As today's home consumers are looking for entertainment choices comparable with the high quality sound and video resolution found in their local movie theaters, many people are choosing to get satellite tv. Satellite TV operates by a satellite that is stationed in space, and transmits signals picked up by satellite dishes here on Earth. During the 1980's home satellite TV began to emerge across the United States. When home satellite TV began to emerge, home users were able to view countless of channels via their satellites. This upset many corporate companies who were selling their movie and network programming via cable subscriptions. The company's then began to encrypt their programming and sales of home satellite TVs decreased. In the 1990's home satellite TV systems began to incorporate Videocypher technology that allowed the satellites to unscramble signals, allowing home users to once again access countless channels.
There are two main types of Satellite TV dishes that orbit in space. These are TRVO and DBS. TRVO satellite dishes are large and move. DBS satellite dishes are smaller and do not move. There are two main DBS satellite systems in the United States; they are Direct TV and the Dish Network. TRVO stands for Television Receive Only. These are the first satellite TV systems that originated during the 70's. DBS stands for Direct Broadcast Satellite. DBS systems are scrambled and will not pick up another's satellite programming. For example, Direct TV users will not be able to accidentally pick up Dish Network programming. Each DBS satellite TV system requires it's own receivers and equipment to unscramble their signals.
