Last week, the Ultra HD logo for Europa was revealed, and here is the logo for the US market. US buyers should also be aware of the difference between “4K Ultra HD” and “4K Ultra HD Connected”.
Ultra HD logo for the US
The new logo makes use of the “4K” moniker, too, as it reads “4K Ultra HD”. The TV industry had originally wanted to use just Ultra HD, but TV makers such as Sony refused and continued to promote its TVs as 4K TVs.
US buyers need to be aware that two logos exist. The Connected logo is a higher-tier requirement that basically says that the TV is capable of streaming 4K content via HEVC decoding, for example from Netflix and the upcoming Amazon 4K service.
The requirements for using the “4K Ultra HD” logo are:
Display Resolution – Has at least eight million active pixels, with at least 3840 horizontally and at least 2160 vertically.
Aspect Ratio – Has a width to height ratio of the display’s native resolution of 16:9 or wider.
Upconversion – Is capable of upscaling HD video and displaying it at Ultra High-Definition resolution.
Digital Input – Has one or more HDMI inputs supporting at least 3840x2160 native content resolution at 24p, 30p and 60p frames per second. At least one of the 3840x2160 HDMI inputs shall support HDCP revision 2.2 or equivalent content protection.
Colorimetry – Processes 2160p video inputs encoded according to ITU-R BT.709 color space and may support wider colorimetry standards.
Bit Depth – Has a minimum color bit depth of eight bits.
“4K Ultra HD Connected” requires a more:
Ultra High-Definition Capability – Meets all of the requirements of the CEA Ultra High-Definition Display Characteristics V2 (listed above).
Video Codec – Decodes IP-delivered video of 3840x2160 resolution that has been compressed using HEVC* and may decode video from other standard encoders.
Audio Codec – Receives and reproduces, and/or outputs multichannel audio.
IP and Networking – Receives IP-delivered Ultra HD video through a Wi-Fi, Ethernet or other appropriate connection.
Application Services – Supports IP-delivered Ultra HD video through services or applications on the platform of the manufacturer’s choosing.
