Abstract:
A method of reducing the channel selection transition delay from a first media data channel to a second media data channel includes the operations of accumulating an independent media data frame and any related dependent media data frames based on a first decoder decoding at least a first portion of a second channel to form a second channel current media state, receiving a channel change request from a second decoder to change decoding to the second media channel, identifying an insertion position for a current independent frame relative to a current second channel frame set, and generating the current independent frame based on the second channel current media state corresponding to the insertion position. The dependent media data frames are used to modify the second channel current media state based on the independent media data frame.
