Zusammenfassung:PROBLEM TO BE SOLVED: To prevent unpermitted monitoring of an RF signal by storing an ID code signal, capturing a video image of a received video signal and a received audio signal extracted from a plurality of video and audio signals in a digital radio frequency signal in response to the ID code signal, generating the video signal, coding the video signal and the audio signal, superimposing the coded video signal and audio signal onto an RF carrier and transmitting them. SOLUTION: An antenna 100 of a receiver 90 receives a digital radio frequency RF signal 170 and a digital radio receiver 110 receives RF data. The digital radio receiver 110 converts the RF data into digital data. The digital data are transferred to a microprocessor 120, where the digital data are converted into audio data and video data and decoded. The digital audio data are transferred to a D/A converter 150, where the digital audio data are converted into an electronic signal, which is transduced into sound by a speaker 160. The digital video data are transferred to a display driver 130, which provides an output of a video image, which is displayed on a display device 140.
