Abstract

A digital tuner including an antenna is provided to use a chassis and a cover of the main body of the digital tuner as an antenna to simplify a tuner circuit configuration and reduce the manufacturing cost. A digital tuner(100) includes a low noise amplifier(200) located before the digital tuner, and an antenna. The antenna receives a broadcasting signal through a chassis and a cover constructing the body of the digital tuner, amplifies the received broadcasting signal through the low noise amplifier, and applies the amplified broadcasting signal to the digital tuner.

Description

안테나를 내장한 디지털 튜너{Digital Tuner having an antenna therein}Digital Tuner having an antenna therein

도 1은 종래의 튜너를 보여주는 블록도이다.1 is a block diagram showing a conventional tuner.

도 2는 본 발명에 따른 디지털 튜너를 보여주는 블록도이다.2 is a block diagram showing a digital tuner according to the present invention.

본 발명은 안테나를 내장한 디지털 튜너에 관한 것이다.The present invention relates to a digital tuner incorporating an antenna.

도 1에 도시된 바와 같이, 일반적으로 공중파 방송신호를 수신하기 위하여 옥내외 안테나(20)를 튜너(10)에 연결하여 원하는 방송신호를 수신한다.As shown in FIG. 1, in order to receive an over-the-air broadcast signal, an indoor and outdoor antenna 20 is connected to the tuner 10 to receive a desired broadcast signal.

한편, 디지털 튜너에 있어서는 튜너 전단에 고감도 안테나 모듈이나 안테나 회로를 내장하여 옥내외 안테나를 통하지 않고 방송신호를 수신한다.On the other hand, in a digital tuner, a high sensitivity antenna module or an antenna circuit is built in front of the tuner to receive a broadcast signal without going through an indoor or outdoor antenna.

그러나, 이를 위해서는 상기한 바와 같이, 고감도 안테나 모듈이나 안테나 회로를 내장할 필요가 있으며, 이에 따라 회로가 복잡해지고 제조원가가 상승한다는 문제점이 있다.However, for this purpose, as described above, it is necessary to embed a high-sensitivity antenna module or an antenna circuit, and thus there is a problem that the circuit becomes complicated and the manufacturing cost increases.

따라서, 본 발명은 이와 같은 문제점을 해결하기 위하여 제시되는 것으로, 본 발명의 목적은 간단한 구성으로 안테나를 내장할 수 있는 디지털 튜너를 제공하는 것이다.Accordingly, the present invention has been presented to solve such a problem, and an object of the present invention is to provide a digital tuner capable of embedding an antenna in a simple configuration.

본 발명의 다른 목적과 특징 및 이점은 이하에 설명되는 실시예로부터 보다 명확하게 이해될 것이다.Other objects, features and advantages of the present invention will be more clearly understood from the embodiments described below.

본 발명에 따르면, 디지털 튜너에 있어서, 저잡음 증폭기를 튜너의 전단에 설치하고, 튜너를 구성하는 샤시와 커버를 통하여 방송신호를 수신하여 저잡음 증폭기를 통하여 증폭하고, 증폭된 방송신호를 튜너에 인가하는 안테나를 내장한 디지털 튜너가 개시된다.According to the present invention, in a digital tuner, a low noise amplifier is provided in front of a tuner, receives a broadcast signal through a chassis and a cover constituting the tuner, amplifies through a low noise amplifier, and applies the amplified broadcast signal to the tuner. Disclosed is a digital tuner incorporating an antenna.

이하, 첨부된 도면을 참조하여 본 발명의 일 실시예를 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

도 2는 본 발명에 따른 디지털 튜너를 보여주는 블록도이다.2 is a block diagram showing a digital tuner according to the present invention.

도시된 바와 같이, 디지털 튜너(100)의 전단에는 저잡음 증폭기(Low Noise Amp; 200)이 설치된다.As shown, a low noise amplifier 200 is installed at the front end of the digital tuner 100.

디지털 튜너(100)의 본체는 샤시와 커버로 구성되며, 본 발명에 따르면, 본체의 샤시와 커버는 방송신호를 수신하는 안테나의 역할을 한다.The main body of the digital tuner 100 includes a chassis and a cover. According to the present invention, the chassis and the cover of the main body serve as an antenna for receiving a broadcast signal.

이와 같은 구성에 의하면, 디지털 본체(100)의 샤시와 커버는 안테나로서의 역할을 수행하여 공중파 방송신호를 수신한다.According to such a configuration, the chassis and the cover of the digital main body 100 serve as an antenna to receive an over-the-air broadcast signal.

그러나, 디지털 튜너(100) 본체의 샤시와 커버를 통하여 수신된 방송신호는 상당히 미약하기 때문에 수신된 방송신호를 저잡음 증폭기(200)에 인가하여 적정한 수준으로 증폭한다.However, since the broadcast signal received through the chassis and cover of the digital tuner 100 main body is very weak, the received broadcast signal is applied to the low noise amplifier 200 and amplified to an appropriate level.

이어, 저잡음 증폭기(200)에서 증폭된 방송신호는 다시 디지털 튜너(100)에 인가되어 원하는 방송신호를 수신하게 된다.Subsequently, the broadcast signal amplified by the low noise amplifier 200 is applied to the digital tuner 100 again to receive a desired broadcast signal.

이와 같이, 별도의 고감도 안테나 모듈이나 안테나 회로를 내장하지 않음으로써 튜너의 회로가 간단해지고, 제조원가가 줄어드는 이점이 있다.As described above, the circuit of the tuner is simplified and the manufacturing cost is reduced by not embedding a separate high-sensitivity antenna module or antenna circuit.

또한, 미약한 방송신호를 저잡음 증폭기를 통하여 충분히 증폭함으로써 수신감도를 향상시킬 수 있다.In addition, reception sensitivity can be improved by sufficiently amplifying a weak broadcast signal through a low noise amplifier.

이상에서는 본 발명의 바람직한 실시예를 중심으로 설명하였지만, 당업자의 수준에서 다양한 변경과 변형을 가할 수 있다. 따라서, 본 발명의 범위는 상기한 실시예에 한정되어 해석되어서는 안되며, 이하에 기재된 청구범위에 근거하여 해석되어야 한다.Although the above has been described with reference to the preferred embodiment of the present invention, various changes and modifications can be made at the level of those skilled in the art. Therefore, the scope of the present invention should not be interpreted as being limited to the above embodiments, but should be interpreted based on the claims described below.

이상에서 설명한 바와 같이, 본 발명에 따르면 디지털 튜너 본체의 샤시와 커버를 안테나로 기능하도록 함으로써 별도의 고감도 안테나 모듈이나 안테나 회로를 내장할 필요가 없어 튜너의 회로가 간단해지고, 제조원가가 줄어드는 이점이 있다.As described above, according to the present invention, the chassis and cover of the digital tuner function as antennas, thereby eliminating the need to incorporate a separate high-sensitivity antenna module or antenna circuit, thereby simplifying the tuner circuit and reducing manufacturing costs. .

또한, 미약한 방송신호를 저잡음 증폭기를 통하여 충분히 증폭함으로써 수신감도를 향상시킬 수 있다.In addition, reception sensitivity can be improved by sufficiently amplifying a weak broadcast signal through a low noise amplifier.
