The BBC 2012 London Olympic "streaming" channels will be soon made available to Sky and Freesat users.
Sky have said the channels will be added to Sky guide sometime on Monday 23rd July 2012
They will be available from Sky channel 450 upwards.
Freesat have said "All freesat customers will get the 24 live Olympic channels. Just press the red Button, or go to the Olympic genre in the freesat EPG starting at Channel 150. The 24 live channels will be available from 25th July until 12th August, right through the Games. As some events finish, not every BBC Olympic channel will be broadcasting all the time so check the BBC Red Button for what's on when."
Although there is no clear indication as to when exactly they will appear on Freesat, but sometime 23rd or 24th would be good, since it starts on the 25th (days before the opening ceremony!)
For other satellite recievers, the channels will have to be manually added to your channel list
