A*STAR's Exploit Technologies And Institute For Infocomm Research Launch World's First Adaptive Audio Streaming Technology Using The MPEG-4 SLS Audio Standard
1/6/2010 2:04:48 PM
Singapore, 6 January 2010 – Exploit Technologies, the commercialisation arm of Singapore
Agency for Science, Technology and Research (A*STAR), and the Institute for Infocomm
Research (I2R) today announced MPEG4-SLS (Scalable-to-Lossless Coding), the world’s first
adaptive audio streaming technology using the MPEG-4 SLS audio standard. This technology will
be presented by Exploit Technologies during the 2010 International Consumer Electronics Show
(CES) at booth North 4638 and North 6817.
SLS is a music coding format developed with major contribution from A*STAR Institute for
Infocomm Research (I2R) and Fraunhofer-Gesellschaft (FhG). This patented music coding format
is an MPEG-4 audio standard that is capable of compressing music files (such as CD tracks) for
playback without any loss in fidelity. It also allows for fine-grain pre-encoding of music files at
different bit-rates so that they can be subsequently streamed or played back at different
quality, depending on the device type or available channel bandwidth. This allows for
uninterrupted music streaming all day round, regardless of bandwidth or internet traffic
volume. MPEG-4 SLS’s scalability also means that a single encoded file can be played back on
different environment with bit-rate cap determined by the service provider.
“Exploit Technologies leverages different commercialisation platforms to bring to the market
A*STAR’s technologies. When MPEG-SLS was launched a few years ago, there was little interest
in the use of this technology. By focusing development on adapting MPEG-4 SLS for streaming
audio, a solution is now available to support streaming music services and at the same time
pave the way for the future with HD audio. We believe that this innovative adaptive technology
could completely change the digital music industry, just as the introduction of MP3 did many
years ago,” said Philip Lim, Chief Executive Officer of Exploit Technologies.
MPEG-4 SLS: Unleashing the power of the digital recorded music industry
Adaptive MPEG-4 SLS offers seamless audio streaming that opens a new realm of music
entertainment possibilities. Thanks to the technology, high-music entertainment is no longer
limited to desk-bound hi-fi systems. MPEG-4 SLS is an attractive format for streaming
applications due to its scalability feature. This feature enables a streaming system to respond to
network conditions in real time during a streaming session.
The A*STAR I²R team was awarded the National Technology Award 2007 for its research and
development work on SLS. Said Prof Lye Kin Mun, Deputy Executive Director (Research) of I2R,
“Our research team developed this technology to answer the needs of new generation
consumers who want hi-fidelity music entertainment at the appropriate quality and on
demand, anywhere anytime. This is also in line with upcoming trends of moving away from
traditional to new media in the infotainment world”
The digital distribution of music stands fully ready to become the dominant way in which music
will be produced and consumed. Now that the consumers have access to millions of
soundtracks, the challenge would be to find the music that one really wants to hear, quicker
and more accurately. Adaptive MPEG-4 SLS may provide the missing piece to the puzzle for
service providers of digital music content.
MPEG-4 SLS is currently being test-bedded online at www.songsofcampus.com. Exploit
Technologies welcomes industry partners to join our efforts to commercialise MPEG-4 SLS.
