본 발명은 음성다중방송에 적응하기 위한 음성다중컨버터시스템에 관한 것으로, 특히 신호스위칭회로를 통해서 안테나 신호를 분배, 통과 또는 절연시킴으로써 튜너로부터 직접 RF신호로 변환시켜 기존의 텔레비젼에 적용할 수 있도록 된 음성다중컨버터시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice multiple converter system for adapting to voice multiple broadcasting. In particular, the antenna signal is distributed, passed, or isolated through a signal switching circuit to be converted into an RF signal directly from a tuner and applied to an existing television. The present invention relates to a voice multiple converter system.

음성다중방송은 텔레비젼방송국에서 2가지 음성을 동시에 전송하고 수신측에서 2가지 음성신호를 각각 분리하여 청취할 수 있도록하는 방송시스템으로서, 자국어와 외국어를 동시에 전송, 수신하거나 스테레오 방송을 실시함으로서 텔레비젼 프로그램의 국제교환이나 외국어교육, 원음의 재현 및 보다나은 음향효과를 증진시킬 수 있도록 된 것인데, 그 전송방식으로는 2개의 음성반송파를 사용하여 전송시키는 방식과 부 반송파를 써서 제2의 음송을 반송하여 전송시키는 방식등이 사용되고 있다.Voice multiple broadcasting is a broadcasting system that transmits two voices at the same time and listens to two voice signals separately at the receiving side. International exchange, foreign language education, reproduction of original sound, and better sound effect can be promoted. As the transmission method, two voice carriers are used to transmit and second carriers are sent using subcarriers. The transmission method is used.

그런데 음성다중방송에 대한 대비가 되어 있지 않은 텔레비젼(이하 기존의 텔레지젼이라함)에 있어서는, 음성다중방송을 수신하여 2가지음성을 재생시킬 수 있도록 구성되어 있지 않으므로 음성다중시스템의 여러 기능을 이용할 수 없었기 때문에 음성다중시스템을 이용하기 위해서는 별도의 변환장치를 내장하여 신호를 처리해야만 하였다.However, TVs that are not prepared for voice multicasting (hereinafter referred to as conventional telegrams) are not configured to receive two voices and reproduce two voices, so that various functions of the voice multiplexing system can be used. In order to use the voice multiplexing system, a separate converter was required to process the signal.

한편 종래에 개발되었던 음성다중컨버터로서, 안테나로부터 신호를 받아들여 튜너를 통해 영상반송파와 음성반송파로 분리한 다음, 음성반송파는 음성회로를 통해 출력시켜주고 이어 영상반송파를 영상중간 주파회로와 영상검파회로를 거치게 하여 영상신호를 얻어낸다음 RF컨버터를 통해 변환시켜서 기존의 텔레비젼에 전달하는 시스템을 사용하고 있었는데, 이와같은 종래의 음성다중컨버터는 영상반송파를 증폭하거나 검파하여 RF컨버터를 통해 RF신호로 변환시켜주어야 하는바, 즉 안테나부터 수신된 IF신호로, 이 IF신호를 다시 RF신호로 변환시켜주어야 하므로 불필요한 신호손실과 전력소모를 가져올 뿐만 아니라, 다른 영상매개체, 즉 모니터나 오디오, 비데오 선택용 A/V텔레비젼, 또는 VTR등을 동시에 이용할 수가 없고, 동시에 이용하고자 할때에는 별도의 컨버터를 설치하여야 하는 등의 문제점이 있었다.On the other hand, as a conventionally developed voice multiple converter, it receives a signal from an antenna and separates it into an image carrier and a voice carrier through a tuner, and then outputs the voice carrier through an audio circuit, and then the image carrier is output through an intermediate video circuit and image detection The system uses a system that obtains a video signal through a circuit and converts it through an RF converter and transmits it to a conventional television. Such a conventional voice multiple converter converts an image carrier into an RF signal by amplifying or detecting a video carrier. In other words, the IF signal received from the antenna, the IF signal must be converted back to the RF signal, which not only leads to unnecessary signal loss and power consumption, but also to other video media such as monitor, audio, and video A. You cannot use / VTV or VTR at the same time. There was a problem such as need to install a separate converter.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위해서 신호스위칭회로를 설치함으로써 튜너로부터 영상반송파를 직접 받아들려 RF신호로 변환하여 기존의 텔레비젼에 전달할 수 있도록 함으로써 신호의 손실이나 불필요한 전력소모를 줄이는 한편, 중간 주파수분배기를 통해 영상신호를 모니터나 A/V텔레비젼에 연결할 수 있도록 함으로써 기존의 텔레비젼으로 음성다중방송을 수신할 수 있을 뿐만 아니라 모니터나 A/V텔레비젼을 동시에 사용할 수 있으며, 동시에 VTR을 통해 다른방송을 녹화할 수 있도록 된 음성다중컨버터시스템을 제공하는데 그 목적이 있다.Accordingly, in order to solve the above problems, the present invention provides a signal switching circuit to directly receive an image carrier from a tuner, convert it into an RF signal, and transmit the signal to an existing television, thereby reducing signal loss and unnecessary power consumption. By connecting the video signal to a monitor or A / V TV through an intermediate frequency divider, you can not only receive audio multiple broadcasts on existing TVs, but also use the monitor or A / V TV simultaneously. It is an object of the present invention to provide a voice multiple converter system capable of recording a broadcast.

