통신망의 사용여부를 알려주는 디지털 방송신호 수신장치Digital broadcasting signal receiving device to inform the use of communication network

본 발명은 디지털 방송신호 수신장치에 관한 것으로서, 특히 모뎀 및 전화기를 통해 통신망에 접속중일 때, 이를 사용자에게 알려주는 디지털 방송신호 수신장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcast signal receiving apparatus, and more particularly, to a digital broadcast signal receiving apparatus which notifies a user when connected to a communication network through a modem and a telephone.

최근, 디지털추세에 맞추어 TV방송분야에도 디지털방송의 표준화작업이 한창 진행되고 있다. 특히, 유럽에서는 유럽 최대의 방송 관련 대회인 IBC(Internation Broadcasting Convention)에서 HD-DIVINE(High Definition-Digital Video Narrow-band Emission)이라는 지상파 디지털HDTV방송이 선을 보인 다음부터 국가별, 지역별로 디지털TV방송에 관한 프로젝트가 진행되고 있다. 아울러, 이 디지털방송을 수신하여 시청할 수 있는 TV시스템도 요구되어 졌으며, 그 하나가 유럽향 디지털 TV(Digital Terrestrial Television; DTTV)이다.Recently, standardization of digital broadcasting is in full swing in the field of TV broadcasting in line with the digital trend. Particularly in Europe, terrestrial digital HDTV broadcasting called HD-DIVINE (High Definition-Digital Video Narrow-band Emission) was shown at the International Broadcasting Convention (IBC), Europe's largest broadcasting competition. A project on broadcasting is underway. In addition, there is a demand for a TV system that can receive and view digital broadcasts, one of which is Digital Terrestrial Television (DTTV) for Europe.

이러한 유럽향 디지털 TV는 디지털방송을 수신하는 기능뿐만 아니라, 통신망을 통해 데이터를 송/수신할 수 있는 모뎀을 구비하고 있다. 이 모뎀은 전화기에 연결되며, 일반전화망(PSTN)을 통해 데이터 통신이 가능하다. 일반전화망(PSTN)에는 유럽향 디지털 TV에 포함된 모뎀과, 전화기 또는 개인용컴퓨터에 포함된 모뎀이 접속하여 데이터를 주고받을 수 있다.Such digital TVs for Europe are equipped with a modem capable of transmitting / receiving data through a communication network as well as a function of receiving digital broadcasting. The modem is connected to a telephone and can communicate data over the public telephone network (PSTN). In the PSTN, a modem included in a European digital TV and a modem included in a telephone or a personal computer may be connected to each other to exchange data.

전화기를 사용하거나, 개인용 컴퓨터의 모뎀을 통해 통신을 하고 있을 때, 유럽향 디지털 TV의 모뎀을 통해 데이터를 송/수신하려고 하면 데이터의 충돌이 일어날 수 있다. 예를들어, 사용자가 거실에 있는 유럽향 디지털 TV를 통해 방송을 시청하고 있고, 방에 설치된 전화기 또는 컴퓨터를 통해 다른 사용자가 통신망에 접속을 했을 경우, 거실에서 TV방송을 시청중이던 사용자는 이를 알 수 없다. 그러므로, TV방송을 시청중이던 사용자가 시청도중, 원하는 데이터를 제공받기 위해 유럽향 디지털 TV의 모뎀을 통해 통신망에 접근(access)하면, 이미 통신망에 접속중인 전화기 또는 컴퓨터의 모뎀을 통해 송/수신중이던 데이터와 충돌이 일어날 수 있는 문제점이 있다.If you are using a telephone or communicating via a personal computer modem, attempting to send or receive data via a European digital TV modem can cause data conflicts. For example, if a user is watching a broadcast on a European digital TV in the living room and another user accesses the network through a telephone or computer installed in the room, the user who was watching the TV broadcast in the living room knows this. Can't. Therefore, if a user who is watching a TV broadcast accesses a communication network through a modem of a European digital TV to receive desired data while watching a TV broadcast, the user who is watching the TV broadcast is already transmitting / receiving through a modem of a telephone or a computer connected to the communication network. There is a problem that conflicts with data can occur.

따라서, 본 발명의 목적은 전화를 사용하거나 개인용컴퓨터의 모뎀을 통해 통신망에 접속중일 때, 이를 사용자에게 알려줌으로써 디지털 방송신호 수신장치의 모뎀을 통해 데이터를 송수신하는 것을 방지하는 디지털 방송신호 수신장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a digital broadcast signal receiving apparatus which prevents the transmission and reception of data through the modem of the digital broadcast signal receiving apparatus by informing the user when the telephone is connected to the communication network through a modem or a personal computer. In providing.

