An effective video anti-error algorithm for H.264

A known problem in video streaming is that loss of a packet usually results into loss of a whole video frame. Error concealment is an effective way to solve this problem. A fast interactive anti-error algorithm based on motion tracking which suits for H.264 is proposed. In this algorithm, decoder firstly detects the error, and position of error blocks is feed back to encoder. Then encoder decides the areas that error possibly spread to with a motion tracking strategy. The possible areas are encoded in specific mode to avoid further propagation of error. The simulation result shows that error propagation can be prevented using proposed method of fast interactive anti-error algorithm based on motion tracking.
