<P>PROBLEM TO BE SOLVED: To provide a conversion system capable of converting video signals of a program of digital television broadcast into broadcast signals of analog television broadcast, and transmitting the converted signals while suppressing an increase in the number of components. <P>SOLUTION: A terrestrial digital antenna 200 is subjected to impedance matching so as to be adapted to the reception of terrestrial digital broadcast, and the terrestrial digital antenna 200 and an analog broadcast antenna 500 connected to audio 400 capable of viewing analog television broadcast are disposed closely. A terrestrial digital broadcast receiver 100 extracts video and audio signals from a terrestrial digital broadcast signal received via the terrestrial digital broadcast antenna 200, converts the extracted signals into analog broadcast signals of a VHF band, and transmits the converted signals from the terrestrial digital antenna 200 to the audio 400. <P>COPYRIGHT: (C)2011,JPO&INPIT |