위와같은 목적을 달성하기 위한 본 발명의 특징은 디지털 방송신호 수신장치에 있어서, 전화기에 연결된 모뎀, 상기 모뎀과 일반전화망(PSTN)을 접속시키는 기능을 가지며, 상기 모뎀과 일반전화망간에 흐르는 전류값의 변화를 감지하고, 상기 현재의 전류값을 하이상태신호 또는 로우상태신호 중의 하나로 변환하여 출력하는 DAAC(Direct Access Analog Circuit), 상기 전류값에 근거하여 모뎀 또는 전화기와 상기 일반전화망과의 접속여부를 알려주는 통신망사용알림부 및 상기 DAAC로부터 하이상태신호가 인가될 때, 통신망이 사용중임을 알리는 통신망사용신호를 출력하는 제어부를 포함하는 디지털 방송신호 수신장치에 있다.A feature of the present invention for achieving the above object is a digital broadcast signal receiving apparatus, having a function of connecting a modem connected to a telephone, the modem and a general telephone network (PSTN), the current value flowing between the modem and the telephone network A DAAC (Direct Access Analog Circuit) for detecting a change in the current value and converting the current value into one of a high state signal or a low state signal, and outputting the signal, according to whether the modem or telephone is connected to the general telephone network based on the current value. And a control unit for outputting a communication network use signal indicating that the communication network is in use when a high state signal is applied from the DAAC.

이하, 첨부된 도면들을 참조하여 본 발명의 바람직한 일 실시예를 상세히 설명하겠다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따라 통신망의 사용여부를 알려주는 유럽향 디지털 텔레비젼(Digital Terrestrial Television; DTTV) 세트를 보여주는 도면이다.1 is a diagram showing a set of digital terrestrial televisions (DTTV) for Europe informing whether a communication network is used according to an embodiment of the present invention.

유럽향 디지털 TV세트는 각 부의 동작상태를 제어하는 중앙제어부(11) 및 통신망을 통해 데이터를 주고받을 수 있는 모뎀(12)을 구비한다. 실시예에서, 통신망은 일반전화망(PSTN; Public Switched Telephone Network)으로 한다. DAAC (Direct Access Analog Circuit)(13)는 모뎀(12)과 일반전화망(PSTN)과의 연결을 위한 아날로그회로이며, 통신망의 접속여부에 따라 일반전화망(PSTN)에 흐르는 전류값을 디스플레이패널에 부착된 통신망사용알림부(15)로 출력한다. 또한, 일반전화망(PSTN)을 통해 전화기 또는 모뎀을 구비한 개인용컴퓨터(PC)등이 연결된다. 일반전화선용 잭(14)은 모뎀(12)과 일반전화망을 연결시키는 모듈러 잭(modular jack)으로, 보통 RJ 11 잭이라 한다. 통신망사용알림부(15)는 직렬 연결되는 인버터(INV), 저항(R), 그리고 발광다이오드(Light-emitting diode; LED)를 포함한다. 발광다이오드(LED)는 DAAC(13)에서 검출된 전류량의 변화에 근거하여 빛을 발산하거나 빛을 발하지 않는다.The digital TV set for Europe has a central control unit 11 for controlling the operation state of each unit and a modem 12 for transmitting and receiving data through a communication network. In an embodiment, the communication network is a public switched telephone network (PSTN). The DAAC (Direct Access Analog Circuit) 13 is an analog circuit for connection between the modem 12 and the PSTN, and attaches a current value flowing through the PSTN to the display panel depending on whether the communication network is connected. Output to the communication network use notification unit 15. In addition, a personal computer (PC) having a telephone or a modem is connected through a general telephone network (PSTN). The general telephone line jack 14 is a modular jack connecting the modem 12 and the general telephone network, commonly referred to as an RJ 11 jack. The communication network use notification unit 15 includes an inverter INV, a resistor R, and a light-emitting diode (LED) connected in series. The light emitting diode LED does not emit light or emit light based on a change in the amount of current detected by the DAAC 13.

