Claims7
A display device for simultaneously receiving digital and analog display signal and displaying a television program corresponding to one of the signals on a display panel, the display device comprising:
- a digital tuner for inputting and performing a digital demodulation process on the digital display signal so as to output a digital video signal;
- an ADC (analog/digital converter) for performing a digitizing process on the digital video signal and outputting a digital image signal;
- an analog tuner for inputting and performing an analog demodulation process on the analog display signal so as to output an analog image signal;
- a video decoder for performing a video decoding process on the image signals and then outputting an interlaced image signal;
- a de-interlacer for performing a de-interlace process on the interlaced image signal to output a de-interlaced image signal;
- a scaler for inputting the de-interlaced image signal and performing an up-scaling/down-scaling process and outputting a television image;
- a display panel;
- and
- a display driver for driving the display panel according to the television image so as to display the television program on the display panel.
