Description

ＴＶＣＲ의 예약녹화 제어방법How to control reservation recording of TV

본 발명은 TVCR의 예약녹화 제어방법에 관한 것으로서, 특히 TVCR을 이용하여 예약녹화하는 경우에 일단 예약 설정된 방송 프로그램이 녹화완료된 후 소정시간이 경과한 후에 다시 소정 시간동안 처음과 같은 방식으로 예약 녹화할 수 있도록 함으로써 사용자에게 좀 더 다양하고 편리한 녹화방법을 제공할 수 있도록 한 ＴＶＣＲ의 예약녹화 제어방법(Method for controlling a time recording of TVCR)에 관한 것이다.The present invention relates to a method of controlling a reservation recording of a TVCR. Particularly, in case of a reservation recording using a TVCR, a reservation recording is performed for the first time after a predetermined time elapses after the scheduled program has been recorded. The present invention relates to a method for controlling a time recording of TVCR that allows users to provide a more diverse and convenient recording method.

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 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. Through the menu screen, a recording channel, a recording date, a recording start time / end time, a recording speed, and the like are set. 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 예약녹화 실행이 완료후 다시 소정시간이 경과한 후에 상기와 같은 방법으로 녹화예약을 하려면 예약녹화할 때마다 번거롭게 예약녹화메뉴 화면을 통해 녹화설정을 해야되는 불편함이 있었다Therefore, conventionally, if a reservation is made after the predetermined time has elapsed after the completion of the reservation recording, there is an inconvenience in that the recording setting is cumbersome through the reservation recording menu screen every time recording is scheduled.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, TVCR을 이용하여 예약녹화하는 경우에 일단 예약 설정된 방송 프로그램이 녹화완료된 후 소정시간이 경과한 후에 다시 소정 시간동안 처음과 같은 방식으로 예약 녹화할 수 있도록 함으로써 사용자에게 좀 더 다양하고 편리한 녹화방법을 제공할 수 있도록 한 TVCR의 예약녹화 제어방법을 제공하는데 그 목적이 있다.The present invention is to solve the above problems, in the case of scheduled recording using a TVCR can be scheduled recording in the same manner as the first time again after a predetermined time elapsed after a predetermined broadcast program recording is completed once The purpose of the present invention is to provide a reservation recording control method for a TVCR that can provide a more diverse and convenient recording method to a user.

본 발명의 목적을 달성하기 위한 기술사상으로서, 리모콘에 의해 예약녹화키가 입력되면 예약녹화설정메뉴를 디스플레이시키는 과정과, 상기의 예약녹화설정메뉴에 2차 예약녹화가 설정되면 주기적으로 녹화 시작시간을 확인하여 녹화 끝시간까지 녹화를 실행시키는 과정과, 상기의 녹화실행이 완료되면 소정시간이 경과될 때까지 녹화대기모드로 있다가 이전과 같은 방식으로 다시 소정시간 동안 2차 예약녹화를 실행시키는 과정을 수행하는 발명이 제시된다.As a technical idea for achieving the object of the present invention, a process of displaying a reservation recording setting menu when a reservation recording key is input by a remote controller, and recording start time periodically if a second reservation recording is set in the reservation recording setting menu. The process of executing recording until the end time of recording, and when the above recording execution is completed, enters the recording standby mode until a predetermined time elapses, and then executes the second scheduled recording for a predetermined time again in the same manner as before. An invention is presented which performs the process.

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 원하는 다수개의 방송프로를 예약녹화를 하기 위하여 리모콘(18)의 예약녹화키를 누르면 이에 해당하는 제어코드가 광신호로 변환되어 TVCR의 리모콘 수광부(도면에 미도시)에 인가되고 상기 수광부로부터 이 신호를 인가받은 타이머(17)은 예약녹화키가 입력되었는지 여부를 확인한 후 입력되었다고 확인되면 OSD 처리부(20)를 제어하여 예약녹화 설정메뉴 화면을 CRT부(12)로 디스플레이시키게 된다(S100).First, when the user presses the reserved recording key of the remote controller 18 to reserve the desired number of broadcast programs, the corresponding control code is converted into an optical signal and applied to the remote control receiver (not shown) of the TVCR. The timer 17 receiving this signal from the light receiving unit checks whether or not the reserved recording key is input, and when it is confirmed that the timer is input, the timer 17 controls the OSD processing unit 20 to display the reserved recording setting menu screen on the CRT unit 12 ( S100).

