  Abstract

To transmit MPEG-2 video on an errorneous channel, a number of error control techniques arc needed. Especially, error concealment techniques which can be implemented on receivers independent of transmitters arc essential to obtain good video quality. In this paper, prediction of motion vector and an adaptive boundary matching algorithm are presented for temporal error concealment. Before the complex BMA, we perform error concealment by a motion vector prediction using neighboring motion vectors. If the candidate of error concealment is not satisfied, search range and reliable boundary pixels are selected by the temporal activity or motion vectors and a damaged macroblock is concealed by applying an adaptive BMA. This error concealment technique reduces the complexity and maintains a PSNR gain of 0.3 - 0.7dB compared to conventional BMA.
