HDR10 is a standard adopted widely by most global monitor brands, as many major companies have implemented the HDR10 protocol. Defined jointly by the Blu-Ray Association, HDMI Forum, and UHD Association, HDR10 supports the compressed transmission of HDR video content. HDR10 was officially defined as a format that supports HDR content by the Consumer Electronics Association (CEA) on August 27, 2015. One of the key factors to fulfill HDR requirements on a monitor is the ability to decode files in the HDR10 format.
HDR10 files need to meet the following criteria:
1. EOTF (electro-optical transfer function) using SMPTE ST2084
2. Color sub-sampling: 4:2:2/4:2:0 (for compressed video sources)
3. Bit depth: 10-bit
4. Primary color: ITU-R BT.2020
5. Metadata: SMPTE ST2086, MaxFALL, MaxCLL
**SMPTE ST2086 "Mastering Display Color Volume" static metadata sends color calibration data from the mastering display, such as MaxFALL (Maximum Frame Average Light Level) and MaxCLL (Maximum Content Light Level) static values, encoded as SEI messages within the video stream.
