Decoding a JPEG in Java has acceptable speed so this codec -tries to exploit that feature. The algorithm first compares the last and the -new image and finds all 16x16 blocks that have a squared difference bigger than -a configurable threshold. Then all these blocks are compressed into an NxM JPEG. -The quality of the JPEG is inversely proportional to the number of blocks, this -way, the picture quality degrades with heavy motion scenes but the bitrate stays -more or less constant. -Decoding decompresses the JPEG and then updates the old picture with the new -blocks. - - -TODO: ----- -- make format extensible -- motion vectors -- do some real bitrate control
