Streaming-Multimedia Over 3G Networks
3rd September 2003
IMTC, the International Multimedia Telcommunications Consortium, has announced
the first interoperability tests over a live 3G network of real time multimedia
delivery through Packet Switched Streaming (PSS). Leading vendors in mobile
phone and network technologies have been conducting the first interoperability
tests at the Ericsson Research Center this week, thus making a decisive step
forward in enabling exciting new applications in mobile multimedia
communications.
The event has been organized by the IMTC PSS Activity Group (PSS-AG), and 12
PSS-AG member companies have been participating.
"So far our testing cycles have been mainly looking at the ability of our
different systems components to talk to each other. Now we have entered a
real-life environment, which means our activity has more value after we have
tested the behaviour of all the implementations over a cellular network,"
explains Amir Wolf, Chairman of the Activity Group. The tests were done over a
live WCDMA network provided by Ericsson, which allows the delivery of large
multimedia packets. "Together with the testing over the network, the group also
used a network simulator to test the behaviour of our multimedia servers and
clients in a noisy environment," says Ralph Neff, co-chairman of the Activity
Group.
The uses of this technology range from security to entertainment. For example,
the pictures from a camera overlooking an intersection in the morning-traffic
could be transmitted in real time over a wireless network onto a screen of a
mobile electronic device, giving users the possibility to select alternative
routes to avoid congestion. Breaking news could be watched without having to
store them first. Live entertainment could reach the mobile users.
The full set of 20,000 test results of this testing cycle were managed and
controlled by the web-tracking tool named "IOTZilla" supplied to the group by
Ximpo Group Ltd, Israel.
About PSS
The Packet Switched Streaming Activity Group was formed by the IMTC in order to
perform interoperability tests for Packet-Switched Streaming according to 3GPP
Technical Specifications 26.233 and 26.234, for delivering/streaming multimedia
content over wireless networks. It was established in fall 2000 with 3
participating companies. Since then the group has grown rapidly. Currently there
are 19 members, including the newest members Sony-Ericsson,
ST-Microelectronics, Qualcomm and Texas Instruments, which
joined in 2003. Other members of the Activity Group are: Emblaze Systems
(Israel), Emuzed (USA), Ericsson (Sweden), Fraunhofer IIS
(Germany), Hantro Products Oy (Finland), LGE (Korea),
LogicaCMG (USA), Mobixell Networks (Israel), Motorola
(USA), Nextreaming (Korea), Nokia (Finland), PacketVideo
(USA), RealNetworks (USA), Royal Philips Electronics (The
Netherlands) and Vidiator Technology (USA).
