In the video recording and reproducing method capable of viewing by grade, the viewing function by grade is selected. Determining whether the recording mode is the reproduction mode or the recording mode if the user grade is designated; In the first process, a grade code designated by a user is inserted into the video signal in the recording mode, and the second process of muting and unmuting the screen according to the presence or absence of the determined grade code in the reproduction mode.

Description

Video recording and reproducing apparatus with rating viewing function and its method

The present invention relates to a video recording and reproducing apparatus, and more particularly, to provide a video recording and reproducing apparatus that designates a class code according to the video content and reproduces and records a video signal according to the class code.

Generally, when watching TV and video entertainment at home, there are many scenes that minors should not watch, which causes problems for minor education. Conventional video entertainment such as TVs and video tape recorders have a problem in that they are output as they are even if the scene is not available for minor viewing.

The technical problem to be achieved by the present invention is to provide a device for automatically muting or skipping a moment when the scene is impossible to minor in the video system.

Another technical problem to be achieved by the present invention is to provide a method for automatically muting or skipping a moment when an image of a minor is impossible in a video system.

1 is a block diagram showing a video recording and reproducing apparatus to which a rating function is added according to the present invention.

2 is a flowchart illustrating a video recording and reproducing method to which a viewing function for each grade is added in the controller of FIG. 1 according to the present invention.

In order to solve the above technical problem, an image recording and reproducing apparatus capable of viewing grades, the apparatus comprising: an image signal reproducing unit reproducing an image signal into which a grade signal is inserted; Determining the grade code inserted into the image signal reproduced by the image signal reproducing unit or inserting a grade code designated by the user into the image signal, and mute or mute the image signal generated by the image signal reproducing unit according to a predetermined command A grade code processing unit; An image signal recording unit for recording an image signal output from the grade code processor; And a control unit for commanding a video signal mute and a mute release command according to a comparison of a grade code determined by the grade code processor and a grade code designated by a user.

In order to solve the above other technical problem, a video recording and reproducing method capable of viewing by grade, comprising: a first step of determining whether the recording mode is selected when the viewing function by rating is selected and the user grade is designated; And a second step of inserting a rating code designated by a user into the video signal in the recording mode in the first step, and muting and releasing the screen according to the presence or absence of the determined rating code in the playback mode. A video recording and playback method with a function added.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing a video recording and reproducing apparatus to which the viewing function for each grade is added according to the present invention. The video signal reproducing unit 130 for reproducing the video signal by the head records and discriminates the grade code by the TV signal. A grade code processor 120, a controller 110 for exchanging control data with the grade code processor 120, and an image signal recorder 140 for recording an image signal output from the grade code processor 120. .

First, in order to implement the present invention, a producer assigns a grade code to a video signal according to each content during TV broadcast production and video soft production. For example, a grade 1 student is an elementary school student or younger, a class 2 student or less a high school student, and a class 3 student is an adult.

As illustrated in FIG. 1, the image signal reproducing unit 130 scans and reproduces an image signal recorded in the image signal recording unit 140 with a head. The grade code processor 120 determines the grade code inserted into the image signal reproduced by the image signal reproducing unit 130 and outputs it to the control unit 110 or reproduces the grade code by the TV signal specified by the user during recording. It is inserted into the video signal generated by the unit 130, and the video signal generated by the video signal reproduction unit 130 by the video signal mute and mute release data generated in the control unit 110 to mute or mute. The controller 110 compares the grade code determined by the grade code processor 120 with the grade code designated by the user, and outputs the image signal mute and mute release data to the grade code processor 120 according to the result. The video signal recorder 140 records the video signal output from the grade code processor 120 on a recording medium.

2 is a flowchart illustrating a video recording and reproducing method to which a viewing function for each grade is added in the controller 110 of FIG. 1 according to the present invention.

As illustrated in FIG. 2, in operation 210, a user's selection to perform a viewing function for each grade or to watch the original signal as is is determined. If the user selects a rating function according to the rating, it is determined whether the user rating is designated in step 220. Otherwise, the screen mute is canceled in step 270. If the user level is specified, the process determines whether the current video device is in the playback mode or the recording mode in step 230, and in step 270, the screen mute is released. In the recording mode, the rating code designated by the user can be inserted and recorded in the video signal in step 290. In the playback mode, the presence or absence of the rating code determined in step 250 is determined. If the rating code does not exist, the screen mute is released in step 270 so that the original signal can be viewed as it is. If the rating code exists, the rating code determined by the user is compared with the rating code designated by the user in step 260. If the determined grade is less than or equal to the specified grade in step 260, the screen mute data is output (280). If the determined grade is greater than or equal to the specified grade, the screen mute release data is output (270).

The present invention is not limited to the above-described embodiment, and of course, modifications may be made by those skilled in the art within the spirit of the present invention.

As described above, according to the present invention, it is possible to automatically mute or skip an instant when a minor impossible scene is applied to a video device such as a TV or a video tape recorder.
