analog video

Analog video is a method of transmitting visual information as continuous electronic signals, capturing light and color variations from a scene. These signals are stored and transmitted as changing electrical wave patterns, which represent the brightness (luminance) and color (chrominance) of the image. When displayed on a monitor or TV, the analog signals are converted back into visual images. Unlike digital video, which uses binary data, analog video is continuous and can be more susceptible to noise and degradation over time or distance. This technology was commonly used in traditional TVs and videotapes before digital formats became standard.
