* H. 264 also known as MPEG-4 Part 10, or as AVC, used for Blu-ray Discs and some broadcast television formats

It was further enhanced in projects known as H. 263v2 ( also known as H. 263 + or H. 263 1998 ), MPEG-4 Part 2 and H. 263v3 ( also known as H. 263 ++ or H. 263 2000 ).

MPEG-4 Part 2 is H. 263 compatible in the sense that a basic H. 263 bitstream is correctly decoded by an MPEG-4 Video decoder.

Such schemes have also been standardized for older designs as well, such as JPEG images with progressive encoding, and MPEG-2 and MPEG-4 Part 2 video, although those prior schemes had limited success in terms of adoption into real-world common usage.

* MPEG-4 Part 2 and Part 10 ( AVC )

It was formed in 2001 and its main result has been H. 264 / MPEG-4 AVC ( MPEG-4 Part 10 ).

It is also used on Blu-ray Discs, but these normally use MPEG-4 Part 10 or SMPTE VC-1 for high-definition content.

** MPEG-4 Part 2 ( or Simple and Advanced Simple Profile ) and

** MPEG-4 AVC ( or MPEG-4 Part 10 or H. 264 ).

Advanced Audio is also defined in Part 3 of the MPEG-4 standard.

AAC ( Advanced Audio Coding ) was standardized as an adjunct to MPEG-2 ( as Part 7 ) before MPEG-4 was issued.

* Parametric Stereo, Audio Object Type defined and used in MPEG-4 Part 3 ( MPEG-4 Audio ) to further enhance efficiency in low bandwidth stereo media

SVG capabilities are enhanced in MPEG-4 Part 20 with key features for mobile services, such as dynamic updates, binary encoding, state-of-art font representation.

SVG was also accommodated in MPEG-4 Part 11, in the Extensible MPEG-4 Textual ( XMT ) format-a textual representation of the MPEG-4 multimedia content using XML.

Windows Media Player 12 adds native support for H. 264 and MPEG-4 Part 2 video formats, AAC audio and 3GP, MP4 and MOV container formats.

For example, video created with a standard MPEG-4 Part 2 codec such as Xvid can be decoded ( played back ) using any other standard MPEG-4 Part 2 codec such as FFmpeg MPEG-4 or DivX Pro Codec, because they all use the same video format.

Whereas modern interframe video formats, such as MPEG1, MPEG2 and H. 264 / MPEG-4 AVC, achieve real-world compression-ratios of 1: 50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1: 20 or lower, depending on the tolerance to spatial artifacting in the compressed output.

* Simple Aggregation Format, a format for aggregating MPEG-4 Part 20 ( LASeR ) content with audio / video streams

* MPEG-4 Part 20, a rich media standard

* ASP ( one of about 20 profiles defined in MPEG-4 Part 2 )

* MPEG-4 Part 20 ( LASER )

It was developed by MPEG ( ISO / IEC JTC1 / SC29 / WG11 ) and defined in MPEG-4 Part 11 Scene description and application engine ( ISO / IEC 14496-11 ).

MPEG-4 Part 11 Scene description and application engine was published as ISO / IEC 14496-11 in 2005.

MPEG-4 Binary Format for Scene ( BIFS ) is used in Digital Multimedia Broadcasting ( DMB ).

* Symbolic Music Representation, used in MPEG-4 Part 3 and defined in MPEG-4 Part 23

* Advanced Simple Profile, an MPEG-4 video codec profile

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, by Nero Digital AVC, by QuickTime 7, and by high-definition video media like Blu-ray Disc ).

Xvid ( formerly " XviD ") is a video codec library following the MPEG-4 standard, specifically MPEG-4 Part 2 Advanced Simple Profile ( ASP ).

Since Xvid uses MPEG-4 Advanced Simple Profile ( ASP ) compression, any video that is encoded with it is termed " MPEG-4 ASP video " – not " Xvid video " – and can therefore be decoded with all MPEG-4 ASP compliant decoders.

This service used ISO MPEG-4 Version 1 Simple Profile @ L3 video and AAC audio encapsulated in MPEG transport stream.

HDCAM SR uses MPEG-4 Part 2 Simple Studio Profile for compression, and expands the number of audio channels up to 12 at 48 kHz / 24-bit.

As with the 440 and 880 mode, SR Lite utilizes the MPEG-4 Part 2 Simple Studio Profile but decreases the bitrate down to 220 Mbit / s for 60i and 183 Mbit / s for 50i.

The next enhanced codec developed by ITU-T VCEG ( in partnership with MPEG ) after H. 263 is the H. 264 standard, also known as AVC and MPEG-4 part 10.

MPEG-4 is a method of defining compression of audio and visual ( AV ) digital data.

MPEG-4 is still a developing standard and is divided into a number of parts.

MPEG-4 is efficient across a variety of bit-rates ranging from a few kilobits per second to tens of megabits per second.

Sony decided to choose Memory Stick Video format ( which actually is H. 264 / MPEG-4 AVC format ) as standard for Walkman MP3 Video Player.

Approaches exist to support modern video compression techniques ( such as MPEG-4 ) which rely on this function, although this is beyond the intent of the original specification and may cause problems with playback software which does not anticipate this use.

Even the original DVB standards can carry more HDTV channels in a multiplex if the most advanced MPEG-4 compressions hardware is used.

AAL's use of a " core " ( lossy ) and " residual " ( correction ) stream is similar to the idea behind MPEG-4 SLS, DTS-HD Master Audio, Dolby True HD and Ogg Vorbis bitrate peeling.

Twin vector quantization ( VQF ) is part of the MPEG-4 standard dealing with time domain weighted interleaved vector quantization.

* FFmpeg MPEG-4: Included in the open-source libavcodec codec library, which is used by default for decoding or encoding in many open-source video players, frameworks, editors and encoding tools such as MPlayer, VLC, ffdshow or GStreamer.

Theora is targeted at competing with MPEG-4 video and similar lower-bitrate video compression schemes.

3ivx ( ) is a video codec suite, created by 3ivx Technologies, based in Sydney, Australia, that allows the creation of MPEG-4 compliant data streams.

Only MPEG-4 Part 2 video is supported.

The system is DVB-T / MPEG-4 and in SFN configuration with 2 frequencies across the whole country ( north and south are UHF 26 while central is UHF 29 ).

Fifth and sixth generation iPod classics, as well as third generation iPod nanos, can additionally play MPEG-4 ( H. 264 / MPEG-4 AVC ) and QuickTime video formats, with restrictions on video dimensions, encoding techniques and data-rates .< ref > The restrictions vary from generation to generation ; for the earliest video iPods, video is required to be Baseline Profile ( BP ), up to Level 1. 3, meaning most significantly no B-frames ( BP ), a maximum bitrate of 768 kb / s ( BP Level 1. 3 ), and a maximum framerate of 30 frame / s at 320 × 240 resolution.
