Abstract

본 발명은 본 발명은 비디오테이프레코더에서 텔레비전방송신호의 녹화시에 전송코드데이터가 검출되는 영상신호구간에 대응하는 음성신호구간이 무음성녹화될 수 있도록 하는 비디오테이프의 전송데이터 검출에 의한 무음성녹화장치를 제공한다.The present invention provides a non-speech by detecting the transmission data of the video tape so that the audio signal section corresponding to the video signal section in which the transmission code data is detected at the time of recording the television broadcast signal in the video tape recorder can be recorded silently. Provide a recording device.

그에 따라 본 발명은 튜너(4)에 의해 선국되어 영상IF부(6)에 의해 중간주파증폭되고서 녹화신호처리수단(14,16,24,26)에 의해 녹화가능하게 신호처리된 영상신호를 영상기록부(18)가 서보구동부(20,22)의 구동을 통해 비디오테이프에 기록함과 더불어, 음성IF부(8)를 통해 중간주파증폭되어 녹화신호처이된 음성신호가 음성기록부(28)를 통해 비디오테이프에 기록될 수 있는 비디오테이프레코더에 있어서, 음성신호의 무녹화를 위한 무음성녹화모드를 키설정하는 기능설정수단(2)과, 무음성녹화모드의 실행에 따라 상기 음성IF(8)를 통한 음성신호의 공급이 금지되도록 함과 더불어, 상기 영상IF부(6)의 영상신호가 녹화가능하게 공급되도록 모드스위칭되는 모드절환수단(10,12), 상기 선국되는 방송신호에서 무음성녹화에 대한 정보를 갖는 전송코드데이터를 검출하는 코드데이터검출수단(30), 무음성녹화모드의 실행시에 상기 음성IF부(8)의 음성신호를 뮤트시키기 위한 신호뮤트수단(32) 및, 상기 기능설정수단(2)에 의한 무음성녹화모드의 설정시에 상기 코드데이터걸출수단 (30)으로부터 전송코드데이터가 검출되는 영상구간에 대응하는 음성신호에 대해서 무음성녹화되도록 상기 모드절환수단(10,12)을 스위칭제어함과 더불어, 상기 신호뮤트수단(8)을 통한 음성뮤트가 가능하도록 제어하는 제어수단(34)을 구비하여 구성된 것을 특징으로 한다.Accordingly, the present invention selects an image signal tuned by the tuner 4, amplified by the image IF unit 6, and signal-processed by the recording signal processing means 14, 16, 24, 26. The video recording unit 18 records on the video tape by driving the servo drivers 20 and 22, and the audio signal, which is amplified by the intermediate frequency through the audio IF unit 8 and becomes the recording signal destination, through the audio recording unit 28. A video tape recorder capable of being recorded on a video tape, comprising: function setting means (2) for key setting an unvoiced recording mode for non-recording of an audio signal, and said voice IF (8) in accordance with execution of the unvoiced recording mode; The mode switching means 10 and 12 are mode-switched so that the supply of the audio signal through the video signal is prohibited and the video signal of the video IF unit 6 is recordable. The audio signal is recorded from the broadcast signal. Detect transmission code data with information on The code data detecting means 30, the signal muting means 32 for muting the audio signal of the voice IF section 8 at the time of executing the silent recording mode, and the unvoiced sound by the function setting means 2 When the recording mode is set, the mode switching means 10 and 12 are switched and controlled so as to be silently recorded for the audio signal corresponding to the video section in which the transmission code data is detected from the code data output means 30. It is characterized in that it comprises a control means 34 for controlling the voice mute through the signal mute means (8).

Claims

An image recording unit 18 that is tuned by the tuner 4 and amplified by an intermediate frequency by the image IF unit 6, and then signal-processed by the recording signal processing means 14, 16, 24, and 26 to be recordable. The audio signal is recorded on the video tape by driving the servo drive units 20 and 22, and the audio signal, which is amplified by the intermediate frequency through the audio IF unit 8 and becomes the recording signal destination, is recorded on the video tape through the audio recording unit 28. A video tape recorder, comprising: function setting means (2) for key setting an unvoiced recording mode for non-recording of an audio signal, and an audio signal through the voice IF (8) in accordance with the execution of the unvoiced recording mode. In addition to prohibiting the supply, the mode switching means 10 and 12 are mode-switched so that the video signal of the video IF unit 6 can be supplied for recording, and has information on the unvoiced recording in the selected broadcast signal. Code data inspection to detect transmission code data Setting of the silent recording mode by the means 30, the signal muting means 32 for muting the audio signal of the speech IF section 8 at the time of executing the silent recording mode, and the function setting means 2 And switching the mode switching means 10 and 12 so as to be silently recorded for the audio signal corresponding to the video section in which the transmission code data is detected from the code data sending means 30 at the same time.
