UHD TV (Ultra High Definition Television)
UHD TV (Ultra High Definition Television) format – also known as SHV (Super Hi-Vision). UHDV, UHD is an experimental video format currently supported by NHK, BBC, and RAI. UHDTV provides at least 32 million picture elements with a maximum resolution of up to 7680×4320. For comparison, an HDTV frame in maximum quality consists of 2 million pixels (1920×1080). While the classic TV standard is equivalent to about 400 thousand pixels (720×576). The frame rate of UHDTV is 60 frames per second. An hour of uncompressed video in UHDTV format will take up about 25 terabytes. But with the help of compression algorithms, the size can be reduced to 300 gigabytes.
The minimum Ultra HD resolution is 3840 × 2160 pixels with a 16:9 aspect ratio.
4K Ultra HD is a new technology with incredible screen clarity and more vibrant colors than Full HD. Due to the fact that the number of pixels is much larger, and their size is much smaller, the picture is dense, and realistic, with clear outlines of each object.
Crystal UHD is the marketing name for LCD TVs, Crystal UHD TVs, and conventional matrix TVs made using standard technology without the use of quantum dot materials.
UHD (Ultra HD) is actually the same as 4K, but this format is more suitable for the average viewer and TV, and also has a lower resolution: 3840 × 2160 (2K). In short, UHD is a step up from Full HD.
