Abstract
The present invention provides a method and system to conceal video errors due to lost packets in the transmission without incurring additional bandwidth usage. The present invention is to use current and previous frames to search for similar patches for the corrupted blocks in the current frame. The search process speed for locating the lost packets is significantly improved by incorporating a smart search concept. The concealment algorithm of the present invention can be implemented in GPUs and multi-core CPUs.
