MPEG (Moving Picture Experts Group) is a family of digital video and audio compression formats that are widely used for storing and sharing video content. The formats are designed to provide high-quality video playback with relatively small file sizes, making them well-suited for distributing video content online. MPEG formats use a variety of video and audio codecs, including the H.264 video codec and the AAC audio codec, which provide high-quality video playback with relatively small file sizes. The formats also support a range of digital rights management (DRM) technologies, which allow content providers to restrict access to their content and prevent unauthorized copying. MPEG files can be played back on a variety of media players, including VLC, Windows Media Player, and QuickTime, and can also be converted to other more widely supported video formats like AVI or MP4 using compatible media conversion software. Overall, MPEG is a useful family of video file formats for storing and sharing high-quality video content, particularly for distributing video content online due to their widespread support and relatively small file sizes.
