Abstract
A method for decoding a digital video sequence includes decoding a first picture in the sequence; reducing a data size of the decoded first picture by vector quantizing at least one component of the first picture, the quantized component selected from the luminance and chrominance components of the first picture; storing a reduced data size representation of the decoded first picture to a memory; reading a region of interest of the reduced data size representation of the decoded first picture; and decoding a region of interest of a second picture in the sequence according to the region of interest of the reduced data size representation of the decoded first picture.
