BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parental control technology in a video player, and more particularly, to a parental control method of a video player suitable for applying an individual parental control to user-produced user content.

In the A / V device using a conventional analog system, there is no control method and means for controlling the interaction between the A / V device and other A / V devices connected and connected to each other. In order to control, a user has to input separate operation control keys to the A / V device, respectively.

However, A / V devices using current digital methods, such as compact disc (CD) or mini disc (MD) players, which are digital audio data recording media, use the IEEE 1394 interface, which is a digital communication interface. By connecting to another A / V device, the digital data transmission and operation control between the A / V devices is performed by using a command set defined in advance.

In general, an optical disc, which is a large-capacity recording medium capable of recording and storing digital data such as audio or video tape, is a recording disc for reproduction only, such as CD-ROM and DVD-ROM, and one-time recording such as CD-R and DVD-R. There are optical discs capable of this, and rewritable optical discs such as CD-RW, DVD-RAM, and DVD-RW.

In recent years, DVD (Digital Versatile Disc), which is a large-capacity, high-density optical disc capable of recording and storing high-definition video data or high-quality audio data for a long time, has been widely used. It may be connected to a display device such as a TV through a digital communication interface. In the case of a DVD player, such an MPEG codec is provided within the DVD player, so that various ports can be easily connected, and the user can efficiently edit and produce still images and movies by using the MPEG codec.

On the other hand, the DVD title can record a plurality of sub-titles from the large capacity feature of the DVD, and the DVD title reproducing apparatus supports to selectively display a plurality of sub-titles recorded in the DVD title. The DVR also supports the ability to copy desired sub-titles together when recording DVD titles onto DVD discs.

In particular, as the prevalence of DVRs that can record information on DVD discs increases, the production and editing of DVD discs in addition to the sub-title information input function is expected to be easily implemented in general homes.

On the other hand, the conventional video reproducing apparatus is limited to play the video through a rating or only a password. Or, it could be restricted to play the video only through the password of the genuine playback media.

Current playback apparatuses do not simply play genuine video, but can also play back video content produced by a user, such as video content recorded using a DVD-RW. However, the separately produced content cannot be separately restricted except for the method of directly locking the content at the time of initial production. There is a problem that can not be limited.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and has a USB port in a video playback device, and the parental control method of the video playback device that can impart a parental control function for individual video contents using an external USB memory. The purpose is to provide.

According to a preferred embodiment of the present invention for achieving the above object, as a method of limiting the viewing of the video playback device, storing the password associated with the serial number of the video playback device via a USB memory, and the video playback device and USB A method of restricting viewing of a video reproducing apparatus comprising connecting the memory to play the video contents only when a password stored in the USB memory is confirmed at the time of reproducing the arbitrary video contents.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. In the following description of the reference numerals to the components of the drawings, it should be noted that the same reference numerals as much as possible even if displayed on different drawings.

The present invention breaks away from the technique of granting the parental control function only when recording the video content, so that the parental control can be restricted at any time according to the user's request using the password in the USB memory even when the video content is played back. From the above, the object of the present invention can be easily achieved.

1 is a diagram illustrating a connection between a video player and a USB memory for implementing a parental control method according to an embodiment of the present invention.

As shown in FIG. 1, in this embodiment, the USB port 102 is provided at a predetermined position on the front panel of the video player 100, and the USB memory 104 can be inserted through the USB port 102. By providing a parental control function for the video content to be played back.

That is, in the present invention, after downloading a lock key through a service center server (not shown) or the like, input a serial number of a video player, set a personal password, and store it in the USB memory 104. After inserting the USB memory 104 into the video player 100, the video content can be played only when the authentication is successful after the password update, the password check, and the like.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figures 2 and 3 attached to the parental control process of the video player according to a preferred embodiment of the present invention will be described in detail.

First, Figure 2 is a method for upgrading the password for the playback of the video content and determine whether viewing restrictions on the video playback device itself, the user is connected to the service center server is given a personal password and upgrade the password to the video playback device The process is shown.

As shown in FIG. 2, in steps S200 and S202, a personal password is provided by inputting a serial key of a video player through a service center server. The password thus granted is stored in the USB memory 104.

In operation S204, the USB memory 104 is inserted into the image reproducing apparatus 100, and then a password upgrade process is performed.

Subsequently, in step S206, it is determined whether the serial number of the image reproducing apparatus 100 and the serial number stored in the USB memory 104 match, and if it does not match, the process proceeds to step S208 to display the re-registration or reset phrase. Output to a display device (not shown) connected to the playback device.

If the serial number is the same as the result of the determination in step S206, it is determined whether the functions such as authenticity of video content, image change, illegal video check, and privacy protection are set (S210) (S212) (S214) (S216). If at least one of these conditions is satisfied, a lock of the video player is set.

On the other hand, in step S218, it is determined whether a lock is set at the time of reproducing the video reproducing apparatus, and if the lock is set, the process proceeds to step A; otherwise, the process proceeds to step S220 to reproduce the video content.

3 is a subsequent procedure of Process A, which illustrates a viewing restriction process of video content using a USB memory according to a preferred embodiment of the present invention.
