Software B-CAS Conditional Access Module with MULTI2 decoder
ARIB, together with BS Conditional Access Systems Co., Ltd
created ISDB-S/T Conditional Access System named 'B-CAS'. Its detail of
operation is outlined in STD-B25.
With a valid subscriber card, ISO-7816 SmartCard reader, and our
software, faster-than-realtime decryption of Transport Streams scrambled using
B-CAS Conditional Access System is possible. In this system, ECM messages are
received from Transport Stream, processed by B-CAS card, and CWs for software
MULTI2 descrambler are obtained. Selected program is decrypted realtime by software. Connect this with our CapUSB for ISDB-S or ISDB-T USB
Receiver, and a complete ISDB-S/T archiving solution is available! There
are 3 modes of operation:
TSReader plugin communicates with
a local B-CAS card using standard PC/SC interface.
Card Server mode
Network-enabled TSReader plugin
communicates with a card server on LAN, which provides shared access to B-CAS
card. Up to 20 local clients can connect to one card server, providing
descramble functionality. Realtime archiving of entire region's ISDB-T or
ISDB-S mux is possible by using TSReader Professional and multiple
CapUSB or ISDB-T USB
Offline High-speed mode
Full mux archived recording is ran through a offline descrambler, which
processes the stream at over 500mbit/second depending on storage array speeds.
Decrypted program is then written to disk.
