Abstract: Techniques for video encoding and decoding channel switch frames (CSF) to enable acquisition and re/synchronization of the video stream while preserv ing compression efficiency is provided. Systems and methods to process multi media data enabling channel switching are presented. The systems generate a CSF with one or more network adaptation layer (NAL) units as a random access point (RAP) frame. Back-to-back frames are transmitted which include the CS F and a non-RAP frame, each having the same frame ID number.

Abstract translation: 提供了视频编码和解码通道切换帧（CSF）的技术，以实现视频流的获取和再同步，同时保持压缩效率。 提出了处理能够进行通道切换的多媒体数据的系统和方法。 系统产生具有一个或多个网络适配层（NAL）单元的CSF作为随机接入点（RAP）帧。 发送背靠背帧，其包括CSF和非RAP帧，每个帧具有相同的帧ID号。
