Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to teletext equipment, and more particularly to an improved timer programming device for teletext programs in video equipment.

[Prior Art] For example, as shown in FIG. 3, a teletext device includes an adapter unit 10 that mainly performs teletext input processing, and
Each includes a video tape recorder section 12 for recording and reproducing the contents of the teletext, and a display section 14 for displaying the teletext.

For example, in Europe, when teletext is displayed on the display section 14, a time display 16 is displayed in the upper right corner of the screen as shown in FIG. 4 (Al).
The signal format of the first line of the page is shown in the same figure (B).
As shown in the synchronous byte section 18. It includes an address/control byte section 20, a display character code section 229, and a time display section 24. Of these, the time display section 2
4, a time display 16 is performed.

The teletext device shown in FIG. 3 operates as a whole, and also operates as a normal television or the like.

By the way, in Europe and elsewhere, there is a program guide on a predetermined page of Teletext, and a recording timer reservation system using this has been put into practical use. First, in the case of manual programming, the operation shown in FIG. 5(A) is performed.

In the figure, first, the operator performs a key or button operation for program setting (step S1). Then, the screen of the display unit 14 changes to the program set mode (step S2).
In this state, perform the necessary button operations to set the start time, end time, etc. of the desired program (step S3). After the timer reservation is completed, the predetermined button operations are performed again, and the screen on the display unit 14 is returns to the original menu screen (step S4).

Next, in the case of automatic programming, the operation shown in FIG. 6B is performed using the above-mentioned teletext program guide. In the figure, first, the operator operates a button for automatic program setting (step S5), and then a table of contents page, which is a teletext program guide, is displayed on the screen of the display unit 14 (step S6).
.

The operator selects the desired program by operating the cursor on the screen (step S7), and the teletext device then searches for the 4-digit numerical data and month/day data of the corresponding program from the program guide. It is done. These data are treated as broadcast start time and end time 0/day data of the corresponding program.

After the above program selection operation, when the operator performs a predetermined button operation (step S7), a program check mode is displayed on the screen, and the broadcast date of the selected program starts blinking (step S7). S8), the operator checks the set data (step S9), and if they are incorrect, corrects them (step S10゜5ll).
.

Next, if the set data is correct, the operator instructs the data store (step 512).
, the set data is stored and the automatic programming of the timer is completed. After this, pressing a button returns the display to the menu screen.

Problems to be Solved by the Invention C] However, the above-described timer programming method has the disadvantage that it does not work well when the time of the teletext and the time of the video tape recorder section 12 do not match. 0 For example, when receiving teletext from another country using satellite etc., if daylight savings time is in effect, the broadcast time of the teletext and the reception time of the receiving teletext device There may be a time difference between.

For example, if there is a one-hour time difference between the teletext broadcast time in country A and the reception time in country B on the side of the teletext device that is trying to receive it, the search data for the teletext program guide will be displayed as is. This causes the inconvenience of recording a program that is one hour earlier (or one hour later) than the desired program.

The present invention has been made in view of the above-mentioned problems.Even if there is a time difference between the reception time of the teletext device and the broadcast time of the teletext to be received, the present invention allows the operator to perform special time difference correction work. It is an object of the present invention to provide a timer programming device for a teletext device that can perform timer programming without problems and prevent erroneous recording.

[Means for Solving the Problems] One of the present inventions is a timer programming device that sets a timer to receive a desired teletext program and automatically receives and records the program. Teletext time extraction means for extracting broadcast time data on the teletext being broadcast; video setting time extraction means for extracting reception time data set in a video tape recorder section on the teletext receiving side; The present invention is characterized by comprising a comparing means for comparing the time data extracted by the time extracting means and determining whether there is a time difference between the two.

Another invention is characterized in that, in addition to the above-mentioned invention, data correction means is provided for correcting the reception time of the program based on the comparison result by the comparison means.

[Operation] According to the present invention, broadcast time data is extracted using time data included in teletext being broadcast. On the other hand, the reception time data set in the video tape recorder of the teletext device on the receiving side is also extracted.

These time data are then compared to determine the time difference between the two.

Furthermore, if there is a time difference, the reception time data of the program whose timer is set is corrected by the amount corresponding to the time difference.

[Examples] Examples of the present invention will be described below with reference to the accompanying drawings. Note that the same reference numerals are used for the same components as in the conventional example described above.
