Description

Scrambler

Brief introduction

JD-SCW-1100 scrambler is designed by JZ, which meets the DVB simulcrypt standard, internally embedded with control word generator. It can send fixed or alterable control word scrambling, scramble for input real-time video stream, and also process DVB common scrambling. The long-distance management can 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 interfaces for TS input and output are DVB ASI interface. The part connected CA and network management supports TCP/IP protocol, adopting RJ45 Ethernet interface. The scrambler is divided into two parts: scrambler module and network management software. The scrambler module is embedded and can receive input CA information besides DVB scrambling; the network management software is based on Web browser software and is available for long-distance controlling and status monitoring.
