An ultra-high-definition video format being developed by NHK for next-generation TV broadcasting, with a resolution of 7,680×4,320 pixels, sixteen times higher than the current Full Hi-Vision video format.
A video encoding format characterized by more efficient compression than previous formats, such as MPEG-2. It is the current international standard for video compression, adopted by both the ITU-T (International Telecommunications Union Telecommunication Standardization Sector) and ISO/IEC (International Organization for Standardization/International Electrotechnical Commission). H.264 is said to achieve compression levels over two times better than those with MPEG-2, making it suitable for a wide range of applications, from low bit rate applications for mobile phones to high bit rate ones, such as high-definition TV.
