Justar DTV Advanced Security Conditional Access System

Issuing time:2019-01-14 05:19

Justar DTV Advanced Security Conditional Access System include Justar Advanced Security CAS Head-end Software System and DTV Terminals. The Head-end Software System connects with DTV TS multiplexing and scrambling equipment, Subscriber Management System (SMS) or Business Operation Support System (BOSS), to perform tasks such as encrypting of DTV program or private services, managing DTV product, generating & transmitting management information of terminal devices and subscribers. Sensitive data and information are all encrypted by AES algorithm.  Justar Advanced Security CAS supports PVR re-entitle control & editing/broadcasting SI information.

The DTV terminals with Justar Advanced Security CAS client descramble and decode DTV program streams if an authorized entitlement of this program has been received before. The decryption of DTV information, as well as the encryption/decryption of confidential data are implemented based on the hardware-level advanced security features of SoC, certified by Justar beforehand. These terminals support dynamic program billing information processing and IPPV/IPPT functions. They also can receive and display program fingerprint carried by the bit streams, as well as decrypt, record and output program in accordance with the Usage Rues Information. The terminal can generate and save service data automatically according to service information sent out by CAS head-end.
