A video signal conversion method includes: receiving an input signal from a video source; extracting an image metadata from the input signal; determining whether the input signal corresponds to a high dynamic range (HDR) imaging format according to at least one format information of the image metadata and determining whether a video receiver supports the high dynamic range imaging format; in response to the input signal corresponding to the high dynamic range imaging format and the video receiver being not support the high dynamic range imaging format, generating a conversion command; receiving, by a video processor, the conversion command; converting, by the video processor, the input signal into an output signal corresponding to a standard dynamic range (SDR) imaging format according to the conversion command; sending, by the video processor, the output signal to the video receiver; and receiving by the video receiver, the output signal in SDR imaging format.

Video signal conversion device and method thereof

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.

A video signal processing apparatus and a computer system integrated with the video signal processing apparatus are disclosed. The video signal processing apparatus has a tuner, a video processor, a non-interlaced signal processing unit, a microprocessor, and a computer signal converter. In the video signal processing apparatus, the display can be instantly turned on and the video signal can be recorded in the storage media of a computer, and the video signal recorded in the storage media can be displayed on the display. While watching the video signal on the display, a user can execute applications in the computer simultaneously. The video signal processing apparatus further provides picture-in-picture feature by adding another set of tuner and video processor. The video signal processing apparatus can be integrated with a display or a computer, and can also be used as an external-enclosure video signal processing apparatus.
