摘要:
基于中粒度质量可分级(medium grain scalable,MGS)视频编码方式及其结构,研究利用残差数据整数变换后能量分布不均匀的特点,提出MGS片层数据重要性的评估方法,并将其用于指导编码端的容错编码.利用修复层间结构的差错隐藏方式,达到在带宽受限或网络环境不稳定情况下提高视频码流质量的目的.通过对MGS片层数据重要性测试以及信道差错控制测试,验证MGS片层重要性估计的准确性较传统差错控制方法有改进,可有效提高解码端数据恢复质量.
Abstract:
After integer transformation of residual data, data energy will be of unequal distribution. According to this feature, a method to estimate the importance of MGS slices is proposed.This method is used to supervise error resilient in encoding part. By constructing compensated MGS slices, an error concealment method is also proposed. It can improve the video quality when the bandwidth is limited or the network environment is unreliable. Experiments show that the MGS slice method and the error control method are superior to the traditional methods.
