Introduction – Key Players*
Standards – Hybrid TV + Web Standards
§ As content providers are diversifying their target audience…
– common authoring basis to address those different devices
(Internet,TV, tablets, mobiles)
– faster authoring time for simple applications or reuse of existing
solutions (e.g. reuse of backend and only frontend adaptations)
– benefit from the WWW community and capitalize on existing
content of the Web.
– Browser as common denominator
App platforms
§ TV app platforms are different
– Samsung has 1000 apps available and ten
million downloads
– LG, Sharp and Philips to define common
platform (HTML/HbbTV-based)
– Google TV based on Android and partnering
with Sony
⇒ Expensive for content providers to
deploy one service to all TV platforms
⇒ BUT, common basis is (CE-) HTML
+JavaScript
Standards – Hybrid TV / HbbTV

– Broadcast-independent application
§ not associated with any broadcast service
§ downloaded via broadband and accesses all of its associated data via
broadband
– Broadcast-related application
§ associated with one or more broadcast services or one or more broadcast
events within a service
§ may be launched automatically ("autostart") or explicitly upon user request.
§ may be downloaded broadband or broadcast and may access its data via
either

§ Two primary components
– A media format delivered over HTTP as file “segments”
– A presentation description file (“manifest”) to provide information to a
player about the media available
§ Uses HTTP and existing content delivery infrastructure
– Video passes through firewalls, NATs etc. same as web pages
§ Client selects from video files encoded at different bitrates
– Adapts to changing network conditions and throughput
– Maintains continuous playback at the highest quality the network can
currently support
§ Dynamic Adaptive Streaming over HTTP (DASH)
