다만, 디지털 방송수신장치(100) 내에 포함될 수 있는 기타의 구성요소는 도면에서 배제하고 본 발명을 설명함에 있어 필요한 구성요소만을 도시하는 것으로 한다.However, other components that may be included in the digital broadcast receiving apparatus 100 are excluded from the drawings and only those components necessary for describing the present invention will be illustrated.

플래시 메모리(120)에는 DTV구동프로그램(122)과 GUI구동프로그램(124)이 저장되어 있다. DTV구동프로그램(122)은 방송화면을 재생하는데 이용되는 프로그램이고, GUI구동프로그램(124)은 그래픽데이터를 디스플레이하는데 이용되는 프로그램이다.The flash memory 120 stores the DTV driving program 122 and the GUI driving program 124. The DTV drive program 122 is a program used to reproduce the broadcast screen, and the GUI drive program 124 is a program used to display graphic data.

또한, 플래시 메모리(120)는 소정 시간분량(예를들면, '3시간')의 방송이 선입선출(FIFO : First-In First-Out)방식에 따라 저장가능하다.In addition, the flash memory 120 may store a predetermined amount of time (eg, '3 hours') of broadcasting in a first-in first-out (FIFO) manner.

방송신호 수신부(130)는 제어부(110)의 제어에 따라 외부장치(예를들면, 외부셋탑박스, 외부TV 등)나 튜너로부터 방송신호를 수신하고, 수신한 방송신호를 신호처리부(140)로 인가한다.The broadcast signal receiver 130 receives a broadcast signal from an external device (for example, an external set-top box, an external TV, etc.) or a tuner under the control of the controller 110, and transmits the received broadcast signal to the signal processor 140. Is authorized.

신호처리부(140)는 방송신호 수신부(130)가 수신한 방송신호를 처리하여 재생될 방송화면으로 처리한다.The signal processor 140 processes the broadcast signal received by the broadcast signal receiver 130 into a broadcast screen to be reproduced.

GUI처리부(150)는 GUI구동프로그램(124)에 의해 로딩된 그래픽데이터를 방송화면에 오버랩 처리한다. 구체적으로, GUI처리부(150)는 방송화면상에 그래픽데이 터로 구성된 초기메뉴가 중첩하여 디스플레이될 수 있도록, 그래픽데이터를 처리한다.The GUI processor 150 overlaps the graphic data loaded by the GUI driver 124 on the broadcast screen. Specifically, the GUI processor 150 processes graphic data so that an initial menu composed of graphic data may be superimposed and displayed on the broadcast screen.

디스플레이 구동부(160)는 방송화면과 그래픽데이터를 디스플레이 되도록 구동시킨다.The display driver 160 drives the broadcast screen and the graphic data to be displayed.

디스플레이부(170)에는 구동된 방송화면과 그래픽데이터가 디스플레이된다.The display unit 170 displays the driven broadcast screen and graphic data.

제어부(110)는 플래시 메모리(120)에 저장되어 있는 DTV구동프로그램(122)을 로딩하고, 로딩된 DTV구동프로그램(122)을 이용하여 방송신호 수신부(130)를 제어하여 방송화면이 재생되도록 한다.The controller 110 loads the DTV drive program 122 stored in the flash memory 120 and controls the broadcast signal receiver 130 using the loaded DTV drive program 122 to reproduce the broadcast screen. .

제어부(110)는 플레시 메모리(120)에 저장되어 있는 GUI구동프로그램(124)을 로딩하고, 로딩된 GUI처리부(150)가 그래픽데이터를 처리하여 배너형식의 초기메뉴형태로 방송화면상에 디스플레이되게 한다. The controller 110 loads the GUI driving program 124 stored in the flash memory 120, and the loaded GUI processing unit 150 processes graphic data to be displayed on the broadcast screen in the form of a banner initial menu. do.

이와 같은 로딩 방식에 의해, 데이터량이 적은 DTV구동프로그램(122)을 먼저 로딩되어, 방송화면이 재생된 후에 GUI구동프로그램(124)을 로딩함으로써, 디지털 방송수신장치(100)의 시청시작시간이 빨라진다.By such a loading method, the DTV driving program 122 having a small amount of data is loaded first, and then the GUI driving program 124 is loaded after the broadcast screen is played, so that the viewing start time of the digital broadcasting receiver 100 is increased. .

도 2는 본 발명의 일 실시예에 따른 디지털 방송수신장치의 구동방법에 관한 흐름도이다.2 is a flowchart illustrating a method of driving a digital broadcast receiver according to an embodiment of the present invention.

도 1 및 도 2를 참조하면, 제어부(110)의 제어하에 DTV구동프로그램(122)이 우선 로딩되면(S210), 방송신호가 수신되어 방송화면이 재생된다(S220).1 and 2, when the DTV driving program 122 is first loaded under the control of the controller 110 (S210), a broadcast signal is received and a broadcast screen is reproduced (S220).

