모뎀의 사용가능여부를 알려주는 디지털방송수신기Digital broadcast receiver tells you whether or not your modem is available

본 발명은 디지털방송수신기에 관한 것으로, 특히, 사용자가 디지털방송수신기에 내장된 모뎀을 사용하고자 할 때, 일반전화망에 접속된 모뎀의 사용가능상태를 감지하여 모뎀의 사용가능여부를 알려주는 디지털방송수신기에 관한 것이다.The present invention relates to a digital broadcast receiver, and in particular, when a user wants to use a modem built in a digital broadcast receiver, digital broadcasting which detects the availability of a modem connected to a general telephone network and indicates whether the modem can be used. To a receiver.

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 디지털 HDTV방송이 선을 보인 다음부터 국가별, 지역별로 디지털 TV방송에 관한 프로젝트가 진행되고 있다. 아울러, 이 디지털방송을 수신하여 시청할 수 있는 TV시스템도 요구되어 졌으며, 그 하나가 유럽향 디지털TV 즉, DTTV(digital terrestrial television)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 IBC (internation broadcasting convention), the largest broadcasting-related competition in Europe. A project on broadcasting is underway. In addition, a TV system capable of receiving and watching digital broadcasting has been required, and one of them is a European digital TV, that is, a digital terrestrial television (DTTV).

이러한 DTTV는 디지털방송을 수신하는 기능뿐만 아니라, 통신망을 통해 데이터를 송/수신할 수 있는 모뎀을 구비하고 있다.The DTTV is equipped with a modem capable of transmitting / receiving data through a communication network as well as a function of receiving digital broadcasting.

그러나, 일반적인 모뎀의 경우, 모뎀이 접속되는 일반전화망(PSTN; public switched telephone network)이 사용상태인 경우 사용자가 모뎀을 통해 데이터를 송수신하기 위해 전화걸기를 시도 했을 경우, 전화걸기를 시도한 후, 일정시간 경과 후에 통화중이라는 것을 알 수 있다.However, in the case of a general modem, when a public switched telephone network (PSTN) to which a modem is connected is in use, when a user attempts to make a call to send and receive data through a modem, the user may try to make a call after You can see that you are on the phone after a while.

따라서, 사용자가 디지털방송수신기의 모뎀을 통해 데이터를 송수신하고자할 때도 일반전화망이 사용중인지를 체크하는데 시간이 소요되는 문제점이 있었다.Therefore, when the user wants to transmit and receive data through the modem of the digital broadcasting receiver, there is a problem that it takes time to check whether the general telephone network is in use.

따라서, 본 발명의 목적은 전술한 문제점을 해결할 수 있도록 디지털방송수신기에 내장되어 있는 모뎀을 사용하고자할 때 일반전화망(PSTN)이 사용중인지를 체크하여 모뎀의 사용가능여부를 알려주는 디지털방송수신기를 제공함에 있다.Therefore, an object of the present invention is to check whether the modem is in use when the modem is in use when the modem embedded in the digital broadcast receiver is intended to solve the above problems. In providing.

이와 같은 목적을 달성하기 위한 본 발명에 따른 모뎀의 사용가능여부를 알려주는 디지털방송수신기는 모뎀과, 모뎀과 일반전화망(PSTN)을 접속시키는 기능을 가지며, 모뎀이 아닌 다른 통신기기가 일반전화망에 접속되어있는지의 여부를 감지하여 감지신호를 출력하는 DAA부 및 DAA부의 감지신호에 따라 모뎀의 사용가능여부를 디지털방송수신기의 화면에 디스플레이하도록 제어하는 제어부를 포함한다.Digital broadcast receiver that informs the availability of the modem according to the present invention for achieving the above object has a function of connecting the modem, the modem and the public telephone network (PSTN), other communication devices other than the modem to the general telephone network And a control unit for controlling whether the modem is available on the screen of the digital broadcasting receiver according to the detection signal of the DAA unit and the DAA unit outputting the detection signal by detecting whether it is connected.

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

도 1은 본 발명에 따른 모뎀의 사용가능여부를 알려주는 디지털방송수신기를 설명하기 위한 블록도이다. 도 1 장치는 각 구성을 제어하는 제어부(11), 제어부(11)에 연결되어 통신망을 통해 데이터를 주고받을 수 있는 모뎀(12), 모뎀(12)에 연결된 아날로그회로인 DAA(Direct Access Analog)부(13) 및 DAA부(13)와 일반전화망(PSTN)을 연결시키는 잭(14)을 구비한다. 여기서, 잭(14)은 보통 RJ11잭을 사용한다. 도 1장치는 또한, 제어부(11)의 출력단에 디스플레이부(15)를 구비한다.1 is a block diagram illustrating a digital broadcast receiver for notifying whether a modem can be used according to the present invention. 1 is a control unit 11 for controlling each component, a modem 12 connected to the control unit 11 to transmit and receive data through a communication network, and a direct access analog (DAA) which is an analog circuit connected to the modem 12. And a jack 14 for connecting the unit 13 and the DAA unit 13 to the public telephone network (PSTN). Here, the jack 14 usually uses an RJ11 jack. 1 further includes a display unit 15 at the output of the control unit 11.

