摘要
近年来,视频通信在会议电视、视频电话、远程视频医疗、互动电视、远程视频教育以及网络视频游戏等业务领域中的应用越来越广泛,其应用质量在一定程度上取决于网络编码参数产生的限制码率、视频画面质量以及视频传输流畅度等重要指标。从视频源选取、编码方案参数的确定以及测试视频的输出等方面分析了网络视频通信编码方案的拟定,确定了编码方案的测试方法与评价方案。通过数据归档与解析,在不同的应用场景下需要进行相应的编码方案调整,以提高其适用性。
In recent years,video communication has been widely used in business fields such as conference TV,video telephony,remote video medical treatment,interactive TV,remote video education,and online video games,and its application quality depends to a certain extent on the generation of network coding parameters,limit bit rate,video picture quality and video transmission fluency and other important indicators.The formulation of the coding scheme for network video communication is analyzed from the aspects of video source selection,coding scheme parameter determination and test video output,and the testing method and evaluation scheme of the coding scheme are determined.Through data archiving and parsing,corresponding coding scheme adjustments need to be made in different application scenarios to improve its applicability.
