First Claim
1. An apparatus for communicating graphics between at least two remotely-located computers across a computer network comprising:
- an input for receiving a video signal output from a graphics card of a source computer;
a memory for storing discrete units of the video signal;
a compression circuit for compressing a plurality of the discrete units into a compressed video signal;
a network interface circuit coupled to both the compression circuit and the computer network, the network interface circuit configured to format and communicate the compressed video signal over the computer network to a remote computer; and
an output coupled to the computer network.

Abstract
The present invention is generally directed to a system and method for communicating graphics across one or more computer networks. Broadly, the system comprises an input for receiving a video signal, a memory for storing discrete units of the video signal, and a network interface circuit coupled to both the compression circuit and the computer network, the network interface circuit configured to format and communicate the compressed video signal over the computer network to a remote computer. In a preferred embodiment, the system also includes a compression circuit for compressing a plurality of the discrete units into a compressed video signal. In accordance with another aspect of the invention, a method is provided that receives a video signal, converts the video signal into a format suitable for communication over a computer network, and communicates the converted video signal across the computer network to a remote computer.
