Product Overview
GN-1898 is the latest MPEG-2/MPGE-4 AVC high efficiency SD encoder.
It can perform SD MPEG-2/MPEG-4 AVC compression encoding of up to eight channels of analogue or digital A/V input signals simultaneously.
Then output the signals through IP interface after multiplexing.
This unit can be used for A/V signal source encoding of a DTV network head-end system, and it also supports WEB/SNMP management.
Main Features
