Product Description


OTV-1400A ASI IP Bidirectional Multiplexer is Dibview's latest multiplexing device for digital TV broadcasting head-end system with TS output through 4 bi-direction ASI and 3 bi-direction IP ports. It can multiplex up to 4 ASI and 513 IP input to 5 MPTS, and the amount of ASI output should based on ASI input (ASI port can be used as input or output).


OTV-1400A ASI IP Bidirectional Multiplexer has the functions of supporting auto-generation of PSI/SI information, PID re-mapping, service filtering and PCR adjusting. In conclusion, its high integration and cost effective design make this device widely used in the CATV Broadcasting system.

Key Features:

  • Low power consumption, rack-mount design

  • ASI in/out: max 4 ASI input/output thru 4 bi-direction ASI ports (ASI direction can be defined as input or output manually)

  • IP input: 513 IP in over UDP/RTP (256×2 IP in thru GE1 and GE2, 1 IP in thru Data port)

  • IP output: 5 IP (MPTS) out over UDP/RTP (4 MPTS out thru GE1 and GE2, 1 MPTS out thru Data port)

  • Support all input programs output bypass

  • Support accurate PCR adjusting, PID filtering, re-mapping and PSI/SI rebuilding and editing

  • Huge buffer memory for saving the overflowing code stream
