Description

튜너 없는 브이씨알의 예약 녹화 방법Scheduled recording method of VRC without tuner

본 발명은 튜너 없는 브이씨알의 예약 녹화 방법에 관한 것으로, 보다 상세하게는 튜너가 없는 브이씨알에 있어 프로그램의 채널 정보를 텔레비젼으로 전송하고, 텔레비젼의 튜너를 통해 채널 정보에 대응되는 채널의 방송신호를 튜닝하고, 튜닝된 방송신호를 브이씨알로 전송하여 녹화할 수 있도록 하는 튜너 없는 브이씨알의 예약 녹화 방법에 관한 것이다.The present invention relates to a scheduled recording method of a VRC without a tuner, and more particularly, to a TV without a tuner, the channel information of a program is transmitted to a television, and the broadcast signal of a channel corresponding to the channel information is transmitted through the tuner of the TV. And a tuner-less scheduled recording method for transmitting a tuned broadcast signal to a V-Cal so as to enable recording.

일반적으로 브이씨알은 자기 테이프상에 영상 및 음성신호(흑백 및 컬러)를 기록하고, 기록된 영상 및 음성신호를 재생할 수 있도록 한 장치이다. 그리고, 이러한 브이씨알에 있어서, 영상신호의 주파수 대역이 음성신호에 비해 넓으므로, 비디오헤드의 속도는 오디오헤드의 속도보다 높다.In general, VR is a device that records video and audio signals (black and white and color) on a magnetic tape and reproduces the recorded video and audio signals. In this VRC, since the frequency band of the video signal is wider than that of the audio signal, the speed of the video head is higher than that of the audio head.

그러므로, 4개 또는 2개의 헤드를 가지는 헤드드럼이 테이프의 주행 방향과 직각으로 매초 수백 회의 속도로 회전되며, 이때 영상신호가 테이프에 기록된다.Therefore, a head drum having four or two heads is rotated at a speed of several hundred times per second at right angles to the running direction of the tape, at which time the image signal is recorded on the tape.

통상의 브이씨알의 메뉴, 예를 들어 캡션 기능 선택, 예약 녹화 기능 선택, 재생중인 채널, 시간... 기타 등등, 을 선택하고자 할 때, 문자신호로 디스플레이되는 메뉴는 통상 블루 화면에 디스플레이되고, 디스플레이되는 메뉴신호에 따라 사용자는 키패드를 통해 예를 들어 예약 녹화 기능 선택의 경우 예약할 프로그램의 채널, 프로그램의 시작시간 및 끝시간, 예약할 프로그램의 수 기타 등등, 을 선택된다.When you want to select a menu of a normal VR, for example, selecting a caption function, selecting a scheduled recording function, playing channel, time, etc., a menu displayed as a text signal is normally displayed on a blue screen, According to the menu signal displayed, the user selects the channel of the program to be reserved, the start time and end time of the program, the number of programs to be reserved, and the like through the keypad, for example, in the case of the reservation recording function selection.

상기와 같은 종래의 브이씨알의 예약 녹화 기능에 있어, 예약 녹화하고자 하는 프로그램을 수신하는 튜너가 브이씨알에 존재하지 않은 경우 사용자에 의해 선택된 프로그램의 예약 녹화 기능을 실행할 수 없는 문제점이 종종 발생하였다.In the conventional reserved recording function of the conventional VLC, there is often a problem that the reserved recording function of the program selected by the user cannot be executed when the tuner for receiving the program to be reserved recording does not exist in the VRC.

이에 본 발명의 목적은 이와같은 문제점을 해결하기 위한 것으로서, 튜너가 없는 브이씨알에 있어 텔레비젼의 튜너를 이용하여 예약 녹화하고자 하는 방송신호를 녹화할 수 있도록 하는 튜너 없는 브이씨알의 예약 녹화 방법을 제공하고자 하는 것이다.Accordingly, an object of the present invention is to solve such a problem, and provides a tuner-less reservation recording method of a tuner-less VR that can record a broadcast signal to be reserved by using a TV tuner in a TV-less tuner. I would like to.

