4-channel Scrambler with DVB-C Modulator CRT1041M-C-IP

CRT1041M-C-IP is a compact size Edge QAM Modulator with embedded CAS Crypton Pay TV Scrambler. Up to four IP encapsulated MPTS streams can be received on the device MPE input. Selective DVB-CAS scrambling of DTV programs along with address subscriber message system (CAS Crypton) let you provide efficient Pay TV business model.

Each of the streams is DVB-C modulated and up-converted to the RF Band (48-850MHz). All device control is done with a Web interface. SNMP let your NMS perform real-time monitoring and logging the device basic parameters.

CRT1041M-C-IP devices can be easily combined into a cluster to form a scalable network, are easily integrated into the Crypton Headend and are compatible with a huge number of third-party devices that support DVB-over-IP encapsulation.

Brief description of the main blocks

• DVB-over-IP MPE receives up to four IP encapsulated MPTS streams
• MPE Channel Filter arranges reception channel for one MPTS stream from IP network. That MPTS is preliminary built with third party multiplexer
• Scrambler CAS Crypton selectively scrambles DTV programs within the stream and provides conditional access in accordance with CAS Crypton specification
• DVB-C Modulator converts input MPTS stream to DVB-C modulated signal (IP to DVB-C Modulator)
• RF Up Converter shifts pair of adjacent (8MHz offset) DVB-C modulated carriers to RF Band (48-850МHz)
• Control 100Mbit Ethernet port provides physical connection for device control over Web and CAS Crypton interconnect for SMS provision
• SNMP 100Mbit Ethernet port is dedicated to SNMP agent providing NMS with real time information for monitoring and logging the device basic functionality
