Abstract
A system ( ) which encodes and decodes video signals in accordance with a compression standard, such as H.263, efficiently stores and retrieves motion vectors associated with the signals. An encoder ( ) and a decoder ( ) each use a motion vector storage and retrieval circuit ( ) which addresses a respective SRAM array ( ). Advanced Prediction Mode for a video signal is implemented by storing only a minimum number of motion vectors by eliminating storage of motion vectors which are not needed for a real-time current calculation. Storage of selected top motion vectors associated with predetermined macroblocks of video information is avoided to gain a memory savings.
