GN-1838
8-Ch MPEG-2 SD Encoder
Product Overview
GN-1838 is GOSPELL’s latest highly cost effective and high density MPEG-2 SD encoder which can perform MPEG-2 compression encoding for up to eight channels of analogue composite video and stereo pairs signals simultaneously, and then output the signal through ASI and IP interfaces after multiplexing. It supports 1+1 redundant output via dual ASI and (or) TS-over-IP interfaces, and with Web browser and SNMP management, these features make it more reliable, flexible and much more easy to deploy, in conventional or even IP-based DTV head-end systems.
