I can't speak for products outside of the U.S., but for what it's worth, HD digital tuners have been available on TVs for several years.
You might try calling the Samsung customer service center in your region for further clarification on your specific model.
with world cup I just discovered that I'm able to see HD channels with my LED TV UE46B8090XWXZG (german market).
means my TV already have new HD DTT on board?
just wondering if is also CI+ ready....does anybody knows?
