SATELLITE RECEIVING SYSTEM

PURPOSE:To reduce parts and to add a function by converting the respective demodulation outputs of plural decoders into high frequency signals with different ground broadcast wave bands respectively, mix-outputting them and superimposing video or sound messages from an external part. CONSTITUTION:Plural decoders 14, to which an intermediate frequency signals are supplied from a distributor 13, supplies the outputs of them to a PF converter 15. The converter 15 converts them into high frequency signals different from a groung broadcast wave and outputs a mixer 16 to output to an external part. These functions are housed in a basket body 17. Besides, a message input device 25 to superimpose a video message and a sound message is connected to a changeover switch 26. The video message and the sound message are transmitted to the converter 15 with substituting for a station selection demodulating output by the control of the switch 26. Thus, a function to transmit the message profitable in an ordinary level can be added to the common system of a small scale.
