Seminar on MPEG-4
San Jose Convention Center
San Jose (CA), USA, 31st January 1998
During its 41st meeting in Fribourg, Switzerland, mpeg took a major step towards finalizing the first stage of the new mpeg-4
Multimedia Standard, by promoting the 'Audio', 'Video', 'Systems', 'DMIF' and 'Reference Software' parts of the Standard
to Committee Draft (CD). This means that the mpeg-4 standard under development has reached a very stable status, and
that 'National Standardization Bodies' will now be asked to comment and vote on it. The subsequent stages towards reaching
the status of International Standard in February '99 are Final CD (July '98) and Draft International Standard (December
'98).
The MPEG-4 standard as it is currently defined in the 'CDs' makes it possible to integrate natural and synthetic audio,
'classic' rectangular video and moving video 'objects' with an arbitrary shape, animated faces and animated 2D meshes with
several kinds of textures. Scalability is built into all the tools. The most bandwidth-hungry element, moving video, is currently
optimized for operation at bitrates from as low as 5 kbit/s to as high as 5 Mbit/s. Interlaced as well as progressive content are
supported. Audio covers the range from the extremely low bitrates (mainly for speech and synthetic audio) to transparent
quality, multichannel audio. An exceptional speech quality was demonstrated at a mere 2 kbit/s. The Systems layer allows
complex 'scenes' to be created, from the classical rectangular video with sound to virtual environments. The synchronised,
real-time play-out of the different objects is taken care of by the MPEG-4 Systems layer, which also supports user interaction
with the individual objects. A number of profiles have been defined for the Audio, Visual and Systems parts. These profiles
define tool subsets that cater for a large class of applications. MPEG is making available freely usable software, donated by
companies participating in MPEG, for all relevant parts of the standards (Audio, Visual, Systems, DMIF), to any party wishing
to use it for the development of MPEG-4 compliant products.
To promote the widest knowledge of this emerging multimedia standard, a Seminar on MPEG-4 will be held just before the
next MPEG meeting, in San Jose (CA), more precisely on Saturday, 31st January 1998. The Seminar will be held at the San
Jose Convention Center. At the Seminar, well known experts, very active in MPEG, will provide technology information and
updates on this basic multimedia technology.
The Seminar is for free (no registration fee) but you are kindly asked to send a message to Andy Tescher at
andy.tescher@lmco.com announcing your intention to participate.
