  1. Summary of TF

  2. Topics • New UDLR receiver box and ULE • Activities and Connectivities with other RENs • Dokodemo SOI Asia • Satellite resource allocation • Jaxa event

  3. New UDLR box & ULE • Current situation • AI3/SOI Asia UDL uses a modified MPE format , not efficient bandwidth utilization • Difficulty on operating UDcast Box • More R&D cannot be implimented • UDbox -> New UDLR box development • Might improve current problems of operation and maintenance, logistic difficulty and downtime • More possibilities of R&D • Cheaper? • More flexible logistics, install and troubleshoot • Development status • Benchmark performance test is OK but need stability and durable test • Documentations, CLI/GUI user interface

  4. New UDLR box & ULE • MPE -> ULE • Improving bandwidth utilization • More standard, more R&D • Issues • Test • Separate research bandwidth for ULE box test • Called for test partners, starting around end-feb to march • tu, unsrat, itc, unsyiah , buet • Logistics • Some distribution hubs or from USM or self-install • Budget • Next actions • Discuss more details in UDL WG • Propose the plan to Directors meeting

  5. Resource allocation • Satellite bandwidth is limited and more Tx partners • Proposal to reorganize Tx partners into 2 categories • Research category for temporary period • Lifeline category (24/7) • Issues • Policy and procedure must be defined and executed efficiently • If there is no TX regularly, can still maintain license? Need to check – per country • Need to discuss more in director meeting and with each partner team

  6. Activities and Connectivities with other RENs • How can we AI3/SOI Asia group work and contribute to other RENs? Tein3, APAN

  7. Activities and Connectivities with other RENs • NREN formation support from experiences in AI3/SOI Asia group members • Technology, content, depends on requests • Tein3 or APAN collaboration • From strong partnership and content from SOI Asia • Thinking about appointing one partner to be our representative and show our status • No formal agreement is expected now

  8. Dokodemo SOI Asia • Anywhere , no limitations of network technologies • Easyto use, no limitations of system compatibility

  15. 720p MPEG4 IPv6 Multicastover Satellite UDL

  16. 720p MPEG Streaming 1080i HD-SDI Edirol 300HD HDV 720p IEEE1394 Core 2 Duo 2.2GHz Ubuntu 8.04 VLC, dvgrab, webserver SFC 4.5Mbps MPEG4 IPv6 Multicast Real-time interpreters: EN, TH, ID RAT IPv6 Multicast

  17. Problems, Lessons, Todos • Encoding • MPEG2/720p – Raw Video – MPEG4/720p 4Mbps (no audio transcoding) • 40-60% CPU on Core 2 Duo 2.2GHz • 3-5 sec latency (dvgrab? VLC transcoding?): quality vs interactivity • Hurry FFMPEG encoding: block noise • Is 4Mbps the best? Quality vs bandwidth use • RSS running text • Web server on encoder machine • Audio level is low • Decoding • VLC and RAT machine must be different to prevent VLC audio feedback via RAT

  18. New Requirements • Faster CPU: Core 2 Duo • More application: VLC
