The usage of this information can be employed by the display to adapt the delivered HDR imagery to the capability of the display device. The inform
20、ation conveyed in the SEI message carrying SMPTE ST 2094-10 4 HDR dynamic metadata is adequate for purposes corresponding to the use of Society of Motion Picture and Television Engineers SMPTE ST 2094-1 3 “Dynamic Metadata for Color Volume Transform - Core Components“ and SMPTE ST 2094-10 4 “Dynamic
