A video format describes how one device sends
video pictures to another device, such as the way that a DVD player sends pictures to a television, or a computer to a monitor. More formally, the video format describes the sequence and structure of
frames that create the moving video image.Video formats are commonly known in the domain of commercial broadcast and consumer devices; most notably to date, these are the analog video formats of
NTSC,
PAL, and
SECAM. However, video formats also describe the
digital equivalents of the commercial formats, the aging custom military uses of analog video (such as RS-170 and RS-343), the increasingly important video formats used with
computers, and even such offbeat formats such as color field sequential.
