See Appendix A for the list.

The technical differences between this document and ITU-RBT.2100-2.2018 and their reasons are as follows.

--- Deleted 30Hz, 30/1.001Hz, 25Hz, 24Hz and 24/1.001Hz frame rates in ITU-RBT.2100-2.2018,

To adapt to my country's TV system and application needs (see Table 1 of ITU-RBT.2100-2.2018);

--- Replaced the normative reference document ITU-RBT.814 (see Table 3) with GY/T 326-2019, which was modified to adopt international standards;

--- Table 1~Table 3, Table 6~Table 9 have added the requirement type clauses that meet the corresponding table;

---The references in Table 4, Table 5, and Table 10 are modified to requirement-type clauses.

The following editorial changes have been made to this document.

--- In order to be consistent with my country's technical standard system, the standard name is changed to "High Dynamic Range TV Program Production and Exchange Image Parameter Values";

--- Deleted the "scope" and "keywords" of ITU-RBT.2100-2.2018;

--- Added a note for the description of "CIE1931XYZ color space" in Table 2;

--- Added references.
