Glossary:

MPEG-4 Part 14 or MP4 file format, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The official filename extension for MPEG-4 Part 14 files is .mp4, thus the container format is often referred to simply as MP4.Some devices advertised as "MP4 players" are simply MP3 players that also play AMV video or some other video format, and do not necessarily play the MPEG-4 part 14 format.

Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. AAC is also the default or standard audio format for: Apple's iPhone, iPod, iPad, Nintendo DSi, iTunes, DivX Plus Web Player, Sony's PlayStation 3 and is supported by Sony's PlayStation Portable, latest generation of Sony Walkman, phones from Sony Ericsson, the latest S40 and S60 models from Nokia, Android based phones, Nintendo's Wii (with the Photo Channel 1.1 update installed for Wii consoles purchased before late 2007), and the MPEG-4 video standard.
