随着多媒体技术的飞速发展，人们对于可视电话的研究方兴未艾，但以前的研究工作基本上属于纯理论的，而且不同的系统之间不具备互连性，因此对于实际运用来说意义不是很大。该文针对国际通信联盟（ＩＴＵ）制定的Ｈ．３２４可视电话系统，提出了一个具体的实现方案，Ｈ．３２４标准虽然已经对整个系统特别是互连性进行了定义，但是仍然在理论和具体实现上给进一步研究留有限大余地。该文重点讨论软件实现的平台，音频和视频信号的采集软件的功能以及测试等问题。 With the rapid development of multimedia technology, the research on videophone is in the ascendant. However, the previous research work is basically purely theoretical, and the interconnection between different systems is not so significant for practical application Big. This article aims at the International Telecommunications Union (ITU) developed by H. 324 videophone system, put forward a concrete realization plan, H. 324 standard Although the entire system has been defined, in particular, the interconnectivity, but still theoretical and practical implementation of the study for much left. This article focuses on the software platform, audio and video signal acquisition software functions and testing issues.
