Abstract

PURPOSE:To secure reception of the broadcast bands of all channels by converting the frequency bands of all channels received through UHF within the converter and the VHF tuner into the frequency band of the idle channel and then connecting the converted frequency band to the antenna terminal of existing receiver. CONSTITUTION:The VHFTV signal obtained through antenna 8 is amplified 3 at VHF tuner 1 and then mixed 5 with local oscillation 4 which is higher than the desired reception frequency by the 1st intermediate frequency. And the 1st intermediate frequency signal is obtained through the VHF tuner with the frequency conversion given to both the video and aural signals at the channel reception time. The UHF signals obtained through antenna 9 are processed and drawn out in the same way. Bothe the video and aural carrier waves of the obtained 1st intermediate frequency signal are inverted to each other in terms of position to the TV broadcast wave. The intermediate frequency signal is mixed with prescribed local oscillation frequency 6 to draw out the 2nd intermediated frequency signal which is higher than the 1st intermediate frequency. This frequency is set to the idle channel frequency of the UHF or VHF of the corresponding region, and as a result the picture reception of all channels becomes possible only by the channel selection through the converter.
