Description

Continuous reservation recording method of VCR using KBPS data.

The present invention relates to a reservation recording method of a video cassette recorder (hereinafter, referred to as a VCR) using KBPS (Korea Broadcasting Program System) data, and more particularly, to a method of displaying information on a continuous scheduled recording program. .

KBPS data is one of broadcast methods that allows additional program data, text multicasting, and the like by inserting additional additional data in a vertical blanking period of a broadcast video signal.

That is, the scanning method performed to form one screen using a cathode ray tube or the like is divided into sequential scanning and interlaced scanning, and a method generally performed is interlaced scanning.

Interlaced scanning starts from the top left of the screen and scans sequentially, reaches back to the bottom center of the screen, and then goes back up again. Next, the scanning is completed by filling the gap that was previously scanned. That is, interlaced scanning is called interlaced scanning because it is spaced by one line, and it is called interlaced scanning. Since the screen at the end of one vertical scanning is called 1 field, 1 screen is composed of 2 fields in interlaced scanning. do.

In this interlaced scan, the electron beam needs to return from the bottom to the top of the screen. This is called vertical retrae. In this vertical retrace period, substantially horizontal scanning is performed continuously. However, since this period is not required as an image, a blanking signal enters, and this period is called a vertical blanking interval.

It is known that the vertical blanking period is composed of 21 horizontal scanning periods so that information such as text data can be duplicated at the appropriate position. KBPS refers to a Korean character multicasting format in which reservation recording and separate character information are transmitted in such a vertical blanking period, and the reservation recording and character display are performed according to the KBPS data. .

By using such KBPS data, it is possible to easily perform reservation recording of the VCR. One of the reservation recording methods using the KBPS data is a continuous reservation recording method.

In the continuous scheduled recording method, daily or weekly TV programs are added with KBPS data (the number of broadcasts of a continuous program) indicating that the program is a continuous program, and when a user designates one of these programs, the designated continuous program is automatically It's a way to record continuously.

On the other hand, even in the scheduled recording using KBPS data, when the video tape to be recorded in the VCR is not loaded or the recording prevention tab is attached to the loaded video tape, the recording is not performed.

In other words, the user thinks that after setting the continuous schedule recording using the KBPS data, all the set programs are recorded, but there may be a program that is not actually recorded, and it is very difficult for the user to check the unrecorded program. There is a problem of difficulty.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and an object of the present invention is to provide a continuous reservation recording method of a VCR using KBPS data that displays a program not continuously recorded when performing continuous reservation recording using KBPS data. .

The continuous reservation recording method of a VCR using KBPS data according to the present invention relates to a method of driving a VCR capable of reserved recording by KBPS data. Determining whether KBPS data corresponding to the program is included; If KBPS data corresponding to the reserved program is included, determining whether recording of a broadcast signal of a channel is possible; Recording the broadcast signal of the channel, if it is possible to record the channel's broadcast signal, and determining whether the KBPS data includes information on a program number indicating that the program is a continuous program; If the information on the number of programs is included, storing the information about the program and the number of programs; When the reception of the KBPS data for the reserved program ends, stopping the driving of the recording mode; And when the continuous recording check mode is set, displaying the stored programs and the number of programs.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

First, in order for the apparatus according to the present invention to perform a function, the above-described data should be transmitted by the broadcasting station as KBPS data. That is, the broadcasting station should transmit KBPS data or the like informing the type of the program being broadcast and whether the program is continuous (daily or weekly) or not (the number of times the program is broadcasted).

1 shows a VCR block diagram of the present invention in which reservation recording is performed using KBPS data transmitted from a broadcasting station.

As shown, the apparatus for carrying out the present invention includes a tuner 1, a microcomputer 2, a decoder circuit 10 and a signal processor 4, a deck 5 and a modulator 6.

In this configuration, the tuner 1 receives a broadcast signal of a predetermined channel under the control of the microcomputer 2, and the signal received by the tuner 1 is applied to the signal processor 4 and the decoder circuit 10, respectively.

