DVB-CAS (Digital Video Broadcasting - Conditional Access System)

DVB-CAS (Digital Video Broadcasting - Conditional Access System) is a technology used by cable TV providers to control access to their content. It encrypts the broadcast stream so only authorized viewers with a valid subscription can decrypt and watch the channels. The system uses smart cards or similar devices to verify subscriber credentials securely. This ensures that premium content is protected from unauthorized access while allowing providers to offer a range of subscription options efficiently. In essence, DVB-CAS manages digital rights and access control, enabling broadcasters to deliver content securely and monetize their services effectively.
