Abstract
An apparatus for a service node used in a multimedia network. The apparatus has a data distributor circuit, and a decoder. The data distributor card has a data port for coupling with a data stream. The data distributor circuit has a relational code for determining whether an address field of a data packet of the data stream is intended for local distribution to peripheral devices by the distribution circuit. The decoder, in communication with the distribution circuit, has a virtual channel filter for filtering the address field to route the data packet to at least one data port, such as that associated with a peripheral device. An incorporator circuit is provided that is electrically-coupled to the data port to insert an address value having a relational code and a virtual channel code in a data input from the at least one data port. The incorporator then inserts the data input from the at leas tone data port into the data stream. In a method of the invention, interfacing a multimedia communications data stream having a plurality of data packets is provided. Inputing a data packet of the data stream, determining whether an address field of the data packet is intended for local dist…
