Abstract

본 발명은 비디오 카세트 테이프의 암호화 방법에 관한 것으로서, 자기 기록 재생장치의 자체에 비밀번호를 세팅하지 않고 비밀 유지를 위한 각각의 비디오 카세트 테이프마다 암호를 세팅하여 그 해당 테이프의 로딩시에만 비밀번호를 입력하여 녹화 또는 재생등의 동작을 수행하도록 한 것이다.The present invention relates to a method of encrypting a video cassette tape, in which a password is set for each video cassette tape for maintaining confidentiality without setting a password in itself, and a password is input only when the corresponding tape is loaded Recording, or reproduction.

이와 같은 본 발명은 비디오 카세트의 적소에 메모리를 취부하여 그 카세트 로딩시 키이입력수단으로부터의 암호기록 키이입력여부를 검색하는 단계와; 상기 암호기록 키이입력이 있으면 자체램의 임의 바이트를 설정하여 이에 키이입력수단으로부터의 입력되는 번호키이를 순차적으로 저장하는 단계와; 이후 번호키이 입력이 완료되면 상기 저장된 번호키이 데이터를 인터페이스수단 및 이와 전기적으로 접촉된 전기접촉부재를 통해 직렬 출력하여 비디오 카세트의 메모리에 기록하는 단계와; 상기 기록된 암호 데이터를 판독하여 키이입력수단으로부터 입력된 키이데이타와의 비교로 비디오 카세트를 이젝트 또는 정상동작을 수행하는 단계로 이루어짐을 특징으로 한다.The present invention provides a method of controlling a video cassette player, comprising the steps of: mounting a memory at a proper position of a video cassette and retrieving whether or not a password recording key is input from the key input means when the cassette is loaded; Setting an arbitrary byte of the own RAM if the password recording key is input, and sequentially storing the inputted number key from the key input means; When the input of the number key is completed, the stored number key data is serially output through the interface means and the electrical contact member electrically connected to the stored number key data and is recorded in the memory of the video cassette; Reading the recorded encrypted data, and ejecting the video cassette or performing a normal operation by comparing the encrypted data with key data input from the key input means.

How to encrypt video cassette tapes

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제5도는 제2도에 따른 비디오 카세트 암호화 방벙의 신호흐름도로서, 제5a도는 메모리에 암호를 기록하는 과정을 보인 신호흐름도.FIG. 5 is a signal flow diagram of a video cassette encryption scheme according to FIG. 2, wherein FIG. 5a is a signal flow diagram showing the process of recording a password in a memory.

제5b도는 메모리의 암호를 판독하는 과정을 보인 신호흐름도이다.5b is a signal flow diagram illustrating the process of reading the encryption of the memory.

Claims

Loading a memory at a proper position of the video cassette and retrieving whether or not a password recording key is input from the key input means when the cassette is loaded; Setting an arbitrary byte of the self-RAM if the password recording key is input, and sequentially storing the inputted number key from the key input means; And when the input of the number key is completed, the stored number key data is serially outputted through the interface means and the electrical contact member electrically in contact with the stored number key data, and then recorded in the memory of the video cassette .

The method of claim 1, wherein the arbitrary byte is 4 bytes.

Loading a memory at a proper position of the video cassette, reading the encrypted data recorded in the memory when the cassette is loaded, and storing the encrypted data in its own RAM; Displaying on the screen of the monitor after the password is read out whether or not a password is input on an on-screen character and receiving a password from the key input means; Retrieving the input encrypted encrypted data, and performing an eject or normal operation according to the retrieved encrypted data.
