B-CAS
B-CAS (BS Conditional Access Systems Co., Ltd.) is a vendor and operator of the ISDB CAS system in Japan. Or, the reception method (B-CAS method) that this company offers.
All ISDB receiving apparatus such as DTT TV, tuner, and DVD recorder except 1seg-only devices require a B-CAS card under regulation and B-CAS cards are supplied with most units at purchase. B-CAS cards cannot be purchased separately.
Implementations of ISDB-T and ISDB-T International (SBTVD) outside Japan do not use the B-CAS system at all as they do not employ the Copy-Once encryption method used on ISDB broadcasts in Japan. For these countries, some operators may choose to implement their own copy protection system.
