IQUDC40 12G/3G/HD/SD 4K UHD Up/Down/Cross Converter

The IQUDC40 is a flexible 4K UHD processing unit able to process and translate both quadrant (square division) and 2SI (2 sample interleave) quad-link formats as well as 12G-SDI single-link signals. Converting to or from 4K UHD to HD/SD allows re-purposing of existing assets, and all common video and audio processing tasks are also covered.

IQUDC40 includes a frame synchronizer, capable of referencing to a SD bi-level or HD tri-level reference and a variable aspect ratio converter with reading and writing of WSS, VI and 2016 AFD signaling (not available in 4K UHD to 4K UHD mode). Video processing includes powerful picture enhancement tools, including edge enhance, High Dynamic Range...

FEATURES

  • High-quality up/down/crossconversion for SDI video inputs including conversion aperture control and cadence insertion, detection and removal (e.g., 1080i/59 3:2 to 4K23)
  • Linear motion adaptive frame rate conversion for all supported standards and applications requiring up- or downconverting to or from 4K UHD material, or for converting between HD/SD formats (not available in 4K UHD to 4K UHD mode)
  • 4K UHD interfacing to translate between 2SI and square division workflows for maximum signal compatibility
  • Frame synchronizer with HD tri-sync/SD bi-level reference input, up to 8 frames of video delay and input loss detection with default output of black/pattern
  • Aspect ratio conversion including preset ARC maps relative to conversion modes, pan, tilt and size adjustments
  • Aspect ratio control (signaling reading and writing) using ETSI WSS and AFD Video Index signaling (RP186, SMPTE ST 2016)
  • Video proc features include: gain, offset, hue, horizontal and vertical picture enhancement, color corrector and RGB gamut legalization
  • Wide color gamut support with BT709 and BT2020 color space conversion including manual and automatic operation
