Claim 13:
14. A video signal conversion method, comprising:
receiving a first path of an 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;
generating a conversion command 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;
converting, by a video processor, the first path of the input signal into an output signal corresponding to a standard dynamic range (SDR) imaging format according to the conversion command which is received by the video processor;

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, a second path of the input signal while the first video receiver receives the output signal in SDR imaging format,
wherein determining whether the first path of the input signal corresponds to the high dynamic range imaging format according to the at least one format information of the image metadata and determining whether the first video receiver supports the high dynamic range imaging format and generating the conversion command 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 comprise:
determining whether the first path of the input signal corresponds to the high dynamic range imaging format according to the at least one format information of the image metadata to generate a first determination;
determining whether the first video receiver supports the high dynamic range imaging format to generate a second determination; and
in response to the first determination of the first path of the input signal corresponding to the high dynamic range imaging format and the second determination of the first video receiver being not support the high dynamic range imaging format, generating the conversion command.
