1. A system for processing data, said system comprising: a first circuit for receiving transport packets carrying multiplexed data associated with a plurality of channels; memory for storing a plurality of contexts, each of said plurality of contexts associated with a corresponding one of a plurality of video decoders; and wherein the first circuit demultiplexes and maps data associated with at least one channel of the plurality of channels to at least one of the plurality of contexts associated with at least one of the plurality of video decoders and maps data associated with at least another channel of the plurality of channels to at least another one of the plurality of contexts associated with at least another one of the video decoders; and wherein the plurality of channels carry a corresponding plurality of different content wherein the first circuit maps the data associated with the plurality of channels within a band to a particular one of the plurality of contexts, and maps the data associated with a portion of the plurality of channels within the band to another one of the plurality of contexts.
