BE8500 HD/SD H.264 or AVS Dual Encoder

The Telairity BE8500 is a versatile video encoder, able to autosense either HD or SD iEnpleutcvideo formats, and automatically select a corresponding encoding mode. It combines leading-edge compression technology (either H.264/AVC or AVS) with settable encode latencies ranging from 150ms to 2 seconds. Featuring “instant on” for immediate availability, simple “two button” front panel control for quick and easy field operation, wide temperature tolerance, optional dual redundant power supplies and optional external audio inputs (AES and analog stereo), the cost-effective and reliable BE8500 addresses the critical needs of broadcasters for flexible encoding.
