BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a recording device that makes a recording reservation using a w view code.

[0002]

2. Description of the Related Art There has been proposed a video cassette recorder (hereinafter, referred to as a VCR) for making a recording reservation using a show view code. FIG. 3 shows an example of such a VCR. The show view code is also called a VCR plus or G code.

In the VCR shown in FIG. 3, when a user inputs a show view code of a program desired to make a recording reservation by operating a key input circuit 5 or a remote commander 6 of the VCR main body while viewing a TV program guide magazine or the like, the VCR main body is activated. Microprocessor 3 decodes the show view code, and sets the recording start date and time, the end time of the program, and the channel of the tuner circuit 2 corresponding to the show view guide channel in the reservation memory 10 as the recording reservation information. . Then, when the current date and time information generated by the clock 8 reaches the date and time set in the reservation memory 10, the microprocessor 3 sends a tuner control signal for the tuner circuit 2 to receive the reserved channel, and the video recording circuit 4 A control signal for setting the recording mode is sent. When the tuner circuit 2 succeeds in receiving the broadcast in accordance with the tuner control signal, the tuner circuit 2 transmits a data signal such as an AFT signal to the microprocessor 3.

At the time of the above-described recording reservation, a data table 9 is referred to in order to convert a show-view guide channel (hereinafter simply referred to as “guide channel”) into a channel selected by the tuner circuit 2. The channel corresponding to the selected position in the contents of the data table 9 is set by, for example, an automatic channel preset of the tuner circuit 2. The automatic channel preset scans the reception frequency of the tuner circuit 2 from, for example, a lower frequency to a higher frequency, and registers a channel on which a television signal can be received as a preset channel in a data table.

On the other hand, the association between the channel selection channel set in this way and the guide channel is performed by the user through the key operation of the key input circuit 5 or the remote commander 6. In the case of performing the operation by the key operation of the remote commander 6, first, as shown in FIG. Check which station is being broadcast. Although not shown in FIG. 3, it goes without saying that the video signal received by the tuner circuit 2 is supplied to the monitor television 12.

Next, as shown in FIG. 5 (a), the remote commander 6 corresponds to the position 1 broadcast station while viewing the correspondence list of the broadcast stations and guide channels published in the television program guide magazine 13. Enter the guide channel number. At this time, the screen of the monitor TV 12
5 by the on-screen display circuit 11.
A screen for setting the guide channel of position 1 as shown in (b) is displayed.

By performing the above operations for all the selected positions of the tuner circuit, the selected channels of the tuner circuit 2 are associated with the guide channels in the data table 9 of FIG.

[0008]

However, in the case of a conventional operation of associating a selected channel with a guide channel in a VCR, the user erroneously assigns the same guide channel to the selected channels of two or more broadcasting stations. There was a risk of setting.

When the guide channel setting is erroneously performed, the microprocessor 3 in the VCR main body converts the guide channel obtained by decoding the show view code into a channel selected by the tuner circuit 2. Sometimes it is not possible to convert to the correct channel. As a result, there is a problem that the user cannot record a program for which recording reservation is desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to the VCR shown in FIG. 3 will be described in detail with reference to the drawings. FIG. 1 shows a monitor TV 12 in a VCR to which the present invention is applied.
Shows an example of an image displayed on the screen. In this embodiment, when the user operates the keys of the remote commander 6 to set the guide channel, the broadcast of the selected channel corresponding to each position is superimposed on the guide channel setting screen. The user checks the broadcast station by watching this video, and looks at the correspondence list of the broadcast station and the guide channel published in the TV program guide magazine 13 as shown in FIG. Enter the number of the guide channel corresponding to the broadcasting station. FIG. 1 shows a screen for setting the guide channel of the position 1.

After the setting of the guide channel at the position 1 is completed, the guide channel at the position 2 is set in the same manner, and the guide channels up to the position 50 are sequentially set.

Next, a process for prohibiting the setting of the same guide channel for the selected channels of two or more broadcasting stations will be described. FIG. 2 shows a guide channel setting process of the microprocessor 3 of the VCR body.

First, in step S1, it is determined whether or not the input guide channel is equal to the guide channel of the position on the data table. If they are equal, the process is terminated; if they are not equal, the next step S
Move to 2. In this step, if the input guide channel is the same as the guide channel of the position in the data table, the subsequent processing is omitted.

In the next step S2, it is determined whether the input guide channel is 0 or not. If it is 0, the input guide channel 0 is written in the table. Here, the input guide channel being 0 means that the guide channel at that position is reset.

If the guide channel number is not 0 in step S2, the read position is set to 1 in step S3, and the guide channel corresponding to position 1 in the data table is read in step S4.

Then, in the next step S5, it is determined whether the read guide channel is equal to the input guide channel, and if they are equal, an error display is performed in step S9. As a result, duplicate registration of guide channels that have already been registered can be avoided.

On the other hand, if the read guide channel is not equal to the input guide channel, the read position is incremented by one in step S6. Then, in step S7, it is determined whether or not the reading position has exceeded a preset maximum value (= 50). If not, the process returns to step S4. On the other hand, if it exceeds the preset maximum value (= 50), the input guide channel is written to the position where the current guide channel of the data table is set.

As described above, in this embodiment, every time a guide channel is input, all positions in the data table are searched to detect the presence or absence of the same guide channel. Was written to. Here, the position at which the guide channel is currently set, that is, the position at which the input guide channel is written, is held in a register (not shown) connected to the microprocessor.

Although the reading position is sequentially changed from a small value to a large value in the above embodiment, the reading position may be changed from a large value to a small value. Also,
Instead of reading out all 50 positions, it may be configured to read out only the positions for which the selected channel is set. Further, in the above-described embodiment, the broadcast video selected by the tuner circuit is superimposed on the guide channel setting screen. However, after displaying this video on the entire screen for a certain period of time, the display is switched to the guide channel setting screen. May be. Further, the present invention can be applied not only to a VCR but also to a device for recording a video signal on a hard disk or a magneto-optical disk of a computer.

[0023]

As described above in detail, according to the present invention, the input guide channel information is determined before determining whether the input guide channel information matches the guide channel information stored in the data table. To determine whether the input guide channel information is equal to the corresponding guide channel information at a predetermined position on the data table, and determine whether the input guide channel information is information for resetting the corresponding guide channel information. Depending on the input guide channel information, the registration process of the data table can be performed quickly, and the registration of the guide channel information is not performed repeatedly.
When setting a reservation for a broadcast program, the guide channel information can be converted into one and only correct channel selection information, and a normal recording reservation can always be made.
