IQUDC30 3G/HD/SD Up/Down Converter

Using high-quality motion adaptive de-interlacing and flexible scaling technology, the IQUDC30 is a broadcast-quality conversion module able to handle a wide variety of common applications such as upconversion for SD content repurposing on HD channels, or downconversion to maintain SD output feeds.

The IQUDC30 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. Audio handling includes audio channel routing, delay adjustment and level controls. Video metadata such as timecode, SMPTE ST 2020 Dolby, closed captions and teletext captions can...

FEATURES

  • High-quality up/down/crossconversion for SDI video inputs including conversion aperture control
  • Frame synchronizer with HD tri-sync/SD bi-level reference input and input loss detection
  • Aspect ratio conversion including preset ARC maps relative to conversion modes, selectable border color and pan, tilt, size, and input crop adjustments

  • Video processing features include: gain, offset, hue, horizontal and vertical picture enhancement, and RGB gamut legalization
  • Metadata support — Closed caption passing or processing for CEA608/708 and OP42/OP47/WST captions, VITC or SMPTE ST 12 timecode translation, and ancillary data bridge for 7 blocks of ANC data passing
  • Built-in test pattern generator and 19 character scrolling caption generator
  • Additional processing options including noise reduction (adaptive spatial and recursive) and linear frame rate conversion
