Scientific co-ordinator Lyndon Nixon (MODUL University) took the opportunity of the last month of the LinkedTV project to give a presentation during the EBU Broadthinking event about Linked Television and its offer to European broadcasters to provide added value links from their TV programming to Web content. LinkedTV is now looking at industry uptake of its complete solution and was pleased to have the opportunity to talk to an audience of largely European broadcaster members of the EBU.
Dr Nixon focused on how TV viewers have companion devices with them while watching and turn to those devices when they are interested in finding out more about something in the TV programme. Indeed, surveys show 25-40% of viewers do this at least occassionally. The problem is the lack of descriptive metadata about what is IN a TV programme and the disconnection between available metadata and external apps to use that metadata means viewers turn to third party sources outside of a broadcasters editorial control (Google, IMDB..) or are left frustrated if they can’t even search (e.g. who painted a painting when one doesn’t know the painting’s name?).
LinkedTV addresses this by providing concept and scene level information about TV content to applications that can be on the viewer’s companion device synced to the TV playback, offering instant and intuitive information gratification – under the broadcaster’s control. While a Web based implementation is already prototyped in the project, Dr Nixon also turned to bringing Linked Television to broadcast TV. The HbbTV specification has taken a significant step in enabling this type of added value enrichment service in its v2.0 release this year, with support for references to fragments of a DVB broacast stream (using the Media Fragment URI specification already used in LinkedTV) and synchronisation between TV and companion screen content (implemented by the Multiscreen Toolkit in LinkedTV). Broadcasters still need to consider the identification and annotation of TV programs beyond the EPG level, which LinkedTV can support with a set of rich analysis and annotation tools, as well as the added value to provide viewers with links to other content alongside TV, whether on a mobile companion app or a future HbbTV 2.0 app, which they can produce and check using LinkedTV’s enrichment services and Editor Tool.
In our view, the traditional reticience of broadcasters to give viewers the means to browse elsewhere on the Web “away from their content” needs to give way to embracing Linked Television as an opportunity to retain viewers with a more satisfying TV experience, win new viewers and promote archived or long tail content anew:

On 25 and 26 February, LinkedTV partners Noterik and RBB participated in an EuropeanaSpace workshop in Berlin. We were able to use the MultiScreen Toolkit to develop a small app to view a tour of the Berlin wall on a TV screen, with a smartphone serving as a remote control. Viewers can click a link on their phone, that acts as a second screen, after which the Berlin wall tour is loaded on the main screen (TV). Other participants were impressed at how we were able to use our toolkit to build a working multiscreen application in a relatively short time. Together with Sound and Vision we were able to add links to related content which become available to viewers on the second screen while the Berlin wall documentary plays on their TV by using their Editor Tool – taking an activity which today requires building dedicated applications and making it quick and simple for editors thanks to the support of the Multiscreen Toolkit (see also the Showcase) to handle the enrichments created in the Editor Tool (see also the Showcase). The whole experience showed the value of the LinkedTV technology workflow, giving broadcasters eased access to enriching their TV programming with other content and handling its delivery synchronised across screens to their viewers.

See and hear Linked Television at next month’s EBU BroadThinking 2015 event!
With the recent launch of HbbTV 2.0, the SmartTV standard for broadcasters to deliver Internet based services alongside their broadcast programming, this is the perfect moment for the LinkedTV project to show broadcasters its innovative technology solution to analyse and annotate TV programs. LinkedTV enables TV enrichment, i.e. temporal segments of programs may be linked to related content from the Web about the topics and objects that occur therein. Combined with HbbTV 2.0, broadcasters can offer this added value content as part of their existing broadcast channels and viewers can access and browse enrichments on a connected second screen without needing to download any applications or purchase any additional hardware.
LinkedTV will present in the Application Showcases slot on 18 March 2015 under the title “Linking the Web seamlessly with broadcast TV: issues and lessons learnt”. This talk will reflect on the issues we experienced in implementing Linked Television for broadcast TV and how HbbTV 2.0 can facilitate broadcasters in offering Linked Television.
On 12-13 February 2015 LinkedTV participated at the EuropeanaTech Conference in Paris with its contribution on LinkedCulture: linking related art objects with a cultural heritage TV program using the Europeana API.
LinkedTV works on synchronized delivery of Web content related to objects and topics present in a parallel online television program, which we call “Linked Television”. An “ignite talk” (slides below) explained our LinkedCulture prototype which enhances the Dutch TV program Tussen Kunst et Kitsch (with a similar format to the BBC’s Antiques Roadshow) with links to art objects from Europeana similar to the art object being discussed in the show, displayed and browseable on a second screen such as a laptop or tablet alongside the TV viewing. A poster explained the technical developments of the LinkedTV project which make LinkedCulture possible.
Thanks to Johan Oomen for giving the talk, Lyndon Nixon for accompanying the poster and Lotte Belice Baltussen for continual support!
In order that the LinkedTV Platform is able to produce rich metadata descriptions of ingested video, LinkedTV has been working on providing a wide range of multimedia analytics techniques to fragment video, label fragments with concepts and extract textual metadata from audio and image. These techniques have been combined into a single Web service which is available to the Platform via a REST API. A new video has been produced to describe the latest version of this Web service covering methods for chapter and topic segmentation, scene and shot detection, concept extraction and audio processing. For more information or access to these multimedia analytics capabilities, please contact our project partner CERTH-ITI (Evlampios Apostolidis, apostolid AT iti DOT gr).
LinkedTV is pleased to announce an extension to the submission deadline of our third international Linked Media workshop to January 31!
Taking place on May 18, 2015 it is co-located with the globe’s most important annual Web conference, WWW 2015, this time in Florence, Italy.
LinkedTV supports the so-called principles of Linked Media, which are to publicly publish online multimedia descriptions in a semantic and structured fashion so that Web agents may be able to retrieve and re-use online media in new applications and services. The workshop will give researchers and practitioners the chance to present and discuss developments in this domain, whether annotation models for online media, retrieval and re-use of online media, or application and service innovations and business opportunities for Linked Media.
