CTA 861.3

This standard specifies static High Dynamic Range (HDR) metadata extensions using an additional InfoFrame and EDID CEA data block, replacing previously reserved codes in Table 5 and Table 46 of CEA-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 CEA-861-F [1].

The requirements of this standard are in addition to and complement CEA-861-F [1]. All devices compliant to CEA-861.3 shall also comply with CEA-861-F [1], except that this standard deprecates and replaces Table 5 and Table 46 of CEA-861-F [1].
