The Telairity BE7400 is a scalable, fully programmable, low latency broadcast encoder for standard definition video formats.

It uses state-of-the-art H.264/AVC (MPEG-4) compression technology to achieve more than twice the compression efficiency of the older MPEG-2 standard. The cost-effective four-channel BE7400 encoding platform addresses the needs of broadcast OEMs for real time performance and flexibility, and can be easily upgraded via software to add new and improved features and enhance performance.

Direct broadcast satellite operators, major TV networks, TV stations, cable companies, Telcos and post production facilities all have encoding needs. The AVClairity family of real time, high definition, H.264 video encoding software provides high quality video images while at the same time optimizing bit rates so broadcasters can maximize their channel capacity and programming.

 

Features at a glance:

Real time SD H.264/AVC encoding

Compact 1RU system for broadcast quality video encoding.

Handles 4 fully independent SD channels simultaneously, with up to 4 stereo audio programs per video channel.

Based on the fully programmable Telairity-1 video architecture. Easy software upgrades to improve quality, lower bit rates, add new options.

MPEG-4 AAC-LC audio for high audio quality at very low compressed bit rates. MPEG-1 Layer II and Dolby Digital pass-through also supported.

Fault tolerant design. Dual redundant power supplies, each with its own independent power plug. Built-in temperature sensors automatically control fan speed.

Network monitoring via SNMP for encoder status, power supply failure, and fan failure.