이하 본 발명의 구성 및 작용효과를 예시된 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the illustrated drawings.

본 발명은 안테나(1)의 출력단에 분배기(2)가 연결되어, 방송파신호가 분배기(2)를 통해 튜너(3)와 신호스위칭회로(4)에 각각 인가되고, 상기 튜너(3)는 IF분배기(5)를 통해 영상중간주파회로(6)와 제1 및 제2음성회로(7)(8) 및 RF컨버터(9)에 연결되며, 상기 영상중간주파회로(6)는 자동이득제어회로(10)를 통해 튜너(3)에 연결되는 한편 영상검파회로(11)에 연결되어, 이 영상검파회로(11)에서 검파된 영상신호가 모니터나 A/V텔레비젼으로 출력되고, 제1 및 제2음성회로(7)(8)을 통한 신호는 제1 및 제2스피커로, RF컨버터(9)를 통한 신호는 기존의 텔레비젼으로 각각 출력되는 구조로 되어 있다.In the present invention, the splitter 2 is connected to the output terminal of the antenna 1 so that a broadcast wave signal is applied to the tuner 3 and the signal switching circuit 4 through the splitter 2, respectively. It is connected to the image intermediate frequency circuit 6, the first and second audio circuits 7 and 8 and the RF converter 9 through an IF divider 5, and the image intermediate frequency circuit 6 controls the automatic gain. It is connected to the tuner 3 through the circuit 10 and to the image detection circuit 11 so that the image signal detected by the image detection circuit 11 is output to a monitor or A / V television. The signals through the second audio circuits 7 and 8 are output to the first and second speakers, and the signals through the RF converter 9 are output to conventional televisions, respectively.

상기와 같은 구조를 갖는 본 발명은 신호스위칭회로(4)를 통해 안테나(1)로부터의 신호를 분배, 통과 또는 절연시켜주고 튜너로부터 중간주파수(IF)신호를 직접 RF신호로 변환시킴으로써 모니터나 A/V텔레비젼으로 시철할 수 있음은 물론 기존의 텔레비젼으로도 시청할 수 있도록 된 것이다.According to the present invention having the above structure, the signal switching circuit 4 distributes, passes or insulates the signal from the antenna 1, and converts the intermediate frequency (IF) signal directly to the RF signal from the tuner. It can be installed on / V TV and can be viewed on existing TVs.

본 발명의 작용을 도면으로 통해 좀더 상세히 설명하면, 제1도는 본 발명에 따른 음성다중컨버터의 블럭다이어그램으로서, 안테나(1)로부터 수신되는 신호는 분배기(2)를 통해 튜너(3)와 신호스위칭회로(4)는 스위칭신호전압을 인가 또는 차단시켜 줌으로써 RF컨버터(9)의 동작을 턴온시키거나 턴오프시켜 주게되며, 기존의 텔레비젼으로 RF신호를 출력시키게 된다.Referring to the operation of the present invention in more detail with reference to the drawings, Figure 1 is a block diagram of a voice multiple converter according to the present invention, the signal received from the antenna (1) through the divider (2) and the signal switching signal The circuit 4 turns on or off the operation of the RF converter 9 by applying or blocking a switching signal voltage, and outputs an RF signal to a conventional television.

