摘要： Techniques for video encoding and decoding a common guide media logic channel (MLC) to enable fast acquisition and re/synchronization of the video stream while preserving compression efficiency are provided. Systems and methods to process multimedia data using channel switch frames are presented. The system comprises an encoder operative to generate a common guide media logical channel (MLC) of a plurality of channel switch frames (CSFs), each respective active channel having one or more CSFs in the guide MLC. The decoder in the system is operative to decode a set of the plurality of CSFs from the guide MLC. The decoder simultaneously displays programming content of the decoded set of the plurality of CSFs on a display and automatically switches to a primary bitstream of an active channel associated with a selected one displayed CSF.

摘要： In general, this disclosure describes techniques of compensating for differences between a clock associated with an input stream of media data and a clock associated with an output stream of media data. Due to drift between a clock that governs the rate at which a transcoder receives media data units ( MDUs ) and a clock that governs the rate at which the transcoder outputs MDUs, the transcoder may receive MDUs at a rate that is faster or slower than a rate at which the transcoder outputs the MDUs. The transcoder compensates for such differences by identifying sets of received MDUs that account for a time equal to an output period minus a correction magnitude, modifying the identified sets of MDUs such that the sets of MDUs account for a time equal to the output period, and outputting the modified sets of MDUs as part of the output stream.
摘要翻译：通常，本公开描述了补偿与媒体数据的输入流相关联的时钟与与媒体数据的输出流相关联的时钟之间的差异的技术。由于控制代码转换器接收媒体数据单元（MDU）的速率的时钟和管理代码转换器输出MDU的速率的时钟之间的漂移，代码转换器可以以比速度更快或更慢的速率接收MDU 代码转换器输出MDU的速率。代码转换器通过识别占用等于输出周期的时间减去校正幅度的接收MDU的集合来补偿这样的差异，修改所识别的MDU组，使得MDU组占用等于输出周期的时间，以及输出修改后的MDU组作为输出流的一部分。
