COL52122D ISDB-T multiplexer is a TS re-multiplexer developed to adapt Japan and those South American countries such as Brazil and Argentina. It supports 2 separate multiplexers which are fully complying with ISDB-T standard. This multiplexer can transfer the head-end single program and multi-program to ISDB-T standard TS as required. Additionally, it also supports PSI/SI table editing and generating, single frequency network and IIP packet editing and inserting. What’s more, the ISDB-T multiplexer can support up to 6channels input and 2 channels output, the transmission mode is compatible with hierarchy. User can upgrade and control the multiplexer system online through network.


  • SPTS and MPTS code stream multiplexing
  • PSI/SI information editing and generating; descriptor data inserting
  • PCR correction and PID re-mapping function
  • NMS supporting, keypad parameter setting
  • Network long-distance upgrading function
  • Two groups separate output
  • Huge buffer, suddenly code stream resistance
  • 188/204Byte transmission stream packet
  • Fully complying with ISDB_T and ISDB_TB standard
  • Supporting hierarchy transmission
  • Supporting each kind of table’s user-define in its transmission layer
  • External 1PPS and 10MHz inputting; supports SFN
  • Separately set the parameters such as time delay for each device when it works as SFM mode
  • Section receiving
  • Number of segments, encoding code rate, modulation mode, time domain interlacing length for each layer and be set separately
  • IIP packet editing and inserting
