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.
Main Features
· Up to eight channels of SD encoding in 1RU;
· High picture quality in ultra low bit rate to reduce network overheads;
· Web browser and SNMP management for local and remote management and control;
· Dual Ethernet output, Supporting 1+1 redundancy
· MPEG TS-over-IP(7 x 188 Byte) output, support MPTS/SPTS mode
· Supports video encoding rate range from 1Mbps to 7Mbps
· Multiple resolutions: PAL: 720 x 576, 704 x 576, 640 x 576, 544 x 576, 352 x 576@50Hz
NTSC: 720 x 480, 704 x 480, 640 x 480, 544 x 480, 352 x 480@60Hz
· Supports VBR/CBR video encoding
· Supports simple TS multiplex with auto-generated PSI/SI
· Low power consumption
· Front panel control and LCD display
· Auto-saving of user configuration for the recovery of previous working status
· Malfunction alarm display
