1. A system for processing data, said system comprising: a first circuit for receiving transport packets carrying the data; and memory comprising a plurality of contexts, each of the plurality of contexts comprising a context data buffer for storing portions of the data received by the first circuit and an incoming transport buffer for storing control data associated with the portions of the data stored in the context data buffer; wherein the data comprises data associated with a plurality of channels within a band, and wherein the first circuit maps the data associated with the plurality of channels within the 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.
