- Abstract
- A redundant picture is one of the H.264/AVC tools for increasing error resiliency when video is delivered over error prone environments. We present a loss-aware redundant picture allocation method that determines whether the redundant picture is inserted for each primary coded picture or not. The determination is based on an error rate of transmission network and the distortion of decoded picture caused by the error. Simulation results showed that the proposed method alleviates the distortion and, thereby, it achieves higher quality of the decoded picture than the conventional methods, including the hierarchical redundant picture. In particular, the proposed method produces outstanding results at low bit rates; thus, the method is highly applicable to low bitrate wireless video transmission. © 2010 Society of Photo-Optical Instrumentation Engineers.
