The present invention relates to a detailed guide information recording apparatus, and more particularly, to a detailed guide information recording apparatus configured to record detailed guide information such as a special program or a movie in a Korean reservation recording system.

The Korean Broadcasting Program System (hereinafter referred to as KBPS) is a program for recording broadcast program reservation recording data on a television signal and inserting it into an arbitrary line during the vertical blanking interval. The transmitted signal refers to a television recording method that demodulates at a receiving side to perform scheduled recording and automatic time setting of a broadcast program.

The transmitted data includes Korean standard time information, daily program formation operation information, program information currently being broadcast, information for updating in the case of a continuous program, and information for canceling / changing / adding / preceding.

If you look at the main features of KBPS, you can perform accurate scheduled recording, preserve scheduled recording data after a power outage, set the time automatically, and record continuous programs. In addition, the program provides detailed guide information, classifies broadcast programs, and reserve recording check function.

In other words, the characteristics of KBPS is that even if the program is changed due to broadcasting stations, each program is given a unique code. Therefore, when the code data comes in without a time change, only the program corresponding to the code data is recorded. Even in the event of power failure, the reserved recording data is stored in the memory device, so that accurate scheduled recording can be executed even after the power failure returns, and when the standard time information of the station comes in, the current time information contained in the data packet can be automatically set in the VCR set. It is supposed to be.

1 is an exemplary view showing a screen selected by various keys of the KBPS remote control, two screens of (A) is the initial KBPS screen that appears when you press the K button on the KBPS remote control.

If program data is received in the initial state of KBPS screen for about 5 ~ 6 minutes, the screen like (B) appears.If you press △ and ▽ button of KBPS remote control key, the cursor moves up and down, and ◁ and ▷ button. Is used to change the date.

If you move the cursor to the program you want to record and press the setup button among the KBPS remote control keys, the screen will appear as shown in (C) .If the program you want to record is a daily soap opera, you need to record the program every day. The number of recordings must be changed continuously.

If you want to cancel the scheduled recording, press the O button. If you want to end the recording reservation, press the K button on the KBPS remote control key to switch to the broadcast screen.

On the other hand, if you press the sort button of KBPS remote control key while (B) screen is displayed, the screen as (D) will appear.If you press the number button by selecting the desired program number, it will be classified as the broadcasting date. Only program by appears.

For example, if you select the 1 button of the KBPS remote control key while the screen like (D) is displayed, only the news program is displayed for each time zone as shown in (E).

Also, the program with ⊙ on the screen like (B) contains detailed guide data. Move the cursor to the location of the program with ⊙ displayed, and press the detailed guidance button on the KBPS remote control key. Detailed guide information is displayed on the screen as well.

2 is a configuration diagram of KBPS data on a horizontal synchronization signal inserted during a vertical blanking period. The clock frequency of KBPS data is 5.7272 MHz, and the KBPS signal is composed of 36 words including 8 bits as one word.

Of the 36 words described above, the first and second words W1 and W2 are clock synchronizing signals for synchronizing the clocks of the decoder, the third word W3 is a byte synchronizing signal for data classification, and the fourth word W4 is transmitted. A field counter for checking the continuity of the signal, and the rest are data headers W5 to W10 and data W11 to W36.

FIG. 3 is a block diagram of a conventional Korean reserved recording system. Since data must always be input to the KBPS decoder 50, when a power is turned off, a specific video input is input from the first switching circuit 10a and the power is turned on. In this case, a Y / C video input via the video module comes in.

The input signal is sent to the synchronous separator 20 and the data slicer 30, and then the data slicer 30 outputs a standardized signal by comparing the level of the transmission signal with a predetermined reference level, and the synchronous separator 20 Is separated into a composite sync signal, a horizontal sync signal, and a vertical sync signal.

The separated synchronization signal is sent to the data slicer 30 and the KBPS decoder 50 to synchronize synchronization of data slices and to synchronize OSD (On Screen Display).

The digital data sliced by the data slicer 30 is input to the KBPS decoder 50 to be decoded.

When the KBPS decoder 50 gives an address to the program ROM 70, the data corresponding to the address is transmitted to the KBPS decoder 50, while the font of the character data is obtained from the font ROM 60.

The KBPS enable signal, the clock signal, and the KBPS DATA IN signal are provided by the VCR microcomputer 40. When the KBPS DATA IN signal is recognized, the KBPS decoder 50 outputs the KBPS video output.

In this case, the D / A converter 90 converts the digital data into an analog signal, and the final video output converted by the D / A converter 90 is output by the second switching circuit 10b.

In the conventional KBPS as described above, there is a problem in that detailed guide information included in a special program or a movie cannot be recorded, for example, a movie title, director, starring actor, movie plot, and the like.

Accordingly, an object of the present invention is to provide a detailed guide information recording apparatus in a Korean reservation recording system which is designed to record detailed guide information of a program to be scheduled and recorded.
