The CEA has released an industry definition for displays compatible with high dynamic range (HDR) standards. The new designation, formally known as HDR-Compatible Displays, is intended to assist both retailers and consumers in identifying display products that support the interfaces and processing technology required to show HDR content.
A TV, monitor or projector is an HDR-Compatible Display if it meets the following attributes, as a minimum:
- Includes at least one interface that supports HDR signalling, as defined in CEA-861-F, as extended by CEA-861.3;
- Receives and processes static HDR metadata compliant with CEA-861.3 for uncompressed video;
- Receives and processes HDR10 Media Profile* from IP, HDMI or other video delivery sources. Additionally, other media profiles may be supported;
- Applies an appropriate Electro-Optical Transfer Function (EOTF), before rendering the image.
* HDR10 Media Profile is defined as:
- EOTF: SMPTE ST 2084;
- Colour sub-sampling: 4:2:0 (for compressed video sources);
- Bit Depth: 10-bit;
- Color Primaries: ITU-R BT.2020;
- Metadata: SMPTE ST 2086, MaxFALL, MaxCLL.
It will be interesting to see if this move is adopted for sets sold outside the US. In Europe, Digital Europe has had some success in the past with the HD Ready logo, but it wasn’t clear at press time if the organisation was going to do something for HDR. It took a long time to come to agreement on an UltraHD logo.
