이하에서는 도면을 참조하여 본 발명을 보다 상세하게 설명한다. Hereinafter, with reference to the drawings will be described the present invention in more detail.

도 2는 본 발명의 일 실시예에 따른 방송수신장치에 대한 블럭도이다. 도 2를 참조하면, 본 방송수신장치는, 다이플렉서(110), 튜너(120), 케이블 모뎀(130), 케이블카드(140), OOB 모뎀(150), 스위칭부(160) 및 제어부(170)를 포함한다.2 is a block diagram of a broadcast receiving apparatus according to an embodiment of the present invention. 2, The broadcast receiving apparatus includes a diplexer 110, a tuner 120, a cable modem 130, a cable card 140, an OOB modem 150, a switching unit 160, and a control unit 170.

다이플렉서(110)는 주파수가 서로 다른 두 신호를 동시에 송수신하는 분기용 필터 소자로, 방송국으로부터 전송된 다운스트림 데이터를 수신하고, 동시에 업스트림 데이터를 방송국으로 전송한다. 다이플렉서(110)는 고역통과필터(HPF)와 저역통과필터(LPF)의 조합으로 하나의 채널/선로에 주파수가 서로 다른 두 개의 신호를 전송한다.The diplexer 110 is a branch filter element that simultaneously transmits and receives two signals having different frequencies. The diplexer 110 receives downstream data transmitted from a broadcasting station and simultaneously transmits upstream data to the broadcasting station. The diplexer 110 transmits two signals having different frequencies on one channel / line in a combination of a high pass filter (HPF) and a low pass filter (LPF).

튜너(120)는 방송국으로부터 사용자가 선택한 채널에 대응되는 방송신호를 수신하여 선국한다. The tuner 120 receives and tunes a broadcast signal corresponding to a channel selected by a user from a broadcast station.

케이블 모뎀(130)은 케이블 네트워크를 사용하여 양방향으로 데이터를 전송한다. 즉, 케이블 모뎀(130)은 튜너(120)로부터 제공되는 다운스트림 신호를 후술될 제어부(170)로 전송하고, 제어부(170)로부터 수신된 업스트림 신호를 변조 및 증폭하여 출력한다.The cable modem 130 transmits data in both directions using a cable network. That is, the cable modem 130 transmits the downstream signal provided from the tuner 120 to the controller 170 to be described later, and modulates and amplifies the upstream signal received from the controller 170.

케이블 카드(140)는 서비스 가입자 인증 및 가입자별 서비스 사용권한을 제어한다. 구체적으로, 튜너(110)를 통해 암호화된 방송신호가 수신되면, 케이블 카드(140)는 암호화된 방송신호에 대한 서비스 사용권한이 있을 경우 암호화된 방송신호를 복호화하여 출력한다. The cable card 140 controls service subscriber authentication and service permission for each subscriber. Specifically, when the encrypted broadcast signal is received through the tuner 110, the cable card 140 decrypts and outputs the encrypted broadcast signal when there is a service use right for the encrypted broadcast signal.

OOB 모뎀(150)은 케이블 카드(140)로부터 수신된 디지털 신호를 아날로그 신호로 변조한다.The OOB modem 150 modulates the digital signal received from the cable card 140 into an analog signal.

제어부(170)는 케이블 카드(140)와의 통신을 통해 방송수신장치(100)의 통신방식을 결정한다. 그리고, 제어부(170)는 결정된 통신방식에 따라 변조된 신호가 소정 경로로 전송되도록 스위칭부(160)를 제어한다. The controller 170 determines the communication method of the broadcast receiving device 100 through communication with the cable card 140. The controller 170 controls the switching unit 160 to transmit a modulated signal through a predetermined path according to the determined communication method.

즉, 제어부(170)는 방송수신장치(100)에 전원이 공급되면, 케이블 카드(140)로 방송수신장치(100)의 통신방식을 묻는 쿼리신호를 전송하고, 케이블 카드(140)로부터 쿼리신호에 대한 응답신호가 수신되면, 제어부(170)는 응답신호에 포함된 방송수신장치(100)의 통신방식에 따라 스위칭부(160)를 제어한다. 이때, 방송수신장치(100)의 통신방식은 케이블 카드(140)에 기설정되어 있으며, 케이블 카드(140)는 OOB방식 및 DSG방식을 모두 지원하도록 구성될 수 있다.That is, when power is supplied to the broadcast receiving device 100, the control unit 170 transmits a query signal for the communication method of the broadcast receiving device 100 to the cable card 140, and the query signal from the cable card 140. When the response signal is received, the controller 170 controls the switching unit 160 according to the communication method of the broadcast receiving apparatus 100 included in the response signal. At this time, the communication method of the broadcast receiving device 100 is preset in the cable card 140, the cable card 140 may be configured to support both OOB method and DSG method.

