The Consumer Electronics Association (CEA) announces the industry definition for high dynamic range (HDR)-compatible displays, a means for HD and 4K/UHD displays to push brighter, more colourful pixels.
Such a definition should make it easier for retailers and customers to determine whether a display carries the interface and processing technology required to produce HDR content. Many 4K/UHD sets already support early HDR implementations through wider colour gamuts and higher frame rates.
According to the Association, an HDR-compatible TV, monitor or projector should have the following minimum attributes:
- Includes at least one interface with HDR signaling support (as defined in CEA-861-F, extended by CEA-861.3).
- Receives and processes static CEA-861.3-compliant HDR metadata for uncompressed video.
- Receives and processes HDR10 Media Profile from IP, HDMI or other video delivery sources.
- Applies an appropriate Electro-Optical Transfer Function (EOTF) before rendering images.
The HDR interoperability guidelines build on earlier CEA work on 4K/UHD technology. The association will also help retailers through promotional efforts covering the new technology.
“HDR provides a significant step-up in delivering an incredible viewing experience for the consumer,” the CEA says. “We encourage manufacturers and our industry partners to use this voluntary compatibility guideline to provide greater consistency and clarity while ensuring compatibility and interoperability across the full content development to display ecosystem.”
