Apparatus and method for data caching to reduce channel change delay

摘要

An apparatus performs a data caching operation responsive to a channel change event which reduces channel change times. According to an exemplary embodiment, the apparatus includes a cache memory operative to cache an incoming data stream responsive to a channel change command. A processor is operative to find program specific information included within the incoming data stream. A decoder is operative to decode the cached data stream responsive to the processor finding the program specific information.
