The 7881IRDA-H264HD-LB is the basis of a professional platform for receiving, demodulating and decoding digital DVB-S/S2 satellite signals. With a compact, modular form-factor the 7881IRDA represents one of the highest density and most flexible solutions in the industry. The 7881IRDA-H264HD-LB 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 IRDA to be packaged in the traditional IRDA formfactor, 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. The 7881IRDA 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 7881IRDA utilizes an advanced decoder with support for both MPEG2 and H.264/AVC, SD or HD encoded signals, optionally up to 4:2:2 10-bit.
In addition to a quad-RF input, the 7881IRDA also provides inputs for IP and ASI signals, making it a future-proof, universal reception platform for signals delivered over satellite, fiber and other network media.
Monitoring parameters such as EsNo ratio, RF power, BER and packet errors present a convenient solution for broadcasters and cable companies who wish to not only receive, but also remotely monitor signal quality. Also. These parameters as well as Full monitoring and control of the IRDA are relayed over SNMP, for convenient remote access using Evertz own VistaLINK® PRO SNMP monitoring and control package. Additionally, low-speed data support is provided for in-band control.
For applications requiring decryption, the IRDA provides a slot for installation of a customer supplied conditional access module. DVB-CI compliant conditional access modules and formats are supported.
