GeoVision Advanced MPEG4 Video Codec12/4/2023 Most of the features included in MPEG-4 are left to individual developers to decide whether or not to implement. The key parts to be aware of are MPEG-4 Part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid, Nero Digital and 3ivx and by QuickTime 6) and MPEG-4 part 10 (MPEG-4 AVC/ H.264 or Advanced Video Coding, used by the x264 encoder, Nero Digital AVC, QuickTime 7, and high-definition video media like Blu-ray Disc). Companies promoting MPEG-4 compatibility do not always clearly state which "part" level compatibility they are referring to. MPEG-4 is still an evolving standard and is divided into a number of parts. AAC (Advanced Audio Coding) was standardized as an adjunct to MPEG-2 (as Part 1) before MPEG-4 was issued. MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally specified Digital Rights Management and various types of interactivity. The MPEG-4 standard was developed by a group led by Touradj Ebrahimi (later the JPEG president) and Fernando Pereira. Uses of MPEG-4 include compression of audiovisual data for Internet video and CD distribution, voice ( telephone, videophone) and broadcast television applications. It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/ IEC Moving Picture Experts Group (MPEG) ( ISO/IEC JTC 1/SC29/WG11) under the formal standard ISO/IEC 14496 – Coding of audio-visual objects. MPEG-4 is a group of international standards for the compression of digital audio and visual data, multimedia systems, and file storage formats.
