도 1은 본 발명의 방송 프로그램 다중표시를 위한 셋톱박스가 사용되는 환경을 설명하기 위한 도면이다.1 is a view for explaining an environment in which a set-top box is used for multiple broadcast program display of the present invention.
본 발명의 셋톱박스(100)는 케이블 TV망으로부터의 TV 신호를 텔레비젼에서 볼 수 있는 신호로 변환하여, 댁내 인터넷 망을 통하여 텔레비젼(400)로 전달한다. 셋톱박스(100)는 하나의 채널로부터의 TV 신호를 텔레비젼(400)에 전송할 수도 있지만, 복수개의 채널로부터의 TV 신호를 하나의 화면으로 구성하여 텔레비젼(400)에 전송할 수 있다. 셋톱박스(100)는 댁내의 LAN(Local Area Network)에 인터넷 공유기(300)를 통하여 무선으로 연결될 수도 있고, 유선으로 연결될 수도 있다. 셋톱박스(100)는 DLNA(Digital Living Network Alliance) 서버, 즉 DMS(Digital Media Server)로서의 기능도 수행한다. DLNA는 가정 내에 있는 단말기 간의 미디어 전송과 제어를 위한 네트워크 기술 표준으로, DLNA 가이드라인을 준수하여 개발된 단말기들은 와이파이, 이더넷, 블루투스 네트워크 환경 하에서 HTTP, RTP/RSTP 등의 인터넷 프로토콜을 이용하여 이미지, 음악, 동영상 콘텐츠를 공유할 수 있다The set-top box 100 of the present invention converts a TV signal from a cable TV network into a signal that can be viewed on a television, and transmits the signal to a television 400 through an in-house internet network. The set top box 100 may transmit a TV signal from one channel to the television 400, but may configure the TV signal from a plurality of channels into one screen and transmit the TV signal to the television 400. The set top box 100 may be wirelessly connected to the local area network (LAN) of the home through the Internet router 300 or may be connected by wire. The set top box 100 also functions as a digital living network alliance (DLNA) server, that is, a digital media server (DMS). DLNA is a network technology standard for media transmission and control between terminals in the home. The terminals developed in accordance with the DLNA guidelines use the Internet protocols such as HTTP, RTP / RSTP, etc. under the Wi-Fi, Ethernet, and Bluetooth networks. We can share music, video contents
공유기(300)에는 같은 실내에 있는 스마트폰이나 태블릿PC 등의 휴대정보단말장치(200)가 무선으로 연결된다. 본 발명에서 휴대정보단말장치(200)는 DMP (Digital Media Player) 또는 DMC (Digital Media Controller)로서 동작할 수 있다. 즉, 동작하는 모드에 따라서 셋톱박스(100)를 통해 출력되는 TV 방송을 재생하거나, 또는 텔레비젼(400)에 표시되는 다중화면 제어 등의 제어동작을 수행한다. 공유기(300)는 또한 외부 인터넷망에 연결되어, 인터넷을 통해 수신되는 동영상을 텔레비젼(400)을 통해 재생할 수도 있다.The router 300 is wirelessly connected to a portable information terminal device 200 such as a smartphone or a tablet PC in the same room. In the present invention, the portable information terminal device 200 may operate as a digital media player (DMP) or a digital media controller (DMC). That is, according to the operating mode, the TV broadcast output through the set-top box 100 is reproduced, or a control operation such as a multi-screen control displayed on the television 400 is performed. The router 300 may also be connected to an external internet network to play a video received through the television 400.
한편, 도 1에서는 공유기(300)를 사용하여 휴대정보단말장치(200)가 내부 LAN 망에 연결되는 경우를 도시하였지만, 본 발명은 공유기(300)가 아닌 무선 액세스포인트를 사용하여 연결되는 경우에도 적용 가능하다.Meanwhile, although FIG. 1 illustrates a case in which the portable information terminal device 200 is connected to the internal LAN network using the sharer 300, the present invention may be connected using a wireless access point rather than the sharer 300. Applicable
다음으로, 도 2를 참조하여 본 발명의 방송 프로그램 다중표시를 위한 셋톱박스의 내부 구성에 대해서 설명한다.Next, with reference to Figure 2 will be described the internal configuration of the set-top box for multiple broadcast program display of the present invention.
