McLaren MP4-21

The McLaren MP4-21 is a Formula One car designed by Adrian Newey for the 2006 Formula One season. The car continues the MP4-X naming system and is notable for its striking chrome livery designed to maximize the visibility of the team's new primary sponsor Emirates. The distinctive needle-nose design was previously used on the MP4-19 in 2004.

The car started the season in the hands of Kimi Räikkönen and Juan Pablo Montoya, but after a few races it soon became clear that it was not as competitive as its predecessor, the MP4-20, despite an apparent improvement in reliability. McLaren did not win a race all season, for the first time since 1996. Their best results were second-place finishes for Kimi Räikkönen in Australia and Italy, for Juan Pablo Montoya in Monaco, and for Pedro de la Rosa in Hungary.

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.

MP4 (band)

MP4 is a rock band made up of four British Members of Parliament.

Members

It was founded as MP3 in 2004 by Pete Wishart (Scottish National Party, Perth and North Perthshire) on keyboards, Ian Cawsey (The former Labour MP, Brigg and Goole) on bass guitar and vocals, and Greg Knight (Conservative, East Yorkshire) on drums. They were later joined by Kevin Brennan (Labour, Cardiff West) on guitar, and changed their name to reflect this. Wishart was previously keyboardist with Runrig and Big Country. Along with David Morris (Conservative, Morecambe and Lunedale) Wishart is one of only two current MPs to have appeared on Top of the Pops.

The band first came to media attention in 2003, when the project was described as being in its "early stages".

Three of the four members were re-elected at the 2010 General Election but bassist Ian Cawsey lost his seat. He remains a band member however, and the group has indicated they intend to continue with the same line-up.

Recordings

In 2005, MP4 recorded an EP entitled House Music, which was initially released as a download by EMI, and later in CD format by Busy Bee Records. The EP features cover versions of the Beatles' Can't Buy Me Love, Wilson Pickett's In the Midnight Hour and Steve Earle's My Old Friend the Blues, along with the Brennan-penned original Foolish Game.
