The GN-1846 is a multichannel H.264 high-definition encoder 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.
GN-1846 features high density, flexible and seperior performance, each module with four HD encoding channels, and with a maximum 24 channels of MEPG-4 AVC encoding in 1RU . It supports HD input options,supports Web browser 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.
