A genre recording control method using KBPS in a TVCR.

As is well known, in response to video and audio signals transmitted from each broadcasting station, video / audio signals for a specific channel selected by the viewer are tuned, and the video / audio signals are reproduced to process video / audio output. For example, about 60 channel bands are allocated to televisions that are outputted through the apparatus, and general TV broadcasts, cable broadcasts, cable TV broadcasts, and false broadcasts are provided as the channel bands.

In addition, the broadcasting station providing the broadcasting program according to the above broadcasting codes the broadcasting program information about the broadcasting time, the audience, the broadcasting program title, the broadcasting program genre, and the like for the one week or one month broadcasting program to be broadcasted by the broadcasting station. By converting the data into a vertical retrace of the broadcast signal, the receiver can easily acquire information on the broadcast program that is scheduled to be broadcasted by the broadcasting station. This method is commonly used in Korean broadcasting program system (KBPS) or BPS ( broadcasting program system).

In particular, the system of the KBPS signal applied to the KBPS is adjacent to the videotext data line (ie, the 11th to 14th lines) in the teletext data line and the like transmitted in the video blanking period as shown in FIG. 1. And the KBPS signal includes data indicating the date / month / hour / minute when the broadcast program currently being viewed or the broadcast program that is broadcast within one week or one month is broadcasted, and the broadcast program The broadcasted country code data and program source code data indicating the type of the broadcast program are included.

Here, the program source code data is composed of a hexadecimal code indicating the type of a broadcast program as shown in FIG. 2. For example, according to the code data, '43' is a broadcast for 'economic, industrial, and financial'. It is a program, '4A' is a broadcast program for 'news', and '5B' is a broadcast program for 'drama'.

As a result, the TV side can obtain information on the genre, the broadcast time, and the like of the broadcast program or the broadcast program on a weekly and monthly basis through the KBPS code data.

In addition, as the functions of electronic products are complexed, a televideo (TVCR) composed of a combination of a television function and a video cassette recorder function has become common.

On the other hand, when a predetermined broadcast program is recorded using the corresponding televideo, the broadcast programs are sequentially recorded on the video tape T in the order in which the recording is required. In this case, the broadcast program is recorded on the video tape T. If the recording can be performed according to the genre, it is possible to play and watch only the program for the specific genre desired by the user at the time of playing the video tape T, thereby providing a considerable convenience to the user.

Accordingly, the present invention has been made in view of the above circumstances, and by genre by using KBPS in a TVCR, a program of the same genre can be stored in a divided genre signal recording area by dividing a video tape by genre to set a genre recording mode. The purpose is to provide a recording control method.

According to an embodiment of the present invention, a recording control method for each genre using KBPS in a TVCR detects KBPS code data from a broadcast signal and then analyzes and takes information on a broadcast program being received. What is claimed is: 1. Analyzing a genre for a broadcast program based on the KBPS data detected from the broadcast signal when the genre recording mode is set; A second step of determining whether a control signal for a genre classification code corresponding to the genre analyzed in the step is detected while fast rewinding after rewinding the video tape T; A third step of recording a predetermined video / audio / control signal on the video tape T from the recordable area of the genre classification area when the control signal for the genre classification code is detected; When the recording operation ends, a genre recording control method using KBPS in a TVCR is provided, which has a fourth step of recording a predetermined control signal at the end of recording.

Hereinafter, a genre-division recording control method and a reproduction control method using KBPS in a TVCR according to an embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG. 6.

First, with reference to the flowchart shown in FIG. 6, a method for controlling genre recording using KBPS in a TVCR according to an embodiment of the present invention will be described in detail.

When the genre recording setting mode is set by the genre recording setting button 10a configured in the control signal input unit 10 (step 50), the control unit 12 performs video tape T on which the genre recording is performed on the CRT screen. OSD processing of the setting screen for inputting the playable time of the video and the genre to be split-coated (step 52), and the hysteresis in response to the setting screen indicates the playable time of the video tape T. In the following description, the signal recording example of the video tape T shown in FIG. 5 is illustrated as an example, and the genre is news → drama → sports → show with the playable time of the video tape T being 120 minutes. When input in ascending / ascending order, the controller 12 divides the video tape T by 40 minutes based on the playable time, and divides the video tape T into each division point A, B, C, and D. And the code corresponding to the number of recorded programs. Signal recording and / or using a first control head configured for reading portions 48 will be recorded by two bits.

In one embodiment of the present invention, the code corresponding to the genre classification code and the number of recorded programs will be described as 2 bits, but it can be applied to more bits.

Through the above process, the controller 12 inputs '0000' at point A of the first region corresponding to 'news' and inputs '0100' at point B of the second region corresponding to 'drama', Input '1000' at point C in the third area corresponding to 'Sports' and '1100' at point D in the fourth area corresponding to 'Show / Entertainment' (see Fig. 5). The genre classification code is recorded in the genre classification code storage section 38 (step 54).

