Abstract

본 발명은 DVD시스템의 페어렌탈레별(PARENTAL LEVEL) 변경을 위한 리셋장치에 관한 것이다. 본 발명은 시스템 구입시 제공되는 데모(DEMO)용 디스크에, 타사의 그리고 상업용의 일반적인 디스크와는 구별되는 소정의 데이타를 기록하여 두었다가 재생시 이 데이타를 검출하므로서 비밀번호를 리셋할 수 있도록 한다. 이와 같은 본 발명은 기저장되어 있는 비밀번호를 리셋할 수 있는 새로운 방법을 제시하는 효과를 갖는다.The present invention relates to a reset device for changing a parental level of a DVD system. In the present invention, predetermined data, which is different from a general disk of a third party or a commercial, is recorded on a DEMO disk provided at the time of purchase of the system, and the password is reset by detecting this data during playback. The present invention has the effect of suggesting a new method for resetting the stored password.
