The EBU was invited to organize a Session at the IBC Convention, in Amsterdam in September 2010.
The plan was to identify and discuss the 'hottest' problems in broadcasting today and have broadcasters and manufacturers both put their sides of the arguments. The Session was 'Don't touch these issues - they're too hot!'
For sure, the issues and the positions of broadcasters and manufacturers were clearer at the end of the session. But, we couldn't solve absolutely all the problems in three hours.
The first part of the Session looked at broadcasting itself. The Second part looked at programme production.
So, what are the thorny ones? For broadcasting, they must include 3DTV, hybrid broadcasting, and digital radio's future. For programme making, on the slate are IT programme production, HDTV production, and the transition to 'loudness'.
Broadcasting 
Is 3DTV a real partner for HDTV or just a fashion? The truth is that we don't know yet. Can the full promise of hybrid broadcasting be fulfilled when there is such a large number of alternative systems being developed independently? It seems somewhat unlikely, though having some common elements may help. For the future of radio, maybe we should look to 'hybrid broadcasting', which will give the user both broadcast and Internet radio.
Programme Production
For IT programme production, some broadcasters have made a successful transition by taking into account both the technical and human sides. HDTV programme production in its 1080p/50 form is a great investment somewhat held back by equipment costs. For Loudness everything is in place except worldwide agreement on the exact meter settings to use, but since the differences are small we can hope.
The format and the Session proved successful, and the main problem was shortage of time to 'put the world to rights' on these issues. Maybe next year?
