Abstract

본 발명은 텔레비디오의 방송모드시 비디오테이프 음성재생제어장치에 관한 것으로, 방송모드시 비디오테이프에 기록된 음성정보의 재생을 위한 키설정을 수행하는 기능설정수단(2)과, 상기 기능설정수단(2)에 의한 방송모드시의 비디오테이프의 음성정보재생을 위한 키설정이 있게 되면 데이터메모리수단(4)의 기능프로그램데이터에 의거하여 테이프로딩검출수단(10)으로부터 비디오테이프의 로딩상태를 검출함에 의해 비디오테이프의 음성신호가 독취되도록 함에 의해, 텔레비전방송의 음성신호와 비디오테이프로부터의 음성신호가 동시에 음성재생가능하도록 제어하는 제어수단(6), 상기 제어수단(6)의 제어하에 방송모드시 비디오테이프의 주행을 위한 구동서보기능을 수행하는 구동서보수단(12,16), 상기 구동서보수단(12,16)에 의해 서보제어되어 비디오테이프의 주행을 위해 구동되는 주행구동수단(14,18), 상기 주행구동수단(14,18)에 의해 주행하는 비디오테이프에 기록된 음성신호를 독취하는 음성독취수단(20,22), 상기 음성독취수단(20,22)에 의해 독취된 음성신호를 재생 가능하게 신호처리하는 음성재생처리수단(24,26), 상기 제어수단(6)의 제어하에 상기 음성처리수단(30,32)을 통한 텔레비전 방송의 음성 신호와 상기 음성재생 처리수단(26)을 통한 비디오테이프로부터의 음성 신호가 음성재생가능하도록 스위칭절환되는 스위칭절환수단(34), 텔레비전방송의 음성신호가 비디오테이프로부터의 음성신호를 각 음성채널별로 할당하여 음성다중처리하는 음성다중처리수단(36,38) 및, 상기 음성다중처리된 각 음성 채널별 음성신호를 음성재생될 수 있도록 매트릭스시키는 매트릭스수단(40)을 구비하여 구성된 것을 특징으로 한다.The present invention relates to a video tape audio playback control apparatus in a broadcast mode of a tele video, comprising: function setting means (2) for performing key setting for reproduction of audio information recorded on a video tape in a broadcast mode; When the key setting for reproducing the sound information of the video tape in the broadcast mode by (2) is made, the loading state of the video tape is detected from the tape loading detecting means 10 on the basis of the function program data of the data memory means 4. Control means (6) for controlling the reproduction of the audio signal of the videotape and the audio signal from the videotape at the same time by allowing the audio signal of the videotape to be read, and the broadcasting mode under the control of the control means (6). Servo-controlled by the drive servo means 12 and 16 and the drive servo means 12 and 16 which perform a drive servo function for driving the video tape. Driving driving means 14 and 18 driven to drive the video tape; audio reading means 20 and 22 reading audio signals recorded on the video tape driven by the driving driving means 14 and 18; The voice processing means (30, 32) under the control of the control means (6) and the voice reproduction processing means (24,26) for signal processing of the voice signal read by the voice reading means (20, 22) to be reproduced. Switching switching means 34 for switching the voice signal of the television broadcast through the voice signal and the video signal through the voice reproduction processing means 26 so as to reproduce the voice, and the voice signal of the television broadcast from the video tape. Voice multiple processing means (36,38) for multiplying voice by assigning the respective voice channels to each voice channel, and matrix means (40) for matrix reproducing the voice signals for each voice multiprocessed voice channel. The generated features.
