The present invention relates to a method of executing a scheduled recording of a television broadcast using a videoplus code, in particular, a recording time data set using a videoplus code and a PDC (program delivery) transmitted together with a broadcast program by a broadcasting station. The present invention relates to a method of automatically executing PDC recording by video plus that automatically executes PDC recording even when a certain time difference occurs between data.

Currently, a reservation recording method using PDC data (hereinafter referred to as PDC recording) has become common as a method for conveniently performing reservation recording of a program broadcasted on a television. PDC recording is a method of performing a scheduled recording of a corresponding program using data corresponding to the broadcast date and broadcast start time of the program among the PDC data transmitted together with the program from the broadcasting station (hereinafter referred to as first data). That is, when the user inputs the video plus code, the microcomputer in the VCR compares the first recording data with the reservation recording date and start time set by the video plus code (hereinafter referred to as the second data). If the data matches, recording is performed. At this time, the video plus code is made by encoding the scheduled start time and end time of the program, and is described in a newspaper or a magazine for the user to conveniently record the program.

However, such a video plus code sets the start time and the end time of the program in order to accurately record the program even when the start time and end time of the program are delayed due to commercials. It is generally made with a margin of 1 to 2 minutes. Therefore, in order to execute the above-described PDC recording using the video plus code, the user has to inconvenience again to adjust the reservation recording time to match the above-described first data.

The problem of the PDC recording method using the conventional video plus will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing an example of a screen configuration at the time of reservation recording by a general video plus. When the user selects a mode for executing scheduled recording by video plus, the screen shown in FIG. 1A is displayed on the monitor. At this time, if the user inputs a video plus code (for example, 12345 in FIG. 1) of a program to be recorded, a screen like FIG. 1 (b) is displayed on the monitor. That is, if the actual broadcast time of the program to be recorded is "10:00 to 10:30", Video Plus Code is created with the actual broadcast time and a fixed time (two minutes here). It is set to "09: 58-10: 32". In addition, at the bottom of the screen, a message for selecting whether to execute PDC recording is displayed and the PDC display blinks. At this time, if the user wants to execute the above-described PDC recording, the user should turn on the PDC using the PDC key. When the PDC is turned on, the screen as shown in FIG. At this time, a warning phrase (CHECK STRT TIME IN THE TV GUIDE) is displayed on the lower part of the screen of FIG. When the PDC recording is performed, the recording can be performed only when the first data and the second data are the same. Therefore, when the first data and the second data are different, the second data is corrected to match the first data. To do that. At this time, if the user does not modify the second data to match the first data, not only the PDC recording but also the normal recording cannot be executed. That is, in the case of PDC recording, the first data transmitted from the broadcasting station when the program actually starts is [DATA: 29/03, START TIME: 10:00], while the video plus code is used to enter the VCR set. The reserved second data is represented as [DATA: 29/03, START TIME: 19:58], so the two data are different and PDC recording cannot be executed. In addition, since the PDC recording is selected, the normal recording which counts the scheduled recording start time and executes recording is also not executed.

As described above, in the conventional recording method using the video plus code, the user should decide whether to execute the PDC recording, and select the ON or OFF mode of the PDC. It was inconvenient to check the actual start of the program again and to adjust the first and second data to match.

Accordingly, an object of the present invention is to automatically turn on the PDC system when the video plus Scott input, and compares the first data and the second data to the same data when the time difference between the two data is within a certain range. The present invention provides a method for automatically executing PDC recording by video plus, which enables the user to automatically execute PDC recording only by inputting a video plus code.

PDC recording automatic execution method by video plus according to the present invention for achieving the above object is a method of executing a scheduled recording of a broadcast program using a video plus code, when the video plus code is automatically input to the PDC system A step of turning on, a first judging step of performing a PDC recording or a general recording according to whether or not PDC data is included in the input broadcast signal, the first data and the video plus of the time and date at which the program is started among the PDC data; In the second judging step of judging whether or not the second data with respect to the scheduled recording start time set by the code coincides with each other, when the difference between the first data and the second data is within the preset range, Determination of the third judging step, and the second judging step or the third judging step of judging the data to be the same Based on by a first data and a 2 PDC recording step of executing a data match or to execute the PDC recording for the program when the data turn out to be the same.

Hereinafter, a method for automatically executing PDC recording by video plus according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram showing an example of the screen configuration in the case of executing the reserved recording according to the method of the present invention. As shown in the figure, when the user selects a mode for executing scheduled recording by video plus, the screen as shown in Fig. 2A is displayed on the monitor. At this time, when the user inputs the video plus code (12345 in FIG. 2) of the program that the user wants to record, the screen as shown in FIG. 2 (b) is displayed on the monitor. In other words, when the user enters the video plus code, the PDC is automatically turned on to execute the PDC recording and general recording.

The method of automatically executing PDC recording by video plus will be described in detail with reference to FIG.

3 is a flowchart illustrating a method for automatically executing PDC recording by video plus according to the present invention. When the user inputs the video plus code of the program to record, the PDC system is automatically turned on (step 10).

In performing PDC recording, a search must first be made to detect PDC data. At this time, the search for detecting the PDC data is performed for a period of time (hereinafter referred to as PDC search period) within a predetermined time before and after the reserved recording time of the program. For example, if the reserved recording time of the program is "March 29 10: 00-10: 30", the above-mentioned PDC search section is March 28 28: 00-28: 00 ( 34 hours), etc., to perform PDC search with sufficient time interval.

If the reserved recording time is set by the video plus code, first, it is determined whether the PDC search period is reached (step 20). When the PDC search period is reached, a search for whether PDC data is included in the input broadcast signal starts (step 30). In this case, PDC recording or general recording is selected according to whether PDC data is loaded in the currently input broadcast program (step 40). First, if the PDC data is not included in the currently input broadcast program, the VCR system determines whether the start time of the corresponding program has been reached in order to execute general recording (step 80). When the start time of the program is determined as described above (step 80), general recording is executed (step 90), and when the time is not reached, the PDC data is searched by feeding back to the first step. When the PDC data is detected as a result of the determination in step 40, it is first determined whether the first data described above among the detected PDC data and the second data with respect to the recording start time set by the video plus code coincide with each other (50). step). At this time, if the first data and the second data coincide, PDC recording is immediately performed (step 70). If the first data and the second data coincide, the two data are judged again according to the following equation (step 60). ).

[2nd data ≤ 1st data ± 5 minutes]: Same data ---- (formula)

As shown in (Formula), when the difference between the first data and the second data is within 5 minutes, it is determined that the two data are the same and PDC recording is performed (step 70), and the difference exceeds 5 minutes. It is determined that the two data are different and feeds back to the above-described search step of the PDC data. For example, in the case where the first data is "March 29 10:00" and the second data is "March 29 09:58", the above-described expression (09:58? 10; 00 ± 5 minutes], the first data and the second data are regarded as the same data, and PDC recording is performed. Once the PDC recording starts, the VCR system considers the actual PDC data (1 March 29 10:00) in the recorded broadcast program as the correct PDC data and performs all processing. Scheduled recording can be performed.

As described above, the method of automatically executing PDC recording by video plus according to the present invention automatically executes PDC recording only when a user inputs a video plus code when a scheduled recording of a program is executed using the video plus code. To help. Therefore, the present invention performs the PDC recording of the program only by the input of the video plus code without the user's separate operation, thereby providing the convenience of reservation recording.
