Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiving apparatus for a video tape recorder (VTR), a television receiver (TV) or the like, which allows easy and reliable channel presetting.

[0002]

2. Description of the Related Art Conventionally, when setting a receiving channel on a VTR or TV, first check the broadcasting station that can be received by referring to "How to set the receiving channel" in the instruction manual of the purchased device, Had to set. This operation is an operation that is unnecessary after setting once, and it is complicated and difficult for general users because they are unfamiliar. Furthermore, if you do not know which broadcast you are receiving, VHF or UHF, or if you live in an area where you can receive broadcasts from multiple stations, which broadcast station is the best to receive. It is difficult to judge whether For this reason, in some cases, an electronic store may be asked to set the settings.

In recent years, as a presetting method, it is automatically set only by inputting the area code or telephone area code corresponding to the place where one lives, from the area code list shown in the instruction manual. I have to. In the case of this preset method, the number is input in the channel setting mode, and the reception channel such as UHF broadcast is added or changed. In addition, a purchaser in an area that does not have a number such as an area code sets the channel to be changed one by one after matching the area code closest to the area.

As described above, since the automatic setting method using the area code does not cover the whole country, it is necessary to change the receiving channel depending on the area. Further, when there are a plurality of transmitting stations, it may not be possible to set the area code or the area code, and if the setting of the receiving channel is wrong, the recording may fail if the device is a VTR.

[0005]

In the above prior art,
For general users, the operation is complicated and difficult because they are unfamiliar with the operation. Furthermore, if you do not know which broadcast you are receiving, VHF or UHF, or if you live in an area where you can receive broadcasts from multiple stations, which broadcast station is the best to receive. It is difficult to judge whether

Furthermore, since the automatic setting method using the area code does not cover the whole country, depending on the area,
It is necessary to change the receiving channel. Further, when there are a plurality of transmitting stations, it may not be possible to set the area code or the area code, and if the setting of the receiving channel is wrong, the recording may fail if the device is a VTR.

In view of the above problems, the present invention provides a highly reliable television in which channel presetting can be performed easily and surely, and as a result, the channel will not be mistaken during channel selection and recording will not fail. It is an object of the present invention to provide a John receiver.

Other configurations are the same as those in FIG.

According to this structure, when the television receiver is, for example, a VTR, at the time of timer recording,
If there is a bad reception on the broadcast channel of the program to be recorded and there are multiple broadcast stations (affiliated stations) of the same program, if there is a broadcast station with a good reception status other than the timer-set station, Since the broadcasting station is automatically preset immediately before the start of the timer operation, it is possible to switch to a station with a good reception state at the same time when the timer operation starts and to record in the best state. As a result, at the time of timer recording, it is possible to automatically preset and record only the broadcasting station channel having the best reception state among broadcasting station channels having the same broadcast content.
