GN-1886B
4-Ch MPEG-2/ MPEG-4 AVC SD Encoder
Product Overview
GN-1886B is GOSPELL’s first universal MPEG-2/MPEG-4 AVC high efficiency SD encoder. It is designed to perform MPEG-2 and AVC compression encoding up to four channels of analog input A/V signals. GN-1886B adopts redundant transport stream output, via both TS-over-UDP and ASI interfaces, and also Web / SNMP- based management can be introduced for convenient management and maintenance. These outstanding features ensure a high quality and reliable MPEG-2 and AVC signal source encoding for DTV head end system applications.
