Media Talk and Tech Weekly from the Edinburgh International Television Festival 2011

This week's Media Talk and Tech Weekly podcasts are a collaborative affair, recorded at the MediaGuardian Edinburgh International Television Festival.

The event is the annual gathering of television bods who come together to talk through the issues that matter – but this year – as well as chats with the controllers, screenings of episodes from the new series of Doctor Who and The Killing and an appearance from Libya by Sky News correspondent Alex Crawford – the festival has got in touch with it's digital side ...

In among sessions about connected TV and Twitter, Google's executive chairman Eric Schmidt delivered the keynote MacTaggart lecture. In it he called for a restoration of science and engineering to the heart of the curriculum in schools, and hit out at Lord Sugar after his recent quip in an episode of The Apprentice where he criticised engineers for being no good at business.

Elaine Bedell, head of entertainment for ITV and executive chair of the festival, and the Guardian's head of media and technology Dan Sabbagh join Jemima Kiss to analyse Schmidt's words. We also hear what Mariella Frostrup, Steven Moffat, Alan Rusbridger and Fru Hazlitt made of the speech too.

Plus we have the controllers of the UK's big TV channels telling us all about the new programmes they'll be putting on our screens over the next few months – Jay Hunt, Peter Fincham, Danny Cohen, Jeff Ford and Janice Hadlow tell us how their channels are faring.

There's also a chat with Christian Hernandez, Facebook's head of international business development, who describes how the site is helping broadcasters analyse their audiences and create new revenues for them. Miranda Hart pops up to explain how she's braced for the move from BBC2 to BBC1 after an embarrassing incident with a chocolate member that made it's way to the BBC's head of TV.
