针对H.264的参考模型JM中P帧差错隐藏算法的不足,设计了改进的P帧差错隐藏方案。介绍了该方案中算法的理论基础及实现原理,并基于JM86平台对改进方案和原方案进行了对比测试,验证了改进方案具有一定的优越性。
Aiming at the shortage of P-frame error concealment algorithm in H.264 reference model JM, an improved P-frame error concealment scheme is designed. The theoretical basis and implementation principle of the algorithm in this scheme are introduced. The improved scheme and the original scheme are compared and tested based on the JM86 platform, which proves that the improved scheme has some advantages.