이때, 사용자는 리모콘(18)을 조작하여 상기 예약녹화 설정메뉴 화면에 녹화하고자 하는 방송프로의 녹화채널, 녹화날짜, 시작시간/끝시간, 녹화속도 등을 설정하게 되는데 본 발명에서는 이에 더하며 예약녹화설정 메뉴에 녹화대기 시간란과 2차 녹화시간란을 마련하여 사용자의 선택에 의해 2차 예약녹화를 선택적으로 설정할 수 있게 하고 있다.At this time, the user operates the remote controller 18 to set the recording channel, recording date, start time / end time, recording speed, etc. of the broadcast program to be recorded on the reservation recording setting menu screen. In the recording setting menu, a recording standby time column and a secondary recording time column are provided so that secondary reservation recording can be selectively set by a user's selection.

사용자가 리모콘(18)을 조작하여 상기의 녹화대기 시간란과 2차 녹화시간란에 소정 시간을 설정하면 상기 타이머(17)는 이를 확인한 후 주기적으로 예약녹화 시작시간을 체크하게 된다(S101,S102).If the user sets a predetermined time in the recording standby time column and the secondary recording time column by operating the remote controller 18, the timer 17 checks the scheduled recording start time periodically after checking this (S101, S102).

상기의 체크결과, 녹화시작시간이 도래되면 상기 타이머(17)는 이를 확인한 후 시스콘(19)에 제어신호를 보내고 상기 시스콘(19)이 다시 데크부(16)를 제어하여 녹화를 실행시키게 된다(S103).As a result of the above check, when the recording start time arrives, the timer 17 checks this and sends a control signal to the scissor 19 so that the scissor 19 controls the deck unit 16 to execute recording. (S103).

상기 데크부(16)에 의해 녹화 실행이 계속되다가 설정된 녹화 끝시간이 도래되면 상기 시스콘(19)는 다시 이를 확인한 후 데크부(16)에 제어신호를 보내 녹화대기 모드로 들어가게 된다(S104, S105).When the recording end time is reached while the execution of the recording is continued by the deck unit 16, the sheath cone 19 checks again and sends a control signal to the deck unit 16 to enter the recording standby mode (S104, S105).

이때, 녹화대기 모드 시간은 사용자가 설정한 시간에 의해 결정되며 상기의 설정시간이 경과되면 상기 타이머(17)가 다시 이를 확인한 후 시스콘(19)에 제어신호를 보내면 상기 시스콘(19)은 다시 데크부(16)에 제어신호를 보내 2차 녹화를 실행시키게 된다(S106, S107).At this time, the recording standby mode time is determined by the time set by the user. When the set time has elapsed, the timer 17 checks it again and sends a control signal to the sheath 19. A control signal is sent to the deck unit 16 again to execute secondary recording (S106, S107).

상기의 2차녹화시간 역시 사용자가 설정한 시간으로서 2차 녹화시간이 경과되면 상기 타이머(17)가 이를 확인한 후 마찬가지로 시스콘(19)에 제어신호를 보내고 이에 따라 상기 시스콘(19)은 데크부(16)에 제어신호를 보내 녹화모드를 해제시키게 된다(S108, S109).The secondary recording time is also set by the user, and when the secondary recording time elapses, the timer 17 checks this and then sends a control signal to the sheath 19. Thus, the sheath 19 is decked. A control signal is sent to the unit 16 to cancel the recording mode (S108, S109).

이상의 설명에서 알 수 있는 바와 같이, 본 발명은 사용자가 리모콘(18)을 조작하여 예약녹화키가 입력하면 타이머(17)는 OSD처리부(20)를 제어하여 예약녹화설정메뉴 OSD 화면을 디스플레이시키고 이때, 사용자가 상기의 예약녹화설정메뉴에 2차 예약녹화를 설정하면 상기 타이머(17)에 의해 주기적으로 녹화 시작시간이 확인된 후 녹화 시작시간이 도래되면 상기 타이머(17)의 제어신호를 인가받은 시스콘(19)의 제어에 의해 녹화 끝시간까지 녹화가 실행되고 상기의 녹화실행이 완료되면 소정시간이 경과될 때까지 녹화대기모드로 있다가 이전과 같은 방식으로 다시 소정시간 동안 2차 예약녹화가 실행되게 함으로써 사용자에게 좀 더 다양하고 편리한 녹화방법을 제공할 수 있다.As can be seen from the above description, when the user operates the remote controller 18 and the reservation recording key is input, the timer 17 controls the OSD processing unit 20 to display the reservation recording setting menu OSD screen. When the user sets the second reservation recording in the reservation recording setting menu, the recording start time is periodically checked by the timer 17, and when the recording start time arrives, the control signal of the timer 17 is received. Recording is performed by the control of the sheath 19 until the end time of recording, and when the above recording execution is completed, the recording standby mode is continued until a predetermined time has elapsed. By running the user can provide a more versatile and convenient recording method.
