Description

How to record Bismark in TV mode still mode

The present invention relates to a method for additionally recording a bismark in the still mode of the TVCR, in particular, when the user presses the bismark additional function key on the remote control, the user automatically switches to the still mode, and when the user additionally records the bismart in this state, If you input the title and brief information of the program corresponding to the unique number of the vismark while specifying the unique ID number on the OSD screen, the time required to add the vismark to the playback / recording tape by canceling the still mode is caused. Method for additionally recording on still mode of TVCR, which reduces the positional error so that the user can add the bismark accurately to the desired position.

In general, a TVCR is an integrated product of a television and a VCR. The TVCR is powered by a single power supply and is controlled by a system control (SYSCON) that controls the VCR and a timer that controls the entire TVCR system. Each component is operated, and is a device used for recording and reproducing television broadcast signals, recording and reproducing other recording tapes, broadcasting recording of other channels not being watched, reserved recording, and absent recording.

Such a video record reproduction processing system such as a TVCR or a general VCR employs a video index search system (VISS) function for searching a program desired by a user at high speed.

In other words, in the TVCR or VCR, the Vis function is a search function that allows the user to find and watch a desired position when the user wants to play the video tape and writes an index pulse (Bismark) during recording at a desired position of the normal recording tape. do.

The method writes a control signal of a different type from the normal pulse on the control track of the recording tape at the time of recording, and records a bismark at the beginning of each recording when several programs are recorded on one video tape. do.

By doing this, the motor of the TVCR or the VCR is driven at a high speed by the user's operation at the time of reproducing to find and reproduce the place where the bismark is present.

However, when searching for a desired program among a plurality of programs using a conventional vis function, a large amount of time is consumed because the indexes inserted in the front end of the plurality of programs must be searched in sequence, and each program recorded on the magnetic tape is also used. In order to search the contents of the program, there is a problem that all the search must be performed by sequentially scanning the indexes inserted in the front end of the program.

In consideration of these problems, Korean Patent Publication No. 1105 (Publication No. 93-17017) stores a prime screen of a place where a bis signal is carried on an image recording floppy disk and outputs it to a monitor through an interface with a microcomputer. It allows the user to know how many times the service number is desired.

However, according to the related art, there is a problem in that one frame screen of the place where the VIS signal is loaded is cumbersome to be recorded on the image recording floppy disk.

Also, since you cannot add a bismart when playing a videotape or playback tape that has already been recorded, you cannot use the vis function by visibly marking a scene you want to watch when playing a videotape. In order to search for a specific part of the recorded videotape, there was a problem in that it was cumbersome to use the fast-forwarding function such as FF or CUE mode.

In addition, since the user must input the service number and program title and brief information through the OSD screen while the user presses the Vismark additional recording key on the remote control, the user actually presses the Bismark additional recording key and records the actual recording. Since a predetermined time has elapsed until this point, there is a problem that the position where the Bismark is actually recorded is slightly out of the desired position to be recorded.

The present invention is to solve the above problems, by adding the bismart to the recording / reproducing tape in the still mode of the TVCR, the position caused by the time required to add the bismark on the recording / reproducing tape It is an object of the present invention to provide an additional recording method for bismarks in the still mode of a TVCR, which can reduce the error so that the user can add the vismarks exactly where desired.

As a technical idea for achieving the object of the present invention, the process of converting to the still mode by checking this when the bismark additional function key is input by the remote control during playback of the video tape, and when the still mode switching process is completed Displaying a message asking for confirmation of additional recording on the OSD screen; checking whether the tape inserted in the deck portion is a tape for rusting, if a bismark additional recording is selected on the OSD screen; If it is confirmed that the tape is a recycled tape and not a recycled tape, displaying a warning message on the OSD screen to confirm whether to add the bismark again. If it is determined that the tape is a recording tape, and the above judgment result, enter the service identification number The process of displaying the OSD screen, the process of adding a predetermined service identification number to the beginning of the additional recording Bismark when the service identification number is input by the remote control, and canceling the still mode when the service recording process is completed An invention is presented that performs the process of doing so.

