7881IRD2 Series

Professional Digital Terrestrial/Cable/Satellite SD/HD Dual Modular Integrated Receiver Decoders

Interact with this product in a Layout Tool:

The 7881IRD2 series is the basis of a professional platform for receiving, demodulating and decoding digital ATSC/DVB-T/T2/ISDBTb/DVB-C/C2/DVB-S/S2 satellite signals. With a compact, modular form-factor the 7881IRD2 represents one of the highest density and most flexible solutions in the industry. The 7881IRD2 may be mounted in the Evertz 7800 series of enclosures, providing a high-density, modular solution. Options for an innovative removable front control panel and 1RU chassis also allow the 7881IRD2 to be packaged in the traditional IRD2 form-factor, while maintaining all of the benefits of modularity.

Applications include signal reception for broadcasters, cable, DTH and IPTV providers, or any other small to large head-end operators who need to receive and utilize or re-distribute satellite content, and also receive and distribute off-air local contents.

The 7881IRD2 series provides ASI and IP outputs, ideal for turnaround, transcoding, monitoring or other applications where the received signal remains in the compressed domain. For baseband output, the 7881IRD2 utilizes an advanced decoder with support for both MPEG-2 and H.264/AVC, SD or HD encoded signals, optionally up to 4:2:2 10-bit.

Full monitoring and control of the IRD are relayed over SNMP, for convenient remote access using Evertz own VistaLINK® PRO SNMP monitoring and control package.

For applications requiring decryption, the 7881IRD2 provides two slots for installation of a customer-supplied conditional access module. DVB-CI compliant conditional access modules and formats are supported.


  • Modular design, allowing flexible configurations along with easy system reconfiguration and service
  • May be mounted in the 7800FR series frames in high-density applications (up to seven IRD2 in one 3RU frame)
  • May be mounted in the 7801FR and fitted with the 7801CP control panel, yielding a 1RU IRD with removable front control panel and optional redundant power supplies, all of which are hot-swappable and may be serviced without any de-cabling required. Up to two units may be mounted in the 7801FR and used with the 7801CP, providing a dual-IRD solution in 1RU
