FIELD: telecommunications.
SUBSTANCE: invention relates to ultra high definition (UHD) video signal transmitting and receiving device and method. Disclosed is signal transmission/reception method and device, wherein method is compatible with existing bit depth 8-bit mode based on high-definition (HD) with supporting of bit depth 10-bit mode based on UHD, and includes: video data multiplexing or reverse multiplexing, which can be displayed in any bit depth colour gamma from plurality of bit depths, and signalling information, relating to displaying, so, that displaying is performed in any bit depth colour gamma from plurality of bit depths; and multiplexed or back multiplexed video data and signalling information processing.
EFFECT: technical result is enabling possibility of video signal displaying, having different bit depths, according to receiver operating characteristics.
