Convert & Scale HDMI to SDI


The Thinklogical HDMI to SDI Converter allows you to seamlessly convert an HDMI or DVI signal to a broadcast quality SDI signal. The HDMI to SDI Converter is fully SMPTE compliant, and includes a genlock input. User interface options include a front panel LCD and encoder, and remote control via the serial port (RS-232) and Ethernet port.  Audio inputs include HDMI embedded (up to eight channels), digital AES (single stereo pair) and balanced analog (single stereo pair). Audio outputs include SDI embedded (up to 8 channels). The HDMI to SDI Converter also has a fiber output option that is fully compatible with our SDIXtreme 3G+ line of receivers for a comprehensive conversion and extension solution.



  • Per-pixel motion-adaptive video noise reduction – removes the white Gaussian noise present in most types of video

  • Content-adaptive block and mosquito noise reduction – significantly reduces the blocking and mosquito noise artifacts present in compressed video

  • Advanced per-pixel, motion-adaptive, edge-adaptive 3D de-interlacing with support for arbitrary film cadences – removes “jaggies” and “feathering” to produce smooth and clear images

  • Adaptive scaling – produces sharp and clean images at low or high resolutions

  • Natural depth expansion – enhances details and sensation of depth for greater realism and super resolution effect

  • Adaptive contrast enhancement (ACE) – brings out shadow detail without crushing mid-tones or highlights

  • Intelligent color remapping (IRC) – enables vivid color without hue shifts and clipping while maintaining accurate flesh tone

  • Qdeo™ true color – a unique solution for using the full dynamic range of 10-bit and 12-bit displays which eliminates contouring seen when viewing typical 8-bit consumer video
