Abstract
Compact satellite TV receiving unit for communal installations, characterised in that the integrated internal unit comprises the satellite receiver, audio and video processor, IF modulator, vestigial bandpass filter, IF/channel converter and interchangeable single-channel amplifier units, the receiver compiling the signal input to the internal unit as a radio-frequency signal of intermediate frequency, in that the audio and video processor inputs the signal as baseband video signal and a series of audio-modulator carriers at FM, the modulator receiving the in-band signal at IF, in that the vestigial bandpass filter filters the signal, the converter unit comprising an oscillator able to generate a signal of higher frequency in order to mix it with the previous one, a signal at the desired frequency being obtained, in that the interchangeable single-channel amplifier comprises an input bandpass filter compatible with the elimination of unwanted signals, and with the option of connecting in the internal unit a decoder in substitution for the audio and video processor in order to allow decoded signals to be viewed.
