MPEG-4 Part 11
Scene description and application engine
was published as
ISO
/IEC 14496-11 in 2005.
[1]
MPEG-4 Part 11 is also known as
BIFS, XMT, MPEG-J
.
[2]
[3]
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.

)
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).
[5]
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).
