DVB-T DVB-H Terrestrial Modulator


Broadcast Quality, SNMP Manageable, Frequency Agile COFDM (DVB-T) Modulator with DVB ASI input via USB-2 or ASI and IF and RF output for single and Multi Frequency Network Applications. Field selectable 6, 7,or 8 Mhz channel bandwidths. Optional DVB H firmware.

Features

  • DVB-T Terrestrial Modulator with integrated RF up-converter Option for DVB-H compliance to address mobile receivers Broadcast quality
  • Supports hierarchical input mode

  • High and Low priority MPEG-2 stream inputs

  • Separated modulation schemes for each input

  • Support both Frequency Network modes:
    - MFN and SFN modes
    - Seamless switching (SFN mode)
    - External synchronization (10MHz and 1pps GPS) for SFN

  • Enhanced ASI input stage - on each priority:
    Redundant ASI inputs ( 2x ASI inputs per priority, automatic switching)
    188/204 bytes per packet accepted (burst/continuous)
    FEC processing and error correction
    PCR restamping
    TS bit rate adaptation

  • High end processing of input MPEG TS before modulation:
    MIP processing
    NIT automatic update
    TPS Signaling
    Static/dynamic delay insertion

  • Integrated agile RF up-converter
    1x RF UHF output

  • Remote control
    10/100bT ethernet interface
    Embedded TCP/IP server
    Control & Command client software

  • Compact equipment
