Product Description


OTV-IPM ASI/IP to RF modulator, with ASI input and output, optional modulation (DVB-C, DVB-T, ATSC, ISDB-T/Tb, DTMB) to convert Video/Audio signals into RF over exist Coax Cable distribution. It provides a best-of-class modulator platform for Digital TV Owners and IPTV operators.


The platform can change the modulation signal by software upgrade, this flexible operation can help to reduce the cost in the operation of the project. OTV-IPM supports modulation channel independent multiplexing, with DVB-T, ISDB-T/Tb, DVB-C, ATSC-T, DTMB modulation output, and each module can output different modulation signals.


By using PSI/SI technology, inserting NIT information table in WEB, ASI/IP to RF modulator series increased compatibility with terminal products in cable TV application.


This is an ideal solution used largely to Hotel, entertainment facilities, education broadcasting systems at schools and government buildings or IP Source signals convert to Cable TV broadcast environments.

Key Features:

  • High density, high quality, high performance, high flexibility

  • Max to 3 independent modulation modules in rear panel

  • Each module data input: 128*IP(SPTS/MPTS)+2*ASI in

  • Each module output 4*RF DVB-T/DVB-C/ATSC/ISDB-T/DTMB for option, that is 128*IPx3 input + 2*ASIx3 input independently in 3 modulation modules at rear panel

  • Front panel with 2*ASI independent in, 2*ASI independent out+4*RF output(8*RF option) (Note: for mode of ISDB-T RF output, there is only 1*ASI in and 1*ASI out at front panel).

  • NMS port in back module only for upgrading, NMS port in front panel for management

  • PID Remapping & Filtering, support LCN (Logical Channel Number)

  • Support PSI/SI editing & inserting, PCR correct and PCR interval adjusting

  • Superior Shoulders and Excellent modulation, quality MER

  • Low power consumption, high reliability with MTBF(Mean Time Between Failure)≦87600 Hours

  • Easy-to-Use System Management via Web