Referring to FIG. 1, the TVCR according to the present invention includes a high frequency amplifier for amplifying a high frequency signal, which is a composite video signal received from an antenna 10, a local oscillator for supplying a signal for frequency conversion, and amplification from the high frequency amplifier. And a tuner unit 11 configured to receive a local oscillation frequency from the local input unit and a local oscillation unit and convert the intermediate oscillation frequency into an intermediate frequency so as to select a high frequency signal of a desired channel and convert it into an intermediate frequency, and the tuner unit 11. While amplifying, processing and outputting an intermediate frequency signal, which is a composite video signal, is output from the VCR Y / C IC 14 to be described later, the playback is performed from the VCR Y / C IC 14. A TV image processing IC 13 for receiving a composite video signal and outputting the composite video signal to the CRT unit 12, and a CRT unit 12 for outputting a composite video signal output from the TV image processing IC 13; .

In addition, the TVCR according to the present invention receives the composite video signal from the TV image processing IC 13, modulates the luminance signal into the FM low carrier, and converts the color signal into the low pass, while connecting to the VCR Y / C IC 14. A VCR Y / C IC 14 for applying a playback composite video signal generated by demodulating the modulated luminance signal and the color signal output from the head amplifier IC 15 to the original signal to the TV image processing IC 13; After amplifying the luminance signal and the color signal modulated from the VCR Y / C IC 14 and recording them on the video head of the deck unit 16, the signals recorded on the video head are read. A head amplifier IC 15 for amplifying and demodulating is provided.

In addition, it is connected to the remote control unit 18 and the tuner unit 11 and the TV image processing IC 13 to wirelessly apply various user's control commands to the timer 17. The control signal is applied to the TV image processing IC 13 according to the signal and the sheath 19 is controlled, and the playback position according to the table of contents when the recording tape is played is recorded in the recording tape and the recording time data stored in the recording tape. And a timer 17 for driving the OSD processing unit 20 and the VCR Y / C IC 14 to detect the synchronization signal C-SYNC. A synchronous detection unit 21 for receiving the synchronous signal from the synchronous detection unit 21 and controlling the VCR Y / C IC 14, and storing and outputting the same under the control of the timer 17. A memory unit 22 consisting of an EEPROM and a safety unit located at a lower end of a video tape. It is provided with a recording protection switch section 23 which sends a predetermined signal to the sheath 19 so as not to be recorded when the presence or absence of a tap is determined.

The operation of the present invention configured as described above with reference to the flow chart of Figure 2 as follows.

When a user uses the remote control to play a video clip on a TVCR or a regular VCR while watching a videotape and finds a picture that he wants to watch repeatedly, he or she must record a bis mark on that part.

To this end, a bismark additional function key is provided on the key input unit of the remote controller 18. When a user presses it to record a bismark at a desired position of the video tape being played, the corresponding control code is converted into a predetermined optical signal. After being sent out, it is applied to the timer 17 via a remote control receiver (not shown) of the TVCR or VCR.

When the non-smark additional input signal is applied to the timer 17, the timer 17 checks this and then sends a control signal to the scissor 19. Accordingly, the sciscon 19 sends a control signal to the deck unit. The current regeneration mode is switched to the still mode (Still mode) in which the capstan motor is stopped (S100 and S101).

Subsequently, the timer 17 controls the OSD processing unit 20 to display a message for confirming the addition of a bismark recording record such as "Do you want to add a bismark? Yes / No" to the CRT unit 12 (S102). .

At this time, when the user selects "Yes" by operating the remote controller 18, the timer 17 checks this and then sends a control signal to the sheath cone 19, whereby the sheath cone 19 is currently in the deck portion 16 ) To determine whether the tape for the rust material is applied (S103, S104).

