    • 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. Inputting 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.
    • 一种用于多媒体网络中的服务节点的装置。 该装置具有数据分配器电路和解码器。 数据分配卡具有用于与数据流耦合的数据端口。 数据分配器电路具有用于确定数据流的数据分组的地址字段是否用于由分配电路局部分配给外围设备的关系码。 与分配电路通信的解码器具有虚拟信道滤波器,用于对地址字段进行过滤以将数据分组路由到至少一个数据端口,例如与外围设备相关联的数据端口。 提供一种电连接到数据端口的并入电路,以将具有关系码和虚拟信道码的地址值插入到从至少一个数据端口输入的数据中。 然后,引入器将从列表音数据端口输入的数据插入到数据流中。 在本发明的方法中,提供了具有多个数据分组的多媒体通信数据流的接口。 输入数据流的数据包,确定数据包的地址字段是否用于本地分发,如果数据包用于本地分发,则将数据包路由到数据端口。 否则,如果数据包不用于本地分发,数据包将返回到数据流。
