Abstract

본 발명은 에약녹화모드에 따라 예약녹화기능이 수행되는 경우에 예약녹화의 소요시간이 결과되어도 예약녹화시간의 연장에 대한 정보를 갖는 전송코드데이터가 검출되는 기간만큼 예약녹화동작이 연장될 수 있도록 하는 비디오 테이프레코더의 비상녹화모드에 의한 예약녹화제어장치를 제공한다.According to the present invention, even when the reservation recording function is performed according to the weak recording mode, the reservation recording operation can be extended as long as the transmission code data having information on the extension of the reservation recording time is detected even if the time required for the reservation recording is obtained. A reservation recording control apparatus in an emergency recording mode of a video tape recorder is provided.

그에 따라 본 발명은 소정 채널을 선국하는 튜너(8)와, 선국된 채널의 영상/음성신호를 중간주파증폭하는 영상/음성IF부(10,12), 녹화대상의 방송신호를 녹화가능하게 신호처리하는 녹화신호처리수단(16,18), 상기 녹화대상의 방송신호를 비디오테이프에 기록하는 신호기록부(20), 녹화기능에 따른 비디오테이프의 주행과 상기 신호기록부(20)의 신호기록을 위한 서보구동을 행하는 서보구동수단 (22,24)를 갖춘 비디오테이프레코더에 있어서; 예약녹화모드에 따른 예약채널과 예약날짜 및 예약녹화시간의 기능항목을 설정함과 더불어, 비상녹화 모드의 실행을 키설정하는 기능설정수단(2)과, 상기 설정된 예약녹화모드의 기능항목과 비상녹화모드의 설정데이터를 메모리하는 메모리수단(4),클럭펄스의 발생을 통해 시간을 계시하는 계시수단(6), 예약녹화의 방송신호에 중첩되어 전송되는 비상코드데이터를 검출하는 코드데이터검출수단(26,28,30) 및, 상기 기능설정수단(2)에 의해 설정된 예약녹화모드에 따른 예약녹화기능을 제어함과 더불어, 상기 계시수단(6)에 의해 계시되는 예약녹화시간이 경과되더라도 상기 비상코드데이터가 검출되는 기간만큼 예약녹화기능이 연장되어 지속될 수 있도록 제어하는 제어수단(32)을 구비하여 구성된 것을 특징으로 한다.Accordingly, according to the present invention, a tuner 8 for tuning a predetermined channel, a video / audio IF unit 10, 12 for intermediately amplifying a video / audio signal of a tuned channel, and a broadcast signal for recording can be recorded. Recording signal processing means (16, 18) for processing, a signal recording unit (20) for recording the broadcast signal of the recording object on the video tape, for driving the video tape according to the recording function and for recording the signal of the signal recording unit (20) A video tape recorder having servo drive means (22, 24) for performing servo drive; A function setting means (2) for setting a function of a reservation channel, a reservation date and a reservation recording time according to the reservation recording mode, and keying execution of the emergency recording mode; Memory means 4 for storing the setting data of the recording mode, time means 6 for time-keeping through the generation of clock pulses, and code data detection means for detecting emergency code data superimposed on the broadcast signal of the reservation recording; (26, 28, 30) and the reservation recording function according to the reservation recording mode set by the function setting means (2), and the reservation recording time displayed by the time means (6) has elapsed. And a control means 32 for controlling the reservation recording function to be extended and continued as long as the emergency code data is detected.
