Video signal conversion device and method thereof

A video signal conversion method, comprising:

• splitting, by a splitter, an input signal sending from a video source into a first path of the input signal and a second path of the input signal, wherein the splitter is electrically coupled to the video source;
• receiving the first path of the input signal;
• extracting an image metadata from the first path of the input signal;
• determining whether the first path of 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 first video receiver supports the high dynamic range imaging format;
• in response to the first path of the input signal corresponding to the high dynamic range imaging format and the first 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 first path of the input signal generated from the splitter 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 a first video receiver;
• receiving, by the first video receiver, the output signal in SDR imaging format;
• and
• receiving, by a second video receiver, the second path of the input signal.
