These CE-HTML pages are typically placed [[online]] and are based on a [[10-foot user interface]] for easy control from a distance. It is profiled on [[XHTML]] and associated standards with special CE-HTML extensions. [[Image:Example cehtml site.png|thumb|300px|right|Example CE-HTML page, with description]]
CE-HTML is part of the [[Universal_Plug_and_Play#UPnP_AV_standards|CEA-2014]] standard (also referred to as Web4CE<ref>http://www2007.org/posters/poster1017.pdf Web4CE: Accessing Web-based Applications on Consumer Devices</ref>), defined within the [[Consumer Electronics Association]] <ref>[http://www.ce.org/Standards/browseByCommittee_2757.asp Consumer Electronics Association: CEA-2014]</ref>.
==Features==
CE-HTML consists of the following internet languages:
* [[Ecmascript]] 262, 3rd edition<ref>http://www.ecma-international.org/publications/standards/Ecma-262.htm Ecmascript 262, 3rd edition</ref>
* [[XHTML]] 1.0 transitional/strict <ref>http://www.w3.org/TR/2002/REC-xhtml1-20020801/ XHTML 1.0 transitional/strict</ref>
* [[CSS]] TV Profile 1.0 <ref>http://www.w3.org/TR/2003/CR-css-tv-20030514 CSS TV Profile 1.0</ref>
* [[XMLHttpRequest]] object <ref>http://www.w3.org/TR/2007/WD-XMLHttpRequest-20070227/ XMLHttpRequest object</ref>
* [[Document Object Model|DOM]] level 2.0 (Core <ref>http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113 DOM level 2.0 Core</ref>, Style <ref>http://www.w3.org/TR/2000/REC-DOM-Level-2-Style-20001113 DOM level 2.0 Style</ref>, Events <ref>http://www.w3.org/TR/2000/REC-DOM-Level-2-Events-20001113 DOM level 2.0 Events</ref>, HTML <ref>http://www.w3.org/TR/2003/REC-DOM-Level-2-HTML-20030109 DOM level 2.0 HTML</ref>)
* a number of specific extensions for CE devices.
CE-HTML can both be used in-home through [[UPnP]] as via the [[internet]]. It allows the content creator to use the common and known languages in the [[World_Wide_Web#Standards|web]] to define a user interface that can be controlled on a CE device. A CE-HTML client typically consists of a [[web browser]] adapted for the CE-HTML standard running on a consumer electronics device.
CE-HTML offers specific extensions for these browsers such as :
* [[Multi-tap]] or other CE-specific alpha-numeric input support, by making use of the [[CSS3]] input-format tag <ref>http://www.w3.org/TR/css3-roadmap/ CSS3 working draft</ref>.
* media (audio/video) playout through the use of an audio/video scripting object.
* operation via remote control ([[spatial navigation]]) using the up, down, left, right and OK keys
* client capability matching - to match the client capabilities to the user interfaces that the server offers. For this purpose, each CE-HTML compliant client is making use of a capability profile. This profile, placed in the user-agent string of the client, lets the server know what part of CE-HTML is supported by the client. The server in turn transmits its capabilities in a so called "XML UI Listing" so the client can choose between the various CE-HTML user interfaces the server offers.
* user interface profiles for usage on CE devices such as a television. These are predefined capability profiles on which a CE-HTML client can base its capabilities. They define e.g. the fonts supported, screen-size of the device and the media that is supported by the a/v scripting object in the device. All profiles are based on a 10-foot user interface.
* 3rd party notifications which allow a client to poll for messages from an external server, and display these to the user regardless of the currently displayed user interface.
* a specific new [[MIME|MIME-type]] for CE-HTML content: "application/ce-html+xml".
Typical CE-HTML code looks like this <ref>http://www.ce.org/Standards/CEA-2014-A_Errata_TextOnly.pdf CEA-2014 errata</ref>:
<source lang="html4strict">

== History ==
CE-HTML was developed within the Consumer Electronics Association R7WG9 working group - consisting of a number of CE-manufacturers - to formulate an answer to the problem of displaying [[HTML]] (internet) content on a device that does not possess the characteristics of a typical [[personal computer]] <ref>http://www.celinuxforum.org/CelfPubWiki/ELC2007Presentations?action=AttachFile&do=view&target=CEA_2014_Overview.pwz CELF-2007 CEA-2014 standard introduction</ref>.
CE devices have problems displaying regular internet pages because these pages make use of:
* small fonts and images, not readable from a distance as when experienced from a TV or set-top box
* only mouse or keyboard based navigation, not navigable using remote control
* no highlight on the navigable elements so a user cannot see the element they navigate
* many non-portable browser specific extensions ([[DOM]] level 0/legacy DOM)
* no standard audio/video object implementation
* the use of proprietary - not CE-compatible - extensions such as [[Adobe Flash]]
Further difficulties with using a CE device to display internet content are caused by the fact that CE devices typically have different capabilities such as different resolutions, remote controls and [[Video codec|audio/video codecs]].
== Use ==
CE-HTML is increasingly used within other standards, such as the Open [[IPTV]] Forum <ref>http://www.openiptvforum.org/docs/Release1/Release1_1/OIPF-T1-R1-Specification-Volume-5-Declarative-Application-Environment-V1_1-2009-10-08.pdf Open IPTV Forum - Declarative Application Environment</ref>, the [[DLNA|Digital Living Network Alliance]] (as of version 2) and [[HbbTV]].
Some research suggests that CEA-2014 (of which CE-HTML is an important part) will be one of the key technologies in the living room internet experience <ref>http://www.linuxdevices.com/news/NS4534279458.html World Wide Web ensnaring the living room</ref>.
There are currently a number of browser vendors and solution providers that claim to have a CE-HTML capable browser, such as Oregan <ref>http://oregan.net/oregan_media_browser.php Oregan media browser information</ref> and the Wedison project <ref>http://www.wedison.org Wedison project information</ref> which is based on [[Webkit]].
