Product Overview
Gospell’s GN-1858 is the most powerful and full-featured broadcast encoder on the market today. It incorporates the state-of-the-art hardware compression technologies to deliver multi-standard, multi-profile and multi-channel capabilities for cable, satellite, terrestrial and OTT broadcast applications.
The GN-1854 features versatile functions and compact structure in 1RU chassis, provides up to four channels MPEG-2 and MEPG-4 AVC encoding for both SD and HD programs, available in dual-channel or quad-channel SDI and (or) HDMI input options, dual DVB-ASI transport stream inputs and outputs, PSI/SI processing, multiplexing and re-multiplexing outputs over DVB-ASI and IP interface.
GN-1854 supports Web browser and SNMP management for local and remote management and maintenance, which can greatly reduce the management time, as well as enabling lower operating expenditure (OPEX) for operators.
