Abstract
In MPEG-4 video, Motion Adaptive Intra Refresh (MAIR) encodes a motion area macroblock in intra mode, thereby preventing the error propagation. Motion area is selected by difference of between current macroblock and previous macroblock. An effective implementation of the AIR is to reduce the maximum refresh time and estimate the error prone macroblock. However in the case or the MAIR, unnecessary macroblock can be encoded in intra mode. in this paper, a bitrate AIR is proposed that reduces the maximum refresh time by estimating the error prone macroblock more efficiently.