도 1장치에서, DAA부(13)는 모뎀(12)과 통신망과의 연결을 위한 아날로그회로이며, 일반전화망(PSTN)에 흐르는 전류변화량을 감지하여 출력하는 루프전류센서(loop current sensor : 이하 LCS라 함)를 가진다. LCS는 일반전화망(PSTN)이 접속중일 때 DAA부(13)에 흐르는 일정전류량을 감지하여 하이레벨의 신호를 출력하고, 그렇지 않으면 로우레벨의 신호를 제어부(11)로 출력한다. 제어부(11)는 DAA부(13)로부터 입력되는 신호에 따라 디스플레이부(15)에 모뎀의 사용가능상태를 디스플레이하도록 한다.In the apparatus of FIG. 1, the DAA unit 13 is an analog circuit for connection between the modem 12 and a communication network, and a loop current sensor (hereinafter referred to as LCS) for sensing and outputting a current change amount flowing through a general telephone network (PSTN). ). The LCS senses a certain amount of current flowing through the DAA unit 13 when the general telephone network PSTN is connected, and outputs a high level signal. Otherwise, the LCS outputs a low level signal to the control unit 11. The control unit 11 causes the display unit 15 to display the available state of the modem according to the signal input from the DAA unit 13.

이러한, 도 1 장치의 동작을 도 2를 참조하여 좀 더 구체적으로 설명한다. 도 2는 도 1제어부의 제어흐름도이다. 모뎀(12)이 온된 상태에서, 사용자는 키입력부(미도시)로부터 모뎀(12)을 사용하기 위한 송/수신명령을 인가한다(단계 210). 제어부(11)는 모뎀(12)을 사용하기 위한 송/수신명령이 인가되면, DAA부(13)의 LCS로부터 입력되는 신호가 하이레벨인지를 판단한다(단계 220). 판단결과, 제어부(11)는 입력되는 신호가 하이레벨의 신호라고 판단되면, 디스플레이부(15)로 전화를 사용중입니다라는 통화중메세지를 디스플레이하도록 제어한다(단계 230). 한편, 제어부(11)는 입력되는 신호가 하이레벨의 신호가 아니라고 판단되면, 디스플레이부(15)로 전화를 걸고 있습니다. 잠시만 기다려 주십시요라는 사용가능메세지를 디스플레이하도록 제어한다(단계 240). 그런 다음, 제어부(11)는 사용자의 모뎀송/수신명령에 따라 송/수신동작을 시작한다(단계 250). 제어부(11)는 모뎀송/수신이 완료되었는지를 판단한다(단계 260). 판단결과, 모뎀의 송/수신이 완료되었으면 종료한다.The operation of the device of FIG. 1 will be described in more detail with reference to FIG. 2. FIG. 2 is a control flowchart of the controller of FIG. 1. With the modem 12 turned on, the user applies a transmit / receive command for using the modem 12 from a key input unit (not shown) (step 210). When the transmission / reception command for using the modem 12 is applied, the control unit 11 determines whether the signal input from the LCS of the DAA unit 13 is high level (step 220). If it is determined that the input signal is a high level signal, the control unit 11 controls the display unit 15 to display a busy message indicating that the phone is in use (step 230). On the other hand, if it is determined that the input signal is not a high level signal, the control unit 11 makes a call to the display unit 15. Control to display the available message Please wait a moment (step 240). Then, the control unit 11 starts a transmission / reception operation according to the user's modem transmission / reception command (step 250). The control unit 11 determines whether modem transmission / reception is completed (step 260). As a result of the determination, the modem terminates when the transmission / reception is completed.

전술한 실시예에서는, 모뎀이 온된 상태에서 설명하였으나, 모뎀이 오프인 상태에서 전화걸기명령을 인가하는 경우에도 동일기능을 수행할 수 있음은 해당분야의 기술자에게는 자명하다.In the above-described embodiment, the modem has been described in the on state, but it is apparent to those skilled in the art that the same function can be performed even when the dialing command is applied while the modem is in the off state.

상술한 바와 같이, 본 발명은 사용자가 디지털방송수신기의 모뎀을 사용하고자할 때 일반전화망이 사용중인지를 알려주므로 모뎀의 사용가능여부를 알 수 있다.As described above, the present invention tells whether the general telephone network is in use when the user wants to use the modem of the digital broadcasting receiver, so that the modem can be used.
