Description

Scrambler

Brief introduction

 

JD-SCW-1100 scrambler is designed by JZ, which meet the DVB simulcrypt standard, internally embedded with control word generator, shall send fixed or alterable control word scrambling, shall scramble for input real-time video rate, and also process DVB common scrambling. The long-distance management shall be operated in the computer equipped with browser, through external network management software. Base band signal and additional data multiplexing meet the standard of ISO/IEC-13818. The interface for TS input and output is DVB ASI interface. The part connected with CA and network management support TCP/IP protocol, adopts RJ45 Ethernet interface. The scrambler shall be divided into two parts: scrambler module and network management software. The scrambler is embedded and shall receive input CA information; the network management is based on Web browser software and available for long-distance controlling and state monitoring.
