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
distribution, and routing the data packet to a data port if the data
packet is intended for local distribution. Otherwise, the data packet is
returned to the data stream if the data packet is not intended for local
distribution.
