摘要： A communication system including a transmitter, a receiver, and a TMDS-like link, in which video data and auxiliary data (typically including timing data associated with other auxiliary data) are transmitted from the transmitter to the receiver, or in which video data are transmitted over the link from the transmitter to the receiver, and auxiliary data (typically including timing data associated with other auxiliary data) are transmitted from the receiver to the transmitter. In typical embodiments the auxiliary data include one or more streams of audio data. Other aspects are transmitters and receivers for use in such a system, methods for sending auxiliary data and video data over a TMDS-like link, methods for transmitting and recovering clocks for auxiliary data transmitted over such a link, methods for synchronizing auxiliary data transmitted over such a link with video data transmitted over such a link, and methods for generating clocks having frequency closely matching the rate at which the auxiliary data are transmitted over such a link.

摘要： A scheme to reduce clock jitter is disclosed in applications where video content is transmitted through multiple stages, each having a switch allowing that stage's video stream to be selected. The video data is re-clocked using a new clock at each stage. Before re-clocked, the video data from the preceding stage is scaled into a constant resolution using a digital scaler. Since the downstream stages could re-clock the video as if it were sent at the same frequency, there is no need to anticipate the changeable video frequency and to create the necessary low-jitter clock in programmable logic.
摘要翻译：在通过多个级传送视频内容的应用中公开了一种减少时钟抖动的方案，每个阶段都具有允许选择该级的视频流的开关。视频数据在每个阶段使用新的时钟重新计时。在重新计时之前，使用数字定标器将前一级的视频数据缩放为一个恒定的分辨率。由于下游阶段可以将视频重新录像，就像以相同的频率发送，所以不需要预测可变视频，并在可编程逻辑中创建必要的低抖动时钟。
