The Constructional Designing Approach Of High-Definition Videoconferencing System

The videoconferencing, as a new telecommunication product has developed for tens of years. Videoconferencing system is based on the TV technology, and code technology and net communication technology development, and the standard usually adopt includes: H.261,H.263,H.320,H.323,H.243 and T.120. With the implementation of code technology of MPEG standard and the improvement of basic facilities for network, and now it is suitable for us to develop the high-definition videoconferencing system. This article, by introducing the high-definition videoconferencing's design process and application process, this article leads a discussion to the main problems that we often meet during the application and cure.As the video conferencing system's theory foundation ,this article first analyses the current development of videoconferencing. Introduced the H.261, H.263, H320, H323,H243&T120. And as the main study object , this article analysis the combine,application and the carework of the high-definition videoconferencing system and at last give out an available construction designing way of it.
