MPEG-4 Part 11 Scene description and application engine was published as ISO/IEC 14496-11 in 2005.{{cite web | url=http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=38560 | title=ISO/IEC 14496-11:2005 - Information technology -- Coding of audio-visual objects -- Part 11: Scene description and application engine | author=ISO | publisher=ISO | access-date=2009-10-30}} MPEG-4 Part 11 is also known as BIFS, XMT, MPEG-J.{{cite web |url=http://mpeg.chiariglione.org/technologies/mpeg-4/mp04-j/index.htm |title=MPEG-J White Paper |date=July 2005 |access-date=2010-04-11}}{{cite web |url=http://mpeg.chiariglione.org/technologies/mpeg-4/mpj-gfx/index.htm |title=MPEG-J GFX white paper |date=July 2005 |access-date=2010-04-11}} It defines:

• the coded representation of the spatio-temporal positioning of audio-visual objects as well as their behaviour in response to interaction (scene description);
• the coded representation of synthetic two-dimensional (2D) or three-dimensional (3D) objects that can be manifested audibly or visually;
• the Extensible MPEG-4 Textual (XMT) format - a textual representation of the multimedia content described in MPEG-4 using the Extensible Markup Language (XML);
• and a system level description of an application engine (format, delivery, lifecycle, and behaviour of downloadable Java byte code applications). (The MPEG-J Graphics Framework eXtensions (GFX) is defined in MPEG-4 Part 21 - ISO/IEC 14496-21.{{cite web | url=http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=41733 | title=ISO/IEC 14496-21:2006 - Information technology -- Coding of audio-visual objects -- Part 21: MPEG-J Graphics Framework eXtensions (GFX) | author=ISO | publisher=ISO | access-date=2009-10-30}})

Binary Format for Scenes (BIFS) is a binary format for two- or three-dimensional audiovisual content. It is based on VRML and part 11 of the MPEG-4 standard.

BIFS is MPEG-4 scene description protocol to compose MPEG-4 objects, describe interaction with MPEG-4 objects and to animate MPEG-4 objects.

MPEG-4 Binary Format for Scene (BIFS) is used in Digital Multimedia Broadcasting (DMB).{{cite web |url=http://mpeg.chiariglione.org/technologies/general/mp-drm/index.htm |title=MPEG Intellectual Property Management and Protection |date=April 2009 |publisher=chiariglione.org |access-date=2010-04-11}}

The XMT framework accommodates substantial portions of SMIL, W3C Scalable Vector Graphics (SVG) and X3D (the new name of VRML). Such a representation can be directly played back by a SMIL or VRML player, but can also be binarised to become a native MPEG-4 representation that can be played by an MPEG-4 player. Another bridge has been created with BiM (Binary MPEG format for XML).{{cite web | url=http://ride.chiariglione.org/bits_and_bytes/bits_and_bytes.htm | title=Riding the media bits - Bits and bytes | author=Leonardo Chiariglione | date=2005-03-08 | access-date=2009-10-30 | url-status=dead | archive-url=https://web.archive.org/web/20100925220237/http://ride.chiariglione.org/bits_and_bytes/bits_and_bytes.htm | archive-date=2010-09-25 }}
