SPECIFICATION
MPEG2 demultiplexing-decoding functionality
  • The extracted MPEG2-TS from the COFDM Front-End or from the ASI input is analyzed according to TR 101 290
  • The elementary audio and video MPEG stream selected by the user are uncompressed
  • The video signal is then converted from digital to analog and coded to the color standards: SECAM, PAL
  • The composite signal is output on a BNC connector at the rear of the equipment.
  • Simultaneously the RGB color components are provided on a D-SUB /HD 15 pins (VGA type) connector
  • The audio channel is output on XLR 5 type connector
RF Analysis
  • BER pre Viterbi correction
  • BER post Viterbi correction
  • MER (max 33dB) ±0.5dB
  • PER (packet error rate)
  • RF input level ±1dB
  • Frequency and clock rate offsets
  • SFN delay (References Inputs for SFN modes: 10 MHz and 1 pps.)
Remote control
  • Through the ANTLAN® protocol over RS485 or RS232: a console monitor allows access to all the functions of the equipment as configuration, measures and alarms
  • Through relays: 4 user’s defined alarms and “power supply on” are available
  • Through an Ethernet TCP/IP proxy board, full remote control is available using HTTP, FTP, SNMP protocols
  • Web server is embedded
