Advanced Methodology For Interoperability Testing
Major Players In Mobile Media Industry Participate In Final Phase Of Six-Month Testing Program By IMTC PSS Activity Group
Paris, FRANCE -- (MARKET WIRE) -- Dec. 13, 2002 --
The Packet Switched Streaming Activity Group (PSSAG) of the International
Multimedia Telecommunications Consortium (IMTC) recently completed a series of
rigorous and comprehensive interoperability tests, at an interactive meeting in
which 12 mobile media industry leaders participated: Emblaze Systems (Israel),
Ericsson (Sweden), Fraunhofer IIS (Germany), Hantro Products Oy (Finland),
Mobixell Networks (Israel), Motorola (USA), Nextreaming (Korea), Nokia
(Finland), PacketVideo (USA), RealNetworks (USA), Royal Philips Electronics
(The Netherlands) and Vidiator Technology (USA). The meeting was hosted by the
MP4 Business Unit of Philips Electronics in Paris. Two more vendors which did
not take part in the meeting but participated during the cycle are CMG (USA)
and Siemens AG (Germany).
This meeting was the fifth in a series of phases to test and validate
end-to-end streaming between relevant components. Encoding and content
authoring were tested in addition to PSS servers and clients. The testing
points used were based on a range of different combinations of codecs and
profiles. More than 3500 results were documented during the live meeting and
over 10,000 testing points were successfully documented throughout the entire
six-month trial.
Improved and more thorough testing procedures and policies were used together
with a new fast and reliable test-tracking tool, developed specifically for
interoperability testing, to control the large number of testing points covered
during this six-month trial. Using this kind of advanced tracking tool, vendors
are able to concentrate on technical issues, investigating and tracking
thousands of results in a relatively short time frame.
The group established a liaison relationship between IMTC and 3GPP (3rd
Generation Partnership Program) and made significant contributions throughout,
particularly where the tests revealed areas where the 3GPP specifications could
be improved. Moreover, the group has published an 'Implementation Guide'
containing clarifications and interpretations to the Packet Switched Streaming
specifications, in order to encourage the development of interoperable
solutions.
"Our rigorous procedures and pioneering device, specifically developed for
interoperability testing, have helped raise the group's profile," says
Adi Plaut, Chairman of the PSS Activity Group. "The PSS AG currently has
sixteen members, and the numbers are expected to increase to 20 by early 2003.
The factors behind this expansion are twofold: Firstly, the mobile media
industry anticipates that Packet Switched Streaming will emerge as a
significant technology of the future, enabling exciting new applications in
mobile multimedia communications. Secondly, the PSS AG not only offers a
platform where different players in the market can analyse their R&D results in
a realistic environment, but also acts as a highly professional and advanced,
cost effective test tracking tool." A summary of the tested components of each
vendor and more information regarding the group and the tests can be found at
the IMTC PSSAG homepage (http://www.imtc.org/act_pss.htm).
About the PSS Activity Group
The PSS Activity Group was set up by IMTC in October 2001 to test the
implementation of Packet Switched Streaming techniques (according to 3GPP
Technical Specifications 26.233 and 26.234) for delivering/streaming multimedia
content over wireless networks. The group began its first test cycle at the end
of 2001 with three participants. There are now 16 members, representing the
major market leaders in mobile multimedia: CMG (USA), Emblaze
Systems (Israel), Emuzed (USA), Ericsson (Sweden),
Fraunhofer IIS (Germany), Hantro Products Oy (Finland),
LGE (Korea), Mobixell Networks (Israel), Motorola (USA),
Nextreaming (Korea), Nokia (Finland), PacketVideo (USA),
RealNetworks (USA), Royal Philips Electronics (The Netherlands),
Siemens AG (Germany) and Vidiator Technology (USA).
