Analog video refers to a method of capturing and transmitting moving images using continuous signals. This technology relies on physical media, such as VHS tapes or analog broadcast signals, to store and convey video information. The quality of analog video can vary based on factors like tape condition and signal strength. In contrast to digital video, which uses discrete values to represent images, analog video captures the full spectrum of light and color. Common formats include NTSC, PAL, and SECAM, each with its own specifications for frame rates and resolution. Despite its decline in favor of digital formats, analog video remains significant in the history of visual media.
