Summary of TF

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

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

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

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

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

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

Dokodemo SOI Asia Anywhere, no limitations of network technologies Easy to use, no limitations of system compatibility

720p MPEG4 IPv6 Multicast over Satellite UDL

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

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

New Requirements Faster CPU: Core 2 Duo More application: VLC
