Description
본 발명은 TVCR의 예약녹화방법에 관한 것으로서, 특히 TVCR을 이용하여 방송을 수신할 때 화면상에 방송예고 프로가 나올 경우에 사용자가 리모콘을 조작하여 화면 예약녹화키를 입력시키면 타이머의 제어에 의해 자동으로 그 예고화면을 저장한 후 그 화면중의 문자부분을 인식하여 방송시간을 알아내고 상기 방송시간이 도래하면 자동으로 녹화를 실행시킴으로써 사용자가 별도로 예약녹화 설정을 하지 않더라도 녹화하기 원하는 방송 프로그램을 편리하게 녹화시킬 수 있도록 한 ＴＶＣＲ의 예약녹화방법(Method for controlling a time recording of TVCR)에 관한 것이다.The present invention relates to a reservation recording method of a TVCR. Particularly, when a broadcast notification program appears on a screen when a broadcast is received using a TVCR, when a user inputs a screen reservation recording key by operating a remote controller, a timer is controlled. It automatically saves the notice screen, recognizes the character part of the screen to find out the broadcast time, and automatically executes recording when the broadcast time arrives. It relates to a method for controlling a time recording of TVCR that allows for convenient recording.
일반적으로, TVCR은 TV와 VCR을 일체형으로 만든 것으로서, 하나의 전원공급기에 의해 전원이 공급되고 상기 VCR을 제어하는 시스콘(SYSTEM CONTROL;SYSCON)과 TVCR 전체 시스템을 제어하는 타이머(TIMER)에 의해 각 구성요소가 동작되고 있으며, 텔레비전 방송신호의 기록 및 재생, 다른 녹화 테이프의 녹화 및 재생, 시청하지 않는 다른 채널의 방송녹화, 예약녹화 및 부재시 녹화 등을 위해 사용하는 기기이다.In general, a TVCR is an integrated TV and VCR, which are powered by a single power supply and are controlled by a SYSTEM CONTROL (SYSCON) that controls the VCR and a timer that controls the entire TVCR system. Each component is operated, and is a device used for recording and reproducing television broadcast signals, recording and reproducing other recording tapes, broadcasting recording of other channels not being watched, reserved recording, and absent recording.
즉, 녹화 테이프에 녹화하는 기록의 경우에는 현재 무신호인 경우에도 바이어스 자계에 의한 잔류자기가 없기 때문에 잡음이 적은 교류바이어스 방법이 채택되고 있으며, 오디오 신호의 기록은 그 주파수 범위가 20-20000Hz정도로 비교적 좁고, 위상관계를 그다지 문제삼지 않아도 되기 때문에 상기 교류바이어스 방법이 행해지고 있다. 하지만, 영상신호의 기록에 있어서는 그 주파수 범위가 0-4MHz정도로 넓고, 파형을 충실히 재현하기 위해 엄격한 위상특성이 요구되기 때문에 주파수 변조(FM) 기록방식이 채용되고 있다.That is, in the case of recording on a recording tape, an AC bias method with low noise is adopted since there is no residual magnetic field due to a bias magnetic field even in the absence of a signal, and the recording of an audio signal has a frequency range of about 20-20000 Hz. The AC bias method is performed because it is narrow and the phase relationship does not have to be so much a problem. However, the frequency modulation (FM) recording method has been adopted for recording video signals because its frequency range is wide, about 0-4 MHz, and strict phase characteristics are required to faithfully reproduce waveforms.
이와 반대로, 재생시는 기록된 자기 테이프를 자기 헤드의 갭에 접속시키면서 주행시키게 되고, 상기 자기 헤드에 의해 읽혀진 신호가 증폭 및 처리되어 수상관 및 스피커를 통하여 재생된다.On the contrary, during reproduction, the recorded magnetic tape is driven while being connected to the gap of the magnetic head, and the signal read by the magnetic head is amplified and processed and reproduced through the water pipe and the speaker.
