Abstract

본 발명은 텔레비디오의 A/V모드제어장치에 관한 것으로, TV기능과, VCR기능을 선택하기 위한 채널업/다운버튼(10b)을 갖춘 제어신호입력부(10)와, 전원ON시 또는 상기 채널업/다운버튼(10b)에 의한 A/V모드의 설정을 제어하는 제어부(12), 그 제어부(12)의 제어하에 전원ON시 A/V모드의 설정을 안내하는 화면표시를 위한 OSD신호를 생성하는 OSD처리부(14), 상기 전원ON시 비디오테이프(T)의 장착을 검출하는 테이프장착검출부(34), 상기 전원ON시 상기 테이프장착검출부(34)의 테이프장착 검출신호를 기초로 상기 제어부(12)에 대한 비디오채널로의 절환을 지정하는 신호를 생성하는 채널절환제어신호생성부(36)을 갖추어 구성되고, 상기 제어부(12)는 상기 A/V모드의 선택상태에서 상기 비디오테이프(T)의 장착에 기초하는 상기 채널절환제어신호에 의거하여 비디오 채널의 선국을 실행하도록 된 것이다.The present invention relates to an A / V mode control apparatus for tele video, comprising a control signal input unit (10) having a TV function and a channel up / down button (10b) for selecting a VCR function, when the power is ON or the channel. A control unit 12 for controlling the setting of the A / V mode by the up / down button 10b, and an OSD signal for displaying a screen for guiding setting of the A / V mode when the power is turned on under the control of the control unit 12. The control unit based on the generated OSD processing unit 14, a tape mounting detection unit 34 for detecting mounting of the video tape T when the power is turned on, and a tape mounting detection signal of the tape mounting detection unit 34 when the power is turned on. And a channel switching control signal generation section 36 for generating a signal for designating a switching to the video channel for reference (12), wherein the control section (12) includes the video tape (in the selected state of the A / V mode). Based on the channel switching control signal based on the mounting of T). It is to perform the tuning.

Claims

In a TVCR having a TV function for reproducing a broadcast video / audio signal and a VCR function for recording / playing back a video tape (T), a channel up / down button for selecting the TV function and the VCR function ( A control signal input means 10 having a 10b), a control means 12 for controlling the setting of the A / V mode when the power is turned ON or by the channel up / down button 10b, and the control means 12 OSD processing means (14) for generating an OSD signal for displaying a screen for guiding setting of the A / V mode under power on under control, and tape mounting detecting means (34) for detecting mounting of the video tape (T) at power on. Channel switching control signal generating means (36) for generating a signal specifying switching to the video channel for the control means (12) based on the tape mounting detection signal of the tape mounting detection means (34) when the power is turned on. And the control means 12 are selected in the A / V mode. And the channel selection control signal based on the mounting of the video tape (T) to tune the video channel.

2. The channel switching control signal generating means (36) according to claim 1, characterized in that the channel switching control signal generating means (36) includes an inverter (46) for inverting the tape mount detection signal, a tape mount detection signal inverted by the inverter (46), and the power on state. And an AND gate for generating a control signal for controlling switching to a video channel by performing a logical AND processing of the power ON control signal of the control means (12).

※ Note: This is to be disclosed based on the first application.
