Hi Amy.
I don't think anything's been confirmed for definite, but the Digital Spy website posted the following information recently:
The official website will host live video streams from the house, as well as recorded video highlights accessible in news reports.
For the first time ever though, it looks as if access to the feeds will be charged for. A release from C4 said: "At the time of going to press, Channel 4 anticipates that the live streaming will be available on subscription."
So .............. it looks from that as if we're going to be charged for the live feeds. I think I'll make do with E4 interactive!
