4K resolution
The term "2160p" could be applied to any format with a height of 2160 pixels, but it is most commonly used in reference to the 4K UHDTV resolution of 38402160 due to its association with the well-known 720p and 1080p HDTV formats. Although 38402160 is both a 4K resolution and a 2160p resolution, these terms cannot always be used interchangeably since not all 4K resolutions are 2160 pixels tall, and not all 2160p resolutions are ≈4000 pixels wide. However, some companies have begun using the term "4K" to describe devices with support for a 2160p resolution, even if it is not close to 4000 pixels wide. For example, many "4K" dash cams only support a resolution of 28802160 (4∶3); although this is a 2160p resolution, it is not a 4K resolution. Samsung also released a 51202160 (64∶27) TV, but marketed it as a "4K" TV despite its 5K-class resolution.
SES S.A.
In May 2018 SES broadcast an 8K television signal via its satellite system for the first time, as part of its Industry Days conference at the Luxembourg HQ. The 8K demonstration content, with a resolution of 7680x4320 pixels, a frame rate of 60 frames per second and 10-bit colour depth, was encoded in HEVC and transmitted at a rate of 80 Mbit/s via the Astra 3B satellite.
