Abstract

본 발명은 예약녹화시간대가 상호 중첩되는 복수개의 방송채널을 복수개의 선국수단을 이용하여 순환적으로 선국하면서 단일의 정보기록매체에 주/부화면용 신호로써 녹화시킬 수 있도록 한 복수채널 예약녹화제어장치를 제공하기 위한 것이다.The present invention provides a multi-channel reservation recording control that allows a plurality of broadcast channels in which reservation recording time zones overlap each other to be recorded as a main / sub picture signal on a single information recording medium while being cyclically tuned using a plurality of tuning means. It is for providing a device.

이를 위해 본 발명은, 방송신호 선국용 복수튜너와 그 복수튜너에 의한 방송신호의 영상/음성 신호를 처리하는 영상/음성처리수단을 포함하는 텔레비젼기능과 그 영상/음성처리수단으로부터의 영상/음성신호를 비디오테이프에 기록시키거나 그 기록된 영상/음성신호를 재생시키는 비디오테이프레코더기능이 혼재된 A/V기기에 있어서, AV스위칭부(16)를 매개로 인가되는 상기 복수튜너로부터의 IF신호를 기록 가능한 영상/음성신호로 처리하는 복수의 기록신호처리부(18A,18B)를 갖춘 기록신호처리수단(18)과, 상기 복수의 기록신호처리부(18A,18B)로부터의 신호를 상호 차등적으로 증폭시켜 기록동작을 수행하는 신호기록부(22)로 인가하는 복수의 기록신호증폭부(20A,20B)를 갖춘 기록신호증폭수단(20) 및, 예약된 복수개의 녹화정보를 기초로 해당 채널을 순차적으로 선국시키고 신호처리된 각 채널의 영상/음성신호가 단일의 비디오테이프(24)상에 기록깊이를 달리하면서 주/부화면용 신호로 기록되도록 제어하는 제어부(28)를 포함하여 구성되고, 상기 신호기록부(22)에는 상기 복수의 기록신호증폭부(20A,20B)에 대응되는 복수의 기록헤드가 갖추어진다.To this end, the present invention provides a television function comprising a plurality of tuners for broadcast signal selection and a video / audio processing means for processing a video / audio signal of a broadcast signal by the plurality of tuners and a video / audio from the video / audio processing means. In an A / V apparatus having a mixed video tape recorder function for recording a signal on a video tape or reproducing the recorded video / audio signal, an IF signal from the plurality of tuners applied through the AV switching unit 16. Recording signal processing means 18 having a plurality of recording signal processing units 18A and 18B for processing a video / audio signal into a recordable image, and signals from the plurality of recording signal processing units 18A and 18B. Recording signal amplifying means (20) having a plurality of recording signal amplifying parts (20A, 20B) to be amplified and applied to the signal recording part (22) for performing a recording operation, and the corresponding channels are sequentially made based on the plurality of reserved recording information. And a control unit 28 for controlling the video / audio signal of each channel which has been tuned to and processed as a signal for main / sub picture while varying the recording depth on a single video tape 24. The signal recording section 22 is provided with a plurality of recording heads corresponding to the plurality of recording signal amplifiers 20A and 20B.
