  2. 2. Importance of Multimedia Delivery • Multimedia is predominant on the Internet • Real-time entertainment – Streaming video and audio – More than 70% of Internet traffic at peak periods • Popular services – YouTube (17.85%), Netflix (37.05%), Amazon Video (3.11%), Hulu (2.58%) – All delivered over-the-top (OTT) July 2016 ICME 2016 Grand Challenge, C.

OIPF HTTP Adaptive Streaming MPEG-DASH 3GPP Rel.10 DASH time V3… Reading: http://multimediacommunication.blogspot.com/2010/05/http-streaming-of-mpeg-media.html Today (2016): • 3GPP Rel. 13 (Mar’16) • DASH 2nd (May’14) • Many adoptions (e.g. DVB, HbbTV) • DASH 3rd (to be published 2016) • CMAF (to be published 2017)
  7. 7. The Goal of this Grand Challenge • MPEG-DASH defines formats only – Media Presentation Description (MPD) – Segment format: mp4, ts • MPEG-DASH is not – System, protocol, presentation, codec, interactivity, DRM, client specification – Other standards required for a complete ecosystem: e.g., DASH-IF, WAVE, HMTL5, MSE, EME • Aim of this grand challenge – Solicit contributions addressing end-to-end delivery aspects – Improve QoE while optimally utilising the available network infrastructures and its associated costs – Includes the content preparation for DASH, the content delivery within existing networks, and the client implementations July 2016 ICME 2016 Grand Challenge, C.
