Methods and apparatuses for use in switching between streaming video bitstreams

摘要

Improved methods and apparatuses are provided for switching of streaming data bitstreams, such as streaming data bitstreams typically used in video streaming and other related applications. Some desired functionalities provided herein include random access, fast forward and fast backward, error-resilience and bandwidth adaptation. The improved methods and apparatuses can be configured to increase coding efficiency of and/or reduce the amount of data needed to encode a switching bitstream.
