摘要
讨论和比较了 MPEG— 1 ,Motion— JPEG,H.2 63视频压缩标准的特征 ,及其在分布式远程视频监控系统中的选用原则 ,研究了视频实时回显技术。针对不同视频标准的图像帧回放时间控制策略给出了上屏控制的具体算法 ,提高了抗干扰能力和算法的鲁棒性 ,最后对各种视频压缩和回显进行了对比试验 。
The features of the video compression standards MPEG- 1,Motion- JPEG and H.2 6 3and the principles of selection for use in the distributed rem ote video m onitoring system are discussed and compared.The video real- tim e display back technique is studied,and specific algorithms are given for the onto- the- screen control in the light of the tim e control strategy for the im age fram e playback of different video standards,thus im proving the anti- interference capability and the robustness of the algorithm s.Finally,the comparative experim ents are made on video compressions and display back and the range of application suitable for rem ote visual m onitoring is given.
