MP3 is a standard audio format developed by Moving Picture Experts Group and uses MPEG-1 and MPEG-2 standardizations. MP3 uses lossy data compression, meaning that it loses quality over time. This sound format comes with a .mp3 filename extension and is today the most common audio format on websites and multimedia players.

MPEG-2 is a digital video coding format introduced in 1995 and later revised in 2013. It uses lossy video and audio data compressions and is very popular among video hardware, thanks to its low computational complexity. It is also widely used in cable and satellite broadcasting as well as writing DVDs.