구체적으로, 제어부(110)가 DTV구동프로그램(122)을 로딩하면, 방송신호 수신부(130)는 방송신호를 수신하여 신호처리부(140)로 전달한다. 신호처리부(140)가 방송신호 수신부(130)로부터 전달받은 방송신호를 처리하여 방송화면으로 변환하면, 변환된 방송화면이 디스플레이 구동부(160)에 의해 구동되어 디스플레이부(170) 상에서 재생된다.In detail, when the controller 110 loads the DTV driving program 122, the broadcast signal receiver 130 receives the broadcast signal and transmits it to the signal processor 140. When the signal processor 140 processes the broadcast signal received from the broadcast signal receiver 130 and converts the broadcast signal into a broadcast screen, the converted broadcast screen is driven by the display driver 160 to be reproduced on the display 170.

여기서, 제어부(110)가 TV구동프로그램(122)을 먼저 로딩하는 이유는 그래픽데이터보다 데이터량이 적은 방송수신데이터가 먼저 로딩되게하여, 부팅시간을 단축하기 위해서이다.The reason why the controller 110 loads the TV driving program 122 first is to reduce the booting time by loading broadcast receiving data having a smaller data amount than the graphic data first.

이에 의해 사용자는 보다 빠르게 방송화면을 볼 수 있다.As a result, the user can view the broadcast screen more quickly.

DTV구동프로그램(122)이 로딩된 후에 제어부(110)가 GUI구동프로그램(124)을 로딩하면(S230), 그래픽데이터로 된 초기메뉴가 디스플레이부(170) 상에 방송화면과 중첩되어 표시된다(S240).If the control unit 110 loads the GUI driving program 124 after the DTV driving program 122 is loaded (S230), an initial menu of graphic data is displayed on the display unit 170 so as to overlap with the broadcast screen ( S240).

구체적으로, 제어부(110)가 GUI구동프로그램(124)을 로딩하면, GUI처리부(150)가 그래픽데이터를 처리하여 초기메뉴를 형성하고, 형성된 그래픽데이터 초기메뉴는 디스플레이 구동부(160)를 통해 디스플레이부(170) 상에 표시된다. 디스플레이부(170) 상에 표시되는 그래픽데이터는 배너(banner)형식으로 처리되고, 방송화면에 중첩되어 표시된다.Specifically, when the controller 110 loads the GUI driving program 124, the GUI processor 150 processes graphic data to form an initial menu, and the formed graphic data initial menu is displayed through the display driver 160. Is displayed on 170. The graphic data displayed on the display unit 170 is processed in a banner form and is superimposed on the broadcast screen.

여기서, 그래픽데이터 중에서도, 채널과 같이 필수적인 그래픽데이터부터 먼저 로딩하고, 그 후에 나머지 그래픽데이터를 로딩하여 부팅시간을 보다 단축시킨다.Here, among the graphic data, the essential graphic data such as a channel is loaded first, and then the remaining graphic data is loaded first to further shorten the booting time.

또한, 로딩 전에 있는 그래픽데이터 중에서 소정의 그래픽데이터가 우선적으로 필요할 때, 해당 어드레스로 가서 소정의 그래픽데이터를 우선 로딩한다.In addition, when predetermined graphic data is preferentially needed among the graphic data before loading, it goes to the address and loads predetermined graphic data first.

이상에서 설명한 바와 같이, 본 발명에 따르면, 디지털 방송수신장치 및 그의 구동방법에 있어서, 어플리케이션을 DTV구동프로그램과 GUI구동프로그램으로 분리하여, 데이터량이 적은 DTV구동프로그램을 먼저 로딩하여 방송화면이 재생되게 하고, DTV구동프로그램이 로딩된 후에 GUI구동프로그램을 로딩하여 그래픽데이터가 디스플레이 되게 함으로써, 디지털 방송수신장치의 부팅시간이 단축되는 효과가 있다. As described above, according to the present invention, in the digital broadcasting receiver and its driving method, the application is divided into a DTV driving program and a GUI driving program, so that a DTV driving program having a small amount of data is loaded first so that a broadcast screen is played. After loading the DTV driving program, the GUI driving program is loaded to display the graphic data, thereby reducing the booting time of the digital broadcasting receiver.

또한, 이상에서는 본 발명의 바람직한 실시 예에 대하여 도시하고 설명하였지만, 본 발명은 상술한 특정의 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진자에 의해 다양한 변형실시가 가능한 것은 물론이고, 이러한 변형실시들은 본 발명의 기술적 사상이나 전망으로부터 개별적으로 이해되어 저서는 안 될 것이다.In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the above-described specific embodiment, the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and such modifications should not be individually understood from the technical spirit or the prospect of the present invention.
