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:
A method and apparatus for decoding multimedia data are described (Fig.5). One method includes receiving an encoded bitstream (605), identifying the location of one or more erroneous bits in the bitstream (610), generating a marker indicating the one or more erroneous bits (615), and inserting the marker in the bitstream to create a modified bitstream (620). The method can further comprise decoding the modified bitstream (625) using the marker to indicate the one or more erroneous bits (630). The method can further comprise initiating an error handling process when encountering the marker (635).
Abstract:
A method and apparatus (600) of processing multimedia data comprising a first section received in error are disclosed. The method comprises obtaining error distribution information corresponding to the first section. The method further comprises applying one of a plurality of error recovery schemes to the first section of the multimedia data based on the error distribution information.
