  2. Overview • Introduction • Related Works • Multimedia-aware Cloud • Cloud-aware Multimedia • Summary • Reference

  3. Overview • Introduction • Related Works • Multimedia-aware Cloud • Cloud-aware Multimedia • Summary • Reference

  4. Introduction • What is and why needs cloud computing? • Challenges of multimedia on cloud • Multimedia and service heterogeneity • QoS heterogeneity • Network heterogeneity • Device heterogeneity • Multimedia-aware cloud (media cloud) v.scloud-aware multimedia (cloud media)

  5. Multimedia on Cloud

  6. Media Cloud v.s Cloud Media

  7. Overview • Introduction • Related Works • Multimedia-aware Cloud • Cloud-aware Multimedia • Summary • Reference

  8. Overview • Introduction • Related Works • Multimedia-aware Cloud • Cloud-aware Multimedia • Summary • Reference

  9. Multimedia-aware Cloud • Media-cloud-computing architecture • Media edge cloud (MEC) architecture • Distributed parallel multimedia processing • Case study • Photosynth[1]

  10. MEC Architecture • Like CDN[2]edge servers architecture

  11. MEC Architecture

  12. Distributed parallel multimedia processing DHT Load Balancer

  13. Case Study - Photosynth

  14. Case Study - Photosynth • Major computation task • Image Conversion • Feature extration • Image matching • Reconstruction • User-level parallel synthing in the MEC • Task-level parallel synthing in the MEC

  15. User-level Parallel Synthing

  16. Task-level Parallel Synthing

  17. Simulation Result

  18. Overview • Introduction • Related Works • Multimedia-aware Cloud • Cloud-aware Multimedia • Summary • Reference

  19. Cloud-aware Multimedia

  20. Cloud-aware Multimedia • Storage and sharing • Authoring and mashup • Adaptation and delivery • Media rendering

  21. Storage and sharing • Advantage • High reliability • High data rate • Issues • High bandwidth demand of load balancing algorithms for streaming

  22. Authoring and Mashup • Offline tools • Adobe • Windows Movie Maker • Online service • Jaycut • http://www.jaycut.com • XML-based file format

  23. Authoring and Mashup

  24. Adaptation and Delivery • A large amount of computing • Request service simultaneously • Example – Cloudcoder • Offload much of the processing to the cloud • Transcoder instances scales up automatically

  25. Adaptation and Delivery

  26. Media Rendering • A large amount of computing • Fully render • Partially render • Multimedia retrieval • Content-based image retrieval (CBIR) • Feature extraction • Similarity measurement

  27. Media Rendering

  28. Overview • Introduction • Related Works • Multimedia-aware Cloud • Cloud-aware Multimedia • Summary • Reference

  29. Summary • Media cloud • Propose an MEC-computing architecture to achieve high QoS support for various services. • Cloud media • Propose how multimedia service can optimally utilize cloud-computing resources.

  30. Overview • Introduction • Related Works • Multimedia-aware Cloud • Cloud-aware Multimedia • Summary • Reference