본 발명의 방송 프로그램 다중표시를 위한 셋톱박스(100)는 디지털 TV 방송신호 수신부를 통해서 디지털 TV 방송신호를 수신한다. 도 2에서는 디지털 TV 방송으로 동축케이블을 통해 전달되는 케이블 TV 신호를 수신하는 경우를 보여주고 있다. 즉, 도 2의 실시예에서 디지털 TV 방송신호 수신부는 스플리터(120)와 ATSC 인터페이스(130)를 구비한다. 스플리터(120)는 동축케이블을 통해 들어오는 신호를 받아서 둘 또는 그 이상의 신호로 분기하는 역할을 한다. 스플리터(120)에서 분기된 신호 중 하나는 셋톱박스(100)에서 디코딩하는데 사용하며, 다른 하나는 셋톱박스(100)의 OUT 단자를 통해 외부로 출력된다. ATSC 인터페이스(130)는 디지털 TV 표준인 ATSC (Advanced Television System Committee) 방식의 디지털 TV 방송신호를 수신하기 위한 모듈이다. The set-top box 100 for multi-display broadcasting program of the present invention receives the digital TV broadcast signal through the digital TV broadcast signal receiver. 2 illustrates a case in which a cable TV signal transmitted through a coaxial cable is received through digital TV broadcasting. That is, in the embodiment of FIG. 2, the digital TV broadcast signal receiver includes a splitter 120 and an ATSC interface 130. The splitter 120 receives a signal input through a coaxial cable and branches the signal into two or more signals. One of the signals branched from the splitter 120 is used to decode the set top box 100, and the other is output to the outside through the OUT terminal of the set top box 100. The ATSC interface 130 is a module for receiving a digital TV broadcast signal of an ATSC (Advanced Television System Committee) method, which is a digital TV standard.
수신된 디지털 TV 방송신호 중에서 최대 4개까지의 방송 채널의 신호가 채널 선택부(T1, T2, T3, T4)에 의해 선택된다. 제어부(110)는 디폴트 채널 또는 사용자가 선택한 채널을 선택하도록 채널 선택부(T1, T2, T3, T4)를 제어한다. 선택된 채널의 디지털 TV 방송신호는 4개의 디코더(151, 152, 153, 154)에서 각각 디코딩되어 오디오 신호와 영상 신호가 출력된다.Among the received digital TV broadcast signals, signals of up to four broadcast channels are selected by the channel selectors T1, T2, T3, and T4. The controller 110 controls the channel selectors T1, T2, T3, and T4 to select a default channel or a channel selected by the user. The digital TV broadcast signals of the selected channel are decoded by four decoders 151, 152, 153, and 154, respectively, to output audio signals and video signals.
화면구성부(160)는 제어부(110)의 제어에 따라 4개의 디코더(151, 152, 153, 154)로부터의 오디오 신호와 영상신호를 그대로 인코더(171, 172, 173, 174)로 각각 전달하거나, 또는 복수의 디코더로부터의 영상신호를 사용하여 하나의 화면신호로 구성하여 4개의 인코더 중의 하나로 출력한다. The screen configuration unit 160 delivers the audio and video signals from the four decoders 151, 152, 153, and 154 to the encoders 171, 172, 173, and 174, respectively, under the control of the controller 110. Alternatively, video signals from a plurality of decoders are used to form one screen signal and output to one of four encoders.
즉, 단일화면 모드일 때에는 화면구성부(160)는 4개의 디코더(151, 152, 153, 154)로부터의 오디오 신호와 영상신호를 그대로 인코더(171, 172, 173, 174)로 각각 전달한다. 따라서, 4개 채널의 TV 방송신호가 텔레비젼(400)과 휴대정보단말장치(200)를 포함하여 총 4개까지의 단말기로 각각 전송되고, 각 단말기에서는 각자 선택한 채널의 TV 방송이 독자적으로 재생된다. 예를 들어, 텔레비젼(400)에서는 드라마 방송을 시청하고, 아빠의 스마트폰에서는 스포츠 중계방송을, 큰애의 스마트폰에서는 음악방송을, 작은애의 태블릿 PC에서는 만화방송을 보는 것이 가능하다. 즉, 단일화면 모드에서는 휴대정보단말장치(200)는 DMP (Digital Media Player)로서 동작하게 된다.That is, in the single screen mode, the screen configuration unit 160 transfers audio and video signals from the four decoders 151, 152, 153, and 154 to the encoders 171, 172, 173, and 174, respectively. Accordingly, four channels of TV broadcast signals are transmitted to up to four terminals, including the TV 400 and the portable information terminal device 200, and each terminal independently reproduces the TV broadcast of the selected channel. . For example, it is possible to watch a drama broadcast on the TV 400, a sports broadcast broadcast on the father's smartphone, a music broadcast on the smartphone of the big boy, and a cartoon broadcast on the tablet PC of the little boy. That is, in the single screen mode, the portable information terminal device 200 operates as a digital media player (DMP).
