  1. 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

    模擬實驗表明，本方案能在無噪通道中有效降低編碼器端8240位元組的打包開銷和2 . 70kbit的輸出比特數以及0 . 33kbps的比特率，而在有噪通道中可使解碼輸出重構視頻圖像的視覺質量得到一定程度的提高，亮度分量峰值信噪比可增加近1db 。
  2. Simulation has shown that the proposed scheme can achieve more accurately in similarity examination than scheme which proposed by [ 102 ]. so the bit number of coded video stream was decreased about 22. 95 percent and thus the compression ratio was improved. although the coding cost was increased about 8. 25 percent by using proposed scheme

    模擬實驗表明，與文獻[ 102 ]方案相比，提出的方案雖然增加了約8 . 25的編碼器編碼耗時，卻有效提高了對視頻序列突變幀的檢測精度，從而進一步降低編碼器端輸出編碼視頻流的比特數達22 . 95左右，在基本不影響重構視頻信息視覺質量的同時提高了編碼器的壓縮效率。
  3. Compare the performance of various manufacturers codecs, including coded video bit stream syntax verification, continuous real - time histogram of video code types, and calculated performance parameters

    比較各個製造商編解碼器的性能，包括編碼的視頻比特流句法驗證，視頻代碼類型的連續實時直方圖，以及計算后的性能參數。
