How to deal with tape duplication prevention alarms on Vishial systems

The present invention relates to a tape duplication preventing means in which a duplication preventing signal is recorded in a Vishal system having an OSD function. This is particularly effective when a copy protection signal is placed on a tape of a vial system and a user performs a duplicating operation If you do, you will be informed of the appropriate warning message.

A typical Vishial system provides a variety of interactive menu selection methods through a television screen to provide a variety of OSD menu screens for scheduled recording / playback / clock adjustment / channel presetting and the like.

For example, a system circuit that performs this function has shown this as shown in FIG.

Here, the control unit 1 includes a system microcomputer for controlling and managing the vial system, a deck unit 4 driven under the control of the control unit 1, cam data installed in the deck unit 4, A sensor section 7 for providing input to the microcomputer, an OSD section 2 for providing appropriate display data to the screen, a synchronization generating section 3 for providing a synchronization signal to the OSD section 2, A signal processing unit 5 for processing a video signal and providing the video signal to the system, and an output of the signal processing unit 5 and an output of the OSD unit 3 And a totalizer that is added to the system and provided to the system.

In this system, when the user presses the output selection key on the OSD menu screen for the user to perform the scheduled recording through the command input unit 6, the microcomputer 1 of the control unit 1 recognizes it and is stored in the system memory The OSD screen data is called up.

Then, predetermined picture data is formed through the OSD unit 2, and the video signal output from the signal processing unit 5 is added to the sum of the video signal and the reproduced video information to the TV receiver side.

For example, in this system, a mode for performing interactive interactive reservation recording is as follows.

In the above-described interactive menu selection method, the user can press the reservation recording / cancel selection button in Table 1, perform channel selection in Table 2, and schedule recording in the order of date, time, etc. in Table 3 .

Means for generating a warning message through the OSD screen in order to prevent the prevention of recording due to user carelessness in the system using the above-mentioned conventional means is disclosed in Korean Patent Publication No. 1212, Publication No. 94 -4564.

Here, if the user presses the recording command key through the command input unit 6 after loading a blank tape in the system, the system checks whether the recording command is a recording command by checking the recording command key, and then checks whether the recording tape is recordable.

If the recordable tape is a recordable tape, a predetermined warning message related to recording confirmation is output to the television receiver through the OSD unit 2. After a predetermined time elapses, a check is made to see if there is an input of a record confirmation command key, The recording operation is normally performed, and if there is a recording confirmation command, it is checked whether there is an input of another command key to perform the function of the corresponding selection key.

However, according to the related art, the user inserts a tape that should not be recorded at the time of tape recording into the system deck and outputs a message screen asking for confirmation in advance without proceeding to the direct recording, thereby reducing the side effect at the time of recording However, the present invention does not provide various warning functions such as replicating a tape on which other copy protection signals are recorded, and the like.

For example, Vieques tape, which is on the market or rented or sold at a video rental store, contains copy protection signals.

However, it is often the case that an ordinary user replicates such a copy protection tape by considering it as a normal tape, and the content of the copied program in this way is remarkably deteriorated in image quality, and it becomes impossible to view.

In such a case, the user often thinks that the set is defective and requests the AS, and the system provider loses the reliability of the product due to the above-mentioned misunderstanding, or it is difficult to avoid troublesome problems according to the AS.

In addition, the copy protection means for recording the copy protection signal on a tape generates a normal signal at the time of normal reproduction by using the age characteristics of the video signal, but when copying the current vial system and another vial system via a line , The video signal being reproduced in the Vishial system having the original changes in the level of the DC signal in the age of the video signal, so that the normal reproduction signal can not be obtained in the Vishal system.

In this way, conventionally, when a user copies a VISIR system containing an original tape to another VISIAL system or the like, it is mistaken as a system error as described above, resulting in a lot of problems.

It is an object of the present invention to provide a system and method for copying a tape containing a copy protection signal so as to solve the above problems by displaying a predetermined warning message through the OSD screen, Such as malfunctions, can be removed in advance.

The present invention particularly relates to a method of reproducing a video signal in a system so as to realize the object of the above example and checking whether the age level of the reproduced signal is in a normal state or not, And outputting a message to the video screen. The method of the present invention is characterized by a tape duplication prevention warning processing method of a Vishal system.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

That is, FIG. 1 shows an excerpt of a system circuit block related to the present invention.

In this case, an aging section 10 for receiving a regenerative signal of the Vishal system and generating a DC voltage for aging control, and an aging section 10 connected to the output of the aging section 10 to supply the microcomputer 12 with an analog DC level And is connected to an AD converter 11 which converts the digital data into digital data.

A microcomputer 12 for controlling the system as a whole is connected to the output of the AD converter 11. An OSD unit 14 for generating OSD screen data is connected to an output port of the microcomputer 12 have.

A video buffer 13 for processing a video signal is connected to another output path of the agile section 10 and a reproduced video signal generated through the video buffer 13 is supplied to the output section of the OSD section 14 And outputs the summed output signal.

On the other hand, the system microcomputer 12 is provided with a copy protection warning processing program 100 as shown in FIG.

The copy protection warning processing program 100 enters a playback board after tape charging is completed with the system being powered on to reproduce a video signal (step 101), and checks whether the age level of the reproduced signal is normal (Step 102).

If there is an abnormality in the age level in the above case, a copy prevention OSID warning message is called up via the OSD 14 (step 103), and this is output to the video screen (step 104).

In the present invention, when a user connects another vial set to a vial set with a line or the like, and starts to copy a desired original tape for copying to the vial set side, The video signal is supplied to the video buffer 13 while providing an analog output to the AD converter 11 in DC level aging.

When the analog converter 11 provides the analog signal of the agile level to the microcomputer 12 as digital data, the microcomputer 12 proceeds the copying according to the input age value, A copy protection warning message is output.

The OSD copy protection screen at this time can be configured as follows, for example.

warning ! If you continue copying, you will be punished under copyright law, and duplicate video signals can not be played normally.

Quot; can be displayed through the TV receiver.

The user can confirm that the currently used tape can not be copied by viewing such a message, and thus can easily support the user's tape usage environment.

4 is performed by the copy prevention warning processing program 100 shown in FIG. 4. This is because when the system is powered on, after the tape loading is completed, the system enters the playback board to play back the video signal, It is checked whether the age level of the reproduced signal is in a normal state (steps 101 and 102).

If there is an abnormality in the aging level in the above, the copy protection OS warning message is output through the OSD unit 14 and is output to the video screen. In a normal case, a normal video signal is provided to the system (Steps 103 and 104).

In the present invention, when copying a tape in which a copy protection signal is inserted at the time of copying a tape using a vial system, it is shown to the user that the current tape is a tape that can not be copied, The convenience of the apparatus can be improved.
