The format is widely used on DVDs, Blu-rays, and digital television broadcasts. An AC3 stream can be stored as a standalone file or embedded in video containers such as MKV, AVI, or VOB.

MPEG is a compression standard for processing digital information. Designed for processing and transmission of both video and audio information. In total, there are five varieties, each of which is a refinement of the previous one and is intended for a narrower specification. Widely used by both ordinary users and TV companies. Does not lead to a noticeable deterioration in quality when compressed with the same bitrate. Compression occurs by replacing a sequence of frames with a colour space.
