Abstract
The digital/analog television signal receiving set 10 includes a tuner 12, and the tuner 12 receives television signals of ATSC system and NTSC system. In the case of automatic scanning, a virtual channel table with respect to television signals of ATSC system capable of being received is stored in the memory 28. A channel number of television signals of NTSC system capable of being received is stored in the memory 28. Successively, it is detected whether or not an analog television channel described on the virtual channel table stored in the memory 28 can be received. When it is possible to receive the analog television channel, the channel number of the television signal of NTSC system is deleted from the memory 28. However, when it is possible to receive the analog television channel, the analog television channel included on the virtual channel table is deleted from the memory 28.
