP/TCP. The silence detection includes the ability to bookend the voice data sent with small portions of silence to insure that the voice sounds natural. Finally, the voice data is transmitted to each client computer independently from a common circular list of voice data, thus insuring that all clients will stay current with the most recent voice data. The combination of these features enables simple, seamless, and interactive Internet conferencing.
摘要翻译：一种用于通过高级网络协议进行语音传输的系统和方法。在互联网和万维网上，这样的高级协议是HTTP / TCP。通过使用HTTP级别的连接传输语音数据，可以避免防火墙和代理服务器的限制。此外，通过使用TCP而不是UDP获得分组传递保证。基于静音检测的可变压缩利用了人类语音中的自然沉默和停顿，从而减少了使用HTTP / TCP引起的传输延迟。沉默检测包括以小沉默的方式预订发送的语音数据的能力，以确保声音听起来很自然。最后，语音数据被独立于语音数据的通用循环列表发送到每个客户计算机，从而确保所有客户端将保持最新的语音数据。这些功能的组合可实现简单，无缝和互动的互联网会议。

摘要： This disclosure describes systems and methods for determining a voltage margin (or margin) of a serializer/deserializer (SerDes) receiver in mission mode using a SerDes receiver. This is done by time-division multiplexing a margin determination and a tap weight adaptation onto the same hardware (or software, or combination of hardware and software). In other words, some parts of a SerDes receiver (e.g., an error slicer and an adaptation module) can be used for two different tasks at different times without degrading the effectiveness or bandwidth of the receiver. Hence, the disclosed systems and methods allow a SerDes receiver to determine the SerDes margin in mission mode and without any additional hardware or circuitry on the receiver chip.
摘要翻译：本公开描述了使用SerDes接收机在任务模式下确定串行器/解串器（SerDes）接收器的电压余量（或余量）的系统和方法。这通过在相同的硬件（或软件或硬件和软件的组合）上进行裕度确定和抽头权重适配的时分复用来完成。换句话说，SerDes接收机的一些部分（例如，错误限制器和适配模块）可以在不同的时间用于两个不同的任务，而不降低接收机的有效性或带宽。因此，所公开的系统和方法允许SerDes接收机在任务模式下确定SerDes余量，并且在接收器芯片上没有任何额外的硬件或电路。
