The term ultra-high definition or UHD denotes several different standard resolutions for video creation, reproduction and broadcasting. In Switzerland, the term UHD is typically used to denote a video resolution of 3840 x 2160 pixels. This UHD format is also referred to as 4K UHD.
The high resolution of UHD video allows for high quality picture, even on large screens. Not only does UHD provide higher-resolution video than standard definition (based on the PAL, SECAM or NTSC formats) and high definition (HD) standards, it also delivers greater levels of contrast. Thanks to high dynamic range (HDR) technology, the color range of UHD video is also significantly broader than that of its predecessors.
Although public Swiss television broadcasters do not currently broadcast in UHD, some Swiss TV plans include UHD channels as part of ongoing tests. Some streaming services like Netflix offer movies and series in UHD. A UHD-compatible TV console is required in order to watch UHD broadcasts and streams on your television. A UHD-compatible television set is also required.
