Encyclopedia
MPEG-4 Part 11 Scene description and application engine was published as ISO/IEC 14496-11 in 2005. MPEG-4 Part 11 is also known as BIFS, XMT, MPEG-J. 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 and/or visually;
  • the Extensible MPEG-4 Textual (XMT) format
