DESCRIPTION
- Combined COFDM, QAM & ATSC Modulator with VHF & UHF Upconverter, supports DVB-T/H/C, QAM-A/B/C, ATSC-8-VSB and ISDB-T.
- Re-Mux function to reduce bitrate for trans-modulation.
- Stand alone operation. No PC needed. Modulation of TS files from On Board CF or External DVB-ASI source.
- High Speed USB 2.0
- Windows Drivers + SDK & Linux Drivers.
- Accompanied by DVSStation4 Alitronika’s Application Software.
- 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,
So there is no need for an expensive high performance PC. - 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.
The 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. The device modulates the incoming DVB-ASI streams. In this mode of operation, it is possible to have UNINTERRUPTED modulations of a MPEG Transport Streams, having RF (50 to 850MHz), IF (both I & Q) & DVB-ASI outputs available at the SAME TIME, 24 Hours a day, 7 Days a week without a PC.
