摘要 PCT No. PCT/JP88/01203 Sec. 371 Date Jul. 18, 1989 Sec. 102(e) Date Jul. 18, 1989 PCT Filed Nov. 29, 1988 PCT Pub. No. WO89/05548 PCT Pub. Date Jun. 15, 1989.The present invention relates to a receiving apparatus which can be used in receiving a satellite broadcast by using a cable television system. The receiving apparatus uses a double-super type converter or tuner (2) having a first frequency-conversion portion (15) and a second frequency-conversion portion (19). A conversion output terminal (G) for feeding a signal to a BS tuner (5) is provided at the output side of the first frequency-conversion portion (15). A BA signal converted into a UHF band or a superhigh band is fed to the first frequency-conversion portion (15) through a cable, so that, after frequency conversion, a BS-IF signal is taken out from the conversion output terminal (G). Thus, the BS-IF signal can be fed to the BS tuner (5) without using any special up-converter.
