AXE-2000 Overview
Encoder/MUX Technology
Our MPEG-2 encoder uses intelligent scene analysis, adaptive decision logic and non-linear quantization to achieve excellent quality video, even with multiple video programs and challenging bandwidth constraints. Its statistical multiplexer applies sophisticated multi-layer control algorithms to optimize encoding bit rates of multiple MPEG-2 data streams, ensuring high utilization of available bandwidth. This provides great looking images on our customer’s highest priority channels.
AXE-2000 supports a wide variety of video encoding configurations
Integrated Broadcast Control System
Beyond the primary mission of video encoding, audio encoding and building the ATSC multiplex, the AXE-2000 offers integrated add-on functions, such as video format conversion, remote monitoring, and ASI re-multiplexing. The highly integrated AXE-2000 helps to shrink rack space usage and reduce power consumption, leading to lower operating costs and a better bottom line.
Gigabit Ethernet and Optical Network Interfaces
The AXE-2000 incorporates extensive networking connectivity with standard gigabit Ethernet and optional optical media connections, supporting a variety of IP ingest and transmission applications.
Network-Enabled Performance Upgrades
Adding program capacity, installing new features, and updating the performance of the AXE-2000 are simple. New firmware may be installed in the AXE-2000 from an SD memory card, from its local network or directly from a website, accessed through a secure internet connection.
Low Power Consumption and Maintenance Costs
The AXE-2000 uses a high reliability power supply with a single board computing platform that consumes less than 100W in operation. Network- based remote monitoring, diagnostics and management helps station engineers confidently manage multiple broadcast sites in different locations.
Multi-Channel MPEG-2 Encoder
