The multi-industry 8K Association (8KA) has updated the performance specification for its Certified mark program, the group announced.

The updated specification now adds new decoding requirements, new image quality metrics and a game mode to stay in-line with evolving 8K features and experiences.

The 8KA’s Certification programs allow 8K TVs and other 8K-capable products to carry its authorized Certification Logo, to help consumers quickly identify products that perform to certain base levels of resolution, color and luminance performance while supporting various standards for content production and delivery. The program was developed with the intention that it can continually be updated and expanded to keep pace with the evolution of 8K technology and standards.

At the same time, the group announced that its membership expanded over the second half of 2021 to include: Amazon’s streaming platform Prime Video; S. Korean-based content creation company 4by4; product testing service UL, and the return to the organization of China-based TV maker Changhong.

The 8KA said it has Certified more than 80 TV models to date, assuring levels of resolution, luminance, color and connectivity standards on products that carry the 8K Association Certified logo.

Going forward, the program is being adapted to accept “a broader set of video decoding standards that will promote the wider availability of 8K streaming content,” the Association announcement said.

The Association said it is also expanding Certification criteria for products by embracing “Ambient Contrast Ratio (ACR)” as an additional measurable performance metric to help consumers ensure at display will sustain good picture quality performance under changing ambient light conditions.

Citing the benefit of using the new Ambient Contrast Room criteria, the 8KA saod that when a viewing room is dark a TV will be able to deliver the brightest colors and widest contrast. But as the ambient illumination increases, both of these picture quality elements diminish.

“This can be overcome with brighter TVs and TV screen technology with lower reflectance. The 8KA ACR test measures the reflectivity of the TV with a test pattern in both bright and dim illumination conditions and sets levels for performance in each case that the TV must pass. ACR is an important factor for TVs from the users’ perspective, regardless of resolution,” according to the Certification update statement.

“We have been discussing ACR more than a year as a new item and it was finally included in V2.1.0”, KG Lee, Chair of the Technology Work Group, stated. “While passing the ACR spec is optional now for certification, members are required to provide the data so we can optimize the pass/fail criteria for a future mandatory requirement.”

“Using ACR as a metric allows us to better manage the experience of viewers in different ambient light conditions that we all have in the home, added Pete Sellar, Chair of the Certification Work Group in the 8KA. “These and other efforts we are putting into developing of Certified Specification should give consumers confidence that 8K Certified TVs support the latest developments in TV viewing.”

The 8KA said it has also revised its specification with new Gaming mode requirements that include support for Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) via the HDMI 2.1 interface. This was done, the Association said, because “gaming on 8K TVs is expected to be an important use case so the 8K Association wants to help ensure the best performance.”

In related news, the 8KA said that UL (Underwriter Laboratory) is now being audited to become an 8KA certified test laboratory to measure 8K TVs for the Association’s certified logo program. Underwriter Laboratory offers a wide range of testing services to verify product safety and other purposes. The 8KA said UL will join two other labs already certified for the 8KA testing: Allion Labs and Telecommunications Technology Associates (TTA). Together, these three labs offer testing services in various regions of the world to give TV manufacturers greater options in having their TVs certified.

Concerning some of the 8KA’s more recent members, Korea-based 4by4 is a visual technology company that has produced 8K demo and promotional videos and manages the KEYCUTstock platform to license video clips up to 8K in resolution. 4by4 also has an AI-based deep learning solution named PIXELL, which enhances video quality from HD up to 8K. KEYCUTstock platform uses the Pixell solution to produce 8K video content from the raw video data for advertising companies, broadcasting companies, the 8KA stated.

“We have worked with some content creators to produce 8K video contents from the raw video data and have verified the quality of 8K video content on 8K TVs,” said Junho Yoon, CEO. “4by4 would like to share the experience with other 8KA member companies and help educate other content creators on the benefits of 8K. We are even looking at creating 8K versions of older classic Korean dramas for OTT distribution.”
