The D2Flex5220 is a powerful 1/3 rack unit MPEG video multiplexer and IP network gateway that creates digital video transport streams from any service component over ASI and Gigabit Ethernet. Advanced DTV channel branding, video processing and optional PSIP data insertion serve to create a channel lineup that viewers are looking for.
Transmission of high quality video with low latency across the public internet is supported with the Secure Reliable Transport (SRT) protocol.


Public Internet Transmission: Leverage the power of a Secure Reliable Transport (SRT) to deliver broadcast quality video with low latency across the public internet.

Distribution: Easily aggregate services from many sources and local programming with service processing and preparation for transmission over satellite uplinks, terrestrial broadcast, cable and IPTV.

Regionalization: Regionalize multiplexes at head-ends and transmitter sites with service add/drop and advanced channel branding.

Key Benefits

Internet streaming with SRT: The D2Flex5220 features the standard Secure Reliable Transport (SRT) that provides end to end security and optimized streaming performance across unpredictable networks for the best quality video possible. The integrity and quality of the video is maintained by accounting for packet loss, latency, jitter and dynamically adjusting for bandwidth between each endpoint. Now you can reliably deliver low latency video over any network including the public internet.

Easily Rebrand Channels with EPG:  Set the major and minor channel numbers on each output stream and pass through or regenerate the necessary PSIP tables. The optional D2Guide can insert an Electronic Program Guide (EPG) from services like Titan TV and Gracenote (TMS) or from a spreadsheet with programming for the next several weeks so your customers can find the programs they want.

Optimize Transport Bandwidth: Get the most out of your transport by creating up to 8 independent Multiple Program Transport Streams (MPTS) from all of the service inputs. Satisfy demanding bandwidth constraints by removing unwanted elementary streams like secondary audio or even drop complete programs.

Full Duplex IP Video Gateway: The D2Flex5220 can remultiplex up to 8 streams from ASI or GigE and create 8 independent IP output streams with Forward Error Correction (FEC) compliant with SMTE 2022-1/2.

Emergency Alert Insertion: Quickly inform viewers of emergencies by inserting EAS into all the programs of your ATSC digital transport stream with the optional D2Alert.
