AVCHD (Advanced Video Coding High Definition) is a format for the recording and playback of high definition video.
Developed jointly by Sony and Panasonic, the format was announced in 2006 primarily for use in high definition consumer camcorders. Recording media includes DVD discs, hard disk drives, non-removable solid-state memory and removable flash memory such as Secure Digital and Memory Stick cards.
Sony and Panasonic released the first AVCHD camcorders in autumn of 2006, followed by Canon and JVC. Favorable comparisons of AVCHD against HDV and XDCAM EX solidified perception of AVCHD as a format acceptable for professional usage. As the standard matured, Panasonic released the first professional AVCHD camcorder in autumn of 2008, followed by Sony in the first quarter of 2010.
AVCHD has been designed to be compatible with Blu-ray Disc format and can be used for authoring and distributing of high definition video on DVD media, though not all Blu-ray Disc players are compatible with AVCHD discs.
