Abstract: A system and method for compressing video data. When a triplet of data values corresponding to a pixel differs sufficiently little from a previous, reference triplet, the difference is encoded using one of several encoding functions selected according to which of several criteria of similarity between the current triplet and the reference triplet is met. When none of the available criteria of similarity is met, the triplet is instead encoded using differential pulse code modulation with non-uniform quantization.
