Decodes the data content by receiving the separation sync 34d for separating, the data slicer 34e for detecting the KPS data from the complex synchronization signal provided from the synchronization separating 34D, and the KPS data. And a program ROM that stores various program contents processed by the KBPS decoder 34a to provide an On Screen Display (OSD) signal to the second switch 34k. 34g), the system RAM 34 and the character font rom 34h, and the O / S signal provided from the second switch 34k to the D / A (Digital / Analog) converter or to the video output of the system. A switch Isis 34L for providing a signal, an AD converter 34i for converting an analog signal provided from the Ish 34L into a digital signal and providing the signal to the KPS decoder 34a, and an external caption section 4 ) And a 1.9 MHz low pass filter (34m).

A conventional system that allows reservation recording using such a signal in a VSI system having a KBPS data receiving function is introduced in Korean Patent No. 1305 (Publication No. 94-16194).

In this case, when the user sees the program identifier displayed on the newspaper, etc., and inputs as the reserved recording data, the system checks whether the scheduled recording is set as shown in FIG. After that, the identification code is extracted, and the reservation method is performed based on the start time, length, title, etc. of the program provided by the KBP signal data.

As described above, a function of performing a reservation recording by using a K reservation recording means is known. However, a function for automatically setting a time on the set side using such KBP data is not provided. It became.

An object of the present invention is to maintain the time of the set side by using the KB PS time data of a plurality of broadcast channels provided by the broadcasting station to improve the above problems by the time error of the set side in such a system The problem is eliminated.

According to the present invention, in order to achieve the above object, the system receives time data of a channel currently being broadcast and checks whether the current time is the same as the set time, and when the times are different from each other, changes the channel to time data. Receiving and adding the time data value from the previous channel broadcasting and the current time data value, and calculating the average value of these when m number of channels, then set the average value as the current time data KBPS time It is characterized by the time setting method of using KBPS in VSI system performed by the setting processing program.

100. KB PS time setting processing program

The KB PS time setting processing program 100 which can implement the time setting method of using KB PS in the VSI system according to the present invention is illustrated as shown in FIG. 5.

Here, the system receives the time data of the channel currently being broadcast (step 101), checks whether the current time is the same as the set time (step 102), ends when the time is the same, and changes the channel when they are different (step 102). 103).

Then, the time data of the corresponding channel is received (step 104), the time data value from the previous channel broadcasting and the current time data value are summed (step 105), and it is checked whether the number of channel receptions is m predetermined channels. In step 9), if the number of these reception channels is m, the average value is calculated (step 107), and then the average value is set to the current time data (step 108).

1 and 2, the system recognizes the current broadcast channel received through the tuner and the IF unit 38, and the microcomputer 34 uses the KBI PS decoder of the KPS unit 34. Decode the KBPS data recognized through 34a).

The microcomputer 31 fetches the present time data from the decoded data through the KBP decoder 34a and compares it with the set time provided by the timer circuit 33 on the set side. Receive a broadcast channel.

For example, when the random number m = 4, the plurality of broadcast channels receive four broadcast channels to extract time data, and thereafter, the sum of these extracted time data values divided by a random number recognizes the current time data. The value is then set to the correct current set-side time.

On the other hand, this operation is performed by the microcomputer 31 together with the KBP CS time setting processing program 100 of FIG. 5, which receives the time data of the channel currently being broadcast by the system, so that the current time is set to the set time. It checks whether the time is the same, and when the time is the same, ends and changes the channel when they are different (steps 101 to 103).

Then, the time data of the corresponding channel is received, the time data value from the previous channel broadcasting and the current time data value are summed up, and the number of channels received is checked by checking whether the predetermined number of channels m is m, and the number of these channels is m. The average value is calculated, and then the average value is set as time data on the current set side (steps 104 to 108).

In the present invention, when the current set-side time and the time data received through the KBPS data do not coincide with each other in the VSI system having the KBPS reception function, the accurate time is referred to by referring to the KBPS data of the plurality of broadcasting channels. Because of this, the problem caused by visual error in such a system can be improved.