도 2는 본 발명의 바람직한 실시예에 따른 튜너 없는 브이씨알의 예약 녹화 방법을 나타낸 상세 흐름도이다.2 is a detailed flowchart illustrating a reservation recording method of a tuner without a V-C according to a preferred embodiment of the present invention.

전원을 온한 후 테이프를 삽입하는 초기단계(S1)가 완료되면, 예약녹화모드 선택키가 입력되었는 지를 판단하는 제1판단단계(S2)로 진행되고, 제1판단단계(S2)는 예약녹화모드 선택키가 입력되었는 지를 판단하고, 여기서, 예약녹화모드 선택키가 입력되었다고 판단되면, 예약 녹화할 프로그램의 예약 정보를 표시, 선택 및 저장하는 제1실행단계(S3)로 진행된다.When the initial step S1 of inserting the tape after the power is turned on is completed, the process proceeds to the first judgment step S2 of determining whether the reservation recording mode selection key is input, and the first judgment step S2 is the reservation recording mode. If it is determined that the selection key is input, and if it is determined that the reservation recording mode selection key is input, the process proceeds to the first execution step S3 of displaying, selecting, and storing reservation information of a program to be reserved and recorded.

상기 제1실행단계(S3)는 예약 녹화할 프로그램의 예약 정보를 표시, 선택 및 저장하고, 제1실행단계(S3)의 완료 후 현재 시간과 예약된 시간이 일치하는 지를 판단하는 제2판단단계(S4)로 진행하며, 제2판단단계(S4)는 현재 시간과 예약된 시간이 일치하는 지를 판단한다.The first execution step S3 is a second determination step of displaying, selecting and storing reservation information of a program to be reserved and recording and determining whether the current time and the reserved time match after completion of the first execution step S3. Proceeding to step S4, the second judging step S4 determines whether the current time and the reserved time match.

이 때 제2판단단계(S4)에서 현재 시간이 예약 시간과 일치한다고 판단될 때 브이씨알 및 텔레비젼의 전원을 온한 후 마이컴(12)에 저장된 예약 정보를 아날로그신호로 변환하는 제2실행단계(S5)로 진행되고, 제2실행단계(S5)는 예약 정보를 아날로그신호로 변환하고, 아날로그 신호의 변환이 완료되면, 상기 예약 정보에 대응되는 캐리어를 발생하는 제3실행단계(S6)로 진행된다.At this time, when it is determined that the current time coincides with the reservation time in the second judging step S4, the second execution step S5 of turning on the V-Cal and the TV and converting the reservation information stored in the microcomputer 12 into an analog signal is performed. In the second execution step S5, the reservation information is converted into an analog signal, and when the conversion of the analog signal is completed, the second execution step S5 is performed in the third execution step S6 for generating a carrier corresponding to the reservation information. .

상기 제3실행단계(S6)에서 캐리어가 검출되면, 제2실행단계(S5)에서 변환된 아날로그신호와 발생된 캐리어를 변조하고 변조신호를 텔레비젼으로 전송하는 제4실행단계(S7)로 진행되며, 제4실행단계(S7)는 아날로그신호와 캐리어를 복조한 후 텔레비젼으로 전송하며, 복조신호의 전송이 완료되면, 전송된 변조신호중 캐리어가 있는 지를 판단하는 제3판단단계(S8)로 진행된다.When the carrier is detected in the third execution step S6, the fourth operation step S7 modulates the converted analog signal and the generated carrier in the second execution step S5 and transmits the modulated signal to the television. In operation S7, the analog signal and the carrier are demodulated and then transmitted to the television. When the transmission of the demodulated signal is completed, the third execution step S8 determines whether there is a carrier among the transmitted modulation signals. .

