Differential vector quantization of real-time video
James E. Fowler, Stanley C. Ahalt · 2002
Describes hardware that has been built to compress video in real time using full-search vector quantization (VQ). This architecture implements a differential-vector-quantization (DVQ) algorithm and features a special-purpose digital associative memory, the VAMPIRE chip, which has been fabricated in 2 /spl mu/m CMOS. The authors describe the DVQ algorithm, its adaptations for sampled NTSC composite-color video, and details of its hardware implementation. They conclude by presenting images drawn from real-time operation of the DVQ hardware.>
