Re:How it might work (Score 1)

The stream that is broadcast in DVB-T is in MPEG2 - so it is just stored to disk. No conversion. It might not even be necessary to demuliplex it as it stores it ... since the player can do that at run time. Each multiplex has a handful of channels - maybe 6 or 7 TV plus around 5 - 10 "radio". A typical home user would get 3 - 6 multiplex. Remembering that this was just a demo of how things could change ... I think we will find that BBC R&D used freely available software on their Linux box. As a few people are starting to realise - this was a technoiogy demonstrator from a broadcaster's R&D centre - not an imminent product release.
