In April 2018, RTL started broadcasting its own UHD channel in Germany. First available at Astra 19.2°E, the Channel shows UHD productions, Formula 1, Football and Deutschland sucht den Superstar. Satellite operator SES broadcast an 8K television signal via its satellite system for the first time in May 2018.
DVB finalized UHD-1 Phase 2 in 2016, with the introduction of service by broadcasters expected in 2017. UHD-1 Phase 2 adds features such as high dynamic range (using HLG and PQ at 10 or 12 bits), wide color gamut ( BT. 2020 / 2100 colorimetry), and high frame rate (up to 120 Hz).
These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed "Cinemascope", "21∶9" etc.), while the standard horizontal resolution, e.g. 1920 pixels, is usually kept.
This format has a resolution of 2048 × 1080 (2.2 megapixels) with an aspect ratio of 256∶135 (1.8 962) or roughly "17∶9". [11] This is the native resolution for DCI-compliant 2K digital projectors – active displays with this resolution are rare. The display aspect ratio is frequently wider than the native one, requiring non-square pixels.
Ultra HD Blu-ray (4K Ultra HD, UHD-BD, or 4K Blu-ray) [2] [3] is a digital optical disc data storage format that is an enhanced variant of Blu-ray. [4] Ultra HD Blu-ray supports 4K UHD (3840 × 2160 pixel resolution) video at frame rates up to 60 progressive frames per second, [4] encoded using High-Efficiency Video Coding. [4]

UHD Phase A covers broadcasting services to be launched by end of 2016 or early 2017. The guidelines for UHD Phase A are: [7] Display resolution of 1080p or 2160p (progressive video only); Wide color gamut (WCG) – wider than Rec. 709) (Rec. 2020 must be supported); High dynamic range (HDR) – at least 13 stops (2 13 =8192:1); Bit depth of 10 ...
Each EU contains 2 × 128-bit FPUs and has double peak performance per clock cycle compared to previous generation. One supports FP32 and FP64, and the other supports only FP32. Since the throughput of FP64 instructions are 2 cycles, the FP64 FLOPS is a quarter of the FP32 FLOPS. Only one of the FPUs supports 32-bit integer instructions.
