CABLECARD AUTHORIZATION & VALIDATION PROCESSES
• In order to activate CA service (called low-value service) and to receive Cable channel map,
"Authorization process" is needed.
* Serial number and CableCARD ID are needed.
* During this process, CableCARD reset may occur.
* After this process is finished successfully, user can navigate cable channel map & can watch
CA Encrypted services to which the user subscribes.
• In order to activate additional CP services (called high-value service), a "Validation process" is
needed.
* Host/CableCARD ID is needed.
* HeadEnd sends Validation message through OOB channel.
* After Validation message is received by the CableCARD, the user can watch CP Encrypted
services also.
