MPEG Video and Graphics News
MPEG has begun
work on a new part of the MPEG-C (ISO/IEC 23002-3) standard in Montreux. This new standard will support applications where
additional (auxiliary) data is needed that will be closely associated with
video content. This can be accomplished efficiently and it can be used by any
of MPEG's video coding standards. To begin, two types of auxiliary video data
will currently be specified targeting stereoscopic applications. Either a depth
map or parallax data can be coded using an MPEG video coding standard, and then
combined with another video stream to enable effective use of stereoscopic
displays. The specification can be easily extended beyond depth and parallax to
other data types. Support for the carriage of auxiliary data will be defined in
an amendment to MPEG-2 Systems.
The first MPEG-4
3D Graphics Player for mobile devices has been developed by INT - Institut National des Télécommunications
and IMEC -
A geographical map
navigation system using an optimized MPEG-4 player was demonstrated at the Montreux meeting. It shows that MPEG-4 can be used in an
application of view-dependent navigation having a large amount of geographical
data in 3D that includes both terrain and city data. The underlying tool is
part of an AFX (Animation Framework Extension) amendment to part 16 of MPEG-4
that will be complete in early 2007. The addition of such technologies to the
suite of MPEG-4 tools opens the field to a large variety of interoperable
applications where a common satellite/cadastral database can be augmented
on-the-fly and visualized on demand in different applications.
MPEG Audio News
At the Montreux
meeting MPEG continued its ongoing work on MPEG Surround and is now exploring
the potential for an amendment to the specification that will focus on two
topics. The first is the modeling of room effects using the MPEG Surround
framework to provide an efficient digital representation of the model of the
reflections in a real or virtual room. The second is the flexible coding of
audio sources or sound objects that will use the MPEG Surround framework to
realize bit rate efficient coding of multiple sound sources at arbitrary
positions in a sound stage or virtual environment.
The MPEG Symbolic Music
Representation standard has progressed to Committee Draft (CD) status and will
be finalized in July 2007. This new technology supports all the necessary
functionality to allow high quality coding of symbolic music to be integrated
with the existing MPEG-4 multimedia framework. Moreover, it will fill an
existing gap between the digital representation of music and its use by the
multimedia publishing industries. The new standard includes the definition of
two new XML schema and additional binary information. The first, symbolic Music
Extensible Format (SM-XL) enables the representation of music symbols composing
a music score (main score and individual parts), as well as lyrics. The second,
Symbolic Music Formatting Language (SM-FL) describes the insertion point and
positioning of music symbols and will specify a formatting rule-based language
and engine.
MPEG Systems News
MPEG Systems has achieved a
milestone in providing advanced tools for handling the complex multimedia
environment we now live in. Four parts of a planned 7-part standard called MPEG
Multimedia Middleware or M3W, as it is referred to, have achieved Committee
Draft (CD) status. While its title is “middleware”, M3W is much more. It
standardizes a system that includes Architecture, a Multimedia API, a Component
Model and a Resource and Quality Management each of which have been elevated to
CD in Montreux.
The remaining components or parts, Component Download, Fault Management
and System Integrity Management, will follow. Briefly, M3W is a multi-layer system
comprising of an Application, Middleware and Platform layer. The Application
layer is platform independent. The Middleware layer provides functionality to
the Application layer and makes use of the Platform layer. Along with the functional
parts there are “extra-functional” elements providing for instance resource,
fault, and integrity management as well as download and terminal management. MPEG
has provided a set of M3W white papers and a tutorial that describes M3W in
greater detail. These are available on the MPEG website (see below).
Additionally, MPEG
will provide support for JPEG2000 still images in an amendment to MPEG-4
Systems. MPEG-4 Systems is a feature rich standard that already supported
standard JPEG images. With the added support for JPEG2000 new applications
targeting content scalability are foreseen, including on-line game content and
geographical navigation.
Draft Call for Proposals on MPEG-7 Query
Format (MP7QF)
MPEG has issued a Draft Call for
Proposals on MPEG-7 Query Format (MP7QF). The final CfP
will be issued at the 77th MPEG meeting in
Digging Deeper
Communicating the
large and sometimes complex array of technology that the MPEG Committee has
developed is not a simple task. The experts past and present have contributed a
series of white-papers that explain each of these standards individually. The
repository is growing each meeting so if something you are interested is not
there yet it may be shortly - but do not hesitate to request it as well. You
