For me, BarCamp Leeds started with Mark Sailes‘ session on TV 3.0. Mark’s session was one of my favourite sessions of the day and centred on his contention that TV needs to enter a third phase (1st phase: black & white, 2nd phase: colour). TV 3.0 is all about audience participation and analysis (this linked in with one of Tom Smith‘s irritations from his talk, that viewers can’t own and tailor their TV programming), resulting in rich metadata around programmes and films. Mark suggested one mechanism could be a collaborative highlighting and commenting method for working playing with video streams, some mechanism like Flickr Notes to add comments, a way to tag themes like “lightsaber fight!”, “Vader”. You would then be able to choose different ways of consuming the content, “I want to watch all the light saber fights involving Vader” (Mark’s a Star Wars fan).
