The hybrid video error concealment algorithm with low complexity approach

The transmission of the multimedia data under Internet environment has been wildly used in many applications in the recent. However, the video data is very sensitive to the transmission error caused by packet lost. This induces decoded video data with error propagation and makes the video quality very poor. In this paper we proposed the hybrid error concealment algorithm with low complexity approach. By use of the bidirectional frame as the referenced frame, error propagation in inter frame coding mode can be reduced largely. Our approach has the advantage of better video quality within a small search range and low complexity requirement.
