Standard Features:
Two modes of operation :
- USB Mode : In this mode the device works as a USB based DVB-T/H/C modulator, exactly the same as Alitronika's AT2780USB device,
with the TS being modulated coming from the Harddisk of the PC or from an external source via DVB-ASI or DVB-SPI inputs
- IP Mode : In this mode the device operates as a STAND-ALONE DVB-T/H modulator,
with the TS being modulated coming from an IP source.
IP Mode
Input & Outputs
DVB-IP.
RF & IF Outputs.
DVB-ASI output for monitoring the modulated TS file.
Encapsulation of the TS data for Ethernet uses IP and the User Datagram Protocol (UDP), with Real-time Transport Protocol (RTP) encapsulation and COP3 FEC. Dedicated hardware performs the encapsulation, which maximizes the throughput and latency. The device can accept traffic from Ethernet network and recover TS data. For RTP encapsulated data, the device incorporates buffer to absorb network jitter and correct for packet reordering and packet duplication. COP3 FEC-based lost packet recovery is available. For multiple TS interfaces, the AT60IP, individually maps each one to a specific UDP/IP socket (a combination of IP address and UDP port). All other encapsulation parameters can also be individually configured per TS. Network jitter correction. Supports constant bit rate ASI output. IP address assignment from DHCP server and static IP address. IP address also configurable through the web interface. Configuration for Time To Live (TTL) for Multicast. PCR, continuity counter correction. Packet time and date correction.

Accompanied by DVSStationIP Alitronika's Application Software.
Supports DVB According to Standard A1010 Rev1 and EN50083.
Modulation of Transport Stream files from USB, DVB-ASI/SPI.
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.
