Canon introduced the consumer-oriented Canon HV10, a compact unit with a single 2.76 megapixel CMOS sensor. The camera recorded interlaced video only. In April 2007 Canon released the HV20 which used the same sensor and internal processor as the HV10, had a larger lens and more conventional layout. This was the first consumer HDV camcorder that featured progressive shooting modes in addition to native interlaced recording. Progressive-scan video was recorded within interlaced container to remain compatible with consumer level editing suites. The version for 50 Hz market offered PF25 mode, which utilized Progressive segmented Frame technique, while the 60 Hz variant featured PF24 mode, which utilized 2-3 pulldown scheme. The HV30, released in 2008, was a minor update of the HV20. The body color has been changed from silver to black, the LCD screen has been improved, and the 60 Hz variant implemented PsF-like PF30 mode. In 2009 Canon released the HV40. Its 50 Hz variant was practically identical to the HV30, while the 60 Hz variant became the first consumer HDV camcorder capable of native progressive 24 frames/s recording. JVC In 2003 JVC released the first HDV camcorder — the handheld GR-HD1. The camcorder offered standard DV recording mode, HDV 720p30 and HDV 480p60. The HDV modes used the older Rec. 601 standard for color space, rather than the newer Rec. 709 standard intended for high-definition video. The imager of the GR-HD1 used a single 1/3" CCD sensor instead of a 3CCD setup, another unusual choice discouraging professional use. The GR-HD1 was not popular in either the consumer or semi-professional market, and JVC later shifted its HDV development to professional shoulder-mounted cameras. The shoulder mount GY-HD100 camcorder was released in 2005 and featured 3CCD imaging system with native 720p resolution, interchangeable lens and 24 frame/s recording. Because of the latter feature this camcorder became popular for shooting "digital movies". The updated version, GY-HD110, provides several updates and fixed split-screen effect found on some GY-HD100 cameras. The GY-HD200, released later, offered 50p/60p recording, 720p-to-1080i converter and Anton Bauer professional battery with mount. In 2006 JVC released the GY-HD250, which simplified multi-camera recording by providing genlock and time code input/output. HD/SD-SDI output allowed to record uncompressed video. In 2008 the "B" modification of the GY-HD200 was released, allowing live recording of either 720p or 1080i signal onto an external tapeless recorder. Recording to tape was still performed in 720p mode only.
