ADVANTAGES CLOUD EN-/TRANSCODING
  How cloud-services can help?
  Faster time to market
  High scalability for increasing number of users
         Activation/Suspension of additional instances
         Compensation of fluctuating user numbers
          (e.g. evening vs. the rest of the day)
  Reduced costs for hardware infrastructure, support and
   maintenance
  Redundancy of systems and providers
  No/Low costs before market entry
  Cheap for testing new technologies such as adaptive
   Streaming
bitmovin / AAU Klagenfurt      Media Web Symposium 2013   18
E.g.: www.bitcodin.com
 Cloud-based Multimedia Encoding Service
 In closed test phase
 Input:
         Live Stream (e.g. RTP, HTTP, etc.)
         Upload/Batch, User Generated Content etc.
         Support for most popular formats/codecs
 Output:
         MPEG-DASH as well as Apple HLS Output
         Additionally the most popular formats/codecs
         Distribution to arbitrary servers/CDNs/platforms

bitmovin / AAU Klagenfurt    Media Web Symposium 2013        19
WHY CLOUD SERVICES?
 Comprehensive Interfaces (API) for the integration in
  existing encoding chains
 High reliability due to the usage of multiple cloud
  instances and multiple quality representations
         If one instance fails, the client automatically chooses
          another quality representation
 Different operation models:
         Private-Cloud on you own hardware
         Public Cloud-Infrastructure usage:

bitmovin / AAU Klagenfurt        Media Web Symposium 2013       20
CONCLUSIONS
 End-to-end DASH tools available
    GPAC (DASHEncoder) provide support for ISOBMFF, M2TS, etc.
    DASH VLC plugin and libdash (world first DASH player)
    DASH-JS for easy Web integration (HTML5, Javascript)
 Flexible architecture, easy to extend, e.g.:
    Add your own buffer model
    Add your own bandwidth estimation, adaptation logic
 Use cloud infrastructure to reduce costs/time to market
 Open source ressources:
      http://dash.itec.aau.at | http://gpac.sourceforge.net
