DTH technology allows subscribers to directly receive over 150 television channels and programs without an intermediary like local cable operators. Viewers need a small dish antenna and set top box to access the channels. Prepaid cards are used to recharge accounts for the service. DTH provides access to more channels than local cable, has better picture quality, and can provide internet connectivity. It also allows viewers more privacy by controlling access to channels like adult ones. However, signal reception can be affected during rain and a conditional access system is required for its implementation, which can also impact advertising revenue collection.
