Abstract: In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

Abstract: Techniques for video encoding and decoding channel switch frames (CSF) to enable acquisition and re/synchronization of the video stream while preserving compression efficiency is provided. Systems and methods to process multimedia 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 CSF and a non-RAP frame, each having the same frame ID number.

Abstract: Techniques for video encoding and decoding a common guide media logic cha nnel (MLC) to enable fast acquisition and re/synchronization of the video st ream while preserving compression efficiency are provided. Systems and metho ds to process multimedia data using channel switch frames are presented. The system comprises an encoder operative to generate a common guide media logi cal channel (MLC) of a plurality of channel switch frames (CSFs), each respe ctive active channel having one or more CSFs in the guide MLC. The decoder i n 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 de coded set of the plurality of CSFs on a display and automatically switches t o a primary bitstream of an active channel associated with a selected one di splayed CSF.
