    • A radio response system including a broadcast station, a satellite relay, a processing center, and a plurality of user terminals. Each user terminal has a broadcast receiver, a communications interface device, a controller and a data transmitter. The broadcast station broadcasts a program signal. The broadcast receiver receives the program signal. The communications interface device communicates the program signal to a user. The controller generates a user-data signal from identification information transmitted in connection with the program signal and/or timing, location and frequency information needed for identifying the program signal, and a user-input signal generated in response to the program signal. The data transmitter transmits the user-data signal at a carrier frequency as a transmitted-data signal. The satellite relays the user-data signal to the processing center.
    • 包括广播台,卫星中继站,处理中心和多个用户终端的无线电应答系统。 每个用户终端具有广播接收机,通信接口设备,控制器和数据发射机。 广播台广播节目信号。 广播接收机接收节目信号。 通信接口设备将程序信号传送给用户。 控制器从与节目信号相关的识别信息和/或用于识别节目信号所需的定时,位置和频率信息以及响应于节目信号而生成的用户输入信号,生成用户数据信号。 数据发送器以载波频率发送用户数据信号作为发送数据信号。 卫星将用户数据信号中继到处理中心。