반면, 다중화면 모드일 때에는 화면구성부(160)는 4개의 디코더(151, 152, 153, 154)로부터의 영상신호, 즉, 제1채널에서 제4채널까지의 방송 프로그램의 TV 영상신호를 도 4에서와 같이 하나의 화면으로 구성한 후에 4개의 인코더 중의 하나로 출력한다. 인코더에서는 화면구성부에서 출력되는 다중 화면신호를 디지털 TV 표준에 따른 압축영상신호로 인코딩하여 출력한다. 인코더로부터 출력되는 압축영상신호는 DLNA 서버(180)에서 DLNA 표준에 따른 신호로 변환되어 유선 또는 무선 LAN(Local Area Network)에 접속하기 위한 이더넷 인터페이스(190)를 통해 휴대정보단말장치(200) 또는 텔레비젼(400)으로 전송된다. On the other hand, in the multi-screen mode, the screen configuration unit 160 displays the video signals from the four decoders 151, 152, 153, and 154, that is, the TV video signals of the broadcast program from the first channel to the fourth channel. As shown in 4, it is composed of one screen and then output to one of four encoders. The encoder encodes and outputs a multi-screen signal output from the screen configuration unit into a compressed video signal according to the digital TV standard. The compressed video signal output from the encoder is converted into a signal according to the DLNA standard in the DLNA server 180 and is connected to the portable information terminal device 200 or via an Ethernet interface 190 for connecting to a wired or wireless local area network (LAN). Is sent to the television 400.
그러면 도 4와 같이 4개의 방송 프로그램을 하나의 화면으로 구성한 다중화면이 휴대정보단말장치(200) 또는 텔레비젼(400)에 표시되게 된다. 한편, 다중화면 모드에서 휴대정보단말장치(200) 또는 텔레비젼(400)으로 출력되는 오디오 신호는 4개의 채널 중의 미리 지정된 채널의 오디오, 예를 들면 화면의 좌상에 표시되는 채널의 오디오만이 출력되도록 구성하는 것이 가능하다. 또는, 휴대정보단말장치(200)를 사용하여 오디오가 출력되는 채널을 선택할 수 있도록 구성하는 것도 가능하다.Then, as shown in FIG. 4, the multi-screen consisting of four broadcast programs on one screen is displayed on the portable information terminal device 200 or the television 400. On the other hand, in the multi-screen mode, the audio signal output to the portable information terminal device 200 or the television 400 is such that only audio of a predetermined channel among four channels, for example, audio of a channel displayed on the left of the screen, is output. It is possible to configure. Alternatively, the portable information terminal apparatus 200 may be configured to select a channel through which audio is output.
한편, 휴대정보단말장치(200)가 아닌 텔레비젼(400) 등의 다른 DMR(400)을 선택하면, 휴대정보단말장치(200)는 DMC(Digital Media Controller)로서 동작하게 된다. 휴대정보단말장치(200)는 DMC(Digital Media Controller)로서 동작하는 DMC 모드에서는 다중화면 모드에서 각 화면에 표시될 채널의 선택, 다중화면 모드로의 진입 및 DMC 모드 종료 등의 동작은 휴대정보단말장치(200)에서 수행하게 된다. On the other hand, if another DMR 400 such as a television 400 is selected instead of the portable information terminal device 200, the portable information terminal device 200 operates as a digital media controller (DMC). In the DMC mode operating as the DMC (Digital Media Controller), the portable information terminal device 200 performs operations such as selecting a channel to be displayed on each screen in the multi-screen mode, entering the multi-screen mode, and ending the DMC mode. It is performed in the device 200.
