MP, Mp, mp or .mp may refer to:
MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3 (or mp3), is an audio coding format for digital audio which uses a form of lossy data compression, which are data encoding methods that use inexact approximations and partial data discarding to reduce file sizes significantly, typically by a factor of 10, in comparison with a CD, yet still sound like the original uncompressed audio to most listeners.
MPEG-1 is a standard for lossy compression of video and audio. It is designed to compress VHS-quality raw digital video and CD audio down to 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) possible.
MPEG-4 is a method of defining compression of audio and visual (AV) digital data. It was introduced in late 1998 and designated a standard for a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC1/SC29/WG11) under the formal standard ISO/IEC 14496 – Coding of audio-visual objects.
MPEG transport stream (MPEG-TS, MTS or TS) is a standard digital container format for transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data.
The People's Movement for the Liberation of Angola, for some years called the People's Movement for the Liberation of Angola – Labour Party (Portuguese: Movimento Popular de Libertação de Angola – Partido do Trabalho), is a political party that has ruled Angola since the country's independence from Portugal in 1975. The MPLA fought against the Portuguese army in the Angolan War of Independence of 1961–74, and defeated the National Union for the Total Independence of Angola (UNITA) and the National Liberation Front of Angola (FNLA), two other anti-colonial movements, in the Angolan Civil War of 1975–2002.
MPEG-4 Part 3 or MPEG-4 Audio (formally ISO/IEC 14496-3) is the third part of the ISO/IEC MPEG-4 international standard developed by Moving Picture Experts Group.
