£968.40 £1,162.08

Product Overview

This converter caters for a broad range of applications, supporting DVB-T/H/C (QAM-A/B/C ), ATSC 8-VSB, and ISDB-T, all with a VHF and UHF up-converter. The hardware connectivity includes fast USB 2.0, serial RS232 control port, IF & RF outputs, and DVB-ASI I/O. 


Key Features:

  • Re-Mux function to reduce bitrate for trans-modulation.
  • On board Compact Flash Memory to play Transport Streams without a need for an external source.
  • Stand alone operation. No PC needed. Modulation of TS files from On Board CF or External DVB-ASI source.
  • Windows XP, Vista, Windows 7 & Windows 10 Drivers + SDK & Linux Drivers.
  • Supports DVB According to Standard A1010 Rev1 and EN50083.
  • Modulation of Transport Stream files from Harddisk.
  • Modulation of Transport Stream from the ASI input.
  • All modulation processes are carried out by the hardware so that there is no load on the PC processor,
  • Supports Burst or continuous modes, 188 and 204 packet sizes.
  • Bitrates:
    • DVB-T/H : 4.98 MB/s to 31.67 MB/s. 
    • DVB-C : 14 MB/s to 65 MB/s. 
    • ATSC : 10.76 MBaud to 19.30 MBaud.
    • ISDB-T: 416 KB/s to 16.85/MB/s
  • Input:
    • DVB-ASI input. 
  • Output:
    • RF Output.
    • IF ( I & Q ) Outputs.
    • DVB-ASI output for monitoring the modulated TS file.
  • Modes of operation:
    • USB Mode: In this mode the AT3780USB operates just as a standard USB based device. The Modulation and IF/RF parameter can be set via the application software, DVSStation4. The Transport Streams could be entering the device via the USB interface or via an external DVB-ASI source. A Re-Mux function could be used to Filter out unwanted PIDs to reduce the bitrate of the TS file or the Incoming DVB-ASI Transport Streams.
    • Stand Alone Mode: In this mode the device no longer requires a PC for its operation. Any Transport Streams from the DVB-ASI input is modulated according to the parameters set by the user. The modulation, IF & RF parameters are stored on the one board memory of the AT3780USB. These parameters could be changed by the user at any time via the USB or RS232 interfaces.If there are no incoming DVB-ASI streams, the device modulates from the TS files recorded on its ON BOARD COMPACT FLASH memory.


Targeted for Digital Video Professionals, Sophisticated End Users and OEMs the AT3780USB is an ideal solution for a number of applications such as:

  • Development Tools for DVB-T/H/C Receiver R&D.

  • IP to DVB Gateway.

  • DVB-T/H/C & ATCS Transport Stream Generation.

  • Stand alone COFDM ( Terrestrial ), QAM ( Cable TV ), ATSC 8-VSB & ISDB-T signal generator for Test & Validation.

  • Demonstration and Trade Shows.

  • DVB-T/H/C & ATSC output for OEM product.


DVSStation3/4/IP: Alitronika devices are supported by DVSStation3/DVSStation4 or DVSStationIP, Alitronika's free Transport Stream Player, Recorder, Analyser and converter application software.
