Abstract
A method, system and computer program for decompressing video data, storing the compressed video data in such a way that random access is possible and the data can be mapped efficiently into existing memory systems and interface protocols. The compression is accomplished via lossless compression using an algorithm optimized for video data. Due to the compressed format, data transmission consumes less bandwidth than using uncompressed data and prevents degradation in the decoded video.
