Multi-broadcast recording device, has demodulation unit demodulating transmitted intermediate frequency signal corresponding to broadcast system in response to broadcast selection signal

摘要

The device (100) has a processing unit (110) for processing broadcast signals of broadcast systems in response to a channel selection signal into intermediate frequency signals. A filter (120) lets the intermediate signals via the unit over a preset frequency band. An amplifier (130) amplifies the intermediate signals with a preset amplification and transmits one of the intermediate signals. One broadcast system is selected in response to a control signal, and a demodulation unit (140) demodulates the transmitted signal corresponding to the system in response to a broadcast selection signal.
