An MPEG-2 video encoding mode in which half the horizontal resolution is sampled (352x480 for NTSC, 352x576 for PAL). See also D1




HD-DVD, HDDVD, HD DVD
HD DVD (High Density DVD or High Definition DVD) is a next-generation optical disc format designed for high-density storage of high-definition video and data.

HDCP
High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed by Intel Corporation to prevent copying of digital audio and video content as it travels across DVI or HDMI, even if such copying would be permitted by fair use laws.

HDMI
HDMI (High-Definition Multimedia Interface) is the first industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an interface between any audio/video source, such as a set-top box, DVD player, and A/V receiver and an audio and/or video monitor, such as a digital television (DTV).
HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel digital audio, with bandwidth to spare to accommodate future enhancements and requirements.

HDTV
High Definition TV is high-resolution digital television combined with Dolby Digital surround sound (AC-3). HDTV is the highest DTV resolution in the new set of standards. This combination creates a stunning image with stunning sound. HDTV requires new production and transmission equipment at the HDTV stations, as well as new television equipment for reception by the consumer. The higher resolution picture is the main selling point for HDTV. Imagine 720 or 1080 lines of resolution compared to the 525 lines people are used to in the United States (or the 625 lines in Europe) -- it's a huge difference!
Of the 18 DTV formats, six are HDTV formats, five of which are based on progressive scanning and one on interlaced scanning. Of the remaining formats, eight are SDTV (four wide-screen formats with 16:9 aspect ratios, and four conventional formats with 4:3 aspect ratios), and the remaining four are video graphics array (VGA) formats. Stations are free to choose which formats to broadcast.
The formats used in HDTV are:
720p - 1280x720 pixels progressive
1080i - 1920x1080 pixels interlaced
1080p - 1920x1080 pixels progressive




HDV
High Definition Video (HDV) is a video format designed to record compressed HDTV video on standard DV media (DV or MiniDV cassette tape).
http://en.wikipedia.org/wiki/HDV




Hi8
Analog camcorder format which allows you to record video with 400 lines of resolution onto Hi8 tape, or 240 lines of resolution onto standard 8mm tape. Hi8 tapes can get up to 2hours in SP and 4hours in LP modes. Most Hi8 tapes will work in Digital8 camcorders but typically only can record 1 hour of Digital video.




HQ-VCD
High-quality Video Compact Disc. Developed by the Video CD Consortium (Philips, Sony, Matsushita and JVC) as a successor to VCD. Evolved into SVCD.




HTPC
Home Theater Personal Computer, a computer designed to be used as a media center for digital home entertainment such as Movies, Music, Television, Games. http://www.htpcnews.com/




Huffyuv
A fast, lossless Win32 video codec developed by Ben Rudiak-Gould. "Lossless" means that the output from the decompressor is bit-for-bit identical with the original input to the compressor. "Fast" means a compression throughput of up to 38 megabytes per second on a 416 MHz Celeron. Huffyuv is intended to replace uncompressed YUV as a video capture format. It is fast enough to compress full-resolution CCIR 601 video (720 x 480 x 30fps) in real time as it is captured. Huffyuv also supports lossless compression of RGB data, so it can be used for the output of programs like VirtualDub. Creator's Site




HVD
HVD is an Asian standard of advanced high-definition technology originally developed in China by AMLogic Inc., for high-definition video. The format resolutions support 720p, 1080i, or 1080p on version 1 discs. Version 2 of the format added high-resolution beyond the standard fare of HD for use on non-TV monitors that support higher resolutions, up to 1880p.
