It is a file-based format available for both digital recording and playback of a high-definition video. AVCHD is an acronym that stands for Advanced Video Coding High Definition. The AVCHD format was first used in 2006 after Sony and Panasonic joined to make it. It is mostly used in high definition consumer camcorders. As a format, AVCHD is much like HDV and is a format that professionals use. Not all Blu-Ray Disc players support playback of the AVCHD format. This is because it is not part of the Blu-ray Disc specification, even though AVCHD has a format much like the Blu-ray Disc.
