What is the difference between .vob and .avchd?

Description: A VOB file is a movie data file from a DVD disc, typically stored in the VIDEO_TS folder at the root of the DVD. It contains a majority of the data stored on the disc which includes video, audio, subtitles, DVD menus and other navigation contents. VOB files are usually formatted as MPEG-2 system streams and can be opened by various video playback programs.; AVCHD (Advanced Video Coding High Definition) is a file format designed for recording and playing back high definition video. It is commonly used in digital camcorders and cameras for capturing HD footage. AVCHD leverages the MPEG-4 AVC/H.264 video compression codec, which efficiently reduces file sizes while preserving high-quality video resolution, and supports both Dolby AC-3 and linear PCM audio codecs for high-quality sound.
