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 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.
In 2011 the AVCHD specification was amended to include 1080-line 50-frame/s and 60-frame/s modes (AVCHD Progressive) and stereoscopic video (AVCHD 3D). The new modes also allow higher system data rate than existing modes.
AVCHD and its logo are trademarks of Panasonic and Sony.For video compression, AVCHD uses the MPEG-4 AVC/H.264 standard, supporting a variety of standard, high definition, and stereoscopic (3D) video resolutions. For audio compression, supports both Dolby AC-3 (Dolby Digital) and uncompressed linear PCM audio. Stereo and multichannel surround (5.1) are both supported.
Aside from recorded audio and video, AVCHD includes features to improve media presentation: menu navigation, slide shows and subtitles. The menu navigation system is similar to DVD-video, allowing access to individual videos from a common intro screen. Slide shows are prepared from a sequence of AVC still frames, and can be accompanied by a background audio track. Subtitles are used in some camcorders to timestamp the recordings.
