利用普通电话线路传送彩色电视图象有广泛意义。本文分析了影响传输时间和图象质量的一些主要问题,提出采用分量编码方式结合压缩编码技术,可以有效地压缩存储量及传输时间,文中具体介绍了一种基于上述原理自行研制成功的数字彩色静止图象传输系统,该系统在主要性能上达到国际上同类产品水平。
The use of ordinary telephone lines to transmit color television images has a wide range of meanings. This paper analyzes some of the main problems that affect the transmission time and image quality. It is proposed that the component coding method combined with the compression coding technology can effectively compress the storage capacity and the transmission time. In this paper, a digital color Still image transmission system, the system in the main performance reached the international level of similar products.
