我国电视事业的不断发展,人民精神需求的不断提高,用户对广播电视的实效性和技术性也有了更高的要求。由于我国幅员辽阔,电视节目又是经过延时之后才能传输信号,因此,很容易出现节目信号差、声画错位等现象。这就需要详细研究和分析电视精密同步广播技术,以此促进广播电视信号的有效传输,实现电视事业的综合发展。
The continuous development of China’s television industry, the continuous improvement of the needs of the people, users of radio and television’s effectiveness and technical also have higher requirements. Due to the vast territory of our country, television programs can only transmit signals after a delay. Therefore, it is very apt to have the phenomena of poor signal of programs and misplaced sound and pictures.