This determination process is made in the sheath cone (19). That is, when the video tape is loaded into the deck unit 16 under the control of the sheath cone 19, the recording protection switch unit 23 determines whether there is a safety tap located at the lower end of the tape to generate an active high or low signal. It is sent to the sheath cone (19).

In general, the sheath cone 19 is recognized as a tape for rust ash having a safety tap upon receiving an active high signal, and is recognized as a playback tape without a safety tab when receiving a low signal to prevent recording.

Anyway, if it is determined through the above judgment process that the tape is not a recording tape but a playback tape, the sheath cone 19 sends a control signal to the timer 17 again, and the OSD processing unit 20 is controlled by the timer 17 accordingly. Through the CRT unit 12, a message such as "This is a playback tape. Do you want to add a bismark? Yes / No" is displayed (S105).

At this time, when the user selects "Yes" by operating the remote controller 18, the sheath cone 19 checks this and then softly recognizes the playback tape currently loaded in the deck unit 16 as the rust tape. The recording / reproducing tape determination signal is set to active high in the wear program (S106 and S107).

On the other hand, if the determination result of the ciscon (19), if it is determined that the tape for rust ashes sends a control signal to the timer 17 again to control the OSD processing unit 20, accordingly, the OSD unique number is input to the OSD screen OSD The screen is displayed (S108).

At this time, when the user inputs the service identification number by operating the remote controller 18, the timer 17 checks this and then controls the OSD processing unit 20 again. Menus for inputting information are displayed (S109, S110).

At this time, when the user operates the remote controller 18 to input the title and the brief information of the program into the menu, the timer 17 checks this and then sends a control signal to the memory unit 22 to input the title and the brief information of the program. Information is stored in the memory unit 22 (S111, S112).

When all of the above processes are completed, the sheath cone 19 recognizes the playback tape currently loaded in the deck unit 16 as the rust tape and starts recording Bismark further on the desired position control track of the video tape. The unique number input by the user is added to the portion to be recorded (S113).

When all of the above bismark additional recording processes are completed, the sheath cone 19 sends a control signal to the deck unit 16 again to release the steel mode by driving the capstan motor.

Therefore, the user can easily and accurately search for a desired broadcast program by memorizing the service unique number when finding the corresponding position of the video tape to be watched again.

On the other hand, if the user wants to know the program title and brief information of the desired service specific number, press the service unique number identification key of the remote control 18, and then press the desired service unique number, at this time, the control signal is converted to the remote control receiver After receiving the light, it is converted into a predetermined signal and applied to the timer 17.

At this time, the timer 17 receiving the predetermined signal controls the OSD processing unit 20 to display the title and the brief information of the corresponding program read from the memory unit 22.

Therefore, the user can know the program information by looking at the title and brief information of the program.

As can be seen from the above description, in the present invention, when the play mode of the videotape is executed, when the vismark additional function key is inputted by the remote controller, the vismark additional recording is performed after switching to the still mode under the control of the scissor 19. A message asking for confirmation is displayed on the OSD screen. At this time, when the user selects the bismark recording record on the OSD screen, the system console 19 checks whether the tape loaded in the deck unit 16 is a rust tape. If it is determined that the recording tape is not a rust tape, the play tape is forcibly recognized as a rust tape, and if it is determined that the tape is rust tape, a service ID input OSD screen is displayed. When a service identification number is input by the user, a predetermined service identification number is additionally recorded at the beginning of the additional recording marks. When the recording process is completed, the still mode is released again under the control of the scissor to reduce the positional error caused by the time required for additional recording of the vismark on the recording / recording tape. You can add a bismark.

In addition, when the user wants to see the desired program again among various programs recorded on the videotape, the user can find the corresponding location conveniently by checking the service unique number.

In addition, the user inputs the title and brief information of the program corresponding to the unique number of the vismark on the OSD screen and stores it in the memory unit 22. If the user knows the unique number of the service, the user operates the remote controller 18 to operate the corresponding service. You can also check the contents of the program by displaying brief information of the program recorded with the unique number on the OSD screen.
