The post-lunch session here at EuroITV 2009 is the one that my paper is in as well, so I've refrained from sampling the fine Belgian beers available during lunch. We start with Marcelo Manzato, whose interest is in the peer annotation of multimedia content. Digital television makes it easier for user to interact with multimedia content, and this is happening for example through YouTube and similar services, of course, as well as through the proliferation of mobile devices (and the necessary adaptation and personalisation of content for such contexts).

Finally in this session at EuroITV 2009, we come to Sander Smit. His interest is in interactive networked multimedia experiences, combining TV, Web, and mobile communication. Such combination is not easy given the different histories of such technologies, and yet there is a strong push towards convergence here. Additionally, there is a push towards open service models, away from the proprietary telecom-driven frameworks of the past.

This involves the roll-out of personalisation and social networking elements in many contexts, using a variety of technological channels (Internet, mobile, broadcasting) to access available content and services. Such services themselves constitute a bundle of previously separate services, which are now combined and offered as a single service proposition to users. As a result, the service domain will become increasingly complex - which not least also means that managing information, privacy, and security becomes increasingly difficult. On the flip side, there are also substantial new opportunities for advertising.

The third speaker in this EuroITV 2009 session is Sander Limonard, who explores the potential for the development of a 'social TV' experience (and the underlying business models). The market in this area remains very immature so far, and business opportunities are still being explored; positioning models in the value network is critical, as is the link with functional architecture.

There are two major service concepts here: first, those enabling social TV experiences, which variously enable media-enriched communication within social networks (e.g. by sharing videos or tracking the co-presence of distributed users by showing whether other friends are watching the same TV channel) or communication-enriched media (e.g. by aggregating viewer ratings, persistent and shareable user profiles, or building on co-presence by adding direct communication features).

Wendy van den Broeck is next at EuroITV 2009, and shifts our focus towards interactive digital TV (iDTV). Is such technology appropriated by consumers, and how? The transition of TV is a dynamic interplay between top-down policies and bottom-up consumer interests; this takes place against the backdrop of European policy towards analogue switch-off and other technological changes.

In Flanders, for example, the analogue terrestrial signal has been switched off (which was no major problem as 97% of viewers were using cable anyway). DTV cable companies now have some 1.2 million subscribers, with another 70,000 served by digital satellite providers. Each of these providers offers additional channels, and the cable companies also provide on-demand content and additional interactive services.

The first paper session at EuroITV 2009 starts with Nils Walravens, whose focus is on the past, present,and future of HDTV in Europe. In Europe, only 20% of users currently own HD-ready screens, and only 5% view HD content at this point (so surprisingly, Australia seems to be ahead on this point - a sign of its growing prosperity over the past decade?).

HD emerged first in Japan, as a new analogue standard that was incompatible with existing TV standards; in Europe, HDTV was seen in the late 80s and early 90s as a lifeline for the television industry (struggling at the time), and there was a drive towards developing its own standards (which failed, due to poor policy decisions). European development failed to consult effectively within and beyond the industry; terrestrial transmission was impossible, not least because signal quality was poor; the standard remained analogue, not digital; and prototype devices were ugly and extremely expensive. And of course there was no attractive content which would drive user adoption. HDTV was translated as 'high-deficit television' as a result...

If this is Thursday, I must be in Belgium... I've made the (surprisingly lengthy) trip from Hamburg to Leuven near Brussels for the EuroITV (as in, interactive television) conference. On the face of it, this may seem only peripherally connected to my own research interests, but in my paper I'll be continuing to explore the theme of user-led disruptions to the conventional television model which I addressed in my MIA article and the presentation at the Australasian Media & Broadcasting Congress last year.

We start with a keynote by Rich Ezekiel, Director of Yahoo! Connected TV. He begins by outlining Yahoo!'s successful experiments with TV widgets. This responds to changed user expectations for television, which are driven not least also by phenomena such as increasingly powerful DVRs, video on demand, growing Internet connectivity in TVs, a proliferation of TV channels (whose content is no longer identified through electronic programme guides, but through a search logic), and substantial changes to the economics of content.

Hamburg.
Normally I tend to blog more when I'm travelling - but this trip is so packed full with conferences and events (not to mention the need to keep up with my regular work) that I'm hardly finding any time to write at all. So, just a quick note to say that more videos from the next09 conference at the start of May are now online, including interviews with a number of the keynote speakers conducted by conference media partner Sevenload (a YouTube-style German videosharing platform).

Here's me, speaking (in German) to Olaf Kolbrück from the magazine Horizont.

The final speaker today at COST298 is Maria Bernschütz. She takes us back to the emergence of the digital individual - identity emerged with the emergence of ID photos in the mid-1800s, but it was determined by the photographer; today, users are able to edit their online identities, photoshop their images, and otherwise control their online presence. So, what practices are in use here, especially by youth? Maria examined this in the context of the Hungarian sites MyVIP and iWiW.

The next speaker at COST298 is Kresten Bjerg, who points us to problems in the health system. How can daily diaries created using the Phenomenalog software be used to track personal health information, for example? What role does telemedical monitoring play? How can they be connected?

This requires a consideration of how such interfaces model the doctor/patient interface, and how and whether personal information entered by the patient is transmitted to third parties. This is largely also a problem of psychology (in patients and their caretakers), and of developing such systems with patient needs and abilities in mind, rather than based purely on medical practitioners' needs or on technological possibilities.

The next speaker at COST298 is Constantin-Bala Zamfirescu, whose interest is in developing Group Decision Support Systems. These have traditionally be implemented in physical infrastructure developments, such as 'situation rooms', bringing together decision makers and information in the same physical space, but can now also be turned into virtual spaces. Performance of GDSS is dependent on software configuration and instruction.

A GDSS is commonly used over a number of phases, for example from data gathering to situational awareness. Ideally it presents a solution space (possible solutions to a problem) within a larger search space (including all available information); this creates a great deal of cogitive complexity.
