随着社会经济、科学技术不断的发展,人们物质精神生活要求也越来越高,以往落后的信息通讯技术已经无法满足当今社会的需求。过去的数据广播需要信号线进行传播,且限于传播声音信号,然而随着技术的发展,数据广播已经实现了无线传播,并且可以搭载视频信号以及数据信号。调频多工广播技术的普及和应用,大大提高了信息传播的速度,节约了数据广播传输的成本。
With the continuous development of social economy and science and technology, people’s material and spiritual needs are also getting higher and higher. In the past, backward ICTs have been unable to meet the needs of today’s society. In the past, data broadcasting required signals to be transmitted, and limited to transmitting voice signals. However, with the development of technologies, data broadcasting has realized radio propagation and can carry video signals and data signals. The popularity and application of FM multiplex broadcast technology has greatly enhanced the speed of information dissemination and saved the cost of data broadcast transmission.
