HDR-Compatible Gets An Official Definition

Ever heard the term HDR-compatible? Ever wonder what that exactly means? Well, wonder no more! The Consumer Electronics Association (CEA) has finally announced an industry definition for an HDR-compatible device. HDR is but one element of the fast-growing 4K Ultra HD display devices, which allow for increased range of brightness and contrast. The CEA partnered with manufacturers, content providers, and distributors in order to develop the list of voluntary guidelines in an attempt to make it simpler for retailers and consumers to identify HDR-compatible displays. Even though no official HDR logo was announced, it is expected that there will be one in the near future.

The CEA announced that the industry definition for HDR (High Dynamic Range) compatible video displays. This new designation is designed to assist retailers and consumers in identifying products that incorporate this interface and processing technology. HDR promises to deliver an expansive range of brightness and shadow detail, which further enhances the viewing experience.

According to the CEA, "HDR provides a significant step up in delivering an incredible viewing experience for the consumer." Senior Vice President of Research and Standards for the CEA Brian Markwalter added, "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."

Many 4K Ultra HD devices will include early implementations of various next-generation technologies, which includes HDR, wider color gamut, and higher frame rates. This provides a more realistic and immersive viewing experience. The following definition was approved by the CEA's video division board:


A TV, monitor or projector may be referred to as an HDR-compatible Display if it meets the following minimum attributes:

• Includes at least one interface that supports HDR signaling 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* (see below) 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.

"CEA's leading role in defining HDR-compatible displays complements the work of other organizations, such as the UHD Alliance, that are reportedly developing HDR-related performance parameters and guidance for the video content, distribution and hardware ecosystem," Markwalter added.
