Publication number: 20060215060Abstract: A video processing apparatus is described. The video processing apparatus includes a video decoder, a deinterlacer, a PIP (picture-in-picture) module and a PIP characteristic controller. The video decoder receives a video signal and decodes the video signal into a digital video signal. The deinterlacer receives the digital video signal and generates a non-interlacing signal. The PIP module overlaps the non-interlacing signal, in response to a PIP characteristic signal, with a screen signal and generates a PIP video that can be played by a display. The PIP characteristic controller generates the PIP characteristic signal in response to a PIP command. The PIP command comes from a computer. The deinterlacer and the PIP module are realized by hardware.Type: ApplicationFiled: July 22, 2005Publication date: September 28, 2006Inventors: Ming-Hou Dai, Wen-Chien Chang, Jui-Hsiang Yang
