Web on TV -Browser, Widgets, Applications. Where do we go?

Workshop WEB TV, LFM NRW, 29.9.2009

Competence Center FAME Fraunhofer FOKUS

Web on TV – Is there a single solution for representing services and applications on a TV? Currently various solutions using Web technologies are or will be available on TVs:

– Open IPTV Forum DAE / HbbTV - CE-HTML– Yahoo! Widget Channel– Panasonic VieraCast– Sony Applicast– JavaFX for TV– Opera TV Widgets– W3C (TV) Widgets– Microsoft Mediaroom– HTML 5

AppliCast™

Opera widgets


Key statement

There won’t be a single way or technology to represent Web content and Web based services to the user!

Widgets / Packaged Applications will play a key role on service representation on the screen and on application deployment because of easy deployment and offline availability

Just the full integration of Web, content and telecommunication services will enable a true convergence

Ongoing developments in the Web community (HTML 5) must not be forgotten


The Open IPTV Forum DAE /HbbTV – A Declarative Application Environment for TVs

CE-HTML (CEA-2014) as common ground Extensions towards interaction with Live Broadcast Interaction with standardized Telco services possible – IMS/NGN Currently extensions with W3C widgets are under discussion for both the OIPF DAE as

well as in HTML 5 proposed in OIPF as an additional

technology for presenting content and services


W3C / DAE (TV) Widgets Widgets are persistent web applications that can often replace cumbersome native

applications and make using internet based services on a device more convenient Widgets are usually run on user agents referred to as Widget Engines. Widget engines

display widgets and in many ways mimic the behavior of Web browsers. DAE Widgets are a specialization of standard DAE applications. DAE Widgets are

inspired by (and mainly based on) W3C Widgets In the same manner as Web page Widgets can be created for multiple platforms in a

single step

Yahoo! Widget Channel

Uses embedded webkit (open Apple browser engine)for HTML support

Includes Adobe Flash 9 for flash in widgets

Offers a Widget development SDK for TV Widget Channel API provides access to popular Internet technologies such as

Konfabulator (JAVASCRIPT and XML), and HTML


Being disruptive – Yahoo! Widget connecting to Open IPTV Forum / ETSI TISPAN infrastructures

Access to:– IPTV User Profiles– Active IPTV Sessions– (Rich) Presence Information

Enabling:– Cross domain community

scenarios with full OITF clients and proprietary clients

– Allows registration and content requests

– Integration of FOKUS Smart IPTV Recommendation engine


Microsoft Mediaroom – Is the Media Presentation Foundation technically outclassing CE-HTML, Widgets and plain Web on TV?

The Media Presentation Foundation (MPF) is a new way of programming applications for the Microsoft Mediaroom Platform

Applications are built as Web applications (ASP.NET) The developing lifecycle is fully integrated

into the standard IDE (VS 2008). Application deployment is as easy as

deploying a stand alone application orweb page


HTML 5 – A more open technology for IPTV user frontends?

Today some parts of HTML 5 overlap things defined in the DAE/HbbTV specifications– <video>, <audio>– Server sent DOM events

Other HTML 5 features may be interesting– Web database, Web storage, Offline web applications

Lack of alignment with HTML 5 is one of the frequent criticisms from web people towards IPTV standardization bodies

Some suggest to consider removing the reference to CEA-2014 and align with HTML 5....

FOKUS will push this idea in the OIPF and present an initial HTML 5 DAE by November 2009


Fraunhofer FOKUS‘ key topics for Research & Development on IPTV Providing the first ETSI TISPAN Telco IPTV end-to-end test bed

– IMS-based IPTV devices and clients– IPTV Session Management Application Server, ECG, User Profile– Various value-added services implementations (TAD, Point & Click, Quiz-Show)

Open IPTV Forum (OIPF) platform and infrastructure reference implementation– FOKUS presented the first OIPF R1 reference implementation on the OIPF’s booth

at IBC 2009– 1st Interoperability Event hosted by FOKUS in November 2009– Combination of Telco, Broadcaster & CE visions

Web on TV test bed– CE-HTML & HbbTV applications– W3C Widgets on TV– Yahoo! Widget Channel

Microsoft Mediaroom Test bed– E2E Mediaroom solution available at FOKUS


Our Mission – Or how can we help you

Push Co-operation of Telcos, Broadcasters & CEs to enable real convergence between communications, Web and content– Show that Web technologies are the right approach– Convince CE’s that just with standardized telecommunication services inter-service

convergence might be reached Drive the idea of Packaged Applications (Widgets) for application deployment and

generic APIs for device and service access Build prototypes to show gaps and advantages of different kind of technologies Help CEs, Telcos and broadcasters on technology elaboration


Summary Web on TV – Is there a way to allow interoperability for the different Web on TV technologies? What do these different solutions have in common?

– Web technologies are mostly used for signaling, application logic & user interface

How to bring them together if one single technology for the UI is not enough ?– The current smallest denominator could be a common JavaScript API which

allows access to the device as well as access to network oriented services– A JavaScript API has already been defined by the Open IPTV Forum for the so

called DAE in conjunction with a CE-HTML based representation– This API provides an abstraction layer which allows access to device specific

functions as well as networks oriented services
