I spotted the BBC’s multicast pages a while back. TV streaming looks to be running on a trial basis, and it’s entirely the BBC’s choice who does and does not get onto the trial, but radio services appear to be open to all.
It looks pretty neat in an under the hood offering no major differences to the user experience sort of manner, but my ISP doesn’t have the appropriate IP multicast functionality available to customers yet.
So I can’t try it. Can anybody else?
