SD (Standard Definition)

Standard Definition (SD) refers to a video quality that has a resolution of 720×480 pixels (NTSC) or 720×576 pixels (PAL). It provides a clear picture, but less detail than higher formats like HD or 4K. SD was common for older TVs and DVDs, offering decent image quality suitable for everyday viewing. It requires less bandwidth and storage space compared to high-definition formats. While it’s now less prevalent, SD remains useful for basic television broadcasts, streaming, and devices with limited display capabilities.
