이렇게 구성된 도 1장치를 도 2를 참조하여 좀 더 상세히 살펴본다.The apparatus of FIG. 1 configured as above will be described in more detail with reference to FIG. 2.

도 2는 외부저장매체로 데이터를 전송하기 위한 제어흐름도이다.2 is a control flowchart for transmitting data to an external storage medium.

우선, 디지털방송수신기(10)와 데이터전송을 하기위한 외부저장매체인 PC(20)가 IEEE1394인터페이스를 사용해 데이터송수신가능하도록 연결되어 있다. 사용자는 디지털방송수신기(10)로 입력되는 데이터중 원하는 데이터를 전송하기 위해 키입력부(15)를 사용해 데이터전송모드키를 입력한다(단계 201). 그러면 디지털방송수신기(10)의 제어부(11)는 데이터전송모드키가 입력됨을 알리는 신호를 IEEE1394인터페이스(14)를 통해 PC(20)로 알려준다. PC(20)의 IEEE1394인터페이스(22)는 디지털방송수신기로부터의 데이터전송모드키가 입력됨을 알리는 신호가 입력되면, 이를 제어부(21)로 전송한다. PC(20)의 제어부(21)는 현재 연결되어 있는 저장부(23)에 저장가능한 디렉토리구조를 IEEE1394인터페이스(22)를 통해 디지털방송수신기(10)로 전송한다. 디지털방송수신기(10)의 IEEE1394인터페이스(14)가 디렉토리구조를 제어부(11)로 전송하면, 제어부(11)는 디렉토리구조를 모니터(16)에 화면출력하도록 하여 사용자에게 보여준다(단계 202). 사용자는 모니터(16)를 통해 현재 데이터를 전송하고자하는 PC(20)의 디렉토리 구조를 보고 원하는 디렉토리를 선택한다. 그러면, 디지털방송수신기(10)의 제어부(11)는 디렉토리선택키가 입력되었는지를 판단한다(단계 203). 제어부(11)는 사용자의 디렉토리선택키가 입력되었다고 판단되면, 선택된 디렉토리에 데이터가 저장되도록 데이터전송모드를 세팅한다(단계 204). 즉, 디지털방송수신기(10)의 제어부(11)는 저장할 디렉토리를 IEEE1394인터페이스(14, 22)를 통해 PC(20)의 제어부(21)에 알려주므로서 전송하는 데이터를 선택한 디렉토리에 저장하도록 패스(path)를 만든다. 이렇게 하여 데이터전송모드의 세팅이 완료된다. 이후, 사용자는 케이블이나, 튜너를 통해 수신되는 데이터를 모니터(16)를 통해 시청하면서 전송을 원하는 데이터를 선택하면 된다. 디지털방송수신기(10)의 제어부(11)는 전송을 원하는 데이터선택키가 입력되었는지를 판단한다(단계205). 제어부(11)는 판단결과 데이터선택키가 입력되지 않으면 종료하고, 데이터선택키가 입력되면, 선택된 데이터를 전송한다(단계 206). 여기서, 디지털방송수신기(10)의 제어부(11)는 사용자가 선택하는 데이터들을 데이터베이스부(13)에 데이터베이스형태로 저장한다. 이러한 과정을 거쳐서 사용자가 원하는 데이터가 PC(20)로 전송되면, PC(20)는 저장부(23)의 세팅된 디렉토리에 전송되는 데이터를 저장한다.First, the digital broadcast receiver 10 and a PC 20, which is an external storage medium for data transmission, are connected to enable data transmission and reception using the IEEE 1394 interface. The user inputs a data transmission mode key using the key input unit 15 to transmit desired data among the data input to the digital broadcast receiver 10 (step 201). Then, the control unit 11 of the digital broadcasting receiver 10 informs the PC 20 of the signal indicating that the data transmission mode key is input through the IEEE 1394 interface 14. The IEEE 1394 interface 22 of the PC 20 transmits a signal indicating that the data transmission mode key from the digital broadcast receiver is input to the control unit 21. The control unit 21 of the PC 20 transmits the directory structure that can be stored in the storage unit 23 that is currently connected to the digital broadcast receiver 10 through the IEEE 1394 interface 22. When the IEEE 1394 interface 14 of the digital broadcast receiver 10 transmits the directory structure to the control unit 11, the control unit 11 outputs the directory structure to the monitor 16 for display to the user (step 202). The user selects the desired directory by looking at the directory structure of the PC 20 to which the current data is to be transmitted through the monitor 16. Then, the control unit 11 of the digital broadcast receiver 10 determines whether the directory selection key is input (step 203). If it is determined that the user's directory selection key is input, the controller 11 sets the data transmission mode so that data is stored in the selected directory (step 204). That is, the control unit 11 of the digital broadcasting receiver 10 informs the control unit 21 of the PC 20 via the IEEE1394 interfaces 14 and 22 to store the data to be transmitted in the selected directory. path). This completes the setting of the data transfer mode. Thereafter, the user may select data to be transmitted while watching the data received through the cable or tuner through the monitor 16. The control unit 11 of the digital broadcast receiver 10 determines whether a data selection key for transmission is input (step 205). The control unit 11 ends if the data selection key is not input as a result of the determination, and transmits the selected data when the data selection key is input (step 206). Here, the control unit 11 of the digital broadcast receiver 10 stores the data selected by the user in the database unit 13 in the form of a database. When the data desired by the user is transmitted to the PC 20 through the above process, the PC 20 stores the data transmitted in the set directory of the storage unit 23.

데이터 전송이 완료된후, 사용자가 이를 다시 디지털방송수신기(10)를 사용해 시청하고자 하는 경우, 키입력부(15)를 통해 전송데이터탐색키를 입력한다. 그러면, 제어부(11)는 데이터베이스부(13)로부터 전송된 데이터의 목록을 모니터(16)에 보여주고 사용자는 원하는 데이터를 선택하면 된다. 선택한 데이터를 디지털방송수신기(10)의 모니터(16)를 통해 시청가능함은 디지탈방송수신기와 PC간 IEEE1394인터페이스를 사용하는 앞서 설명한 과정으로부터 자명하다.After the data transmission is completed, if the user wants to view it again using the digital broadcast receiver 10, the user inputs the transmission data search key through the key input unit 15. Then, the control unit 11 shows the list of data transmitted from the database unit 13 to the monitor 16 and the user can select the desired data. It is apparent from the above-described process of using the IEEE 1394 interface between the digital broadcast receiver and the PC that the selected data can be viewed through the monitor 16 of the digital broadcast receiver 10.

전술한 실시예에서는 디지털방송수신기와 외부저장매체로 PC가 연결되어 있는 것으로 설명하였으나, 외부저장매체를 여러개 연결하여 선택적으로 데이터를 전송하는 것으로도 가능하다.In the above-described embodiment, the PC is connected to the digital broadcasting receiver and the external storage medium, but it is also possible to selectively transmit data by connecting multiple external storage media.

본 발명은 디지털방송수신기를 외부저장매체와 연결하여 데이터를 전송하므로, 외부저장매체를 보다 효율적으로 사용할 수 있으며, 디지털방송수신기로 수신되는 방대한 양의 데이터의 활용성을 높이는 효과를 제공한다.Since the present invention connects a digital broadcast receiver with an external storage medium to transmit data, the external broadcast medium can be used more efficiently and provides an effect of increasing the utilization of a large amount of data received by the digital broadcast receiver.
