Ultra HD Blu-ray (UHD) is the future 4K Blu-ray Disc format. It will support 4K UHD (3840x2160 resolution) video at frame rates up to 60 frames per second. The standard will encode videos under the High Efficiency Video Coding standard(HEVC/H265). 4K Blu-ray Discs will support both a higher dynamic range by increasing the color depth to 10-bit per color and a greater color gamut by using the Rec. 2020 color space using HEVC. The 4K-Blu-ray specification allows for three disc sizes, each with their own data rate: 50 GB with 82 Mbit/s, 66 GB with 108 Mbit/s, and 100 GB with 128 Mbit/s. Wikipedia
Blu-ray Disc (abbreviation BD) is a next-generation optical disc format meant for storage of high-definition video and high-density data. The Blu-ray standard was jointly developed by a group of consumer electronics and PC companies called the Blu-ray Disc Association (BDA). As compared to the HD DVD format, its main competitor, Blu-ray has more information capacity per layer, 25 instead of 15 gigabytes, but may initially be more expensive to produce.
Wikipedia
AVCHD (Advanced Video Coding High Definition) is a file-based format for the digital recording and playback of high-definition video.
Developed jointly by Sony and Panasonic, the format was introduced in 2006 primarily for use in high definition consumer camcorders. Favorable comparisons of AVCHD against HDV and XDCAM EX[3][4] solidified perception of AVCHD as a format acceptable for professional usage. Panasonic released the first professional AVCHD camcorder in autumn of 2008, followed by Sony in the first quarter of 2010.
Wikipedia
HD DVD (High Density Digital Versatile Disc or High Definition Digital Video Disc) is a discontinued digital optical media format which is being developed as one standard for high-definition DVD. HD DVD is similar to the competing Blu-ray Disc, which also uses the same CD-size (120 mm diameter) optical data storage media and 405 nm wavelength blue laser. HD DVD is promoted by Toshiba, NEC, Sanyo, and, most recently, Microsoft, HP [1], and Intel. HD DVD was discontinued in February 2008.
