4 In 1 MPEG-4 HD Encoder With SDI Input
4-Ch MPEG-4 AVC (H.264) HD Encoder
1: Support 4 CH HD encoding
2: Support SDI input
3: Support AAC
Product Overview
GN-1864 is a MPEG-4 AVC HD encoder, a flagship HD encoder launched by GOSPEL. It is designed to perform high definition MPEG-4 AVC compression encoding up to four channels of SDI and (or) HDMI digital A/V signals simultaneously. Also, it supports audio encoding of MPEG-1 Layer II and AAC, and outputs transport streams through ASI/IP interfaces after multiplexing.
GN-1864 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. This equipment can be used for A/V signal source encoding of a DTV head end system.
