2. Description of the Related Art The conventional technique is, for example, the actual Kaihei 1-91
As described in Japanese Patent No. 330, a storage area of a memory for automatically storing information corresponding to a reception frequency of a broadcast radio wave that is swept and automatically tuned to a broadcast radio wave that is automatically tuned or manually tuned. When the storage area of the memory for manually storing the information corresponding to the reception frequency is separately provided, and the information corresponding to the reception frequency of the broadcast radio wave automatically swept by newly sweeping the broadcast radio wave is automatically stored, In some cases, information corresponding to the reception frequency stored by manual operation is not rewritten.

[0003]

However, in the prior art, the storage area of the memory for automatically storing the information corresponding to the reception frequency of the broadcast radio wave swept and automatically tuned to the storage area of the memory. The information corresponding to the manually tuned reception frequency of the broadcast radio wave is provided separately from the memory storage area for manual operation, and the information corresponding to the automatically tuned reception frequency of the broadcast radio wave is automatically swept by newly sweeping the broadcast radio wave. It was possible to prevent the information corresponding to the reception frequency that was stored by manual operation from being overwritten when it was memorized, but the broadcast wave was swept in multiple areas and the reception frequency of the broadcast wave was automatically tuned. There is a problem that the corresponding information cannot be stored in the memory for each of a plurality of regions. Also, in some regions, the broadcast radio waves that are automatically tuned are weak, and if there are broadcast radio waves that cannot be received due to the weather, it is not possible to prevent the reception of the broadcast radio waves that are automatically tuned and stored. There was a point.

The present invention has been made in view of the above points, and tuner setting information (hereinafter referred to as a preset channel) corresponding to a reception channel of a television broadcast that is automatically tuned by sweeping radio waves of a television broadcast for each of a plurality of regions. Information) is automatically stored sequentially for each region, skipped stored preset channel information is set, skip information is set, and preset channel information for which skip information is not set is selected to receive TV broadcasting. It is intended to provide a broadcast receiving device and a control method thereof that can perform the above.

[0005]

In order to achieve the above object, the present invention stores preset channel information of a television broadcast that is automatically tuned by sweeping radio waves of the television broadcast and selects stored preset channel information. In a broadcast receiving device for receiving a television broadcast, a plurality of storage means for storing preset channel information of the television broadcast for each region and a selection means for selecting one of the plurality of storage means are provided. Preset channel information of a television broadcast that is automatically tuned by sweeping radio waves is sequentially stored in one of the plurality of storage means selected by the selection means, and one of the plurality of storage means selected by the selection means is stored. Select the preset channel information stored in one to receive the television broadcast.

[0006] Further, a preset device having a skip information setting means for setting the skip information for skipping the preset channel information, setting the skip information in the preset channel information stored in the storage means, and setting the skip information. Skip channel information,
Select the preset channel information for which skip information is not set to receive the TV broadcast.

[0007] Further, the preset channel information is provided with a skip information canceling means for canceling the skip information of the preset channel information, cancels the skip information of the preset channel information stored in the storage means, and cancels the skip information. To be able to select.

By these means, the radio wave of the television broadcast is swept for each of a plurality of regions, the tuner setting information corresponding to the automatically tuned reception channel of the television broadcast is automatically stored in each region, and the stored preset channels are stored. Skip information can be set by setting skip information, and preset channel information for which skip information is not set can be selected to receive a television broadcast.
