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

CEA 2014 Specification OverviewCEA 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.

Powerful web browser with A/V windows• "CE-HTML":

• XHTML 1.0 Strict or Transitional• CSS-TV (based on CSS1) + elements from CSS2.0 and CSS2.1• GIF, JPEG, PNG, PNG (true color), PNG (zlib)• DOM2 Core/Style/events + KeyEvent + DOM2 HTML subset• ECMA-262 + "javascript" URL scheme• Extensive requirements for scaling, font, font substitution, etc.

• A/V:• Client-local or streaming• Window or full-screen• Streaming: over LAN or Internet• Architected as 'plug-in'• LAN stream formats: DLNA 1.0• Internet stream: not specified

• On the LAN:• Exposes capabilities via 'profiles'• Transmitted to server both LAN and Internet servers via http headers (also discoverable on UPnP clients)• Enables server-side scripting to match the web page to client capability.

• Pre-defined std UI profiles:example SD_UIPROF: w=640, h=480, truecolor hscroll=false, vscroll=truefont=”sans-serif”,”monospace”navigationkeys=true, numerickeys=true colorkeys=false, playcontrolkeys=true

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.

Internet2014 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

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.
