Description: 在数字电视终端MPEG II 解码器测试中，解码能力测试是一个很关键的环节，即验证在前端输入码流满足TR 101 290 标准的前提下接收终端能正常解码，输出同步的视音频模拟信号。PCR 抖动
是影响接收终端解码的关键因素。本文深入探究了PCR 的功能和物理意义，并在分析PCR 抖动原因及其
测试参数的基础上，讨论了基于波形、幅度和频率三个参数的PCR 抖动仿真模型，并且根据实际测试终端解码器的需要，提出了具体的参数设置方法。-Terminals in the digital television decoder MPEG II test, the decoding ability of the test is a key link in that verification in the front-end input stream to meet the standard TR 101 290, under the premise receiving terminal to normal decoding, the output synchronization of video and audio analog signals. PCR jitter is the impact of receiving a key factor in decoding terminal. PCR This article explores in depth the function and physical meaning, and the reasons for the analysis of PCR jitter and test parameters on the basis of the discussion based on the waveform, magnitude and frequency of the three parameters of simulation model of PCR jitter, and test terminals based on the actual decoder the needs of specific parameter setting method.

Description: 运动估计是视频编码的关键技术，其最基本的原理是利用相邻帧间的时间
相关性，通过预测来减少时间冗余度。在实际编码中，为了节省码率，并不传
输每一帧的全部数据，而是利用运动估计求出每一帧与其预测参考帧之间的差
值。运动估计越准确，差值的分布越趋近与零，差值块的能量越小，经过变换、
量化和熵编码后所产生的码流的比特位率也越少。因此，运动估计搜索的准确
程度直接影响到了编码的压缩性能。
-Motion estimation is the key to video encoding technology, its basic principle is the use of the adjacent time frame relevant, through the forecast period to reduce redundancy. In the actual code, in order to save bit rate and does not transfer all the data of each frame, but the use of motion estimation for each frame obtained with the prediction of the difference between the reference frame. Motion estimation more accurate, more closer to the margin and the distribution of zero, the smaller the energy difference between blocks, after transform, quantization and entropy coding of the code produced by the bit stream bit rate is less. Therefore, the motion estimation search accuracy of the direct impact on the performance of the compression coding.
