De ce nu merge pe aparate decodare PVU:
CSA TS
Code:
STB<=Receive Sat Signal
STB==Extract TS(audio/video/ECM/EMM)
STB=>send ECM
Server<= received ECM
Server==Decrypt ECM and extract CSA-[DCW]
Server=>Send CSA-[DCW]
STB<=received CSA-[DCW]
STB==pass the received CSA-[DCW] to its specific CAS Hardware Decoder to decode TS Video and Audio.
PowerVU TS
Code:
STB<=Receive Sat Signal
STB==Extract TS(audio/video/ECM/EMM)
STB=>send ECM
Server<= received ECM
Server==Decrypt ECM and extract DES-ECB [DCW]
Server=>Send DES-ECB [DCW]
STB<=received DES-ECB [DCW]
STB==pass the received DES-ECB [DCW] to its specific DES-ECB Hardware Decoder to decode TS Video and Audio.
The problem with most STB's are designed with just CAS Hardware Decoder and to be able to decode Video and Audio they require DES-ECB Hardware Decoder instead. So no maters what we do with SBLC/OSCAM/FAUSTO/VPLUG they do not have the internal hardware decoder to decode a TS encrypted Audio/Video.
SURSA
Receptoarele au implementat la nivel hardware CSA iar PVU necesita DES-ECB.
Momentan ... nu se intrevad solutii.

Daca ma uit in documentatia de la STI7105: DVB/DES/T-DES/AES/Multi-2/ICAM2.2 descrambling.
Sa speram ca vor rescrie PTI la SH40.
