Extensor SDI2HDMI seamlessly converts a HD-SDI video to HDMI with optional downscaling, and converts embedded audio in SDI (up to 4 pairs) to stereo unbalanced audio, digital audio AES/EBU and audio embedded in HDMI. It supports the full range of video resolution formats and frame rates, with progressive to progressive, interlaced to interlaced and interlaced to progressive downscaling available on each output. 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 SDI2HDMI features a lockable connector on the power supply to prevent accidental disconnection. The compact device may be placed on a tabletop or wall mounted.