위와같은 TVCR로 예약녹화를 하고자 할 때에는 우선, 사용자가 리모콘을 조작하여 예약녹화 기능키를 누르면 이에 해당되는 제어신호를 인가받은 타이머가 TVCR의 CRT부를 통해 예약녹화설정 메뉴화면을 디스플레이시키고 이때 사용자가 리모콘을 조작하여 상기 메뉴화면을 통해 녹화채널, 녹화날짜, 녹화시작시간/끝시간, 녹화속도 등을 설정하게 된다. 이러한 설정작업이 완료된 후 예약녹화 시작시간이 도래하면 설정된 녹화 끝시간까지 녹화모드를 실행하게 된다.When you want to make a reservation recording with the TVCR as above, first, if the user operates the remote control and presses the reservation recording function key, a timer that receives the corresponding control signal displays the reservation recording setting menu screen through the CRT unit of the TVCR. By operating the remote control, the recording channel, recording date, recording start time / end time, recording speed, etc. can be set through the menu screen. When the scheduled recording start time arrives after this setting is completed, the recording mode is executed until the set recording end time.
따라서, 종래에는 예약녹화를 하려면 상기와 같이 사용자가 일일이 리모콘을 조작하여 예약녹화설정 메뉴화면에 설정데이터를 입력시켜야 되는 불편함이 있었다.Therefore, in the related art, in order to make a reservation recording, there is an inconvenience in that the user must input the setting data on the reservation recording setting menu screen by operating the remote controller as described above.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, TVCR을 이용하여 방송을 수신할 때 화면상에 방송예고 프로가 나올 경우에 사용자가 리모콘을 조작하여 화면 예약녹화키를 입력시키면 타이머의 제어에 의해 자동으로 그 예고화면을 저장한 후 그 화면중의 문자부분을 인식하여 방송시간을 알아내고 상기 방송시간이 도래하면 자동으로 녹화를 실행시킴으로써 사용자가 별도로 예약녹화 설정을 하지 않더라도 녹화하기 원하는 방송 프로그램을 편리하게 녹화시킬 수 있도록 한 TVCR의 예약녹화방법을 제공하는데 그 목적이 있다.The present invention is to solve the above problems, when the broadcast notification program is displayed on the screen when receiving a broadcast using a TVCR when the user inputs the screen reservation recording key by operating the remote control under the control of the timer It automatically saves the notice screen, recognizes the character part of the screen to find out the broadcast time, and automatically executes recording when the broadcast time arrives. An object of the present invention is to provide a scheduled recording method of a TVCR for convenient recording.
본 발명의 목적을 달성하기 위한 기술사상으로서, 방송프로 예고화면이 TV로 방송되는 도중에 화면예약녹화키가 입력되면 메모리수단에 방송프로 예고화면을 저장시키는 과정과, 방송프로 예고화면에 있는 문자를 인식하여 녹화시작 시간 및 끝시간을 체크하는 과정과, 주기적으로 방송프로의 시작시간을 확인하여 시작시간이 도래하면 방송프로 끝시간까지 녹화를 실행시키는 과정을 수행하는 발명이 제시된다.As a technical idea for achieving the object of the present invention, if the screen reservation recording key is input while the broadcast program preview screen is broadcast on TV, the process of storing the broadcast program preview screen in the memory means, and the characters on the broadcast program preview screen The present invention is proposed to perform a process of recognizing and checking a recording start time and an end time, and periodically checking the start time of a broadcast program to execute recording until the end time of the broadcast program.

상기와 같이 구성된 시스템에 의해 구현되는 본 발명의 처리과정을 도 2의 흐름도를 참조하여 설명하면 다음과 같다.The process of the present invention implemented by the system configured as described above will be described with reference to the flowchart of FIG. 2.
먼저, 사용자가 TVCR의 파워를 온 시켜 TV 시청을 하고 있으면 타이머(17)는 현재 모드가 TV 시청모드인지 확인하고 대기상태에 있게 된다(S100).First, if the user is watching TV by turning on the power of the TVCR, the timer 17 checks whether the current mode is the TV viewing mode and is in the standby state (S100).
