MPEG-4 Part 14

MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio, but can also be used to store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. The only official filename extension for MPEG-4 Part 14 files is .mp4, but many have other extensions, most commonly .m4a and .m4p. M4A (audio only) is often compressed using AAC encoding (lossy), but can also be in Apple Lossless format. M4P is a protected format which employs DRM technology to restrict copying. MPEG-4 Part 14 (formally ISO/IEC 14496-14:2003) is a standard specified as a part of MPEG-4.

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.

History of MP4

MPEG-4 Part 14 is an instance of the more general ISO/IEC 14496-12:2004 (MPEG-4 Part 12: ISO base media file format) which is directly based upon the QuickTime File Format. MPEG-4 Part 14 is essentially identical to the QuickTime file format, but formally specifies support for Initial Object Descriptors (IOD) and other MPEG features. MPEG-4 Part 14 revises and completely replaces Clause 13 of ISO/IEC 14496-1 (MPEG-4 Part 1: Systems), in which the file format for MPEG-4 content was previously specified.

History

Formation and early years: 1975–1980

Chrissie Hammond, Russell Hitchcock, and Graham Russell met in May 1975 while performing in the Australian production of the Andrew Lloyd Webber and Tim Rice musical, Jesus Christ Superstar. With Hammond and Hitchcock on vocals and Russell on guitar, they formed a harmony vocal group in Melbourne, while the show was still playing. Hammond left the vocal group to form Cheetah and was replaced by Jeremy Paul (ex-Soffrok and later Divinyls) on bass guitar and vocals in 1976. Together, Hitchcock, Russell and Paul formed Air Supply. The group's first single, "Love and Other Bruises", was released in November, 1976 and peaked at No. 6 on the Australian Kent Music Report Singles Chart in January 1977. It was followed by Air Supply, their debut album, in December, which reached No. 17 on the Kent Music Report Albums Chart and achieved gold in Australia. The album was produced by Peter Dawkins (Spectrum, Ross Ryan) with Air Supply line-up as Hitchcock, Paul, Russell and drummer Jeff Browne, guitarist Mark McEntee and keyboardist, arranger Adrian Scott. Other singles were "If You Knew Me", "Empty Pages" and "Feel the Breeze" but none reached the Top 40. A national tour followed with Hitchcock, Paul, Russell and Scott joined by Nigel Macara (ex-Tamam Shud, Ariel) on drums and Brenton White (Skintight)on guitar. Brenton White rehearsed but did not perform with Air Supply
