Next steps • Complete standardization work – Completion and publication of all specifications – Conformance, interoperability and reference software • Towards deployments – Generate end-to-end system specs based on <strong>DASH</strong> including codecs, DRM, profiles, etc. (OIPF, 3GPP, HbbTV, HD Forum, etc.) – Generate guidelines, white papers, test content and software – Promotional efforts: Licensing, interoperability, plug-fests, etc. – Combine it with browsers, the web and HTML-5 • Everyone is invited to contribute 50
Some Research Challenges • Client side implementation – Rate-adaptation for efficiency, high user experience, robustness – seamless switching experience – Usage and optimization of <strong>HTTP</strong>, TCP and lower layers – Efficient cloud-based trick modes • Content generation: – Switch points vs. efficiency (how frequent and how) – how many and which bit rates to offer – low-latency optimized content provisioning – caching optimized content generation • Media coding , e.g. efficient switch points • Cloud-support – caching (predictive caching, content management) • Transport and delivery (QoS, multicast, etc.) 51
