What is HDV?
The HDV format was developed by four companies: Canon Inc., Sharp Corporation, Sony Corporation, and Victor Company of Japan, Limited (JVC). These companies originally announced their HDV partnership in September, 2003. They have since been joined by other companies, notably Apple Computer.
JVC's GR-HD1 was the first camcorder based on HDV specs with 720p. In September 2004, Sony launched their first consumer HD camera, the Sony HDR-FX1, which can record the 1080i60 format (the PAL version records 1080i50) on a MiniDV tape using the HDV format. The professional version of this camera has both 50i and 60i capabilities, and adds XLR audio plus about 25 more features and is called the Sony HVR-Z1U. In 2005, Sony released the currently cheapest HDV Camcorder, the HDR-HC1. A professional version of the HC1 the Sony HVR-A1U was released Fall 2005. Canon introduced its first HDV camcorder, the Canon XL-H1, in September 2005. In late 2005, Panasonic took a different approach by introducing its Panasonic AG-HVX200 HDTV camcorder that records HD on the Panasonic's own DVCPRO-HD format. DVCPRO-HD reqires four times the bandwidth of HDV (100mbs vs 25mbs for HDV) but suffers less from compression and motion artifacts. The HVX200 records its HD signals on DVCPRO P2 cards only, with the Mini DV tape recorder for standard definition DV only. The camera also has an interface for directly recording DVCPRO-HD data on harddisk. (more)
