Chapter 14 - HD Video Cameras
HDV Format
HDV was announced in the summer of 2003 and was
established as an official format in the fall of 2003.
Canon, JVC, Sharp, and Sony are the primary
manufacturers supporting this HD format that uses mini-
DV videotape, MPEG-2 and at resolutions of 1080i and
720p. The companies indicated that camcorders could be
made that can record on the same mini-DV both regular
and HD formats.
AVCHD Format
Panasonic co-developed this standard with Sony. The format is capable of recording
1080i or 720p video to standard DVDs. In July 2006, both companies announced
that the format was to be expanded to record in flash memory cards and hard disc
drives.
AVCHD based camcorders were first launched by Sony. Hitachi will launch their
AVCHD model in 2007.
Panasonic was quoted as declaring “Our development teams are studying the
feasibility of a Blu-ray disc camcorder, since the AVCHD format is compatible with
Blu-ray, the former would not be made obsolete with the advent of Blu-ray disc
camcorders”.
AVCHD records onto standard 3-inch DVD discs, which can be played back on
Panasonic and Sony Blu-ray disc players, and Sony’s Playstation 3.
Canon, Sharp, Cyberlink, Intervideo, Nero AG, Sonic Solutions, Ulead Systems,
Samsung, and Pioneer support the AVCHD format.
