Abstract

A method for recording and reproducing a program in a TV/DVD recorder combo system is provided to reproduce a program only when a password is identical to a set password by selectively setting up a password in recording a television program on a DVD title, thereby preventing other people from watching the television program if a user wants. When recording a television program on a DVD title in a TV/DVD recorder combo system, it is judged whether a password is to be set up(S10,S20). If the password is to be set up, a password is inputted to be set up(S30). The corresponding program is recorded(S40). When reproducing a recorded program, it is judged whether a password is set up in the selected program(S50,S60). If a password is set up in the selected program, the password is received(S70). It is judged whether the received password is identical to the set password(S80). Only when the received password is identical to the set password, the selected program is reproduced(S90).

도 2는 본 발명에 의한 TV/DVD 레코더 콤보 시스템에서의 녹화 및 재생 방법을 설명하기 위한 흐름도이다. 2 is a flowchart illustrating a recording and reproducing method in the TV / DVD recorder combo system according to the present invention.

여기에 도시된 바와 같이 먼저, 텔레비전에서 방송되는 프로그램을 녹화하고자 할 경우 녹화할 프로그램에 비밀번호를 설정할 것인지 판단한다(S10)(S20). As shown here, first, when it is desired to record a program broadcast on the television, it is determined whether to set a password for the program to be recorded (S10) (S20).

이때, 해당 프로그램에 대해 비밀번호를 설정하여 다른 사람이 재생시킬 수 없도록 하고자 할 경우에는 비밀번호를 입력받아 입력된 비밀번호를 녹화되는 프로그램에 설정한다(S30). At this time, if you want to set the password for the program so that other people can not play it, the password is input and set the input password to the recorded program (S30).

이때 비밀번호가 설정된 경우에는 녹화되는 프로그램을 암호화하여 녹화함으로써 녹화된 DVD 타이틀을 다른 비밀번호를 사용하지 않는 DVD 플레이어에서 재생할 경우에도 재생할 수 없도록 할 수도 있다(S40). In this case, if a password is set, the recorded program may be encrypted and recorded so that the recorded DVD title cannot be played even when played on a DVD player that does not use another password (S40).

이렇게 방송 프로그램을 녹화할 때 프로그램에 대해 비밀번호를 부여함으로써 다른 사람이 함부로 보지 못하도록 보관할 수 있게 된다. When recording a program like this, a password can be assigned to a program so that it can be kept from being viewed by others.

이후, 비밀번호가 부여된 DVD 타이틀을 재생하고자 할 경우 선택적으로 녹화된 프로그램마다 비밀번호가 부여됨에 따라 재생할 프로그램을 선택한다(S10)(S50). Subsequently, when a password-titled DVD title is to be played back, a program to be played back is selected according to a password being provided for each selectively recorded program (S10) (S50).

이때 선택된 프로그램에 비밀번호가 설정되었는가 판단하여 비밀번호가 설정되지 않았을 경우에는 통상적인 방법에 의해 선택된 프로그램을 재생한다(S60)(S90). At this time, if it is determined that a password has been set for the selected program, and if the password has not been set, the selected program is played by the conventional method (S60) (S90).

그러나, 선택된 프로그램에 대해 비밀번호가 설정된 경우에는 비밀번호의 입력을 요청하게 되고(S70), 이때 입력된 비밀번호와 설정된 비밀번호가 일치할 경우 선택된 프로그램을 재생하여 볼 수 있도록 한다(S80)(S90). However, if a password is set for the selected program, a request for input of a password is requested (S70). At this time, if the input password and the set password match, the selected program can be played and viewed (S80) (S90).

이렇게 비밀번호가 설정된 프로그램에 대해 암호화하여 녹화하였을 경우 비밀번호가 일치함에 따라 암호화 방식에 따른 복호화를 수행하여 재생함으로써 원본 영상을 재생하여 시청할 수 있도록 한다. In the case where the encrypted program is recorded with the password set as described above, the original video can be played and viewed by decrypting according to the encryption method.

상기한 바와 같이 본 발명은 TV/DVD 레코더 콤보 시스템에서 텔레비전 프로그램을 DVD 타이틀에 녹화할 때 선택적으로 프로그램에 따라 비밀번호를 설정함으로써 재생시 비밀번호가 일치할 경우에만 재생되도록 함으로써 미성년자 관람불가의 프로그램을 녹화하였을 경우 미성년자의 관람을 방지할 뿐만 아니라 다른 사람이 보지 않기를 원하는 프로그램의 경우 안전하게 보관할 수 있는 이점이 있다. As described above, according to the present invention, when a television program is recorded on a DVD title in a TV / DVD recorder combo system, a password is selectively set according to the program so that it can be played only when the password is matched at the time of playback. If you do not only prevent the viewing of minors, there is an advantage that can be safely stored in the case of programs that other people do not want to see.
