System and method for providing interframe compression in a graphics session
Abstract:
A visual server system (10) includes a visual server (12) that provides graphics images through execution of a graphics application (20). The server (12) includes a plurality of compression modules (28) that compress frames of a served visual for transport to a client terminal (14). The compression modules (28) keep track of differences between successive frames of a served visual and compress and transport only those differences to the client terminal (14). In this manner, traffic can be reduced on the network link between the server (12) and the client terminal (14) and a reduction in latency is achieved to enhance the interactive ability for the served visual. The client terminal (14) includes decompression modules (42) that can recreate the served visual in response to receipt of an update to the served visual which contains only the differences between successive frames.
