A non-digital video signal used by most conventional video equipment for input or output. Video in which all the information representing images is in a continuous-scale electrical signal for both amplitude and time. Three basic analog video formats exist: NTSC, PAL, and SECAM. (See separate entries for more detailed information.)
The conventional NTSC television system in use today uses analog technology, in which the image sound and the picture brightness and color are represented by signals proportional to these values. The values of these signals are vulnerable to interference and noise. Digital television overcomes this vulnerability and delivers signals that are totally clean.
A video signal composed of a continuously varying electrical voltage.
A video format that captures and stores audio and video information as waves (rather than the binary one's and zero's of digital video). It refers to such magnetic tape formats as VHS, VHS-C, Super-VHS, and Hi-8. Analog video is subject to generational loss each time it is recorded and exported, and degradation due to noise, distortion, and other electronic phenomena over time.
Motion video from a VCR, older camcorder, laserdisc or Television, (RCA or S-VHS connection). At 640 x 480, 30 fps, analog format consumes 1 Gig of disk space per 30 minutes of video (VHS quality).
The ancestor to digital video, analog was once the medium of choice for wedding videographers. A VCR plays analog tapes, and subsequently, most home movies were shot on or transferred to analog tape. Even when stored properly, analog video will deteriorate over time.
A video signal that represents an infinite number of smooth gradations between given video levels.
The video output of most computers and videotape machines. Analog video can generate a large number of colors.
Any of the many formats that use an RF style (continuously varying voltage) wave form system to represent luminance and chroma information on magnetic Mylar tape. Analog formats include VHS, S-VHS, Betamax, Betacam, Umatic, 2†Quad & 1†Tape.
The variety of tape that is not digital. Generally, an older form of tape. Typically, home VHS tapes are analog
The variety of videotape that is not digital. Generally, an older form of videotape. Typically, home VHS tapes are analog.
Analog video is a video signal transferred by analog signal. It contains the luminance (brightness) and chrominance (color) of the image, which may be carried in separate channels, as in component video (YPb Pr) and S-Video, or combined in one channel, as in composite video and RF connector.
