DTH

DTH (Direct To Home), it would use satellite (DVB-S or DVB-S2) to transmit pay-tv signal directly to the final subscribers.

In DTH,

1. The operator would use CAS to scramble the pay-tv channels
2. The final subscriber would use DVB-S/S2 STB to receive the pay-tv channels
3. The operator would use DTH SMS to manage and control the entitlement.
4. By using CAS, DTH operator could calculate and count how many subscriber he has. Then easy to talk with the Advertisement Sponsor.
