Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving channel auto-preset device used in a broadcast signal recording device for recording a broadcast signal by timer reservation such as an audio tape recorder, a video tape recorder, etc. In this case, the present invention also relates to a reception channel auto presetting device that can easily perform a channel presetting operation.

[0002]

2. Description of the Related Art Conventionally, in a broadcast signal recording apparatus for recording a broadcast signal by timer reservation such as an audio tape recorder, a video tape recorder, etc., one to a predetermined number of buttons provided on a main body cabinet or a remote control device are used. It is generally popular to directly select a channel recorded at a position from 1 to a predetermined number in a channel data memory for channel selection by pushing. In this case, 12, 16, etc. are adopted as the predetermined number.

In order to enable such channel selection, a conventional broadcast signal receiving apparatus employs a channel preset system. The channel preset method includes a manual method and an automatic preset method. The manual method is a method in which a user selects a channel that the user wants to receive and repeatedly executes an operation of storing it at an arbitrary position. On the other hand, the auto-preset method is a method in which the receiving circuit section automatically searches for channels and sequentially stores signal channels at positions.

Generally, in the VTR, a timer reservation system is employed in which reservation contents such as position, recording start time and recording end time are set by manual operation. In such a timer reservation method, no trouble occurs even if the conventional channel preset method is used. However, in recent years, VTRs using a code input type timer reservation system have become widespread. In this case, the number of channels is small in Japan, and VH
Considering the current situation where the F band is converted to the UHF band, it is indispensable that the channel data during the code input in the timer reservation is replaced with the position data designating the positions 1 to a predetermined number. Here, in television broadcasting, the same broadcasting is often transmitted in different channels depending on regions, especially in the UHF band. Therefore, when making a timer reservation for the code input method, the user has to manually preset the channel at a position determined by the region, which complicates the preset operation.

[0005]

In the conventional channel preset method described above, when the timer of the code input method is reserved, the user has to manually preset the channel at the position determined by the region. , The preset operation becomes complicated.

An object of the present invention is to eliminate the above-mentioned problems and to provide a reception channel auto-preset device capable of automatically presetting a channel at a position defined by a region by a simple operation.

[0007]

A reception channel auto-preset device according to the present invention is a reception channel auto-preset device for presetting channel data at a predetermined number of positions in a channel data memory for tuning. , A channel data memory for each area in which channel data corresponding to the predetermined number of positions is stored for each area, an area code input means for inputting a code indicating the area, and a code from this area code input means And a control circuit for causing the channel data for each region to read out the channel data in the indicated region and storing the read channel data in the position of the channel data memory for tuning.

[0008]

According to this structure, the control circuit reads the channel data of the area indicated by the code from the code input means from the area-specific channel data memory only by inputting the code indicating the area by the area code input means. Since it is stored in the position of the channel data memory for channel selection, the channel can be automatically preset to the position determined by the region by a simple operation.
