XBT 525 Multiplexer

XBT525 SFN Multiplexer is a dual multiplexer and a dual synchronous SFN adapter allowing easy creation of DVB-T/H SFN systems.
• XBT525 MFP Multiplexer performs the following basic functions:
• GPS receiver capable of synchronizing internal time generators
• Megaframe Information Packets generation (2x – one for High Priority, other for Low priority) with internal carousel of functions
• Software interface for external carousel of MIP functions
• 16 Carousel of PSI/SI tables with variable bit rate(2x – one for High Priority, other for Low priority)
• Software interface to external PSI/SI tables generators
• Storage of internal carousels content
• Multiplexing (2x – one for High Priority, other for Low priority) of
• Multiplex Information Packets
• 4 transport streams selected between 10 physical inputs with PCR re-stamping
• PSI/SI packets from carousels
• PID filtering and re-mapping on each logical input (4x2 - four for High Priority, other for Low priority)
• Network adaptation to the exact bit rate (2x – one for High Priority, other for Low priority) according to DVB-T/H RF parameters with PCR re-stamping
• Graphical display of input TS data based on SI/PSI analysis
• Option “8IN”: Multiplexing of 8 logical inputs in a single output TS instead of 4 for 2 channels Inputs to multiplexers are:
• 8 ASI transport streams
• 1 SPI connector for multiplexer extension
• 2 RTP clients for RTP/UDP encapsulated Transport Streams on 2 different sockets on single ethernet port.
Outputs from multiplexers are:
• 4 ASI Transport Streams carrying 2 High Priority Transport Stream and 2 Low Priority transport stream
• 2 RTP/UDP Server carrying encapsulated Transport Stream for High and Low Priority on 2 different IP address
• IGMP generation
• SPI output for system extension As any multiplexer of the XBT family, it has built-in:
• Web server to dispatch a Java applet for interactive management
• Java applet tested on most popular browser
• Java applet downloadable for local execution
• SNMP server for remote control
• internal file system accessible via TCP/IP and TFTP protocols for easy remote upgrade
• ultra fast storage are for event system storage
• telnet server for access via character based terminals
• Geographical coordinates available
• Battery powered local time clock automatically synchronized to UTC
• 8 trap address for automatic alarm/monitoring
