Abstract

본 발명은 ATF(Auto Track Find) 주파수를 이용하여 영상신호를 녹화 및 재생시키는 장치에 있어서, 비밀번호입력에 의해 ATF주파수를 변화시켜 녹화하고 재생시 비밀번호입력이 있는 경우에만 정상적인 재생이 가능하도록 하는 비밀번호를 이용한 녹재 방법 및 장치에 관한 것으로, 본 발명은 녹화동작시 비밀번호 입력이 있으면 기존 ATF주파수를 비밀번호 입력에 상응한 새로운 ATF주파수로 변환시켜 영상신호를 녹화시키고, 재생동작에 비밀번호와 몇 개 트랙의 ATF주파수를 변환시킨 비밀번호를 비교하여 일치할 경우만 정상적인 재생동작을 수행시킴으로써 이루어진다.The present invention is a device for recording and playing back video signals using ATF (Auto Track Find) frequency, the password to change the ATF frequency by the password input and to record and play back only when there is a password input during playback password The present invention relates to a method and apparatus for recording a tree using the present invention. The present invention records a video signal by converting an existing ATF frequency into a new ATF frequency corresponding to a password input when there is a password input during a recording operation. This is achieved by performing normal playback only if the passwords of ATF frequency are compared and matched.

영상기록 재생장치의 영상기록 재생방법에 있어서, 녹화동작시 비밀번호 입력모드가 선택되었는가를 판단하여 비밀번호 입력모드가 아니면 기존 방식대로 녹화시키고 비밀번호 입력모드이면 비밀번호 입력을 체크하는 단계와, 비밀번호 입력이 있으면 이에 상응한 새로운 ATF주파수를 발생시켜 영상신호를 녹화시키는 단계와, 재생시 비밀번호 입력이 있는가를 체크하는 단계와, 비밀번호 입력후 재생동작시키면 몇 개 트랙을 읽고 기록된 ATF주파수를 검출하는 단계와, 검출된 ATF주파수를 비밀번호로 변환시켜 입력된 비밀번호와 동일하면 재생동작을 수행하고 틀리면 재생동작을 중단시키는 단계를 수행시키는 것을 특징으로 하는 비밀번호를 이용한 녹재 방법.In the video recording and playback method of the video recording and playback apparatus, judging whether the password input mode is selected at the time of the recording operation. Generating a new ATF frequency corresponding to it, recording a video signal, checking whether there is a password input during playback, reading a number of tracks and detecting the recorded ATF frequency when the password is played back. And converting the ATF frequency into a password and performing the regeneration operation if the password is the same as the input password, and stopping the regeneration operation if it is wrong. 영상기록 재생장치에 있어서, 녹화동작시 비밀번호 입력에 상응한 ATF주파수 발생 명령을 내리고 재생동작시 입력 비밀번호와 ATF주파수를 변환시킨 비밀번호를 비교하여 일치되는 경우만 재생동작을 수행시키는 마이콤과, 마이콤의 ATF주파수 발생 명령에 따라 ATF주파수를 다르게 발생시켜 영상신호를 기록하는 ATF부와, 재생시 기록된 ATF주파수를 읽어 비밀번호로 변환시키기 위해 마이콤에 인가시키는 ATF주파수 검출기를 구비하여 이루어지는 것을 특징으로 하는 비밀번호를 이용한 녹재 장치.In the video recording and reproducing apparatus, when a recording operation is executed, a command for generating an ATF frequency corresponding to a password input is issued. A password generated by generating an ATF frequency differently according to the ATF frequency generation command and an ATF unit for recording an image signal, and an ATF frequency detector configured to apply to a microcomputer to read and convert the recorded ATF frequency into a password.
