Abstract

The present invention relates to a recording and reproducing method for restricting viewing of adult protape or the like in a VSI system having an OSD function. In the related art, a bar code sticker is attached to a video cassette margin in such a system, and reservation recording information and Although adult identification information is read and the corresponding system restriction processing is performed, such a system has a contradiction in that the juvenile viewing function itself is lost when the bar code sticker itself with adult classification information is intentionally damaged.

The present invention is to set the duty pulse of the control signal recorded on the tape in the reverse recording mode to record a certain ratio (adult) when recording the adult tape to improve the conventional problem of the tape In reverse play, the microcomputer 3 first recognizes whether the tape inserted in the deck 6 is adult by the duty ratio of the control pulse, and secondly, the password set in advance through the screen interactive OSD screen. Since the correct reverse playback can only be performed by inputting, it is possible to enforce the parental control of the adult tapes, thereby providing a reliable function for protecting the minor emotions.

Description

Selective Playback and Recording Method of Adult Tape of VSI System

The present invention relates to a recording and reproducing method for restricting viewing of an adult pro tape or the like in a VSI system having an OSD function, in particular a control recorded on the tape in a reverse recording mode during recording of an adult tape in the system. If you set the duty pulse of the signal to a certain ratio (adult) and record it, the microcomputer first recognizes whether the tape inserted into the deck is adult by the control pulse's duty ratio during reverse play of the tape. Secondly, it is necessary to input the preset password through the screen interactive OS screen to perform the correct reverse playback operation.

In general, a VSI system is a device which receives various video / audio sources and records them on a cassette tape or reproduces a recorded pro. A typical form thereof is shown in a system circuit block diagram as shown in FIG.

In this case, the tuner unit 2 which receives the regular broadcast signal from the antenna 1 of the VSI system and performs channel tuning, the microcomputer 3 that controls the VSI system, and the OSD unit which generates the OSD screen (4), a VSI system memory 5, a deck 6 for recording / playback deck operation, a key input unit 7, an RF modulator 8, and a video processing unit 9 for processing video signals. ), An external TV receiver 10, a remote controller transmitter 11, and a remote controller receiver 12.

In the above system, when the function key is pressed through the remote control transmitter 11 or the like, the microcomputer 3 generates the OSD menu screen through the OSD 4, and the screen is interactive through the TV receiver 10. It was to perform a function setting operation.

On the other hand, conventionally, a variety of methods are known to prevent minors from watching the adult program in the above system, one of which is known in Korean Patent Publication No. 3669 (Patent No. 94-5846).

In this case, a bar code sticker that codes the reservation recording information is attached to one side of the video cassette tape to complete the setting of the reservation recording program with the insertion of the cassette tape, while attaching a bar code sticker for children / adults. It was designed to prevent children from seeing adult tapes.

In other words, in this technology, when a cassette tape with a bar code sticker marked with bar code information is inserted into the system, the bar code sensor installed on the system deck reads the bar code sticker contents. In case of timer reservation data, it saves it in memory and displays reservation contents in OSD characters. If read barcode data is children / adult classification data, it is performing the lock function and if the adult and barcode cannot be recognized, the playback operation is not performed. It was made as a means of performing a process that does not.

In addition, another conventional technique is known in Korea Patent Publication No. 3769, Publication No. 94-9466, which displays a certain color on the tape label, and in the form of controlling the stop key by distinguishing the color of the label in the system It is done.

However, the former technology of such a system has a problem that a minor user cannot perform this function at all if the barcode sticker is separated from the cassette tape margin or the barcode information is simply damaged.

In addition, in the latter case, additional hardware configuration is required to include at least a ten-key switch unit for registering and inputting a separate password for the underage viewing function. It has been the cause of the price increase.

As described above, in the conventional prior arts, the above-described encryption means and the like do not have a flexible use environment, so they are practically lacking in practical use.

An object of the present invention is to set the duty pulse of a control signal recorded on the tape to a certain ratio (adult) in the recording of adult pro tapes in the system, so that the tape is used by the microcomputer for the reverse playback of the tape. The present invention provides a method for reproducing and recording an adult tape of VSI System that can perform a replay operation only after a recognition of the recognition is performed first and a second password is input through the OS screen.

In particular, the present invention is to determine whether the ratio of the duty pulse generated from the control pulse generating unit in the normal mode and the adult mode after executing the reverse playback mode by the microcomputer to implement the object of the above example, and then the adult ratio. The adult playback mode processing step of executing the reverse playback mode by confirming the password inputted to the OSD unit, and the adult duty pulse from the control pulse generator under the control of the microcomputer when the recording mode is executed to the control track of the tape. It is characterized in that it comprises an adult reverse recording processing step of executing the reverse recording mode through the step of sequentially setting the password after recording.