TV 시청도중 특정 방송프로 예고화면이 방송되었을 때 사용자가 이 방송프로를 예약녹화하고 싶다면 리모콘(18)의 화면예약녹화키를 누르면 된다.If the user wants to record the broadcast program when a specific broadcast program notice screen is broadcast while watching TV, the user presses the screen reservation record key of the remote controller 18.
즉, 사용자가 리모콘의 화면예약녹화키를 누르게 되면 이에 해당되는 제어신호가 광신호로 송출되고 이를 인가받은 리모콘 수신부(도면에 미도시)는 다시 타이머(17)에 이 제어신호를 보내게 되는데 이때, 상기 타이머(17)는 현재 화면예약녹화키가 입력되었는지 확인한 후 입력되었다고 확인되면 방송프로 예고화면을 메모리부(22)에 저장시키게 된다(S101, S102).That is, when a user presses the screen reservation recording key of the remote control, the corresponding control signal is transmitted as an optical signal, and the remote controller receiving unit (not shown) that receives the signal sends the control signal to the timer 17 again. In operation S101 and S102, the timer 17 checks whether the current screen reservation recording key is input and then confirms that the screen is recorded in the memory unit 22 (S101 and S102).
상기의 방송프로 예고화면이 저장되면 타이머(17)는 방송프로 예고화면에 기록되어 있는 문자 및 숫자를 인식하여 해당 방송프로의 시작시간 및 끝시간을 체크하게 된다(S103, S104).When the broadcast program preview screen is stored, the timer 17 recognizes letters and numbers recorded on the broadcast program preview screen and checks the start time and the end time of the broadcast program (S103, S104).
소정시간이 경과된 후에 방송프로 시작시간이 도래되면 타이머(17)가 이를 확인한 후에 시스콘(19)에 제어신호를 보내고 이에 따라 상기 시스콘(19)은 데크부(16)를 제어하여 녹화를 실행시키게 된다(S105, S106).After the predetermined time has elapsed, if the broadcast program start time arrives, the timer 17 checks this and then sends a control signal to the scissor 19. Accordingly, the sciscon 19 controls the deck unit 16 to perform recording. It executes (S105, S106).
한편, 녹화가 소정 시간 실행되다가 방송프로의 끝시간이 도래하면 타이머(17)는 다시 이를 확인한 후 시스콘(19)에 제어신호를 보내고 상기 시스콘(19)이 데크부(16)를 제어하여 녹화모드를 해제시키게 된다(S107, S108).On the other hand, when the recording is executed for a predetermined time and the end time of the broadcast program arrives, the timer 17 checks again and sends a control signal to the sheath cone 19 and the sheath cone 19 controls the deck unit 16. The recording mode is released (S107, S108).
이상의 설명에서 알 수 있는 바와 같이, 본 발명은 방송프로 예고화면이 TV로 방송되는 도중에 사용자가 화면예약녹화키를 누르면 타이머(17)가 메모리부(22)에 방송프로 예고화면을 저장시킨 후 방송프로 예고화면에 있는 문자를 인식하여 녹화시작 시간 및 끝시간을 체크하고 계속해서 주기적으로 방송프로의 시작시간을 확인하여 시작시간이 도래하면 시스콘(19)에 제어신호를 보내 방송프로 끝시간까지 녹화를 실행시킴으로써 사용자가 별도로 예약녹화 설정을 하지 않더라도 녹화하기 원하는 방송 프로그램을 편리하게 녹화시킬 수 있다.As can be seen from the above description, in the present invention, when the user presses the screen reservation recording key while the broadcast program preview screen is broadcasted on a TV, the timer 17 stores the broadcast program preview screen in the memory unit 22 and then broadcasts the broadcast. Recognizes the characters on the pro notice screen, checks the recording start time and end time, and continuously checks the start time of the broadcast program. When the start time arrives, the control signal is sent to the system console 19 until the end of the broadcast program. By executing the recording, the user can conveniently record the broadcast program that he / she wants to record even if the user does not set the schedule recording separately.
