基于TMS320DM6467的H.264自适应错误掩盖并行解码算法
H.264 adaptive error concealment parallel deocder algorithm on TMS320DM6467
摘要
Abstract
For the problem that the real-time decoder is very sensitive to the packet loss, an adaptive error concealment algorithm which does not increase the complexity of decoder is proposed. Based on senary change infomation and motion features of neighboring regions, the method adaptively selects proper concealment algorithm. Based on DM6467 hardware architecture, the pipeline design and performance optimization are completed, experimental results show that the error concealment significantly improves the video quality by 1.87 dB respectively compared with current error concealment algorithm, and achieves real-time result.关键词
