Referring to FIG. 2 attached to the operation of the present invention configured as described above. It will be described in detail as follows.
디지털 티브이(10)의 튜너(11)는 사용자에 의해 선국된 채널을 통해 디지털 방송국에서 송출하는 방송데이터 스트림을 수신한다.(S1)The tuner 11 of the digital TV 10 receives a broadcast data stream transmitted from a digital broadcasting station through a channel tuned by a user (S1).
데이터 분리기(12)는 상기 튜너(11)에서 출력되는 방송데이터 스트림을 분석하여 홈네트워크기기용 응용데이터와 디지털방송용 데이터(오디오 데이터, 비디오 데이터, 정보 데이터)를 분리 검출하여 그 디지털방송용 데이터는 방송데이터 처리모듈(13)에 출력하고, 홈네트워크기기용 응용데이터는 응용데이터 처리모듈(15)에 출력한다.(S2-S4)The data separator 12 analyzes the broadcast data stream output from the tuner 11 to separate and detect application data for home network devices and data for digital broadcasting (audio data, video data, information data) and broadcast the data for digital broadcasting. The data is output to the data processing module 13, and the application data for the home network device is output to the application data processing module 15. (S2-S4)
상기 방송데이터 처리모듈(13)은 입력된 디지털방송용 데이터를 해석처리하고, 방송데이터 표시모듈(14)은 상기 해석 처리된 비디오 데이터와 정보 데이터를 화면상에 체계적으로 디스플레이하게 된다.(S6)The broadcast data processing module 13 interprets the input digital broadcasting data, and the broadcast data display module 14 systematically displays the analyzed video data and information data on the screen (S6).
한편, 상기 응용데이터 처리모듈(15)은 상기 데이터 분리기(12)로부터 입력되는 홈네트워크기기용 응용데이터를 응용데이터 저장모듈(16)에 임시 저장한 후 홈 네트워크기기의 식별번호(ID)를 검출하여 그 응용데이터와 함께 홈네트워크 미들웨어(17)측으로 출력한다.(S7)On the other hand, the application data processing module 15 temporarily stores the application data for the home network device input from the data separator 12 in the application data storage module 16 and detects the identification number (ID) of the home network device. And outputs it to the home network middleware 17 together with the application data. (S7)
상기 홈네트워크 미들웨어(17)는 홈 네트워크에 연결된 모든 기기에 대한 목록을 작성하여 보관하고 있는데, 이 목록을 근거로 해당 식별번호(ID)를 갖는 홈 네트워크기기(20)를 인식한 후 입력된 응용데이터를 송신하는데 적당한 형태로 가공하고, 상기 식별번호(ID)에 상응되는 식별코드를 부가하여 출력한다.(S8)The home network middleware 17 prepares and stores a list of all devices connected to the home network, and the application inputted after recognizing the home network device 20 having the corresponding identification number (ID) based on the list. The data is processed into a form suitable for transmitting data, and an identification code corresponding to the identification number is added and output.
상기 홈네트워크 미들웨어(17)에서 출력되는 응용데이터는 통신모뎀(18A)을 통해 소정의 형식으로 변조된 후 물리적인 전송매체를 통해 홈 네트워크 상에 연결된 여러 홈네트워크기기로 전송되는데, 여기서는 하나의 홈 네트워크기기(예: 냉장고)(20)가 연결된 것을 예로하였다.(S9)The application data output from the home network middleware 17 is modulated into a predetermined format through the communication modem 18A and then transmitted to various home network devices connected to the home network through a physical transmission medium. As an example, a network device (eg, a refrigerator) 20 is connected.
따라서, 상기 홈 네트워크기기(20)의 통신모뎀(21A)에서는 상기 통신모뎀(18A)으로부터 전송되는 응용데이터를 수신처리하여 자신의 식별코드와 동일한 식별코드가 검출되면 그 응용데이터를 홈네트워크 미들웨어(22)를 통해 응용데이터 처리모듈(23)측으로 출력한다.(S10)Therefore, the communication modem 21A of the home network device 20 receives and processes the application data transmitted from the communication modem 18A and detects the same application code as its own identification code. Outputs to the application data processing module 23 through 22. (S10)
이때, 상기 응용데이터 처리모듈(23)은 입력되는 응용데이터(예: 오늘의 식단정보)를 원래의 형태로 복원하여 저장하거나 곧바로 냉장고에 설치되어 있는 응용데이터 표시모듈(24)에 디스플레이하므로 사용자는 별다른 수고 없이 그 식단정보를 열람할 수 있게 된다.(S11)At this time, the application data processing module 23 restores the application data (for example, today's diet information) inputted to its original form, or stores the application data directly on the application data display module 24 installed in the refrigerator. The diet information can be read without any trouble. (S11)
본 발명의 다른 예로써, 디지털 티브이(10)에서 상기와 같은 과정을 통해 MP3 음악 파일을 전송받아 홈 네트워크에 연결된 MP3 플레이어에 전송하고, 그 MP3 플레이어에서는 수신되는 MP3 음악 파일을 즉시 재생출력하거나 내부의 메모리에 저장해 두었다가 필요시 재생 출력할 수 있다.As another example of the present invention, the digital TV 10 receives the MP3 music file through the above process and transmits it to the MP3 player connected to the home network, and the MP3 player immediately plays or outputs the received MP3 music file. It can be stored in the memory and played back when needed.
본 발명의 또 다른 예로써, 홈 네트워크에 연결된 홈네트워크기기 중 하나의 기기가 인터넷과 연결 가능한 경우, 그 인터넷을 통해 필요한 정보를 수신하여 상기와 같이 해당 홈 네트워크기기에 전송할 수 있다.As another example of the present invention, when one of the home network devices connected to the home network is able to connect with the Internet, it may receive necessary information through the Internet and transmit it to the corresponding home network device as described above.
상기와 같이 인터넷을 통해 정보를 취득하는 경우 그 정보를 디지털티브이(10)에 내장된 하드디스크나 메모리에 저장해 두고, 해당 홈네트워크기기에서는 필요시 그 정보를 전송받아 사용할 수 있다.When the information is acquired through the Internet as described above, the information is stored in a hard disk or a memory embedded in the digital device 10, and the home network device can receive and use the information if necessary.
이상에서 상세히 설명한 바와 같이 본 발명은 디지털 티브이에서 디지털 방송용 데이터와 함께 홈 네트워크 기기용 응용 데이터를 전송받아 홈 네트워크에 연결된 해당 기기에 전송하여 필요한 용도로 사용할 수 있도록 함으로써, 홈 네트워크 시스템의 사용 효율을 향상킬 수 있는 효과가 있다.As described in detail above, the present invention receives the application data for the home network device together with the digital broadcasting data from the digital TV, and transmits the data to the corresponding device connected to the home network so that it can be used for a necessary purpose. There is an effect that can be improved.