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

2 is a flowchart illustrating a method for selectively reproducing and recording an adult VSI tape according to the present invention.

First, in the VSI system including the microcomputer 3, the OS unit 4, the deck 6, the key input unit 7, the RF modulator 8, the video processing unit 9, and the like, the microcomputer ( 3), the ratio of duty pulses generated from the control pulse generator under the control of the microcomputer 3 when the reverse play mode is executed is changed into the normal mode (usually 50:50) and the adult mode (for example, 75:25). After determining the adult ratio, and after the adult playback mode processing step of executing the reverse playback mode by checking the password input to the OS unit 4, and the adult duty pulse from the control pulse generator when the recording mode is executed It includes the adult reverse recording processing step of executing the reverse recording mode through the step of setting the password in sequence after recording on the control track of the tape. First, look at the adult reverse playback mode processing step Below.

That is, the microcomputer 3 first determines whether an input signal is applied to the playback key by the user (step 10).

At this time, if an input signal is applied to the play key, the reverse play mode is executed (step 20). If the input signal is not input, it is determined whether an input signal is applied to the record key again.

Further, when the reverse play mode is executed sequentially, the duty ratio of the control pulses is detected from the control track of the tape (step 30).

Subsequently, the duty ratio of the control pulse detected from the control track is compared and determined with the adult duty ratio set value preset in the microcomputer (step 40).

At this time, if the duty ratio of the detected control pulse is an adult duty ratio (for example, 75:25), the microcomputer 3 recognizes this and draws out password input OSD data from the internal memory and provides it to the OS4. The OS unit 4 provides the video output to the TV receiver 10 through the video processor 9, and accordingly, a password input screen is output to the TV receiver 10 (step 50). .

If the adult duty ratio is not the same, the normal playback routine is called (CALL) (step 51), and it is then determined whether or not the user's password matches the password set when the user inputs the password on the password input screen (step 60).

At this time, if the input password matches the set password, the reverse playback mode is executed (step 70).

If the input password is inconsistent with the set password, the tape stops running, and then it is determined whether or not the execution of the reverse play mode is completed sequentially (step 80).

Further, when the execution of the reverse playback mode is sequentially completed, the tape is stopped (step 90).

At this time, if the reverse regeneration mode continues to be executed, the process returns to step 70 again.

On the other hand, the adult reverse recording process first determines whether an input signal is applied to the recording key by the user (step 100).

At this time, if an input signal is applied to the recording key, the reverse recording mode is executed (step 200). If not, step 100 is performed again.

In addition, when the reverse recording mode is executed sequentially, the control pulse having the adult duty ratio is recorded on the control track of the tape (step 300).

At this time, when a control pulse having an adult duty ratio is input to the control track of the recording tape, the microcomputer 3 recognizes this and draws out the password input OSD data from the internal memory and provides it to the OSD 4. The SD unit 4 provides a video output to the TV receiver 10 through the video processor 9, and thus a password setting screen is output to the TV receiver 10 (step 400).

Subsequently, the user sets a password by using the remote control transmitter 11, etc. At this time, the microcomputer 3 determines whether the password setting is terminated by the user on the password setting screen displayed on the TV receiver 10. (Step 500).

First, when the password setting is completed, the password setting screen of the OS unit 4 is turned off (step 600), and when it is not completed, the process returns to step 400 again.

After determining whether or not the reverse recording is finished (step 700), if the reverse recording is finished, the reverse recording is stopped (step 800). If not, the process returns to step 200 again.

For reference, the contents of the password input screen provided to the TV receiver 10 by the processing of the OS unit 4 may be configured as follows.

If the user inputs the correct password using the tenkey of the remote control transmitter 11 through the screen as described above, the screen disappears and the microcomputer 3 drives the servo and the deck to perform the playback operation.

On the other hand, the screen as described above disappears even if you wait for a certain period of time, and the minor who does not know the password will not be able to watch the adult pro because the playback operation using the system is not possible.

The present invention is to set the duty pulse of the control signal recorded on the tape in the reverse recording mode at the time of recording the adult tape to a certain ratio (adult) to record the micro computer (3) in reverse playback of the tape First recognizes whether the tape inserted in the deck (6) is adult only by the duty ratio of the control pulse, and then enters the preset password through the screen interactive OSD screen. By doing so, it is possible to enforce the restriction on the viewing of minors in adult tapes, thereby providing a reliable function for protecting minor emotions.
