An efficient, integrated solution for processing input transport streams, such as MPEG2 streams. MPEG packets are routed from an input circuit card to one or more various target processor cards in a chassis. The processor cards provide functions such as transcoding, multiplexing, splicing, scrambling, and so forth. Each processor card also has a router for routing a received packet to one of a number of available hardware processing paths. Customized IP-type routing is used to encapsulate and route the packets to the processor cards, where a destination address field provides source information regarding a received packet, such as a source slot and port, and a packet identifier (PID). The routers are configured by a system host computer to efficiently use the available resources of the processor cards. <IMAGE> |
