BE7200/7400 Multi-Channel SD Encoders

The Telairity BE7400 is a scalable, fully programmable, low latency broadcast quality multichannel encoder for standard definition video formats. It uses state-of-the-art compression technology (either H.264/AVC or AVS) to achieve more than twice the compression efficiency of the older MPEG-2 standard. The high-density multichannel BE7400 encoding platform addresses the needs of IPTV providers and other customers for quality SD images in 2 Mbps or less at a highly affordable per-channel price. Like all Telairity encoders, it can be easily upgraded via software to add new or improved features and enhance performance.
