The original video recording method that stores continuous waves of red, green and blue intensities.
In analog video, the number of rows is fixed. There are no real columns, and the maximum detail is determined by the frequency response of the analog system.
Analog video contains the luminance (brightness) and chrominance (color) of the image, which may be carried in separate channels, as in VGA, component video (YPbPr) and S-video, or combined in one channel, as in composite video and RF connector. Digital video signal formats with higher quality have been adopted and gradually replacing analog video, including serial digital interface (SDI), DVI and HDMI.
