Versatile BE8550 HD/SD/Mobile Encoder with integrated Orion DVB-S/S2 & DSNG Modulator

The Telairity BE8500 is a versatile video encoder, able to autosense either HD or SD inputs, and automatically select a corresponding user-selectable HD, SD, or Mobile encoding mode. It combines legacy MPEG-2 SD encoding with leading-edge H.264/AVC compression technology, support for 2D and 3D formats, and the option of either 4:2:0 or 4:2:2 chroma sampling. Settable encode latencies range from 150ms to 2 seconds. Featuring “instant on” for immediate availability, simple “two button” front panel control for easy field operation, wide temperature tolerance, and external audio inputs (AES and analog stereo), the cost-effective and reliable BE8500 addresses the critical needs of broadcasters for a platform with the versatility to address any field or studio requirement.
