Network multimedia interface
First Claim
1. A multimedia network system for operation in conjunction with a data network and a computer having a video board which is connected to the system bus of the computer and which is further connected to an audio/video device, comprising:
- a high speed data bus;
a network interface board connected to the high speed data bus and further connected to a system bus of the computer and further connected to the data network;
whereinsaid video board is connected to the high speed data bus; and
said network interface board receives a plurality of data cells from the data network, formats said data cells into asynchronous signals and synchronous signals, routes said asynchronous signals within the data cells to the computer and further routes said synchronous signals to the high speed data bus.

Abstract
A multimedia network system (10) for connection to a computer (12) and a computer network (28). Asynchronous transmission mode cells on the network (28) are processed by a network interface board (22) with synchronous signals routed to an ISOBUS (26) and asynchronous signals routed through a packet memory (54) to the computer (12). Asynchronous signals are routed through the ISOBUS (26) to a video board (24) and converted for output to one or more audio/video output devices (36). Signals originating at one or more audio/video input devices (34) are processed through the video board (24) and the network interface board (22) to the network (28).
