- In improved uep scheme , the syntax elements belonged to luminance parts and chrominance parts was reassigned to different data partitions . those packets containing syntax elements belonged to luminance parts were got error protection at high level so as to guarantee their correctness during transmitting in error - prone network . simulation has shown that using proposed scheme , the packing tradeoff is decreased 8240 bytes in error - free channel and also the output bits and bit rate of coded video stream are decreased 2 . 70kbits and 0 . 33 kbps respectively
仿真实验表明，本方案能在无噪信道中有效降低编码器端8240字节的打包开销和2 . 70kbit的输出比特数以及0 . 33kbps的比特率，而在有噪信道中可使解码输出重构视频图像的视觉质量得到一定程度的提高，亮度分量峰值信噪比可增加近1db 。 - Then , the properties of generator and parity - check matrix of turbo codes are presented , the simulation results show that turbo codes are unequally protected . three kinds of constructions of unequal error protection turbo codes are introduced finally . the last chapter is the conclusion and further research issues
另外还给出了turbo码的生成矩阵和一致校验矩阵的形式和特点，论证了turbo码本身所具有的非均匀保护的特性，最后给出了构造非均匀保护turbo码的三种方法。 - This scheme firstly determined the operating mode of coded video stream in nal layer according to the current channel state before they were packed . the coded video stream operated under ssm in error - free channel so as to reduce the packing tradeoff and increase the coding efficiency . while in error - prone channel , they operated under dpm combined with improved unequal error protection ( uep ) scheme based on human eyes characteristic in order to elevate their robustness to channel error
该方案中编码视频信息在进行打包封装前，首先根据当前信道状态信息自适应地确定其在nal层中的工作模式，在无丢包信道中采用单数据片模式以降低编码视频流的打包开销，提高编码效率；而在丢包信道中采用数据分区模式以提高编码视频流对信道误码的鲁棒性能，同时基于人眼视觉特性，提出了一种改进的uep策略。
