多媒体通信终端系统涉及的技术是多方面的,它是一种综合性的技术,目前在试验多媒体通信终端系统的过程中,涉及到如下几个方面的关键性技术 一、数字信号处理技术 随着多媒体通信技术的口益发展,对多媒体数据进行快速检索、存储、传递和播放成为面临的主要问题。数据压缩技术就是解决这一问题的关键技术。数据压缩技术的研究,从1948年Oliver提出PCM(脉码调制)压缩理论开始,至今已有40多年的历史,压缩技术
The technology of multimedia communication terminal system is multifaceted. It is a comprehensive technology. At present, in the process of testing the multimedia communication terminal system, it involves the following key technologies: 1. Digital signal processing technology With the The development of the benefits of multimedia communication technology, the multimedia data to quickly retrieve, store, transmit and play as the main problems facing. Data compression technology is the key technology to solve this problem. Data compression technology research, from Oliver in 1948 proposed PCM (pulse code modulation) compression theory, has been 40 years of history, compression technology
