Standard Definition (SD)

Standard Definition (SD) refers to a video quality format that displays images at a resolution typically of 480p or 576i, which is lower than High Definition (HD). SD provides a clear picture suitable for many television broadcasts and streaming services, but it has less detail and sharpness compared to HD or Ultra HD formats. It requires less data, making it easier to stream or transmit with limited bandwidth. SD is often associated with older TV sets and broadcasts, serving as a baseline video quality standard before higher resolutions became widely available.
