Dish TV came up with a new gadget.

Dish TV, India's largest DTH service provider,with a customer base of over 6 million came up with a new gadget that helps us to shift from one DTH service provider to other without changing the set top box and dish antenna.The gadget is called CAM (Conditional Access Module),which is a card that can be inserted into the set top box.
Recently TRAI (Telecom regulatory authority of India)has made it compulsory that set top box offered by every DTH service provider should have an empty space where the card can be inserted.

Advantages
