HDR Static Metadata Extensions(HDR标准)

This standard specifies static High Dynamic Range (HDR) metadata extensions using an additional InfoFrame and EDID CTA data block, replacing previously reserved codes in Table 5 and Table 46 of CTA-861-F [1]. Recommendations regarding the usage of static HDR metadata are also provided. These data structures allow signaling of SMPTE ST 2084 HDR EOTF [2] and SMPTE ST 2086 Mastering Display Metadata [3], while containing provisions for future HDR EOTFs and metadata. It is anticipated that these data structures will be extended to include additional EOTF and HDR metadata capabilities in future versions of CTA-861-F [1]. The requirements of this standard are in addition to and complement CTA-861-F [1]. All devices compliant to CTA-861.3 shall also comply with CTA-861-F [1], except that this standard deprecates and replaces Table 5 and Table 46 of CTA-861-F [1].
