摘要

MPML是我们在之前的工作中提出的一种基于xml的MPEG视频编码方法。本文对在噪声信道环境下MPML编码码率与PSNR性能之间的权衡进行了全面研究。最初的MPML压缩算法已被修改为部分保护，以减少XML开销。提出了一种实现部分MPML保护的方案。仿真结果表明，基于mpml的纠错复原技术可以达到较好的无线视频传输性能。

MPML-based error-resilient wireless video transmission

MPML is an XML-based MPEG video coding method that was proposed in our previous work. A comprehensive study on the tradeoff between the coding bit rates and the PSNR performance with MPML under the noisy channel environment is conducted in this research. The original MPML compression algorithm has been modified for partial protection to reduce the XML overhead. A scheme to realize partial MPML protection is proposed. Simulation results demonstrate that the proposed MPML-based error resilient technique can achieve good performance for wireless video transmission.
