|The CEA-2014-B "Web-based Protocol and Framework for Remote User
Interface on UPnP™ Networks and the Internet (Web4CE)" standard
defines the necessary mechanisms to allow a user interface to be
remotely displayed on and controlled by devices or control points
other than the one hosting the logic.
The basic device operations are based on the UPnP Device
Architecture for UPnP networks and UPnP devices in the home. The
standard also allows the remote display of user interfaces provided
by third party internet services on devices in the home, and covers
a wide range of UI capabilities for TVs, mobile phones and portable
This standard includes mechanisms intended to enable flow of
content that might be under the control of a content protection
system, such as a Digital Rights Management (DRM) system. In such
cases certain capabilities defined by this standard may depend on
proper, parallel implementation of the appropriate content
protection system. Specification of content protection is beyond
the scope of this standard.
Note that for CEA-2014-B, the requirements previously identified
to remain compatible with CEA-2027-A are no longer required by this
specification. These requirements have been identified with the
The CEA-2014 protocol provides a structured way of accessing
consumer electronics friendly XHTML (and related) content over an
The main goals of CEA-2014-A were based on the following
a) Provide a mechanism that allows remote presentation and
control of user interfaces directed to consumer devices.
b) Handle remote UI content that may reside either:
• On UPnP UI server devices
• On Internet-based services
c) Use existing web standards for UI content (e.g. XHTML)
• Define extensions only when necessary
d) Support a variety of different consumer client devices
• STBs, TVs, mobile phones
e) Allow for dynamic interaction between Remote UI Clients and
• Provide timely, partial UI updates from a Remote UI Server
f) Allow clients to receive important UI notifications from
server devices at any time (if permitted by the user)
g) Allow for A/V functionality to be part of the UI
The main goals for the CEA-2014-B revision are based on the
a) A detailed HTML+A/V definition for IPTV terminal devices
b) Allow for downloading (protected) content.
c) Allow for controlling ownership of server resources.
d) Allow for controlling in-home network UPnP devices.
e) Allow for conveyance of parental ratings and parental rating
f) Integration of SVG (Scalable Vector Graphics) for enhanced
g) PC and TV monitor-friendly
h) Support for many client types: Cell Phones to Hi-Def TVs.
i) Operating System independence
j) Support existing standards (when possible) for home
networking and Internet:
o DLNA (for home network)
o UPnP (for home network)
o HTTP 1.1
o XHTML, CSS 2.1.