여기서, 캐리어가 있다고 판단되면, 수신된 변조신호를 원래의 신호로 복조하는 제5실행단계(S9)로 진행되고, 제5실행단계(S9)가 완료되면, 복조신호를 디지털 신호로 변환하는 제6실행단계(S10)로 진행되고, 제6실행단계(S10)의 완료후에는 디지털신호로 변환된 예약 정보에 대응되는 채널의 방송신호를 튜닝하는 제7실행단계(S11)로 진행되며, 제7실행단계(S11)는 디지털신호로 변환된 예약 정보에 대응되는 채널의 방송신호를 튜닝한다.Here, if it is determined that there is a carrier, the process proceeds to a fifth execution step S9 of demodulating the received modulated signal into an original signal, and when the fifth execution step S9 is completed, converting the demodulation signal into a digital signal. After the sixth execution step S10 is completed, and the sixth execution step S10 is completed, the seventh execution step S11 is performed to tune the broadcast signal of the channel corresponding to the reservation information converted into the digital signal. In the seventh step S11, the broadcast signal of the channel corresponding to the reservation information converted into the digital signal is tuned.

한편, 제7실행단계(S11)에서 방송신호의 튜닝이 완료되면, 튜닝된 방송신호를 브이씨알로 전송하는 제8실행단계(S12)로 진행되고, 제8실행단계(S12)는 튜닝된 방송신호를 브이씨알로 전송하며, 전송이 완료되면, 전송된 방송신호를 수신하여 녹화하는 제9실행단계(S13)로 진행된다.On the other hand, when the tuning of the broadcast signal is completed in the seventh execution step (S11), the process proceeds to an eighth execution step (S12) for transmitting the tuned broadcast signal to the V-Call, the eighth execution step (S12) is a tuned broadcast When the signal is transmitted to the BC, and the transmission is completed, the process proceeds to a ninth execution step (S13) of receiving and recording the transmitted broadcast signal.

상기 제9실행단계(S13)는 방송신호의 녹화를 하고, 제9실행단계(S13)가 완료되면, 녹화모드가 완료되었는 지를 판단하는 제4판단단계(S14)로 진행되며, 제4판단단계(S14)에서 방송신호의 녹화가 완료되었다고 판단될 때 브이씨알과 텔레비젼의 전원을 오프시키는 제10실행단계(S15)로 진행되며, 제10실행단계(S15)가 완료되면 본 루프를 종료한다. 한편, 제1판단단계(S2)에서 예약모드 선택키가 입력되지 않았다고 판단되면 선택된 타모드를 실행하는 제11실행단계(S16)로 진행되며, 제11실행단계(S11)가 완료되면 본 루프를 종료한다.The ninth execution step (S13) is to record the broadcast signal, and when the ninth execution step (S13) is completed, proceeds to a fourth determination step (S14) for determining whether the recording mode is completed, the fourth determination step When it is determined in step S14 that the recording of the broadcast signal is completed, the process proceeds to the tenth execution step S15 of turning off the V-AL and the TV. When the tenth execution step S15 is completed, the loop ends. On the other hand, if it is determined that the reservation mode selection key is not input in the first determination step (S2), the process proceeds to the eleventh execution step (S16) for executing the selected other mode, and when the eleventh execution step (S11) is completed, the present loop Quit.

이상에서 설명에서와 같이, 본 발명은, 튜너가 없는 브이씨알에 있어, 텔레비젼의 튜너를 통해 예약 녹화를 원하는 프로그램을 튜닝하고 튜닝된 방송신호를 브이씨알을 통해 녹화함으로서, 튜너가 없는 브이씨알이 예약 녹화가 가능한 효과가 있다.As described above, the present invention, in the V-Cal without a tuner, by tuning the program you want to schedule recording through the TV tuner and by recording the tuned broadcast signal through the V-Cal, Scheduled recording is possible.
