Product Overview
The GN-1846 is a multichannel H.264 high-definition encoder developed on the HiSilicon Hi3531A HD encoding chip. It can perform up to 4 high-definition and low-bit-rate audio and video encoding functions on a single board. Support 4-channel audio and video coding, encoded audio and video ES packet by TS flow through an IP channel to UDP output, in device management, support Web network management, and support for online control program upgrades.
The GN-1846 features high density, flexible and seperior performance, it provides three encoding module slots, each module with four SD, HD and FHD encoding channels, and with a maximum twelve channels of MEPG-4 AVC encoding. It supports SDI and (or) HD input options, dual DVB-ASI transport stream inputs and outputs, PSI/SI processing, multiplexing and re-multiplexing outputs over DVB-ASI and IP.
GN-1846 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.
