Abstract
A device receives packets associated with a program stream at an addressable communications port, and assigns them to one of a plurality of QAM channels. Multiplexed program packets, DOCSIS data or multimedia packets or a combination of both, are transmitted over the QAM channel. DSG messaging transports requests for content to a server, transports queries to mapping tables and returns information from the tables to a manager that, along with processors, determine which channel to use for downstream transport of the multiplexed streams. The manager assigns a connection identifier corresponding to a channel and program number combination to the packets, and sends the identifier, via DSG, to the requesting/receiving user device; the identifier instructs the user device how to tune and receive the requested packets. The identifier may use seven bits for program numbers, two for output port number and two for channel frequency.
