[′vid·ē·ō]video
(1) Any digital moving picture, which includes a computer file in video formats such as MP4, MOV, M4V, AVI, DivX or FLV. A video may also refer to a DVD or Blu-ray disc. Years ago, a video was an analog tape recording (see video format). See MPEG, video codec and codec examples.(2) A computer display system. A "video card" is the same as a "graphics card" or "display adapter." A modern computer has one or more video interfaces such as DisplayPort, HDMI and VGA to send signals to the monitor. See DisplayPort, HDMI, VGA, display adapter and DVI.
(3) The moving picture technology developed for the television industry, initially for real-time capture and transmission and subsequently for recording and playback. In North America, the analog black and white TV standard (NTSC) that debuted in 1941 was replaced by digital TV (DTV) in 2009. In Europe and other countries, the analog PAL and SECAM color TV standards of the late 1960s were superseded by DVB and ISDB digital standards starting in the late 1990s. See NTSC, DTV, DVB, ISDB and VTR.
TV vs. Computer Color Encoding
TVs and computers use different color models. The color encoding of TV video signals (broadcast TV, cable TV, DVD, etc.) uses the YUV color space, whereas the computer's video system processes images in RGB. However, the screen electronics in both TVs and computers render only RGB, thus, YUV video is converted to RGB for display (see color space, YUV and RGB).
