Abstract
An audio-visual content delivery system includes an interface to communicate with a local area network (LAN). A packet processing circuit in the system may filter and route Ethernet packet data received from the LAN, to specific ports and/or queues without host processor intervention. The packet processing circuit may utilize a set of filter and routing mechanisms configurable in hardware to interpret various Internet Engineering Task Force networking transport protocols, and may transfer the packet data in a format recognized by a variety of consumer subsystems, each of which may be coupled to the packet processing circuit. The packet processing circuit may be implemented as a semiconductor device, and may allow encapsulated application data to be routed to a plurality of different types of application sinks or processors, forming a point-to-point or multi-point serial or parallel data stream over a standard transport covering numerous levels of the ISO data communications stack.
