8K Association announces performance specifications for 8K TVs
A recent announcement by the 8K Association has defined a selection of performance criteria as key attributes for a TV to meet in order to best present the 8K format.
The 8K Association are a cross-industry body whose remit is to promote 8K TVs and content and to develop and communicate the 8K technical ecosystem, which is precisely what they have started to do here.

The newly released technical guidelines include specifications for 8K input parameters (such as bit depth, frame rate, chroma sub-sampling), display performance (including resolution, peak brightness, black level, colour gamut, white point) and interface and media formats. A brief list was issued, as follows:

  • Resolution: 7680 x 4320 pixels
  • Input Frame Rate: 24p, 30p and 60p frames per second
  • Display Luminance: More than 600 nits peak luminance
  • Codec: HEVC
  • Interface: HDMI 2.1
  • Additional performance and interface specifications (available to members)

These performance criteria were created by the Association’s membership and interestingly appears to exclude 8K TVs which only feature HDMI 2.0, where video is limited to 8K 30Hz rather than the 8K 60Hz of HDMI 2.1. Additionally, a more efficient and effective codec for 8K video compression is being developed so the current HEVC codec listed in the guidelines may well be superseded.

With the newly released parameters recommending performance levels for HDR, colour space capabilities and interface requirements, the next goal is a transparent compliance testing regime which will enable manufacturers to have their TV sets certified as 8K approved. An acknowledged 8K badge on a member’s TV guaranteeing that the technical standards for 8K have been met or exceeded will remove public confusion and give the consumer confidence in their purchase.

8KA Executive Director, Chris Chinnock, explained, “Defining the key attributes for an 8K TV specification demonstrates the 8KA’s focus to quickly define a critical step in the growth in next-generation video technology.” He added, “To reach this milestone is a great testament to the cooperative spirit the members of the 8K Association enjoy along with our shared enthusiasm for the 8K ecosystem expansion.”

8K is the latest step up in high-resolution content creation and distribution and features 33 million pixels of resolution which enables 4 times the clarity of the 4K UHD standard.

The 8K Association’s membership includes TV manufacturers Panasonic, Samsung, Hisense and TCL. It continues to grow with members across the broadcast, content and technical service provision spectrum including companies providing television chipset technology, audio and video technology and video entertainment creators. The 8K Association now boasts 16 members, though noticeably absent are LG and Sony, both of whom have 8K TVs available.


What do members think of industry bodies dictating standards and certifying products? Does it cause homogenisation or help consumers navigate rapidly changing technology.
