Zusammenfassung: | PURPOSE:To simplify channel setting by providing plural decoders to which intermediate frequency signal are distributed within a same case body, converting respective demodulating outputs into high frequency signals with different ground broadcast bands respectively and after that, mix-outputting them. CONSTITUTION:Plural decoders 14, to which intermediate frequency signals are supplied from a distributor 13, demodulate them and output them to a RF converter 15. The converter 15 converts them into high frequency signals with difference ground broadcast bands respectively, mixes through a mixer 16 and outputs to an external part. These functions are housed in a same case body 17. A station selecting demodulator 18, a video signal processing part 19 and a sound PCM signal processing part 20 are built in the decoder 14. Station-selecting and demodulation are executed only on an individual assigned and specified satellite channel so as not to be duplicated in advance and video and sound signals are outputted by a base band from the processing parts 19 and 20. Thus, also an operation when resetting is executed adjusting to a vacant channel can be satisfied with the one button operation. |