DMC (Digital Media Controller)로서 동작하는 휴대정보단말장치(200)로부터의 제어명령은 이더넷 인터페이스(190)를 통해 DLNA 서버(180)에서 수신되며, 수신된 제어명령에 따라 제어부(110)는 셋톱박스(100)의 각 구성요소를 제어한다. 한편, DMP (Digital Media Player)로서 동작하는 휴대정보단말장치(200)로부터의 제어명령도 이더넷 인터페이스(190)를 통해 DLNA 서버(180)에서 수신되며, 수신된 제어명령에 따라 제어부(110)는 셋톱박스(100)의 각 구성요소를 제어한다. DMC (Digital Media Controller)로서 동작하는 휴대정보단말장치(200)로부터의 제어명령은 텔레비젼(400)에 표시되는 다중화면을 구성하는 채널의 변경 및 다중화면 모드의 취소, DMC 모드종료 등의 제어명령을 포함하며, DMP (Digital Media Player)로서 동작하는 휴대정보단말장치(200)로부터의 제어명령은 해당 휴대정보단말장치(200)에 표시되는 방송화면의 채널의 선택, 오디오 볼륨의 조정, 다중화면 모드로의 진입 등을 포함한다.The control command from the portable information terminal device 200 operating as a digital media controller (DMC) is received from the DLNA server 180 through the Ethernet interface 190, and the control unit 110 is set-top box according to the received control command. Each component of 100 is controlled. Meanwhile, a control command from the portable information terminal apparatus 200 operating as a digital media player (DMP) is also received by the DLNA server 180 through the Ethernet interface 190. The control unit 110 according to the received control command Each component of the set top box 100 is controlled. The control command from the portable information terminal apparatus 200 operating as a DMC (Digital Media Controller) is a control command for changing a channel constituting the multi-screen displayed on the television 400, canceling the multi-screen mode, terminating the DMC mode, and the like. The control command from the portable information terminal apparatus 200 operating as a digital media player (DMP) includes a selection of a channel of a broadcast screen displayed on the portable information terminal apparatus 200, an adjustment of an audio volume, and a multi-screen. Entry to the mode, and the like.
한편, 휴대정보단말장치(200)로부터 다중화면 모드로의 진입을 요청하는 제어명령에는 다중화면 모드에서 표시할 4개의 채널에 관한 정보가 포함될 수도 있고 포함되어 있지 않을 수도 있다. 휴대정보단말장치(200)로부터의 제어명령에 4개의 채널에 관한 정보가 없는 경우에는 제어부(110)가 이전에 선택되었던 4개의 채널을 상기 4개의 채널로 선택하도록 구성할 수 있다. 이를 위하여 셋톱박스(100)에는 이전에 선택되었던 채널에 관한 정보를 저장하기 위한 불활성 메모리가 구비될 수 있다. The control command for requesting entry into the multi-screen mode from the portable information terminal apparatus 200 may or may not include information about four channels to be displayed in the multi-screen mode. If the control command from the portable information terminal device 200 does not have information about four channels, the controller 110 may be configured to select the four channels previously selected as the four channels. To this end, the set top box 100 may be provided with an inactive memory for storing information about a channel previously selected.
실시예에 따라서는, 셋톱박스(100)에 이러한 정보를 저장하는 것이 아니라, 다중화면을 구성하는 4개의 채널에 관한 정보를 항상 휴대정보단말장치(200)에서 보내도록 구성할 수도 있다. 사용자가 4개의 채널을 지정하지 않고 다중화면 모드로의 진입을 요청한 경우에는 휴대정보단말장치(200)에서 이전에 보았던 4개의 채널을 선택하여 다중화면 모드로의 진입 제어명령에 이들 4개의 채널에 관한 정보를 포함시키도록 하거나, 디폴트로 지정된 4개의 채널에 관한 정보를 다중화면 모드로의 진입 제어명령에 포함시키도록 할 수 있다.According to an exemplary embodiment, rather than storing such information in the set-top box 100, the portable information terminal apparatus 200 may always transmit information about four channels constituting a multi-screen. If the user requests to enter the multi-screen mode without specifying four channels, the mobile information terminal device 200 selects the four channels previously seen and sends them to the multi-screen mode control command. Information about the four channels specified by default may be included in the entry control command to the multi-screen mode.
다음으로 도 3을 참조하여 셋톱박스와 휴대정보단말장치 및 텔레비젼 사이의 동작 흐름에 대해서 설명한다. 도 3은 휴대정보단말장치를 사용하여 본 발명의 방송 프로그램 다중표시를 위한 셋톱박스를 제어할 때의 데이터 흐름을 보여주는 도면이다.Next, an operation flow between the set top box, the portable information terminal device and the television will be described with reference to FIG. 3. 3 is a view showing a data flow when controlling a set-top box for multiple display of a broadcast program of the present invention using a portable information terminal device.
