TV Receive Only (TVRO) Marine

Television receive-only, TVRO, big ugly dish (BUD), is a term used in North America to refer to the reception of satellite television from FSS-type satellites, generally on C-band analog; free-to-air and unconnected to a commercial DBS provider. TVRO systems rely on feeds being transmitted unencrypted and using open-standards, which heavily contrasts to DBS systems in the region.

The term is rarely used in recent times due to the general move towards pay television and subscription-based DBS services like DirecTV, Dish Network, Bell TV, and Sky TV, although it is still sometimes used to refer to receiving digital TV "backhaul" feeds from FSS-type satellites. TVRO was once the sole, and later the main means of consumer satellite reception in the United States, until the mid-1990s and the arrival of services such as PrimeStar, USSB, DirecTV, and Dish Network.

While these services are at least theoretically based on open standards (DVB-S, MPEG-2, MPEG-4), the majority of services are encrypted and require proprietary decoder hardware.
