Abstract

A method for limiting the viewing of a recording image in an image signal recording/reproducing apparatus is provided to allow a user to view a recorded image object according to a grade suitable for the user by skipping or reproducing a viewing limit marked interval of the recorded image object whose reproduction is requested to correspond to the viewing grade of the user. A control unit records a recording-requested image object in a storing medium of an image device(S200). The control unit receives a viewing grade display request for the recorded image object, and marks a corresponding interval by a requested grade(S202,S204,S206). When the marked recorded image object is reproduced(S208), the control unit skips or reproduces an interval which is marked in the recorded image object to correspond to viewing grade information of a user(S210,S214,S216).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video signal recording / reproducing apparatus, and more particularly, to a method of restricting viewing of recorded video according to a rating set by a user in a video signal recording / reproducing apparatus.

In general, a video signal recording / reproducing apparatus refers to a device that records various broadcast signals on a storage medium such as a video cassette recorder (VCR) or a digital versatile disk (DVD), or reproduces the recorded video signals through a TV receiver. Recently, it has been developed as a complex device with a built-in HDD (Hard Disk Drive) to record a large amount of video signals, such as TV.

Among the above video signal recording / playback devices, especially HDD-type HDD-DVDR system with built-in HDD, plays a lot of DVD disks mounted on the loader, and at the same time the video data that needs to be backed up among the large-capacity video data stored in HDD With the DVD-RW function, it is also possible to back up to a DVD-RW disc loaded in the loader, and the demand is increasing along with the DVD-RW.

On the other hand, for the broadcast signal recorded in the video signal recording / playback time, such as HDD-DVDR system with a built-in HDD as described above, the viewing restriction method for limiting the viewing of adult video content by using the rating information contained in the broadcast signal Is being proposed.

However, in the conventional video signal recording / reproducing apparatus, the parental control method for the recorded video sets a password for the entire video recorded by the user, or deletes some sections of the recorded video by editing. In addition, the user is allowed to perform the viewing restriction, and the user judges the video section requiring the viewing restriction during the recording of the broadcasting signal, and assigns and marks the graded viewing grade based on the age group, so that the user can watch the recorded video. Active viewing restrictions such as the ability to watch all marked sections on the video or to exclude some marked sections according to the ratings of each star are not implemented.

Accordingly, an object of the present invention is to provide a method for restricting viewing of a recorded video object according to a rating set by a user in a video signal recording / reproducing apparatus.

According to an aspect of the present invention, there is provided a method for restricting viewing of a recorded video in a video signal recording / reproducing apparatus, the method comprising: (a) recording a video requested to be recorded on a storage medium of the video apparatus; and (b) Receiving a viewer rating display request for the video image and performing the marking in the requested grade for the corresponding section, and (c) When playing the recorded video recorded with the viewer rating, the recorded video material corresponding to the audience rating information of the user And skipping or reproducing the portion marked at.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

Hereinafter, referring to FIG. Operation in each component for performing parental control will be described in detail.

First, during recording, the DSP (digital signal processor) 106 adds additional data for an error correction code (ECC) to the coded data and modulates it by a predetermined modulation scheme.

The RF amplifier 104 amplifies the electrical data input from the DSP unit 106 and converts it into an optical signal. The pickup section 102 incorporates an actuator for focusing and tracking, and records the optical signal converted by the RF amplifier section 104 on a disc.

The servo 108 receives the information necessary for servo control from the DSP 106 through the RF amplifier 104 and the controller 112 to perform stable servo. The control unit 112 controls the overall operation of the entire system and transmits data to the disc through the DSP unit 106, the RF amplifier 104, and the pickup unit 102 according to the user's key input through the key input unit 114. Record it.

Next, during reproduction, the pick-up 102 reads out the optical signal from the disk storing the data. The RF amplifier 104 converts an optical signal output from the pickup unit 102 into an electrical signal and extracts a servo signal and modulated data for performing servo.

The DSP unit 106 demodulates the data modulated by the RF amplifier 104, removes additional data while correcting an error by performing ECC, and picks up the pickup unit according to the actuator up / down command of the controller 112. A signal for driving the lens actuator is generated at 102. The servo unit 108 receives information necessary for servo control from the RF amplifier 104 and the controller 112 and performs stable servo.

The HDD recording / reproducing unit 116 converts the video data signal input under the control of the control unit 112 into a hard disk recording format and records the same on the HDD 118, and backs up data to new DVD media in the DVD loader. During playback for back-up, binary data read from HDD 118 is restored to video data and applied to new DVD media in the loader.

The controller 112 controls the overall operation of the entire DVD system and controls the DSP unit 106, the RF amplifier 104, and the pick-up 102 according to a user's key input. Data is recorded on the disc) or data is reproduced from the DVD recording / playback disc 100. In addition, the control unit 112 marks the above-mentioned marking information by marking a parental level on the required section of the recorded video according to the grade based on the age group of the user for the recorded video according to an embodiment of the present invention. 118), and when a playback request of the recorded video recorded above is requested, each user can record or record the recorded video at a level suitable for each user by skipping or playing a parental control-marked section of the requested recorded video corresponding to the user's viewing grade.
