Patent number: 11095828Abstract: A video signal conversion device includes a front end interface, a rear end interface, a video detector and a video processor. The front end interface is coupled to a video source to receive an input signal. The rear end interface is coupled to a video receiver. The video detector determines whether the input signal corresponds to HDR imaging format. The video detector generates a conversion command in response to the input signal corresponding to HDR imaging format. The video processor is coupled to the front end interface, the rear end interface and the video detector. When the video processor receives the conversion command, the video processor converts the input signal into an output signal with SDR imaging format. The video processor sends the output signal to the video receiver via the rear end interface.Type: GrantFiled: April 2, 2019Date of Patent: August 17, 2021Assignee: AVerMedia TECHNOLOGIES, INC.Inventors: Wen-Chien Chang, Yen-Cheng Yao

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
