Abstract
Methods and systems are provided that combine Dambrackas Video Compression (DVC) with block video compression. When transmitting video frames that are changing, they determine which blocks have changed from frame to frame and transmit the information for the blocks that have changed. They apply DVC compression to the blocks that have changed, reducing the amount of data to be transmitted from frame to frame. Information regarding the blocks that have changed may be the only information transmitted, and the information transmitted in the changed blocks is compressed using DVC commands. These methods and systems may realize a combined benefit of block compression systems and DVC systems. These systems provide a way to enhance DVC so that only blocks of video data that have changed are encoded and compressed and thus fewer bytes of data will be sent to the client.
