Centralised interactive graphical application server

摘要

A system for processing a plurality of graphical programs on a centralized computer system whereby the images produced by the programs are compressed and transmitted to a plurality of remote processing devices where they are decompressed. Compression assistance data (CAD) is produced by intercepting instructions outputted by the programs and the CAD is then used in the compression step.

主权项

1. A system for producing compressed image data comprising:
i) an image data compressor; ii) an instruction interception module; iii) a graphics processor module (GPM) accessible by the instruction interception module; iv) memory accessible by the image data compressor and the GPM;such that operation of the system causes the system to perform at least the following steps:
a) intercepting processor instructions by the instruction interception module; b) identifying at least one of the intercepted processor instructions having an influence on a co-ordinate associated with the image data; c) generating compression assistance data (CAD) or compression assistance instructions (CAI) or a combination thereof that are responsive to the identified graphics instruction, the CAD comprises information relating to the co-ordinate of at least one pixel of a plurality of pixels of step (d); d) processing at least one of the intercepted processor instructions by the GPM to generate a plurality of pixels to be stored in the memory; and e) processing at least a portion of the plurality of pixels using at least part of the CAD or at least part of the CAI or a combination thereof to generate compressed image data.
