What technology allows digital set-top boxes (STB) to receive authorization for encrypted content?

The technology that allows digital set-top boxes (STBs) to receive authorization for encrypted content is known as addressable technology. This involves a system where each set-top box is individually addressable, enabling service providers to send targeted authorizations or decryption keys directly to specific devices. This ensures that only authorized users can access encrypted content, making it a crucial component in managing digital rights and content distribution.

Addressable technology also enhances the user experience by allowing for personalized content offerings and targeted advertising. This capability differentiates it from broadcast technology, which transmits the same signal to all users, or analog technology, which does not support encryption and targeted delivery. Satellite technology can deliver content to set-top boxes but does not inherently include the capability for individual authorization without an addressable system. Thus, addressable technology is essential for securely managing and delivering encrypted digital content to end-users.
