디지털 영상 압축 및 디지털 변복조와 같은 디지털 기술이 급속히 발전함에 따라 디지털 방송에 대한 표준화 및 상용화가 급속히 발전되고 있다. 디지털 방송을 수신하는 셋톱박스(STB)와 같은 디지털 방송수신기는 사용자가 선택한 방송 프로그램을 수신기 내에 구비된 디코더를 이용하여 원래의 A/V(Audio/Video) 데이터로 복원한 후 일반 텔레비전과 같은 A/V 출력장치로 전송하여, 사용자로 하여금 선택적으로 방송 프로그램을 시청할 수 있도록 해주고 있다.With the rapid development of digital technologies such as digital image compression and digital modulation and demodulation, the standardization and commercialization of digital broadcasting is rapidly developing. A digital broadcast receiver such as a set-top box (STB) that receives digital broadcasts restores the broadcast program selected by the user to original A / V (Audio / Video) data using a decoder provided in the receiver, and then A / V output to the device, allowing the user to selectively watch the broadcast program.

최근에는 대부분의 가정에서 안방, 거실, 공부방 등과 같은 여러 장소에 각각 한 대씩의 텔레비전이 설치되어 있는데, 이러한 여러 대의 텔레비전을 단일 셋톱박스에 접속시키는 경우에는 각각의 텔레비전을 통해 위성방송, 케이블방송, 디지털 지상파방송 등을 시청할 수 있다.Recently, most homes have one television set in various places such as a home room, a living room, a study room, and the like. When the multiple TVs are connected to a single set-top box, each television is provided with a satellite, cable, You can watch digital terrestrial broadcasting.

그러나, 종래에는 셋톱박스에서 각 방까지의 무손실 신호전송이 어려울 뿐만 아니라, 선로공사 등을 통해 추가적인 선로시공이 선행되어야 하므로 설치비용의 증대 및 설치과정이 어렵다는 문제점이 있다.However, in the related art, lossless signal transmission from the set top box to each room is difficult, and additional line construction must be preceded by line construction, etc., thereby increasing the installation cost and making the installation process difficult.

본 발명의 목적은 단일 셋톱박스에서 원격지까지의 무손실 신호전송 및 추가적인 선로시공 없이 기 설치된 네트워크를 통해 단일 셋톱박스와 다른 장소에 설치된 원격지의 TV 수신기를 접속시키고, RF 리모컨 송수신기를 통해 셋톱박스가 설치되어 있지 않은 원격지의 다른 장소에서도 셋톱박스의 원격제어가 가능하도록 해주는 기술을 제공하는 것이다.An object of the present invention is to connect a single set-top box and a remote TV receiver installed in another place through a network installed without lossless signal transmission and additional line construction from a single set-top box to a remote site, and the set-top box is installed through an RF remote transceiver It is to provide a technology that enables the remote control of the set-top box in other places that are not remote.

Set the broadcast channel.

이때, 방송신호 수신부(321)로부터 설정된 방송채널의 디지털 방송신호를 입력받은 엠펙 디코딩 처리부(322)는 방송신호를 디코딩 처리하고 D/A 변환한다.At this time, the MPEG decoding processor 322, which receives the digital broadcast signal of the broadcast channel set by the broadcast signal receiver 321, decodes the broadcast signal and performs D / A conversion.

이어서, 방송신호 변조부(323)는 엠펙 디코딩 처리부(322)로부터 방송신호를 입력받아 소정의 방송용 주파수로 변조한 후 증폭기(324)로 출력한다.Subsequently, the broadcast signal modulator 323 receives a broadcast signal from the MPEG decoding processor 322, modulates the broadcast signal to a predetermined broadcast frequency, and outputs the broadcast signal to the amplifier 324.

방송신호 변조부(323)는 소정의 방송용 주파수로 변조한 원격방송신호를 네트워크(10)로 직접 출력할 수도 있다.The broadcast signal modulator 323 may directly output the remote broadcast signal modulated at a predetermined broadcast frequency to the network 10.

방송신호 변조부(323)에서 출력되는 원격방송신호는 특정의 방송용 채널 주파수로 설정될 수 있으며, 방송용 채널 주파수를 회피한 중간주파수로 설정될 수도 있다.The remote broadcast signal output from the broadcast signal modulator 323 may be set to a specific broadcast channel frequency or may be set to an intermediate frequency avoiding the broadcast channel frequency.

원격방송신호가 중간주파수로 설정될 경우, 도 3에 도시된 바와 같이 원격지의 서브 TV 수신기(20) 측 네트워크(10)에는 중간주파수 신호를 특정의 방송용 채널 주파수로 재변조 출력하는 변조부(330)를 더 포함한다.If the remote broadcast signal is set to the intermediate frequency, as shown in Figure 3, the sub-TV receiver 20 side of the network 10, the modulation unit 330 for remodulating and outputting the intermediate frequency signal to a specific broadcast channel frequency More).

증폭기(324)는 방송신호 변조부(323)로부터 입력받은 소정의 방송용 주파수로 변조된 원격방송신호를 증폭하여 네트워크(10)로 출력한다.The amplifier 324 amplifies the remote broadcast signal modulated at a predetermined broadcast frequency received from the broadcast signal modulator 323 and outputs the amplified remote broadcast signal to the network 10.

그러면, 서브 TV 수신기(20)는 네트워크(10)를 통해 원격방송신호를 입력받고, 그에 따른 해당 프로그램의 방송을 사용자에게 디스플레이한다.Then, the sub-TV receiver 20 receives the remote broadcast signal through the network 10 and displays the broadcast of the corresponding program to the user.

[원격지 #1]에 있는 메인 TV 수신기(30)는 사용자의 입력 조작에 따라 외부 전달매체로부터 수신받은 방송신호의 채널을 선택하고, 그 선택된 채널의 A/V 방송신호를 출력하는 제 1 방송수신처리모듈(310)로부터 입력받아 해당 프로그램의 방송을 사용자에게 디스플레이시키게 된다.The main TV receiver 30 in [remote location # 1] selects a channel of a broadcast signal received from an external transmission medium according to a user's input operation, and receives a first broadcast signal for outputting an A / V broadcast signal of the selected channel. It receives the input from the processing module 310 to display the broadcast of the program to the user.
