Sharp Sharp is the only member of the HDV Consortium that has not produced an HDV camcorder or a videocassette recorder. The closest Sharp has ever got in supporting HDV standard is the AQUOS DV-ACV52 digital video player. The player supports HDV video, though it does not have a tape transport. Instead, it allows playback and dubbing of DV/HDV video from a camcorder connected to the player via a FireWire connector. Sony Sony specializes in 1080i HDV equipment and makes products for both 60 Hz and 50 Hz markets. Traditionally, Sony uses suffixes "E" and "P" to identify 50 Hz models, and suffix "U" or no suffix at all to identify 60 Hz models. Models listed below are specified without suffixes. In September 2004 Sony released the first HDV 1080i camcorder, the HDR-FX1. Its professional version, the HVR-Z1, came with XLR audio inputs and 44 additional features. Most notably, the HVR-Z1 was switchable between 50 Hz and 60 Hz scanning to cater for the different scanning rates used in different markets. In the middle of 2005 Sony released its first consumer HDV model, the HDR-HC1, which had a single CMOS sensor, electronic stabilization system and was capable of recording in DV and HDV 1080i modes. Its professional version, the HVR-A1, added a second accessory shoe in place of the flash, XLR audio inputs, additional recording options, larger eyecup and larger lens hood. In 2006 Sony replaced the HDR-HC1 with the smaller and cheaper HDR-HC3, which featured an incrementally improved CMOS chip, but omitted some features of its predecessor. The HDR-HC3 was replaced by the HDR-HC5 which used the same CMOS chip as the HDR-HC3, and added an option of recording in xvYCC color space. The replacement model, the HDR-HC7 came with a higher pixel count CMOS sensor and with a microphone input. Like the HDR-HC5, the HDR-HC7 could also record xvYCC. In 2008 the HDR-HC7 was replaced with the HDR-HC9. In 2006, Sony added two new models to its upscale HDV lineup: the "advanced amateur" HDR-FX7 and its professional cousin, the HVR-V1. The progressive-scan CMOS sensors of these models resolve full 1080 lines of vertical resolution. The HDR-FX7 records interlaced video only, while the HVR-V1 offers the choice of shooting interlaced or progressive video. Progressive video is converted to interlaced using pulldown for recording onto tape. In August 2007, Sony introduced the shoulder-mounted version of the HDR-HC7, the HVR-HD1000. In
