随着LSI技术的进步,大容量汉字ROM集成电路的成本迅速下降,在我国发展信息传送效率较高的代码方式电视文字广播的可能性日益增大。本文提出了一种适用于我国汉字传输特点的代码方式电视文字广播试验方案;介绍了据此方案研制的一套简易节目制作,播出和接收实验系统;并给出其实验结果。
With the advancement of LSI technology, the cost of large-capacity Chinese character ROM integrated circuit is rapidly declining, and it is more and more likely that the development of information transmission in our country will be more effective in the form of television teletext. In this paper, we propose a test program of TV text broadcasting which is suitable for the transmission of Chinese characters. A set of simple program production, broadcasting and receiving experimental system is introduced. The experimental results are also given.
