2 ASI inputs, IP (up to 4 IP streams) input, 2 ASI outputs, IP output

The D2iMux is a cost effective HD/SD MPEG digital video IP stream multiplexer that transforms services from ASI and Gigabit Ethernet into a tailored transport stream ready for distribution over ASI, IP and SMPTE-310. Service components from any input can be used to create each output for true flexibility in building your own MPEG-2 or MPEG-4 services.

  • Description
  • Specifications


Once the new services are defined, the D2iMux faithfully handles all of the table processing to ensure a pristine output. With the D2iMux, you get essential control in a compact multiplexer for reliable contribution of live events, production and content delivery with distribution capability for broadcast, cable and IPTV.


Contribution: Dynamically adjust services or easily load profiles to customize the ASI or IP feeds and multiplexing functionality for live events, live production, post production and content delivery playout.

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.

Key Benefits:

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

Easily Rebrand Channels: Control the PSIP/SI branding of all your service channels with advanced ATSC table processing required for terrestrial broadcast.

Value you can count on:The D2iMux delivers a strong Return on Investment (ROI) in a compact multiplexer with proven reliability. In just minutes, you can create a custom multiplex ready for the most demanding contribution and distribution requirements.