In this case, the decoder circuit 10 may include the synchronous separator 11, the data separator 12, the decoder 13, the continuous memory 14, the memory 15, and the digital / analog converter 16. ). That is, the sync separator 11 separates the sync signal from the received broadcast signal of the tuner 1 and applies the sync signal to the decoder 13, and the data separator 12 separates the sync signal from the sync signal separated by the sync separator 11. KBPS data are separated and applied to the decoder 13.

The decoder 13 stores information on the KBPS data applied from the data separation unit 12 in synchronization with the synchronization signal at predetermined addresses of the memory 15, respectively, and stores the information on the KBPS data on the microcomputer 2. Is authorized. As can be seen from the description below, the microcomputer 2 may set the recording mode of the continuous program by the user, and if the KBPS data applied from the decoder 13 is for the program in which the recording mode is set, the signal processing unit 4 may be used. And the deck 5 are driven in the recording mode. In addition, the microcomputer 2 is for a program in which a recording mode is set in the KBPS data applied from the decoder 13, and if the information on the number of broadcasts is included in the data, the microcomputer 2 causes the decoder 13 to transmit the number of broadcasts. The information is controlled to be stored in the continuous memory 14.

In addition, when the continuous recording confirmation key of the key matrix 7 (not shown) is pressed as described later, the microcomputer 2 causes the decoder 13 to read information stored in the continuous memory 14 to perform digital / analog conversion. Control to apply to the unit (16).

On the other hand, the signal processor 4 is driven in the recording and playback mode under the control of the microcomputer 2, and in the recording mode, the video signal of the tuner 1 is recorded and applied to the deck 5, and in the playback mode. Is configured to reproduce the video signal of the videotape read out from the deck 5 and apply it to the modulator 6.

The deck 5 includes all the mechanical and electronic mechanisms of the VCR capable of recording the video signal of the signal processor 4 on the video tape by the video head or reading and outputting the video signal recorded on the video tape. The microcomputer 2 is configured to drive in the recording and playback modes, respectively.

The modulator 6 converts the signal of the signal processor 4 and the digital / analog converter 16 into a broadcast signal of a predetermined channel 3 or 4 under the control of the microcomputer 2, or outputs the tuner 1. Is output directly.

Fig. 2 shows a flow chart of the microcomputer 2 which implements the present invention in a VCR having the above-described configuration.

As shown in FIG. 2, the microcomputer 2 determines whether the power of the VCR is turned off in step S1, determines whether the scheduled recording start time is turned on, and turns on the power of the VCR at the scheduled recording start time (step S2). .

In step S3, the microcomputer 2 causes the tuner 1 to receive the broadcast of the reserved recording channel, and determines whether KBPS data applied from the decoder 13 is data for a program for which reserved recording is set ( S4) If reservation recording is set to KBPS data, the flow proceeds to step S5.

In step S5, the microcomputer 2 is in a state in which the signal processing unit 4 and the deck 5 can be driven in a recording mode (video tape is loaded, and a recording prevention tab is installed, and all possible recording states are possible). If it is possible to record after determining whether the recording is possible, the video signal of the tuner 1 can be recorded on the video tape by driving the signal processing unit 4 and the deck 5 in the recording mode (S6). If you do, turn off the VCR and terminate the process.

At this time, the microcomputer 2 determines whether the KBPS data from the decoder 13 includes information on the number of programs indicating that the program is a continuous program after performing the step S6 (S8), and includes the information on the number of programs. The decoder 13 then stores information about the program and the number of programs in the continuous memory 14 (S9).

Then, when the reception of the KBPS data for the reserved program is terminated (S10), the microcomputer 2 causes the signal processing unit 4 and the deck 5 to stop the recording mode and turn off the power of the VCR (step S11). S12).

On the other hand, as a result of the determination in step S1, when the VCR is powered on, the microcomputer 2 determines whether the continuous recording confirmation key of the key matrix has been pressed (S13), and when the continuous recording confirmation key is pressed, the decoder ( 13) to decode and store the information stored in the continuous memory 14 (S14).
