Εκεί στην Consumer Technology Association (CTA) που παλαιότερα είχε την ονομασία CEA το αποφάσισαν. Και ανακοίνωσαν και το logo αλλά και…
…την ανάλύση για την εποχή της 8K Ultra HD. Οι δε κατασκευαστές θα αρχίσουν να χρησιμοποιούν το logo από το 2020 εάν τηρούν τις προδιαγραφές.
Η δε CTA έχει θέσει τις διευκρινήσεις για: display resolution, digital inputs, up-conversion και bit depth.
“CTA is home to video industry players across the ecosystem – from manufacturers to the content and entertainment sector – and we’re proud to convene such a diverse group of innovative companies to work together,” said Gary Shapiro, president & CEO, CTA. “This 8K Ultra HD definition is the product of our Video Division Board’s dedication and hard work. As a result, retailers and consumers will know products that carry the accompanying logo deliver 8K UHD quality and performance.”

Display Resolution: The display shall have at least 33 million active pixels, with at least 7680 horizontally and 4320 vertically within a 16:9 viewable window. The aspect ratio of the image shall be properly produced and not distorted. Physical pixels shall be individually addressable such that the horizontal and vertical resolution above can be demonstrated over the full range of colors provided by the display and measured in accordance with the established guidelines for measurement of visible resolution specified in version 1.03c, section 7.8, of the International Display Measurement Standard (IDMS) specified by the International Committee for Display Metrology (ICDM). Display shall meet a minimum of 50% contrast modulation using a 1×1 grill pattern.*
* – If the contrast measurement is phase dependent, the average of the measurements of the two phases shall be used for the calculation of contrast modulation as described in section 7.2 of IDMS 1.03c.
Up-conversion: The display is capable of upscaling SD, HD and 4K video and displaying it at 8K display resolution or better.
Digital Inputs: Has one or more HDMI inputs supporting the following characteristics:
– Resolution of 7680×4320 pixels.
– Bit depth of 10-bits.
– Progressive scan.
– Frame rates of 24, 30, and 60 frames per second as well as at the associated
1000/1001 fractional frame rates.
– Frame rates of 25 and 50 frames per second for displays intended for use in 50 Hz
regions.
– HDR transfer functions as specified by ITU-R BT.2100.
– RGB Colorimetry and the Non-Constant Luminance Y’C’BC’R signal format, as
specified by ITU-R BT.2100.
– At least one of the 7680×4320 HDMI inputs shall support HDCP v2.2 or equivalent
content protection.
Bit Depth: Has the capability to receive 10-bit 8K images and render an image that shows responsiveness to changes to any of the 10 bits. The exact manner of processing is not specified.
