Conditional Access (CA) Conditional access system (CAS) standards are defined in the Digital Video Broadcasting (DVB) standard for DVB-CA (conditional access system), DVB-CSA (the common scrambling algorithm) and DVB-CI (the Common Interface). These standards define a method by which one can scramble a digital-television stream, with access provided only to those with valid decryption smart-cards.
