4K2HD

AJA’s 4K2HD down-converts professional SDI 4K/UltraHD signals to HD resolution using AJA’s high quality scaling for cost effective monitoring and conversion. 4K2HD’s HD-SDI and HDMI outputs are both live all the time, producing fantastic looking HD images for on-set monitoring or direct-to-air broadcast. The 4K2HD supports automatic or configurable HDR metadata generation for the SDI output VPID and HDMI output HDR infoframe. 4K2HD supports high frame rate (HFR) 4K inputs at 50 and 60fps and gets converted to HD outputs at 50 and 60fps for accurate viewing. 4K2HD’s configuration options can extract an HD resolution image from the 4K input to provide a one-to-one pixel image for 4K focus checks on HD displays. Configuration can be set remotely via AJA Mini-Config software control over USB.
