日本的FM多工广播,在1988年1月由电气通信技术审议会就固定接收方式答询出台,同年8月由民间广播机构实用化。现正在进行固定接收方式数据部分的编码和适于移动接收的传输方式的开发。下面,以这次FM多工广播的技术方式为中心,并就美国和欧洲的FM多工广播及其利用形态进行解说。
In Japan, FM multiplex broadcasting was promulgated by the Council for Electrical and Telecommunications Technology in January 1988 on the fixed reception mode, and in August the same year it was put to practical use by the private broadcasters. Development of a code for a fixed reception mode data portion and a transmission method suitable for mobile reception are under way. In the following, we focus on the technology of FM multiplex broadcasting and explain the FM multiplex broadcast and its utilization patterns in the United States and Europe.
