In particular, the end-to-end error propagation distortion on pixel level precision is analyzed based on temporal concealment and channel error rate. Subsequently, a new general transmission distortion estimation model for various temporal concealments is proposed.
首先介绍了视频编码中率失真(Rate-Distortion，R-D)优化的基本思想，讨论了宏块(Microblack，MB)编码模式选择所涉及的R-D优化问题；在综合考虑差错扩散、时域掩盖以及信道误码等基础上，从像素级对端到端的视频传输差错扩散失真情况进行了详细分析，提出了一种新的涵盖各种时域差错掩盖方法的通用传输失真度估算模型。
