Description

Method of processing control of recording scene of VSI system

The present invention relates to a recording scene sorting control processing means for recording the index information or address information in a plurality of programs recorded on a tape and performing screen searching using the same. When dubbing, etc., a selective index code is assigned to the main scene of a predetermined program, and the selected scene can be selected and viewed through the OS screen at the time of playback to facilitate the search for a specific scene in the program. will be.

The VSI system is an electronic device that is commonly used with a TV receiver, and a general circuit block diagram of the VSI system is illustrated in FIG. 1.

Here, a tuner 34 for receiving a regular broadcast signal from an antenna 33 of a VSI system and performing channel tuning, and a phase for controlling a phase locked loop (PLL) of the tuning signal provided from the tuner 34. The lock loop circuit 35, the microcomputer 32 which controls a BC system, etc. are included.

In addition, the system includes an OSD circuit 41 for generating a screen interactive OSD screen, a VSI system memory 42, a key input unit 31 for various key operations together with a remote control transmitter, and a recording / playback deck. Deck 36 which operates, servo circuit 37 which controls the drive motor etc. of the deck 36 side, RF converter 38, the video block 39 of video signal processing, TV receiver 40 It also consists of a configuration that includes.

When recording a TV broadcast program or the like on a VSA tape in the conventional VSA system, when the recording key is pressed from the key input unit 31, the deck 36 is driven by the control of the servo circuit 37 to proceed with recording. In this process, the so-called Video Index Search System (VISS) function was performed by recording an index signal for ease of search after recording of a program to a control track of a tape through a control head.

The vis function makes it possible to easily find the tape recording contents of a certain part by recording the index information using the change of the duty on the tape to the control pulse used for the phase control of the capstan.

At this time, the use of the vis function was performed by inserting or deleting an index signal during tape recording, or searching for an index part by operating key buttons such as index +, index-, and index scan on the keypad of the remote controller transmitter.

Meanwhile, another tape program management technology other than the above-described service function is implemented by applying a bath address to a tape program, and the VHS type bath address data format of the technology is shown in FIG. 2. .

In addition, a means for cataloging a bath address using the bath address data format as described above is known from Korean Patent Publication No. 1239 (Publication No. 92-16026), which is shown in FIGS. 3 and 4.

Here, the main controller 61, which is connected to the bath system 64, performs the heading specification and the bath address cataloging control of the bath address, and the control operation of the main controller 61 so that the characters can be combined with the composite video signal. A character generator 62 for synthesizing characters to a composite video signal in a designated format, and a RAM 63 for storing the listed data so that the data can be displayed through the character generator 62 during tape record retrieval. .

In such a conventional system, as shown in FIG. 4, if there is a tape insertion in the system, it is checked whether there is an entry of the bath address listing key, and if there is an entry of this key, a title OSD display and a tape rewinding operation are performed. Check whether the winding title OSD display and tape run are finished and if there is a bath address detection at the end of tape.

If there is a bath address detection, it detects the bath address, displays the OSD display real-time count, goes back to the tape fast forward mode, and checks whether there is a title change selection at the end of the tape. To do the job.

However, in such a conventional system, the program search technology using the service function is able to discriminate whether a program is started or not on a tape, so that the user does not show a technique of organizing and finding specific scene data in the program content as needed. The latter bath technique can improve the program search function as a means of cataloging the bath address, but complicates the system configuration for this, and reads each bath address assigned to the tape, stores them in memory, and recombines them. It was difficult to exclude the inconvenience of operating the system due to the complexity of the operation means.

An object of the present invention is to provide an index code to a tape control track and a system memory in order for an impressive scene of a specific program to be performed when a user of a VSI system performs a VSI vs. VDial dubbing operation. By recording and replaying each scene, users can directly select and view the scene through the OS screen, so that such a system can facilitate organizational management and search for a specific scene.

The present invention specifically implements the object of the above example, the system checks whether the beginning of the recorded program during the dubbing operation of Vsial vs. Vsial checks whether there is a program start key input of the user, and if there is a start key input, the start index of the recorded program The code pulse is recorded on the tape and the start data is generated and registered in the memory.If there is a scene key input, the index code pulse is recorded on the tape at every scene key input, and the sequence data is generated and registered in the memory in order. And recording the end index code pulse of the recording program on the tape and registering the end data in the memory when the recording is finished, and stopping the recording when the end sensor is input. Recording scene screening control program A recording scene selection control method of a V-sialic system line is characterized.

