摘要： A system synchronizes one or more media streams, such as video stream or audio streams, by embedding frame identifiers in each compressed media stream, and then by using synchronizing signals to render each frame simultaneously by referencing the embedded frame identifier. Since the frame identifier is embedded in between encoded frames of the compressed media stream without altering any of the compressed, encoded data, the frame identifier information could be rapidly embedded without creating lag associated with manipulating existing data. This technique could be used, for example, to synchronize a single HD video on a plurality of display devices (e.g. a football game on a wall of video monitors), or to synchronize a plurality of HD video streams on a single display device (e.g. a plurality of live video feeds on a single computer monitor).
摘要翻译：系统通过在每个压缩媒体流中嵌入帧标识符，然后通过参考嵌入的帧标识符同时使用同步信号来呈现每个帧来同步一个或多个媒体流，例如视频流或音频流。由于帧标识符被嵌入在压缩媒体流的编码帧之间，而不改变任何压缩的编码数据，所以可以快速嵌入帧标识符信息，而不会产生与操纵现有数据相关的滞后。例如，该技术可以用于在多个显示设备（例如，视频监视器的墙壁上的足球游戏）上同步单个高清视频，或者在单个显示设备上同步多个HD视频流（例如，在单个计算机监视器上的多个实况视频馈送）。
