5. Conclusion


Trend and requirement in multimedia services

(1) Consumers participation in multimedia contents creation - Former “Consumer” and “User” roles are beginning to provide contents a

nd values in the multimedia services. - “Peer-to-peer” contents sharing demands an environment for the re-use (fa

brication) of contents. - Community-oriented contents sharing is key for the market expansion.

(2) Participation of market with low initial cost - Contents provider/ creator prefer environment for low-barrier and quick p

articipation in the market.

(3) Mediator for rights and commission is needed - Peer-to-peer contents sharing requires a mediating role to resolve rights an

d payment problems.

XML description ofapplication service QoS

Multimedia stream

“Frame rate should be at least 30 [fps]”

“Scene change gapshould be within XX [sec]”

Synchronization gapshould be within XX[sec]”

-Application service QoS is described using XML tags, indicating visual presentation quality, demanded by the content creators.


Application service QoS

Network Service QoS (e.g. for ATM)

Control information forapp. level communication

- Data transmission rate- Stream buffer size- Data transmission schedule- Priority control

- Service class (CBR, VBR,…)- Cell rate （ Peak / Sustainable)- Maximum burst size (MBS),- Peak-to-Peak cell delay variation- Maximum cell transmission delay- Cell loss rate(CLR)- Traffic policing ／ Shaping parameter

QoS info mapping

Repository

Mapping of QoS information

- Image size- Image precision, color palette information- Compression rate- Frames per second- Delay ／ synchronization gap tolerance- Frame loss rate tolerance
