The mechanism, which takes care of the conditional access.
Actuator
A motor system that drives a motorized multi-satellite dish antenna.
Additional Outlet (A/O)
Receivers other than the primary one can be connected to the dish allowing other televisions in the house to be on different programs than the one connected to the primary receiver. An A/O also refers to a convenience outlet where there is not another receiver and the television will show the same programs as the television connected to receiver.
Alternative Audio
When a program offers more than one audio channel, customers can take advantage of that using the alternate audio feature on the satellite receiver system. There are two types of alternate audio programming: Secondary Audio Programming (SAP) and Multiple Audio Programs. SAP is a standard TV feature. Multiple Audio Programs deliver a set of audio selections with a specific program on each audio channel.

Dish 500
A multi-satellite dish used to receive Dish Network programming. Some programing for Dish Network is only available if you have a Dish 500 dish or a 2nd single satellite dish pointed to the 110 satellite for Dish Network. The Dish 500 dish is used to receive simultaneous satellite signals from the 119 and 110 satellite slots. The use of the number 500 is misleading. While the multi-sat dish can technically receive 500 channels, most of those channels are local networks from other cites. Since you can't subscribe to those channels you do not have access to 500 channels.
