IQMCC30 3G/HD/SD Motion Compensated Frame Rate Converter

The IQMCC30 provides multirate frame rate and format conversion for 3 Gb/s SDI, and HD-SDI digital video signals. Using high-quality motion compensated image processing the IQMCC30  from Grass Valley delivers high-quality conversion in a compact and affordable modular form factor ideal for broadcasters, news agencies, and content providers needing to deliver premium content to domestic and international audiences. 

IQMCC30 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...

FEATURES

  • Motion compensated SD/HD/3G frame rate conversion
  • High-quality up/down/crossconversion, including conversion aperture control and clean cut mode
  • Frame synchronizer with HD tri-sync/SD bi-level reference input and input loss detection, and filmic field detection optimizes 3:2, 2:2 picture cadences
  • Aspect ratio conversion including preset ARC maps relative to conversion modes, 32 ARC user memories, pan, tilt, size, and output crop adjustments
  • Aspect ratio control (signaling reading and writing) using ETSI WSS and AFD Video Index signaling (RP186, SMPTE ST 2016)
  • Video processing features include: gain, offset, luma clipper, horizontal and vertical picture enhancement, and adjustable RGB gamut legalization
  • Metadata support — Closed caption passing or processing for CEA608/708 and OP42/OP47/SMPTE ST 2031 WST captions, and VITC or SMPTE ST 12 timecode translation with output line adjustment (VITC)
  • Additional processing options, including noise reduction (adaptive spatial and recursive)
