  1. IMTC – PSS AGInteroperability tests PacketSwitchedStreaming Activity Group Third Testing Cycle Summary

  2. PSS AG Aim • Performing interoperability tests for Packet-Switched Streaming according to TS 26.233 and TS 26.234, for delivering/streaming multimedia content over wireless networks

  3. Status • The group just finished the Third testing cycle by performing a F2F meeting last week in Kista Sweden. • 15 vendors took part in the recent testing cycle. • The F2F meeting included testing over a WCDMA network as well as on a network simulator to simulate network errors • The F2F was the last phase of the cycle started at March 2003 by performing offline tests and streaming over the internet.

  4. Participants • Nokia • PacketVideo • Philips • Qualcom * • RealNetworks • Sharp * • Sony-Ericsson * • ST-MicroElectronics * • Texas Instriments * • Vidiator Technologies • Apple * • Emblaze Systems • Emuzed • Ericsson • Fraunhofer IIS-A • Hantro • LGE • LogicaCMG • Mobixell Networks • Motorola • Nextreaming *Joined for this cycle

  5. Sharp Apple Qualcomm Texas Instruments Emuzed LogicaCMG Sony-Ericsson ST Microelectronics Fraunhofer Ericsson Nokia Real LGE Nextreaming Hantro Vidiator Motorola Mobixell PacketVideo Siemens Emblaze Philips The Growth of PSS-AG

  6. New Vendors • 6 new vendors joined the group in the last 6 months: • Sony-Ericsson • ST-Microelectronics. • Qualcomm • Texas Instruments • Apple • Sharp

  7. Main Tested Components • Voice, audio and video CODECs • GSM/AMR (NB & WB) • AAC • H.263 • MPEG-4 Visual • Content negotiation & Transportprotocols • RTSP/SDP • RTP/RTCP • 3GPP/MPEG4 - File Format

  8. Test Procedure • The tests are being done according to a test procedure that is developed and constantly improved by the group members (currently at version 0.3) • It was tailored to meet the needs of the vendors and the reference specification • The test is composed of 5 stages that can be divided into 3 main groups: • Offline test • Raw bitstream • FF • Packetized bitstream (optional) • Virtual online test • Content negotiation / Transport protocols • Full system, Face-to-Face • Errorless / Simulated error condition

  9. Last Cycle Updates • Improved informative website • Improved testing document (ver 0.3) • Deployed automatic reporting tool (IOTzilla) • Implementation guide (ver 1.3) • Testing live streaming. • Testing SDP session establishment. • 2 technical liaisons were issued by the group and approved in SA#4. • Performing F2F over a 3G Cellular network. • About 20000 test points registered using IOTZilla.

  10. IOTzilla The PSS AG uses a unique tool named IOTZilla for tracking and managing the test points. The tool is provided to the group by Ximpo and gives us the following advantages:

  11. IOTZilla • Enables the group to grow while maintaining the efficiency of testing. • Saves history of problems identified during testing. • Easy and secured access. • Gives a correct status of the tests in real time. • Saves time for the engineers . • User friendly.

  12. IOTzilla

  13. Plans • Start the 4th testing cycle at October 2003 • Test new features • Create a procedure to allow more exposure of testing information to the outside world

  14. Participation Requirements • Developers of: • Streaming servers • Content creation tools • Multimedia terminals • Membership in the IMTC

  15. Steering & Outputs • Weekly ConfCall • Interoperability test procedures • Technical reflector • Test control Web-based tools (IOTzilla) • Implementation guide • Informative public reflector • PSS Interop PRs

  16. The PSS Group Qualities • Valuable discussion over a private reflector • High growth rate (6 new vendors during the last 6 months brings the group to 21 members) • Contributions to 3GPP according to practical tests • Cohesive group with common aims and goals oriented to PSS Interoperability • Strong, ever-improving cooperative spirit based on highly professional and personal attitude

  17. Why Join the PSS AG • The PSS AG is the only open group which tests PSS interop according to the 3GPP specificationsAll are welcome! • The PSS AG membership includes leading wireless multimedia vendors • The PSS AG is an active professional group that is growing fast to be the PSS interop leader

  18. Why Should You be There • Verify that your implementation is interoperable • Expand the proliferation of standards • Foster cooperation by creating direct channel at the engineerial level • Improve the PSS specification • Create market leverage
