  2. Goals of CEA R7WG9 • Establish a single, detailed HTML and A/V definition for IPTV terminal devices • Support broadcasts over Internet and Home LAN. • Use existing standards (when possible) for home networking and Internet: • DLNA 1.0 (for home network) • UPnP (for home network) • HTTP 1.1 • XHTML, CSS2.1, CSS-TV • PC and TV monitor-friendly • Support many client types: cell phones to hi-def TVs. • Independent of operating system • Not in-scope: A/V broadcast and protocol format over the Internet

  3. Contributing companies to CEA R7WG9 • Philips • Samsung • Sony • Pioneer • Panasonic • Hitachi • Intel • Echostar

  4. CEA 2014 Specification Overview • CEA 2014 spec defines 4 things: • Devices: remote UI (RUI) clients and servers • Server and client interaction over the home LAN • Server and client interaction over the Internet • CE-HTML: a new browser required for CEA 2014 client devices.

  8. CEA 2014 Home Server • LAN Remote UI (RUI) server: • Discovered via UPnP • Exposes XML listings of CEA 2014 UI applications • App XML metadata includes: • Required client display and A/V capabilities for each app. • URL for http XHTML server. • Client acquires metadata and performs http-get on the URL. Internet 2014 server • WAN Remote UI (RUI) server: • Non-discoverable • Each URI is a unique app • Client performs http-get with client capability description. Server matches the capabilities or returns status code Home 2014 server

  9. web page 1 web page 2 web page web page 2 web page 2 web page A/V window A/V window A/V window A/V window A/V window A/V window CEA 2014 - Additional Features • Other client requirements: • XMLHTTPRequest • Allows clients to 'poll' for updates w/o performing whole page update • Persistent TCP Sockets • Allows Remote UI Servers to send session-context messages (text or text-encoded binary messages) • 3rd Party Notifications: • http text notifications • Polling-based for Internet • Multicast for home • Other options: • Save & Restore - defined for client and servers. • Allows users to save the 'state' of an app for later use. 2014 client (TV)