이때 신호스위칭회로(4)는 분배기(2)를 통해 안테나 신호를 분배받아 직접 기존의 텔레비젼에 연결하도록 하여 일반 텔레비젼의 방송국선국과 같이 챈널을 선택하면서 수신할 수 있도록 하거나, 튜너(3)를 통한 IF신호를 IF분배기(5)를 통해 분배받아 RF컨버터(9)에서 3/4챈널에 맞는 R/F신호로 변환한 다음 기존의 텔레비젼에 전달할 수 있도록 함으로써 변환기의 튜너(3)로 챈널을 선택할 수 있도록 하는데, 위의 경우에서 제1음성회로(7)와 제2음성회로(8)는 항상 동작되어 짐으로써 제1스피커와 제2스피커를 통해 음성신호를 재생시키게 된다.At this time, the signal switching circuit 4 receives the antenna signal through the splitter 2 and connects the antenna signal directly to an existing television so that it can be received while selecting a channel like a broadcasting station of a general television, or through a tuner 3. The IF signal is distributed through the IF divider (5), and the RF converter (9) converts the R / F signal for the 3/4 channel and transmits it to the existing TV so that the channel can be selected by the tuner (3) of the converter. In the above case, the first voice circuit 7 and the second voice circuit 8 are always operated to reproduce the voice signal through the first speaker and the second speaker.

한편 IF분배기(5)를 통한 영상반송파는 영상중간주파회로(6)와 영상검파회로(11)를 통해 영상신호로 바뀌어 모니터나 A/V텔레비젼에 인가됨으로써 영상을 재생시킬 수 있도록 되는데, 이러한 동작은 RF컨버터(9)의 동작과 동시에 이루어질 수 있으므로 기존의 텔레비젼으로 방송을 수신하면서 모니터나 A/V텔레비젼을 이용할 수 있으며, VTR을 이용할 경우에는 모니터나 A/V텔레비젼과 다른 챈널의 방송을 수신녹화 할 수도 있게 된다.On the other hand, the image carrier through the IF divider 5 is converted into the image signal through the image intermediate frequency circuit 6 and the image detection circuit 11 to be applied to the monitor or A / V television to reproduce the image. Can be performed at the same time as the operation of the RF converter (9), so that you can use a monitor or A / V television while receiving broadcasts on an existing television, and when using a VTR, it can receive broadcasts from a monitor or A / V television and other channels. You can also record.

제2도는 종래의 음성다중컨버터의 블럭다이어그램으로, 안테나(1)로부터 수신된 신호가 튜너를 통해 분배기(5)에 인가되고, 이는 다시 음성반송파와 영상반송파로 나뉘어지면서 음성반송파는 제1음성회로(7)와 제2음성회로(8)를 통해 음성신호로 재생되고 영상반송파는 영상중간주파회로(6)와 영상검파회로(11)를 거친다음 자동이득제어회로(10)를 통해 튜너(3)로 연결되거나 RF컨버터(9)에서 RF신호로 변환된 다음 기존의 텔레비젼에 인가되는 구조로 되어 있다.2 is a block diagram of a conventional voice multiple converter, in which a signal received from an antenna 1 is applied to a splitter 5 through a tuner, which is divided into a voice carrier and an image carrier, and the voice carrier is a first voice circuit. (7) and the second audio circuit (8) is reproduced as an audio signal, and the image carrier passes through the image intermediate frequency circuit (6) and the image detection circuit (11), and then through the automatic gain control circuit (10) the tuner (3). ) Is converted into an RF signal in the RF converter 9 and then applied to an existing television.

이와같이 종래의 음성다중컨버터는 안테나로부터 수신된 방송파신호는 IF신호로, 이 IF신호는 다시 RF컨버터(9)를 통해 RF신호로 변환되어 기존의 텔레비젼에 인가되는 구조로 되어 있어 신호의 손실이나 불필요한 전력소모가 생기게 되며, 또한 모니터나 A/V텔레비젼과 같은 영상매개체와 동시에 이용할 수 없는 불편이 있다.In the conventional voice multiple converter, the broadcast wave signal received from the antenna is an IF signal, and the IF signal is converted into an RF signal through the RF converter 9 and applied to an existing television. Unnecessary power consumption is generated, and there is a inconvenience that can not be used at the same time with a video medium such as a monitor or A / V TV.

그러나 본 발명은 신호스위칭회로(4)의 기능을 통해 종래의 여러가지 문제점이나 불편을 해소하고, 안테나 신호를 직접 RF컨버터(9)를 통해 기존의 텔레비젼에 인가하거나 각종 영상매개체를 동시에 이용할 수 있도록 함으로서, 신호의 손실이나 불필요한 전력의 손실을 방지할 수 있고, VTR을 통해서 시청중인 챈널외의 프로그램도 녹화할 수 있는 효과가 있다.However, the present invention solves various problems and inconveniences in the related art through the function of the signal switching circuit 4, and by directly applying an antenna signal to an existing television through the RF converter 9 or using various image media simultaneously. In addition, it is possible to prevent signal loss or unnecessary power loss, and to record programs other than the channel being watched through the VTR.
