Abstract
A method and system for video motion compensation in which an overall interframe motion vector is divided into a relative block motion vector and a subblock motion vector. Image reconstruction is achieved by adjusting the delay between the synchronization pulse and the start of the pixel data according to the subblock motion vector, and accessing stored data from memory according to the relative block motion vector. Accessing memory in a block-quantized format ensures that page mode accesses are confined to the same memory row.
