Extensor HDMI2SDI seamlessly converts HDMI video to HD-SDI with optional downscaling, and converts stereo unbalanced audio and digital audio AES/EBU embedded audio in SDI. It supports the full range of video resolution formats and frame rates, with progressive to progressive and interlaced to interlaced downscaling available on each output. The Extensor HDMI2SDI features two 3Gb/s HD-SDI outputs that can operate redundantly or stream HD-SDI video simultaneously to two devices at identical or different resolutions. An on-screen display overlays all status information directly on the video output signal and an embedded standardized color bar pattern facilitates equipment calibration. Extensor HDMI2SDI features a lockable connector on the power supply to prevent accidental disconnection. The compact device may be placed on a tabletop or wall mounted.
