Abstract
BDC-1 is a low-complexity algorithm to compress digital video in real time in a visually lossless way for transmission over display links. The algorithm is based on DPCM, with a number of improvements. The decoder infers prediction modes and quantization levels based on previously received data. The entropy coding facilitates decoding at 3 pixels per clock at low cost. The decoded image quality is superior to many state-of-the-art low-cost compression schemes, particularly on pathologically difficult and computer-generated content.
