IDB-1394 (ITS Data Bus-1394)

 Differential pulse code modulation (DPCM)
The value of each pixel of an image generally is related to that of adjacent pixels and tends to have a value close to those adjoining it. In DPCM, taking advantage of this tendency, the values are estimated for pixels adjacent to those targeted for compression, and the degree of difference from the actual pixels is encoded. Since processing is done on the pixel level, it is easy to streamline.
