Description

VSIAL's Highlight Recording Process and Processing Method

The present invention relates to a reservation recording processing means using KB PS data in a VSI system having a KB PS character broadcasting reception function, which is particularly impressive for a sports relay during reservation recording using such KB PS data (highlights). Only scenes) can be selectively scheduled.

Text broadcasting is intended to express text or picture data reconstructed from code data on the screen of a television receiver for broadcasting service of digital data transmitted in the structure of an analog signal or by using a digital modulation system. have.

Although the character broadcasting system uses the field blanking interval of the horizontal synchronization signal in the current television signal in most cases, there are various choices for extending the data utilization task to occupy all the effective scanning lines in the television signal. .

In such a system, an example of a data line, a data unit, a data packet, and the like on the back porch of a horizontal synchronization signal of a television is illustrated as shown in FIG. 3.

In Fig. 2A, A is a line synchronization signal, B is a color burst, C is bit synchronization, and D is a data line.

In Fig. 2B, E denotes byte synchronization, F denotes data units, and in Fig. 2C, G is a prefix, H is a data block, J is a data packet, and K is used as a suffix signal where it can be adapted. .

In addition, such a character broadcasting system is used by most of the developed countries such as West Germany, Japan, the United States, France, the United Kingdom, and Korea, and they use scan lines and frequencies (for example, 625/50, 525/60) in each country. There are several kinds of different text broadcasting systems in use.

On the other hand, Korean character broadcasting is designed to insert KBIPS signal data into the back porch side of the horizontal synchronization section of the video signal and use various kinds of information.

For example, the KBPS signal is a signal type that is multiplexed and allocated to a horizontal scan line signal of a video signal as information such as a program provided by the broadcasting station side formed as shown in FIG. A word and a data block are included, and one word is formed in units of 8 bits (1 byte).

In addition, the KBPS defines a countermeasure for various matters that may occur in transmitting a program such as preceding, delayed, canceled, or modified program broadcasting by referring to the program list broadcast on the TV receiver screen. By simply and quickly entering the weak input, only the actual main broadcast part of the broadcast program (removing parts other than the main broadcast, the middle, and the back main broadcast) can be accurately executed.

It displays one week (or four weeks) of broadcasting program on TV screen according to the provision of reservation recording method, and when you want to record the program you want, use the cursor to move the program and then put the program in system memory. Accurate reservation recording is possible even if the program start time is fluctuated due to broadcasting station conditions.

The transmission data at this time is made as follows.

1) Standard time information of broadcasting station

2) Program information currently being broadcast

3) Broadcasting station name (7 characters)

4) 1 to 4 weeks program information

5) Classification data by program type

6) Program Details / Subtitles

7) Program Delete Information

And the like.

In addition, the service function using the data as described above can be displayed in the broadcast order guide, automatic reservation recording (active reservation recording at the time of power failure or when the broadcast start time is changed), reservation recording of the changed program, confirmation of the contents of the drug, etc. Has the service function of

Also, in such a system, after the user has made the reservation recording setting, the system microcomputer periodically compares the reservation contents set by the user with the current broadcast and performs the reservation recording execution operation when the two data match.

In such a KB PS method, a related art related to the present invention is known to be able to process a simple reservation recording in a VSI system using a KB PS signal, which is called a K reservation recording means. An example of a VSI system utilized as is shown in FIG. 1.

Here, the microcomputer 31 for controlling the VSI system, the servo control unit 32 for driving control of the motor on the system deck side, the remote control unit 33b and the set side connected wirelessly to the remote control transmitter 33c The recording signal is taped from a timer circuit 33 to which the key portion 33b is connected, an audio circuit 35 for processing a reproduction or audio recording signal in the system, and an RF signal provided from the tuner and the IF unit 38. A video circuit 37 provided on the side or processing a reproduced video signal lamp, a DMSS unit 36 controlled to provide an audio signal in a normal state at the time of double speed reproduction on the system deck side, a KB PS, etc. KPPI to decode data such as character and graphic of the screen and to display the character indicator of the menu screen for character, graphic display and function selection of various information on the screen Tuning a signal received from the seubu 34, and the antenna consists of a tuner and children F unit 38 for generating a signal of an intermediate frequency, a power circuit 39, such as providing power to the system.

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. 4, and if the scheduled recording is set, whether the scheduled recording is executed again. After that, the identification code is extracted, and then the reservation process 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, in the case of sports broadcasting among reservation contents among various professional contents provided by the K means, a specific content is not recorded. When there was a need to record and watch only a part (for example, when a goal was scored during a soccer game), it was not desirable because there was no means to reserve only that part.

For example, when a user of such a system needs to watch and record only the important part of a soccer game without having to see the entire contents, the whole scene only plays a predetermined scene, so that only a specific scene can be seen. It was difficult to avoid the hassle and inconvenience of reworking for viewing.

An object of the present invention is to eliminate the waste of tape for unnecessary recording in such a system by selectively reserving only the highlight portion that is an issue during the recording of sports, such as sports relay using KBPS broadcast to improve the above problems It can be used for this purpose because only certain parts can be generated during playback.

The present invention is connected to the tuner and the IF of the system to implement the above object, the KB PS decoder for detecting the KB PS data, and the audio received by being connected to the audio system amplifier of the tuner and IF The signal detection unit detects the signal level and compares the contents set in the reserved recording with the current reception contents provided to the KPS decoder to recognize whether the data match. On the other hand, the signal level is detected from the audio signal detection unit to detect the highlight signal. The back side includes a microcomputer of a control operation that executes a reservation recording, and a signal detection unit that receives a control signal from the microcomputer at the time of the reservation recording and detects an output signal level of an audio system and provides it to the microcomputer. Highlights of the recording processing system It is.

