Telemundo will broadcast Spanish language telecast similar to NBC-HD. All other HD broadcast will be on USA-HD and Universal-HD, Universal Sports Basketball Channel-HD and Universal Sports-Soccer HD.
If you look in your Onscreen Guide, you will see occasional 1-2 hour Olympics programming blocks with things like beach volleyball, swimming and cycling.
But it looks like they also want to preserve the normal Telemundo programming for people who are not interested in the Olympics.
In cities with large Hispanic populations, some NBC stations have spanish dubbing on SAP alternate audio.
