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

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