먼저, 사용자는 휴대정보단말장치(200)에 본 발명의 방송 프로그램 다중표시 제어를 위한 애플리케이션(이하, '방송 다중표시 애플리케이션'이라 함)을 설치하고 실행한다(단계 501). First, the user installs and executes an application (hereinafter, referred to as a broadcast multi-display application) for broadcast program multi-display control in the portable information terminal apparatus 200 (step 501).
또한, 셋톱박스(100)에 전원을 인가하면 셋톱박스(100)는 파워온 리셋(Power-on reset) 되어 DLNA 서버(180)의 초기화가 이루어진다(단계 601). 즉, 셋톱박스(100)가 파워온 리셋되면 제어부(110)는 디지털 TV 방송신호 수신부를 통해 들어오는 방송신호에 포함된 채널들을 스캔하여 메모리에 저장하여 두고, DLNA 서버 기능을 스타트 시킨다. DLNA 서버(180)는 주기적으로 DMP나 DMC가 존재하는지를 스캔한다.In addition, when power is applied to the set-top box 100, the set-top box 100 is a power-on reset to initialize the DLNA server 180 (step 601). That is, when the set-top box 100 is powered on and reset, the controller 110 scans and stores the channels included in the broadcast signal received through the digital TV broadcast signal receiver in memory and starts the DLNA server function. The DLNA server 180 periodically scans whether DMP or DMC exists.
셋톱박스(100)가 초기화된 상태에서 휴대정보단말장치(200)에서 방송 다중표시 애플리케이션을 실행시키면, 방송 다중표시 애플리케이션은 DLNA 서버를 검색하여(단계 503), 검색된 DLNA 서버 중에서 사용자가 선택한 DLNA 서버(180)로부터 채널 정보를 받는다(단계 602, 단계 505). 또한, 텔레비젼(400)도 파워온 되면 DLNA 서버를 검색하여 DLNA 서버에 관한 정보를 저장한다(단계 701). 그리고, 방송 다중표시 애플리케이션은 동일한 LAN에 연결되어 있는 텔레비젼(400)을 DMR(Digital Media Renderer)로 등록하여둔다.When the broadcast multi-display application is executed in the portable information terminal apparatus 200 in the state where the set-top box 100 is initialized, the broadcast multi-display application searches for a DLNA server (step 503), and the DLNA server selected by the user among the searched DLNA servers. Channel information is received from 180 (step 602, step 505). In addition, when the TV 400 is powered on, the TV 400 searches for a DLNA server and stores information about the DLNA server (step 701). The broadcast multi-display application registers the television 400 connected to the same LAN as a digital media renderer (DMR).
DLNA 서버(180)는 DLNA 표준에 따른 압축영상신호로 인코딩된 특정 채널(제1채널)의 방송 프로그램을 LAN을 통해 해당 채널을 요청한 DMP에 전송하고(단계 603), 휴대정보단말장치(200)는 수신되는 방송 프로그램을 재생한다(단계 507). 방송 프로그램은 처음에는 디폴트 채널의 방송 프로그램을 전송하도록 하고, 사용자가 휴대정보단말장치(200)를 사용하여 채널을 선택하면 해당 채널의 방송 프로그램을 전송하도록 구성할 수 있다.The DLNA server 180 transmits a broadcast program of a specific channel (first channel) encoded with a compressed video signal according to the DLNA standard to a DMP requesting the corresponding channel through a LAN (step 603), and the portable information terminal device 200 Reproduces the received broadcast program (step 507). The broadcast program may be configured to transmit a broadcast program of a default channel at first, and to transmit a broadcast program of a corresponding channel when the user selects a channel using the portable information terminal device 200.
