In unison with digital storage technologies, digital television (DVT) is quickly becoming a standard for television video. Three-dimensional-video (3D-video) is also a recent addition to video recording, where several cameras with real-time depth measurements are used to record three-dimensional videos. Several digital storage formats for video recording include DVD (digital versatile disc, sometimes called digital video disc), MPEG-4 (moving picture experts group-4), analog videotapes, VHS (video home system), and Betamax. Video technology, first developed for television, is being used in such forms as through the Internet, as streaming media clips on computers, and in DVDs, used in unison with televisions and computers. Video signals have much larger bandwidths (from 1 to 270 MHz or larger) than do audio signals ( ≥20 kHz), and thus involve a more complex recording and playback technology. The term video recording refers to storing a video signal (information designed to specify a moving image) in a recording medium such as magnetic tape, optical disc, or computer memory. ![]()