That is, FIG. 5 shows a system circuit block related to the recording scene sorting control processing method of the VSI system according to the present invention.

Here, the key input unit 11 for inputting various command keys, the microcomputer 12 which performs system control according to the control command of the key input unit 11, and the recording / playback and various decks under the control of the microcomputer 12 A deck 13 for performing an operation, a control pulse generator 14 for recording control pulses on a tape control track during tape drive of the deck 13, and a tape end to detect the end of the tape. It consists of a configuration including the end sensor unit 15 and the like to provide.

In addition, the system is provided with a recording scene sorting control processing program 100 as shown in FIG.

In this case, it is checked whether the system is in the recording mode (step 101). If the system is in the recording mode, the recording operation is performed (step 102). Then, it is checked whether the user has a program start key input (step 103).

If there is a start key input as described above, the microcomputer 12 generates a program start index code pulse through the control pulse generator 14 and records it in the control track of the tape (step 104), and again this start index code. Is stored in the program scene table on the memory side (step 105).

When the user wants to register a particular impressive scene while recording, the scene key is pressed and the microcomputer 12 checks it (step 106). While recording to tape (step 107), these data are stored in a memory (step 108).

After that, the system checks whether or not the recording ends according to the condition that the recording is completed and the synchronous signal does not occur for a certain time (step 109). If the recording ends, the system records the recording end index code on the control track (step 109). 110) The program end data is registered in the memory (step 111).

When the tape continues to reach the end of the tape, a series of processes are performed to check whether there is an end sensor input (step 112), and to stop recording when there is an end sensor input (step 113).

According to the present invention, when a user performs a VSI vs. VDial dubbing operation in a VSI system, a user may assign an index code to an impressive scene of a program and select and view it through an OS screen.

At this time, the scene index code is assigned by the sequence number code selected through the key input unit 11 of FIG. 5 and the end of the program whenever the specific scene is recognized through the program start position and the screen of the recorded program. Each position is recorded on the tape through the control pulse generator 14 and the position is registered in the program scene table of the system memory.

The virtual program scene table at this time may be assigned as shown in Table 1 below.

TABLE 1

Therefore, in the recording tape, the index code is recorded on the tape and registered in the memory in accordance with the scene sequence that the user presses through the key input unit 11 whenever necessary.

When you play this recorded program, whenever you need the scenes

It can be called out and enjoyed.

At this time, it can be called through the screen interactive OSD screen as shown in Tables 2 and 3 below, or can be directly called by using a tenkey assigned to the remote control transmitter.

TABLE 2

If you press 5 in Table 2,

TABLE 3

When the screen as described above appears and the user presses the required number, the deck unit 13 is driven to go directly to a predetermined position.

Meanwhile, the above operation is performed together with the recording scene selection control processing program 100 of FIG. 6, which checks whether the system is in the recording mode, and performs the recording operation in the recording mode. It is checked whether there is an input (steps 101 to 103).

If there is a start key input in the above, the microcomputer 12 generates a program start index code pulse through the control pulse generator 14 and writes it to the control track of the tape, and then records this start index code on the memory side. The program is stored in the program scene table (step 104, 105).

When the user wants to register a particular impressive scene during recording, the scene key is pressed and the microcomputer 12 checks it, and if there is a scene key input, the index code is recorded on the tape according to the scene key pressing procedure. On the other hand, these data are stored in the memory (steps 106 to 108).

After that, the system checks whether the recording ends according to the condition that the recording is completed and the synchronous signal does not occur for a certain time. If the recording ends, the system records the recording end index code on the control track and records the program end data. It registers in memory (steps 109-111).

When the tape continues to reach the end of the tape, it is checked whether there is an end sensor input, and when there is an end sensor input, recording is stopped (steps 112 and 113).

In the present invention, an impressive scene, etc. among predetermined program contents reproduced through a tape in a VSI system can be selected at the time of recording by user selection, and the scene can be easily viewed selectively during playback. There are beneficial features that can be implemented in various ways.