이와 같이 휴대정보단말장치(200)가 DMP로서 동작하면서 방송 프로그램을 재생하고 있을 때에, 사용자가 방송 다중표시 애플리케이션에 마련되어 있는 캐스트 버튼을 누르면(단계 509), 휴대정보단말장치(200)의 방송 다중표시 애플리케이션은 재생가능한 DMR을 검색하여 표시한다(단계 511). 그러면, 사용자는 표시된 DMR 중에서 원하는 DMR을 선택하고(단계 513), 방송 다중표시 애플리케이션은 해당 휴대정보단말장치(200)를 DMC(Digital Media Controller)로 전환시키고, DLNA 서버(180)는 해당 휴대정보단말장치(200)로의 인코딩된 신호 전송을 중단하며, 화면모드에 따라서 단일 영상신호 또는 복수의 영상신호를 사용하여 단일화면 신호 또는 복수의 영상이 하나의 화면으로 구성된 하나의 다중화면 신호를 선택된 DMR(Digital Media Renderer)로 출력하도록 제어한다. 즉, DMC로서 동작하게 된 휴대정보단말장치(200)의 방송 다중표시 애플리케이션은 채널에 관한 정보(주소값)를 선택된 DMR로서의 텔레비젼(400)에 전송한다(단계 515). As described above, when the portable information terminal apparatus 200 operates as a DMP and reproduces a broadcast program, when the user presses the cast button provided in the broadcast multi-display application (step 509), the broadcast multiplexing of the portable information terminal apparatus 200 is performed. The display application retrieves and displays the playable DMR (step 511). Then, the user selects a desired DMR among the displayed DMRs (step 513), and the broadcast multi-display application switches the corresponding portable information terminal device 200 to a digital media controller (DMC), and the DLNA server 180 selects the corresponding portable information. The DMR stops transmitting the encoded signal to the terminal device 200 and selects a single screen signal or a multi-screen signal in which a plurality of images are configured as one screen using a single video signal or a plurality of video signals according to the screen mode. Control to output to (Digital Media Renderer). That is, the broadcast multi-display application of the portable information terminal apparatus 200 which has been operated as a DMC transmits information about the channel (address value) to the television 400 as the selected DMR (step 515).
이후부터는 셋톱박스(100)에서 텔레비젼(400)으로 화면모드에 따라 단일화면 신호 또는 다중화면 신호가 전송된다(단계 605). 즉, 다중화면 모드에서는 도 4와 같은 다중화면 신호가 텔레비젼(400)으로 전송되며, 텔레비젼(400)은 이를 재생한다(단계 703).Subsequently, a single screen signal or a multi-screen signal is transmitted from the set top box 100 to the television 400 according to the screen mode (step 605). That is, in the multi-screen mode, the multi-screen signal as shown in FIG. 4 is transmitted to the television 400, and the television 400 reproduces it (step 703).
이와 같이 다중화면 모드에서 복수 채널의 방송 프로그램이 도 4와 같은 형태로 텔레비젼(400)에서 방송되는 상태에서 사용자는 DMC로 동작하고 있는 휴대정보단말장치(200)를 사용하여 화면에 표시될 방송 채널을 선택하거나 표시 위치를 변경하는 등의 동작을 수행할 수 있다.As described above, in the multi-screen mode, a broadcast channel of a plurality of channels is broadcast on the television 400 in the form as shown in FIG. Can be selected or the display position can be changed.
또한, 사용자는 DMC로 동작하고 있는 휴대정보단말장치(200)를 사용하여 DMC 종료 버튼을 선택할 수 있다. DMC 종료 버튼이 선택되면(단계 517), 휴대정보단말장치(200)는 DMC 모드종료 제어명령을 DLNA 서버(180)로 전송한다(단계 519). 방송 다중표시 애플리케이션은 해당 휴대정보단말장치(200)를 DMP로 전환하고, DLNA 서버(180)는 휴대정보단말장치(200)로부터의 DMC 모드종료 제어명령에 따라 이전 DMR에 전송되던 다중화면 신호를 휴대정보단말장치(200)로 전송한다(단계 607). 그러면, 텔레비젼(400)에서의 다중화면 표시는 종료되고 휴대정보단말장치(200)에서는 텔레비전(400)에서 방송되던 다중화면이 표시된다(단계 521).In addition, the user may select the DMC end button by using the portable information terminal device 200 operating as the DMC. When the DMC end button is selected (step 517), the portable information terminal device 200 transmits a DMC mode end control command to the DLNA server 180 (step 519). The broadcast multi display application converts the corresponding portable information terminal device 200 to DMP, and the DLNA server 180 receives the multi-screen signal transmitted to the previous DMR according to the DMC mode end control command from the portable information terminal device 200. The mobile information terminal 200 transmits to the portable information terminal device 200 (step 607).
