DivX® occurs as video codec created by DivX, Inc. (formerly DivXNetworks, Inc.), regarded for its ability to compress lengthy video segments into small sizes while maintaining relatively high visual quality. DivX utilizes lossy MPEG-4 Part 2 compression, where quality is balanced against file size for utility. These are one of many codecs ordinarily associated by owning ripping, where audio and video multimedithe are transfered to a hard disk and transcoded. Following, DivX has been the center of tilt becaapply of its use in the replication & distribution of copyrighted DVDs.

Several freshly "DivX Certified" DVD players come take a breath to play DivX encoded picture, nonetheless, "DivX" is does'nt to become confused using "DIVX", an unrelated attempt at a fresh DVD rental system listed per US retailer Circuit City. Early versions of DivX involved just the codec, & were known as "DivX ;-)", in which a blinking emoticon was a tongue-within-facetious information to the failing DIVX rules.

History

DivX ;-) Three.Eleven Alphthe & earliest versions typically refer to a hacked version of the Microsoft MPEG-4 Version Two streaming video codec, extracted in 1998 by French hacker Jerome Rota (also referred to as Gej). A Microsoft codec, which originally needed that a compressed output exist as put around an ASF file, was altered to allow other containers such as AVI. From either 1998 across 2002, independent enthusiasts inside a DVD-ripping community created package information which dramatically enhanced a quality of videos files that a DivX ;-) Iii.Xi Alpha codec can garden truck. 1 notable thing is Nandub, a modification of the open-source VirtualDub, which features two-pass encryption (termed "Smart Bitrate Control" or SBC) when well as access to internal codec features.

Inside early 2000, Rotthe created a company (originally known as DivXNetworks, Inc., renamed to DivX, Inc. within 2005) to improve DivX & steward its development. the company freed a clean room version of the codec as DivX Four.Cypher within July 2001. DivX, Inc. has been granted patents in area of the DivX codec, which is fully MPEG-4-Advanced Simple Profile compliant. A next major version, DivX Five.Nought, was discharged around March 2002.

A latest generatiin, DivX 6, was freed on 15 June 2005 & expands a scope of DivX beyond "just a codec" to include the fully media container format. DivX 6 introduces a fresh media file format known as the "DivX Media Format" (by having the .divx extension) that includes trend lines for the as punishment DVD-such as features:

Interactive videos menus Multiple subtitles Multiple audio tracks Chapter points Other metadata

When around last generations, DivX was correspondent to cd formats like MPEG-Two, inside its Sixer.Nought generation, a freshly DivX Media Format is correspondent to media container formats. Lot in a way that media formats like DVD specify MPEG-Two streaming videos as a a portion of their specification, the DivX Media Format specifies MPEG-Four-compatible streaming videos as a a portion of its specification.

Current situation
A todays version of DivX (version Sestet.Zero.Iii) is available from either [http://www.divx.com/ DivX.com] for Windows 2000/XP. A latest version of DivX for Macintosh is version 5.Deuce.Ace, though a beta version of DivX 6 for Macintosh (minus a fully media format functionality) is available at the [http://labs.divx.com/ DivX Labs] site.

A todays version of DivX is neither free software nor open source, but an open source version of the codec—known as OpenDivX®—wwhen released by DivX inside early 2001, & this version served as a basis for the open source XviD codec, the specification of which is maintained by an independent class action. A format's independent competition in the for-license cd compression package market come Microsoft's Windows Media Streaming videos series, Apple Computer's QuickTime, and a RealNetworks RealVideo series.
