We have known for sometime that the BBC was going to start broadcasting in HD but the details were sketchy at best. What we know now is that they will start their high-def stream on May 11. Keep in mind that this is a limited trial only and you need to be on the "list" to receive the signal. Telewest will be able to receive the signal right off the bat with Sky shortly there afterward's. Sky will start to install the necessary equipment on May 22. The programming seems limited but will certainly grow with time.
