CEA boosts HDR with official definition
| 29 August 2015
The market impetus behind the high dynamic range standard has increased further and significantly after the US Consumer Electronics Association (CEA) announced an industry definition for HDR-compatible displays.
The technology trade association representing the $285 billion US consumer electronics industry believes that HDR is a new capability that promises to deliver an expansive range of brightness and shadow detail, further enhancing the viewing experience, making images appear more vivid, rich and more life-like. Only days ago Amazon revealed that it would begin offering HDR-compatible content such as blockbuster films, TV shows and Amazon Original series to its Amazon Prime members in 4K/Ultra HD over the coming months.
The CEA’s Video Division Board approved the definition as: a TV, monitor or projector may be referred to as a HDR Compatible Display if it meets the following minimum attributes: it 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; it applies an appropriate Electro-Optical Transfer Function (EOTF), before rendering the image.
The CEA is confident that by paving the way for the introduction of HDR-compatible displays, the new CEA designation is designed to assist retailers and consumers in identifying display products that incorporate the interface and processing technology needed to display the new content properly. CEA and its display manufacturer members collaborated with leading content providers and distributors as well as other technology companies to establish the new display characteristics for HDR interoperability.
“HDR provides a significant step-up in delivering an incredible viewing experience for the consumer,” remarked Brian Markwalter, senior vice president, research and standards, CEA. “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. The CEA’s leading role in defining HDR compatible displays complements the work of other organisations such as the UHD Alliance that are reportedly developing HDR-related performance parameters and guidance for the video content, distribution and hardware ecosystem.”