일반전화망을 통해 모뎀(12), 전화기 또는 컴퓨터의 모뎀이 접속중이면, 일반전화망(PSTN)에 흐르는 전류가 변화한다. DAAC(13)는 일반전화망(PSTN)에 흐르는 전류값을 검출하여 검출된 전류값을 하이상태신호 또는 로우상태신호 중의 하나로 변환하여 출력한다. 여기서, 하이상태신호는 5V, 로우상태신호는 0V이다. 그러므로, DAAC(13)는 일반전화망(PSTN)을 통해 모뎀(12)이 접속중일 때, 하이상태신호를 출력한다. DAAC(13)에 직렬연결된 인버터(INV)는 발광다이오드(LED)를 구동하기 위한 전류드라이버이며, 5V의 전류값은 발광다이오드(LED)에서 드라이브저항(R)을 통해 발광다이오드(LED)로 인가되고, 발광다이오드(LED)는 빛을 발산한다. 한편, 일반전화망(PSTN)을 통해 접속중이던 모뎀(12), 전화기 또는 개인용컴퓨터의 모뎀이 접속을 중지하면, 일반전화망에 흐르는 전류값이 변화하게 된다. DAAC(13)는 변화된 전류값에 근거하여 로우상태신호를 출력한다. 따라서, 통신망사용알림부(15)의 발광다이오드(LED)는 빛을 발산하지 않는다. 이러한 본 발명의 실시예는 도 2에서 보여진다. 또한, DAAC(13)는 검출된 전류값을 하이상태신호 또는 로우상태신호 중의 하나로 변환하여 제어부(11)로 출력한다. 제어부(11)는 DAAC(13)로부터 하이상태신호가 인가될 때, 통신망이 사용중임을 알리는 신호를 출력한다.When the modem 12, the telephone or the modem of the computer is connected via the general telephone network, the current flowing through the general telephone network PSTN changes. The DAAC 13 detects a current value flowing through the general telephone network PSTN, converts the detected current value into one of a high state signal or a low state signal, and outputs it. Here, the high state signal is 5V and the low state signal is 0V. Therefore, the DAAC 13 outputs a high state signal when the modem 12 is connected via the public telephone network PSTN. Inverter INV connected in series with DAAC 13 is a current driver for driving the light emitting diode LED, and a current value of 5 V is applied from the light emitting diode LED to the light emitting diode LED through the drive resistor R. The light emitting diodes (LEDs) emit light. On the other hand, when the modem 12, the telephone, or the modem of the personal computer, which are being connected through the general telephone network PSTN, stops the connection, the current value flowing through the general telephone network changes. The DAAC 13 outputs a low state signal based on the changed current value. Therefore, the light emitting diode LED of the communication network use notification unit 15 does not emit light. This embodiment of the invention is shown in FIG. 2. In addition, the DAAC 13 converts the detected current value into one of a high state signal or a low state signal and outputs it to the control unit 11. When the high state signal is applied from the DAAC 13, the control unit 11 outputs a signal indicating that the communication network is in use.

이상과 같이, 본 발명의 실시예는 발광다이오드(LED)를 이용하여 사용자에게 통신망이 사용중임을 알려준다. 또한, OSD문자로 TV화면에 표시하거나, 스피커를 통해 음성으로 출력하여 사용자에게 통신망이 사용중임을 알려주는 방법 등이 있다. 이러한 실시예가 본 발명을 반드시 한정하는 것은 아니다. 또한, 전술의 실시예는 유럽향 디지털 텔레비젼(DTTV)세트에 관련하여 설명되었다. 이러한 실시예가 본원발명을 전제하지는 않는다. 그러므로, 본원발명의 특성은 디지털 방송신호를 수신할 수 있는 모든 장치에서도 동일하게 적용할 수 있음은 당업자에게 명확하다.As described above, the embodiment of the present invention uses a light emitting diode (LED) to inform the user that the communication network is in use. In addition, there is a method such as displaying on the TV screen with OSD characters, or outputting a voice through the speaker to inform the user that the communication network is in use. These examples do not necessarily limit the invention. In addition, the foregoing embodiments have been described in connection with a set of European Digital Televisions (DTTV). Such examples do not presuppose the invention. Therefore, it is apparent to those skilled in the art that the characteristics of the present invention can be equally applied to all devices capable of receiving digital broadcast signals.

상술한 바와같이, 본 발명은 일반전화망에 흐르는 전류값에 근거하여 개인용컴퓨터의 모뎀 또는 전화기 등이 일반전화망에 접속중인지 여부를 판단하여 이를 사용자에게 알려줌으로써 안정적인 통신환경을 구축할 수 있는 효과가 있다.As described above, the present invention has an effect of establishing a stable communication environment by determining whether a modem or a telephone of a personal computer is connected to the general telephone network based on the current value flowing through the general telephone network and informing the user of the connection. .
