CEA Releases Compatibility Guidelines for High Dynamic Range Displays

The industry definition for HDR displays has been revealed.  

The Consumer Electronics Association has announced their compatibility guidelines for high dynamic range displays. The new designation is designed to help customers and retailers recognize products that are capable of handling HDR content. 

"HDR provides a significant step-up in delivering an incredible viewing experience for the consumer," said 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."

High dynamic range TVs, monitors, and projectors are able to display content with greater levels of brightness and shadow detail, bringing out highlights with superior contrast. In order to qualify under the CEA definition for HDR compatibility, a display must meet these guidelines:

• 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* 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
  
• Color 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 
  

In addition to their new HDR guidelines, the Consumer Electronics Association has also done extensive work to help designate 4K Ultra HD products with their own requirements and logos.
