A video receiving tuner relating to the present invention comprises an input terminal for receiving video reception signals that are digitally modulated, a front-end block for amplifying the video reception signals fed thereto from the input terminal and selecting a signal of one channel as a selection signal from among the amplified video reception signals, a digital demodulation circuit block for demodulating the selection signal into a digital signal, a re-modulation circuit block for modulating a carrier wave having a predetermined frequency by the digital signal so as to produce a re-modulation signal, a transmission circuit block for processing the re-modulation signal fed thereto from the re-modulation circuit and outputting a resultant signal as a radio signal, an antenna for transmitting the radio signal, and a casing for enclosing the front-end block, the digital demodulation circuit block, the re-modulation circuit block, and the transmission circuit block.