그리고, 제어부(170)는 케이블 카드(140)로부터 수신된 응답신호에 포함된 방송수신장치(100)의 통신방식이 DSG방식이면, 스위칭부(160)와 케이블 모뎀(130)이 연결되도록 A 포트를 활성화(enable)하고, 방송수신장치(100)의 통신방식이 OOB방식이면, 스위칭부(160)와 OOB 모뎀(150)이 연결되도록 B 포트를 활성화(enable) 한다. 이에 따라, 방송수신장치(100)의 통신방식이 DSG 방식인 경우, 케이블 모뎀(130)에서 변조 및 증폭된 신호가 스위칭부(160)를 통해 다이플렉서(110)로 전송되고, 방송수신장치(100)의 통신방식이 OOB 방식인 경우, OOB 모뎀(150)에서 변조 된 신호가 스위칭부(160)를 통해 다이플렉서(110)로 전송된다.If the communication method of the broadcast receiving apparatus 100 included in the response signal received from the cable card 140 is a DSG method, the control unit 170 connects the switching unit 160 and the cable modem 130 to the A port. Enable (enable), and if the communication method of the broadcast receiving device 100 is the OOB method, enable the B port so that the switching unit 160 and the OOB modem 150 is connected. Accordingly, when the communication method of the broadcast receiving device 100 is a DSG method, a signal modulated and amplified by the cable modem 130 is transmitted to the diplexer 110 through the switching unit 160, and the broadcast receiving device When the communication method of 100 is an OOB method, a signal modulated by the OOB modem 150 is transmitted to the diplexer 110 through the switching unit 160.

Referring to FIG. 3, first, the controller 170 determines a communication method of the broadcast receiving apparatus 100 through communication with a cable card 140 (S310).

즉, 제어부(170)는 방송수신장치(100)에 전원이 공급되면, 케이블 카드(140)로부터 방송수신장치(100)의 통신방식을 묻는 쿼리신호에 대한 응답을 수신함으로써 방송수신장치(100)의 통신방식을 판단한다. 이때, 방송수신장치(100)의 통신방식은 케이블 카드(140)에 기설정되어 있으며, 케이블 카드(140)는 OOB방식 및 DSG방식을 모두 지원하도록 구성될 수 있다.That is, when power is supplied to the broadcast receiving device 100, the control unit 170 receives a response to a query signal for the communication method of the broadcast receiving device 100 from the cable card 140, thereby receiving the broadcast receiving device 100. Determine communication method of. At this time, the communication method of the broadcast receiving device 100 is preset in the cable card 140, the cable card 140 may be configured to support both OOB method and DSG method.

이어, 방송수신장치(100)의 통신방식이 DSG 방식으로 판단되면, 제어부(170)는 스위칭부(160)의 A 포트를 활성화하고, B포트를 비활성화함으로써, 케이블모뎀(130)과 스위칭부(160)를 연결한다(S320).Subsequently, if it is determined that the communication method of the broadcast receiving device 100 is the DSG method, the controller 170 activates the A port of the switching unit 160 and deactivates the B port, thereby causing the cable modem 130 and the switching unit ( 160 is connected (S320).

그리고, 방송수신장치(100)의 통신방식이 OOB 방식으로 판단되면, 제어부(170)는 스위칭부(160)의 B 포트를 활성화하고, A 포트를 비활성화함으로써, OOB 모뎀(150)과 스위칭부(160)를 연결한다(S330).If the communication method of the broadcast receiving apparatus 100 is determined as the OOB method, the controller 170 activates the B port of the switching unit 160 and deactivates the A port, thereby causing the OOB modem 150 and the switching unit ( 160 is connected (S330).

이어, 스위칭부(160)는 활성화된 포트를 통해 스위칭부(160)와 연결된 케이블 모뎀(130) 또는 OOB 모뎀(150)으로부터 수신된 신호를 다이플렉서(110)로 전송 한다.(S340)Subsequently, the switching unit 160 transmits a signal received from the cable modem 130 or the OOB modem 150 connected to the switching unit 160 to the diplexer 110 through the activated port (S340).

이상 설명한 바와 같이, 본 발명에 따르면, 방송수신장치의 통신방식에 따라 스위칭부를 제어하여 스위칭부로 수신된 신호를 다이플렉서로 출력함으로써, 컴바이너 사용시 발생되는 신호 감쇠가 발생하지 않을 뿐만 아니라, 컴바이너보다 저렴한 스위치로의 대체 사용으로 인해 방송수신장치의 가격 또한 절약될 수 있다. As described above, according to the present invention, by controlling the switching unit according to the communication method of the broadcast receiving apparatus and outputting the signal received by the switching unit to the diplexer, the signal attenuation generated when using the combiner does not occur, The cost of broadcasting receivers can also be reduced by using alternatives to switches that are cheaper than combiners.
