VIDEO DECODER AND METHOD FOR MOTION COMPENSATION FOR OUT-OF-BOUNDARY PIXELS

摘要

Methods and systems for decoding motion compensated video. In the decoding process a virtual predicted block is defined within memory to hold the pixel values of a reference block used in motion compensation with respect to a macroblock being reconstructed. If the reference block includes out-of-boundary pixels from the reference frame, the corresponding pixels within the virtual predicted block are padded using the boundary values of the reference frame. This avoids the need to pad the entire reference frame.
