Abstract

본 발명은 영상기록매체에 관한 것으로 특히, 영상기록매체의 재생을 제한할 수 있도록 하는 영상기록매체의 재생제어 장치 및 그 방법에 관한 것이다. 그러나, 종래의 영상기록매체의 경우, 제3자가 그 영상기록매체를 플레이어를 이용하여 재생해 볼 경우, 개인의 사생활 침해 문제 또는 기업보안에 관한 문제점을 야기시킬 수 있으며, 성인용 영화 또는 성인용 게임을 수록한 영상기록매체의 경우에는 미성년자에게 노출될 수 있다는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording medium, and more particularly, to an apparatus and method for controlling playback of an image recording medium, which can restrict playback of an image recording medium. However, in the case of a conventional video recording medium, when a third party plays the video recording medium using a player, it may cause personal privacy infringement problems or corporate security problems, and it may cause adult movies or adult games. In the case of recorded image recording media, there was a problem that it could be exposed to minors.

본 발명은 영상기록매체(1)에 수록된 고유정보와 상기 고유정보에 대응되는 억세스 제한 정보를 저장하는 기억수단(2)과, 상기 기억수단(2)에 저장된 억세스 제한정보를 입력 또는 정정시키는 억세스 제한정보 입력수단(3)과, 영상기록매체(1)를 플레이어에서 플레이시 영상기록매체(1)에 수록된 고유정보와 기억수단(2)에 저장된 고유정보를 비교하여 영상기록매체(1)에 대한 억세스를 제어하는 제어부(4)와, 상기 제어부(4)의 제어에 의해 영상기록매체(1)에 저장된 데이타를 읽어오는 콘트롤러(5)와 상기 콘트롤러(5)에서 전송된 영상 및 음성데이타를 디코딩하는 디코더부(6)로 구성하여, 영상기록매체(1)를 재생시키는 플레이어의 기억수단(2)에 억세스 제한정보를 저장할 수 있는 억세스 제한정보 키로 하여금 CD-I 타이틀의 레이블 영역 중에서 볼륨 ID와 볼륨 공간 크기를 고유정보를 하고 상기 고유정보와 억세스 제한정보를 하나의 억세스 제한 레코드로 구성하여 기억수단(2)에 저장시키고 억세스 제한 입력키를 이용하여 억세스 제한 레코드를 설정, 변경 및 삭제하도록 하여 영상기록매체(1)의 재생을 제한할 수 있도록 하여 제3자로 하여금 개인의 사생활 침해를 방지하며 귀중한 정보가 외부로 유출되는 것을 방지하여 줄 수 있는 유용한 것이다.The present invention provides a storage means (2) for storing the unique information contained in the video recording medium (1) and access restriction information corresponding to the unique information, and an access for inputting or correcting the access restriction information stored in the storage means (2). When the restriction information input means 3 and the video recording medium 1 are played in the player, the unique information stored in the video recording medium 1 and the unique information stored in the storage means 2 are compared to the video recording medium 1. A controller 4 for controlling access to the controller; a controller 5 for reading data stored in the video recording medium 1 under the control of the controller 4; and video and audio data transmitted from the controller 5. And an access restriction information key configured to decode the decoder unit 6 to store the access restriction information in the storage means 2 of the player which reproduces the video recording medium 1, thereby providing a volume ID in the label area of the CD-I title. And ball The space size is unique information, and the unique information and access restriction information are configured into one access restriction record and stored in the storage means 2, and the access restriction record is set, changed, and deleted by using the access restriction input key. By limiting the playback of the recording medium 1, it is useful for a third party to prevent invasion of personal privacy and to prevent valuable information from leaking to the outside.

Claims

Storage means (2) for storing the unique information contained in the video recording medium (1) and the access restriction information corresponding to the unique information, and access restriction information for inputting or correcting the access restriction information stored in the storage means (2). Means for accessing the video recording medium 1 by comparing the means 3 and the unique information stored in the video recording medium 1 with the unique information stored in the storage means 2 when the video recording medium 1 is played in the player. A controller 4 for controlling, a controller 5 for reading data stored in the video recording medium 1 under the control of the controller 4, and decoding of video and audio data transmitted from the controller 5; A playback control apparatus for a video recording medium, characterized by comprising a decoder (6).

Mounting the image recording medium 1 on the tray (S10), and then checking whether the access restriction information for the unique information of the image recording medium 1 is stored in the storage means (S20); Since the access restriction information is not stored in (2), the storage means 2 stores the access restriction information record in which the unique means for the video recording medium 1 and the access restriction information are combined. Step S30, checking whether the access restriction information input means 3 is entered (S40), and access restriction information input means 3 for changing and modifying the access restriction information, thereby access restriction information A conversion step (S50) for converting the data, a step (S60) for determining whether a play key is input, and the video recording medium (1) in the storage means (2) generates unique information and access restriction information as the play key is input. Check step (S70) to check, and the image Reproduction control method of the image recording medium characterized in that it consists of a step (S80) for reproducing the recording media (1).