When the genre recording mode is set by the genre recording mode button 10b of the control signal input unit 10 in the above state, the controller 12 activates the KBPS code detector 34 to activate the image IF module 22. KBPS code data is detected from the video signal outputted from the video signal, and then the detected KBPS code data is applied to the controller 12 (step 62).

Accordingly, the controller 12 analyzes the genre for the broadcast signal based on the KBPS code data (step 64), and then controls the tape driving mechanism 46 to rewind the video tape T. After the rewind operation is completed (step 66), the video tape T is fast rewound (step 68), based on the control signal applied from the second control head configured in the signal recording / reading unit 48. It is determined whether the genre analysis code of the genre analyzed in step 64 is detected (step 70).

For example, if the broadcast genre analyzed in step 64 is 'sports', the control unit 12 may determine that the genre classification code corresponding to 'sports' is '10' based on the genre classification code stored in the genre classification code storage unit 38. After recognizing that the control signal according to the genre classification code corresponding to '10' from the signal recording / reading unit 48 is determined.

As a result of the determination, if the control signal corresponding to the genre classification code '10' is not applied from the signal recording / reading unit 46 (NO in step 70), the process proceeds to the step 68 to perform the video tape T. While performing the fast-forward operation, when a control signal corresponding to the genre classification code '10' is applied from the signal recording / reading unit 46 (YES in step 70), a code signal applied subsequent to the genre classification code is applied. The number of recorded programs is analyzed on the basis of (step 72).

If the code signal is '00', the program number analysis result recognizes that no signal is recorded in the third area, and updates and stores the code signal to '01' (step 74). If it is determined whether the signal has been read (step 76), and the result of the determination determines that the number of programs analyzed is '0', it is determined that the control signal corresponding to the number of programs has been read (YES in step 76). The related device is controlled such that the control signal according to the recording operation is recorded while recording the video / audio signal of the broadcast signal of the channel tuned by the tuner 18 from the point C of the video tape T (step 78). .

That is, the controller 12 controls the A / V switching unit 24 so that the video / audio signal of the broadcast signal output from the video / audio IF modules 22 and 20 is converted into the video / audio signal processor 50. Then, the signal recording / reading unit 48 and the tape driving mechanism 46 are controlled to perform the recording operation for the broadcast signal.

While performing the recording operation through the step 78, the control unit 12 determines whether a predetermined genre classification code is detected through the second control head configured in the signal recording / reading unit 48 (step 80). For example, when the first program is recorded in the third region and the D region of the video tape T is approached, the genre classification code '11' recorded in the D region is read by the second control head and the controller ( 12), the control unit 12 controls the video / audio signal processing unit 50, the signal recording / reading unit 48, and the tape driving mechanism 46 according to the determination result (YES) in step 80. To stop the recording operation (step 82).

However, unlike the above case, if the first program is recorded up to the point C ′ of the third area in step 80 and the recording is terminated by the control signal input unit 10 (step 84), the control unit 12 Controls the first control head configured in the signal recording / control signal recording unit 48 so that a predetermined control signal '1' is recorded at the point C '(step 86).

On the other hand, if the genre of the broadcast signal for recording in step 64 is analyzed as 'drama', and genre classification code '01' corresponding to 'drama' is detected in step 70, the control unit 12 determines the genre classification code. The number of recorded programs is analyzed on the basis of the code signal '10' applied subsequently, and the result shows that the number of recorded programs is two (see FIG. 5).

Then, the controller 12 proceeds to step 74 and updates and records the number of programs recorded at the point B of the video tape T as '11' to record the control signal corresponding to '0111' as a whole. Proceeding to step 76, it is determined whether only the number of program control signals analyzed in step 72 have been read.

In this case, since the number of recorded programs analyzed in step 72 is 2, the controller 12 determines whether the control signal has been read twice, by the first control head of the signal recording / reading unit 48. When the control signal is read at the point B ′ of the video tape T, the control unit 12 proceeds to step 88 according to the determination result in step 76 (NO) to control the tape driving mechanism 46 to control the video. After fast forwarding the tape T, the flow proceeds to step 76 above.

If the control signal is read at the point B ″ of the video tape T by the first control head of the signal recording / reading unit 48 in the process of fast-winding the video tape T in step 88, the control unit According to the judgment result in the step 76 (YES), the process proceeds to the step 78 and re-executes the operations from the above steps 76 to 86.

Accordingly, programs in which the genre corresponds to 'news' are sequentially stored in the first region, and programs corresponding to the drama' drama 'are sequentially stored in the second region, and genre is' Programs corresponding to 'Sports' are sequentially stored, and programs corresponding to 'Show / Entertainment' of genres are sequentially stored in the fourth region.

As described above, according to the genre recording control method using KBPS in a TVCR according to an embodiment of the present invention, the user can divide and store the video tape on the video tape T according to the genre when performing the recording operation. In the case of reproducing (T), only a broadcast program for a specific genre can be selectively viewed.