Another feature of the present invention is to check whether the system is in the scheduled recording mode, and if it is in the weak recording, whether to highlight recording, and in the case of highlight recording, the system is placed in the pause mode (Pause) mode from the audio signal detection unit Detecting the input signal level, checking whether the audio detection level is an arbitrary value x and the time is greater than y, and performing the recording mode when the condition is satisfied, and a time value set to be the current highlight time t. It is a method of highlight recording processing of VSI that is performed by the highlight recording processing program of a series of processing that goes back to the recording stop mode when t is greater than or equal to Z by checking whether it is larger than z.

Hereinafter, more specific features of the present invention will be understood by describing the same in detail with the accompanying drawings.

Fig. 5 shows the main part circuit block of the VSI's highlight recording processing system according to the present invention.

Here, the KBPS decoder 11, which is connected to the tuner and IFA unit 8 of the VSI system and detects KBPS data, and the audio amplification unit 84 of the tuner and IFA unit 8, is provided. The signal detection unit 13 which detects the audio signal level being connected and received, compares the contents set in the reserved recording with the current reception contents provided to the KPS decoder 11 and recognizes whether the data match, and on the other hand, the audio system Signal is detected from the signal detection unit of the microcomputer 12 and the control signal is executed from the microcomputer 12 at the start of the reservation recording. It consists of the structure containing the signal detection part 13 etc. which detect a level and provide it to the microcomputer 12. As shown in FIG.

The tuner and IFF section 8 includes a SIF detector 82 for detecting a sound signal at a channel frequency signal tuned from the tuner section 81, and a sound for demodulating the sound signal following the output thereof. The demodulator 83 includes a demodulator 83, and a signal amplification unit 84 or the like which is connected to the output thereof to amplify the signal.

The microcomputer 12 is connected to a servo controller 14 for controlling the drive system of the deck 15 and a deck 15 for performing tape playback / recording operations.

On the other hand, the microcomputer 12 or the like is equipped with a highlight recording processing program 100 as shown in FIG.

In this case, it is checked whether the system is in the scheduled recording mode (step 101). If it is a weak recording, it is checked whether it is a highlight recording (step 102). If the checked result is a highlight recording, the system is placed in the pause mode. (Step 103).

Then, the microcomputer 12 detects the signal level from the audio signal detection unit 13 (step 104), and checks whether the detected audio detection level is a random value x and the time is greater than y (step 105). When this condition is satisfied, the recording mode is performed (step 106).

Thereafter, it is checked whether the current highlight time t is greater than or equal to z (step 107), and when t is greater than or equal to Z, a series of processes are performed to go back to the recording stop mode.

In the present invention, as shown in FIG. 5, the KBPS signal is multiplexed and assigned to the video signal received through the tuner and the F8 in such a system. It contains a byte synchronizer, a data header, and a data block.

In addition, the contents included in KBPS data include current time data, program start time for one week to four weeks, length, title, day map, applicable code, station name, code name currently being broadcast, etc. Including stock price information, travel information (train time, airplane time, express bus time), weather information, sports information, etc., the KBPS decoder 11 decodes such information and decodes the information necessary for the system into a microcomputer processor. (12) will be provided.

Therefore, the system microcomputer 12 retrieves the contents set by the user from the reserved recording and periodically compares the KBPS data currently received through the KBPS decoder 11.

At this time, when the microcomputer 12 matches the user reservation data (sports program) and the data currently received, the system is placed in the recording stop mode and the control signal is sent to the signal detector 13 so that the signal detector 13 receives audio. The sound output level currently received through the signal amplifier 84 of the reception system is detected.

The signal detector 13 detects such a level and provides the detected state to the microcomputer 12 because the loudness of the sound output is caused by the crowd of the crowd in a relatively dramatic portion during the sporting event.

When the signal level provided from the signal detector 13 is greater than or equal to a certain amount and it continues for a certain time, the microcomputer 12 considers this as a highlight signal and proceeds with recording.

Therefore, since the system can record only a specific highlight signal during the sports relay, unnecessary recording can be eliminated without the necessity to record the entire sporting event, and only the highlight scene can be selectively reproduced and viewed during playback.

On the other hand, the above operation is performed by the microcomputer 12 together with the highlight recording processing program 100 as shown in FIG. 6, where the system checks whether the system is in the reserved recording mode, and in the case of weak recording, checks whether the recording is highlighted. If the checked result is the highlight recording, the system is placed in the pause recording mode (steps 101 to 103).

Thereafter, the microcomputer 12 detects the signal level from the audio signal detection unit 13, and checks whether the detected audio detection level is a random value x and the time is greater than y. (Steps 104 to 106).

After that, it is checked whether the current highlight time t is greater than or equal to z, and when t is greater than or equal to Z, it goes back to the recording stop mode and continues recording only the highlight portion (step 107).

If the recording is not in the above-described highlight recording, the general-purpose reservation recording is performed (step 108). If the audio level is not satisfied with the predetermined condition, it is checked whether the reservation time is over (step 109). When the reservation time ends, reservation recording ends (step 110).

The present invention is capable of pre-recording by selecting only a specific highlight portion in the process of pre-recording the sports program of the VSI system having the KB PS reception function, so that the entire recording of the sports program is not necessary. Unnecessary tape waste can be avoided, and highlights can be viewed only during playback, so you can expect convenient use.
