Things have probably changed since I last talked to my friends at a large state radio/tv broadcaster, but for long haul they used either MADI over fibre, or AES50 into boxes from NetInsight along with SDI for the video feeds. This works so well that you can put the input/output converters in a venue hosting a live music and do the program audio mix in a control room at broadcast HQ 100s of kilometers away.
