CE-HTML provides a standardized structure for virtual keyboards and remote user interfaces on consumer electronics. It has been implemented on devices like set-top boxes, smartphones, and smart TVs from manufacturers like Motorola, Philips, and LG. Protocols like CEA-2014 and NotifSocket enable dynamic updates and event handling for remote user interfaces across multiple connected devices.

3. Motorola: Interactive Video Delivery
- Problems and Solution
Problems:
Video delivery to different devices
Display capabilities (e.g. resolution, overlay)
A/V capabilities (e.g. MPEG2, MPEG4)
User input (keyboard)
Interaction with UI for video delivery
Standardized A/V control interface
C/S interaction: push vs. poll, in/out session notification
Media and UI mobility for seamless experiences
Standardized protocol required
Solution:
CEA2014 based Remote UI technology and standard
Defines necessary mechanisms to allow a UI & content to be hosted, located (on
server), and displayed on and controlled by remote devices.
It provides a structured way of accessing CE friendly content (in CE-HTML).
CEA-2014 is not just about UI, but interacting with UI for video delivery
Superior to other standards such as RVU which transmit the UI in bit-maps

7. CEA 2014 communcation
The CEA 2014 framework lets a user interface be
remotely displayed on--and controlled by--devices or
control points other than the hosting device. The most
well-known UI update technique, XMLHttpRequest, is
difficult to adopt in an audiovisual home-network
domain, according to Samsung.
Samsung researchers apply a plug-in object,
NotifSocket, for dynamic Web UI updates using a
persistent TCP connection to support burst event
notifications. NotifSocket can share event notifications
whenever a UI server needs to inform the UI client of a
change of state or event.
CEA 2014 now stipulates that XMLHttpRequest be
defined for simple UI updates over the Internet, while
NotifSocket is mandated to transfer burst UI updates.

9. RVU protocol
The RVU protocol (RVU=DLNA+RUI) is a Application
Layer protocol, is intended to allow an RVU enabled
client, such as a TV, to receive a pixel accurate
display of the User interface available on an RVU
server.
• The RVU protocol has been
developed with a focus on
passing broadcast video
coming from a Multichannel
video programming
distributor through a
residential gateway or
dedicated media server to
other consumer electronic
devices in the home.
• However the protocol has a
much broader applications
that just this.

10. RVU alliance
There are 5 founding members: Broadcom, Cisco Systems,
DIRECTV, Samsung Electronics and Verizon. (2009/8) ->
2010/12 18 promoter members + 16 contributor members
RVU can provide more than 19.1 million DIRECTV subscribers with
the ability to watch live broadcast and stored content from their DVR
on Samsung smart TVs, without the need for additional set-top
boxes.
The published aims of the RVU Alliance are to
expand the use of the RVU Protocol to enable
users to:
Receive the same experience at every TV
through the same look and feel
Provide access to high-definition programming
from any TV in the home
Record and playback HD programming from any
TV in the home
Access to personal media content (e.g., videos
and photos) from any TV in the home
Interact with weather, enhanced sports, and
other interactive applications from any TV in
the home
Access content available on more devices
(including personal media players and PCs)
