Stand Alone Scrambler(DSD-5)
|
|
|
used to scramble the digital television signal. supports the
simultcrypted scrambling, embedded control word generator, fixed or
variable control word scrambling, and scrambling of the program
stream and the elementary stream.
Main Features and Option
.Support DVB hardware scrambling, high performance/price ratio
.Robust PSI/SI information analysis function, input stream error
warning
.DVB scrambling for the designated program stream or elementary
stream
.Send fixed or variable control word scrambling
.Compatible with DVB common scrambling algorithm
.Support DVB Simulcrypt interface, support 4 simulcrypt CA at the
same time (option)
.Supply exoteric CA interface
.Support ECM and EMM insertion
.Inject exterior data and information via network
.PCR correction
.DVB scrambling for the designated program stream and elementary
stream
.Support to scramble audio and video separately, suitable for using
in the operating and transmitting system where the order for content
protection is strict
SCS(Simulcrypt Synchronizer Control System):
.Set up the TCP connection with ECMG and assign one channel for
each connection
.Create the required stream in the channel and assign an ECM
Stream ID for it
.Get the CW(control word) from the CWG
.Send the CW to the relevant ECMG
.Get ECM information from ECMG
.Synchronize ECMs CP cycle according to the channels parameter
.Send ECM to the multiplexer according to the channels parameter
.Send CW to the scrambler according to the CP cycle period
