위와같은 목적을 달성하기 위한 본 발명의 특징은 OSD데이타의 밝기를 자동으로 조절하는 디지털방송수신기에 있어서, 디스플레이부, 수신된 디지털 영상신호를 비디오데이타, 오디오데이타 및 기타 데이터로 분리하는 디멀티플렉서, 상기 디멀티플렉서에서 분리된 비디오데이타 및 오디오데이타를 디코딩하고, 메모리로부터 인가되는 한 화상데이타를 출력하는 MPEG디코더, 상기 디코딩된 비디오데이타와 오디오데이타 및 OSD데이타를 저장하며, 입력되는 화면구성정보에 따라 비디오데이타와 OSD데이타를 한 화상으로 구성하여 출력하는 메모리 및 OSD데이타를 상기 메모리에 제공하며, 상기 구성된 화상데이타중에서 OSD데이타에 대응하는 부분의 화상데이타의 밝기정보를 검출하고, 검출된 밝기정보에 근거하여 상기 메모리에 저장된 OSD데이타의 밝기를 조절하여 상기 디스플레이부에 표시되도록 하는 제어부를 포함하는 디지털방송수신기에 있다.Features of the present invention for achieving the above object is a digital broadcast receiver for automatically adjusting the brightness of the OSD data, the display unit, a demultiplexer for separating the received digital video signal into video data, audio data and other data, the An MPEG decoder which decodes the separated video data and audio data from the demultiplexer, outputs image data applied from memory, stores the decoded video data, audio data, and OSD data, and stores the video data according to the input screen configuration information. And a memory for displaying and outputting the OSD data as one image and the OSD data to the memory, detecting brightness information of the image data of the portion of the configured image data corresponding to the OSD data, and detecting the brightness information based on the detected brightness information. Brightness of OSD Data Stored in the Memory There is a digital broadcast receiver comprising a control unit to adjust the display on the display.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 일 실시예를 상세히 설명하겠다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명의 바람직한 실시예에 따른 OSD데이타의 밝기를 자동으로 조절하는 기능을 구비한 디지털 텔레비젼 세트를 보여주는 도면이다.2 is a diagram showing a digital television set having a function of automatically adjusting brightness of OSD data according to a preferred embodiment of the present invention.
디멀티플렉서(DEMUX)(21)는 수신된 디지털신호를 비디오데이타, 오디오데이타 및 기타 데이터로 분리한다. MPEG디코더(23)는 분리된 비디오데이타 및 오디오데이타를 디코딩하여 메모리(24)로 출력한다. 이 메모리(24)에는 비디오데이타와 오디오데이타 및 OSD데이타를 저장하기 위한 영역이 분리되어 있으며, 제어부(22)로부터 입력되는 화면구성정보에 따라 비디오데이타와 OSD데이타를 한 화상으로 구성한다. 제어부(22)는 OSD발생기를 구비하며, OSD발생기에서 발생된 OSD데이타를 메모리(24)로 제공한다. 제어부(22)는 구성된 화상데이타중 OSD데이타에 대응하는 부분의 화상데이타의 밝기정보를 검출한다. 제어부(22)는 검출된 밝기정보에 근거하여 OSD데이타의 밝기를 조절한다. 즉, 종래에는 화면이 밝을 경우 흰색의 OSD데이타가 잘 보이지 않았지만, 본 발명은 화면이 밝을 경우 OSD데이타를 어둡게 하여 흰색의 OSD데이타가 잘 보이도록 한다. 또한, 화면이 어두울 경우에는 OSD데이타를 밝게하여 검은색의 OSD데이타가 잘 보이도록 한다.The demultiplexer (DEMUX) 21 separates the received digital signal into video data, audio data and other data. The MPEG decoder 23 decodes the separated video data and the audio data and outputs them to the memory 24. The memory 24 has separate areas for storing video data, audio data, and OSD data, and constitutes one image of the video data and the OSD data according to the screen configuration information input from the control unit 22. The controller 22 includes an OSD generator, and provides OSD data generated by the OSD generator to the memory 24. The controller 22 detects brightness information of the image data of the portion of the configured image data corresponding to the OSD data. The controller 22 adjusts the brightness of the OSD data based on the detected brightness information. That is, in the related art, when the screen is bright, the white OSD data is hardly seen, but the present invention makes the OSD data of the white visible by darkening the OSD data when the screen is bright. In addition, when the screen is dark, the OSD data is brightened so that the black OSD data is easily seen.
메모리(24)는 화상데이타 및 화상데이타에 알맞은 밝기로 조절된 OSD데이타를 MPEG디코더(23)로 출력한다. MPEG디코더(23)는 한 화상데이타를 NTSC/PAL 디코더(25)로 출력한다. NTSC/PAL디코더(25)는 디지털로 처리된 화상데이타를 아날로그신호로 변환하여 디스플레이부(26)로 출력한다. 여기서, NTSC/PAL디코더(25)는 디지털로 수신된 신호를 아날로그로 변환하여 디스플레이하기 위해 필요한 디코더로서 디지털텔레비젼에서는 반드시 필요로 하지는 않다.The memory 24 outputs the image data and the OSD data adjusted to the brightness suitable for the image data to the MPEG decoder 23. The MPEG decoder 23 outputs one picture data to the NTSC / PAL decoder 25. The NTSC / PAL decoder 25 converts digitally processed image data into an analog signal and outputs it to the display unit 26. Here, the NTSC / PAL decoder 25 is a decoder necessary to convert a digitally received signal into an analog and display the analog signal, which is not necessarily required in a digital television.
상술한 바와같이, 본 발명에 따른 OSD데이타의 밝기를 자동으로 조절하는 기능은 상술한 유럽향 디지털 텔레비젼 세트 뿐만 아니라 디지털 텔레비젼 세트에 적용될 수 있으며, MPEG화면의 밝기에 따라 OSD데이타의 밝기를 자동으로 조절함으로써 항상 선명한 OSD데이타를 볼 수 있는 효과가 있다.As described above, the function of automatically adjusting the brightness of the OSD data according to the present invention can be applied to not only the European digital TV set described above but also the digital TV set, and automatically adjusts the brightness of the OSD data according to the brightness of the MPEG screen. By adjusting it, you can always see clear OSD data.
