A Duplex IP/ASI Video Gateway With SRT Protocol Arrives


D2D Technologies has brought to market the D2Flex 3000, the latest full duplex IP/ASI Video Gateway that features the Secure Reliable Transport (SRT) protocol for reliable transmission of high quality video with low latency across the public internet.

The receiving system can also regionalize at head-ends and transmitter sites with advanced channel branding, a dynamic PSIP electronic program guide and insert the critical emergency alerts (EAS) required by the FCC.

Steve Doll, President of D2D Technologies, notes that SRT provides the highest-quality by accounting for packet loss, latency, jitter and dynamically adjusting for bandwidth between each endpoint. “The transmission can also be secured with AES 128 or 256 bit encryption that is critical when using the public internet as the transport,” he says.

The D2Flex 3000 can set the major and minor channel numbers on each output stream and pass through or regenerate the necessary PSIP tables. The optional D2Guide can run on the D2Mux platform to provide dynamic PSIP data insertion from services like Titan TV and Gracenote (TMS) or from a spreadsheet with programming for the next several weeks.

The D2Flex 3000 platform can also host the optional D2Alert application, which inserts digital video from an Emergency Alert System (EAS) like the Digital Alert Systems DASDEC or the Trilithic EAS system. The D2Alert system constantly monitors the EAS system and when a valid alert is found, it is automatically inserted into all of the configured programs until the alert is complete.

The D2Flex 3000 features dedicated ASI input and output ports for full duplex Transport Stream over IP (TSoIP) conversion of up to 4 independent streams. Digital streams over IP are handled by a standard RJ45 Gigabit Ethernet port that also supports browser based management and SNMP remote monitoring with configurable traps.

The D2Flex 3000 IP/ASI Video Gateway is available in a compact 1/3 RU wide design with an optional rack mount kit from select dealers and system integrators worldwide or directly from D2D Technologies. List prices start at $1,199 for SRT turnaround, $1,999 with basic channel rebranding included, and $3,799 with EPG insertion included.
