Stand Alone Scrambler

Product Description

Product Description

NDS3701 scrambler is used to scramble the digital television signal. It 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 ECM's CP cycle according to the channel's parameter
. Send ECM to the multiplexer according to the channel's parameter
. Send CW to the scrambler according to the CP cycle period
