IQSYN11 3G/HD/SD Frame Sync

The IQSYN11 provides frame synchronization for HD-SDI at 3 Gb/s or 1.5 Gb/s, or SD-SDI 270 Mb/s. Includes dual-channel independent SDI input processing functionality and agile synchronization. A video proc amp provides complete control over the video levels. The IQSYN11 is a space-efficient low-cost solution that includes core functionality.

FEATURES

  • Dual-channel 3G/HD/SD-SDI synchronizer providing two independent video processing paths on one card with up to three frames of video delay per channel
  • Standards supported:
    • 3G-SDI to SMPTE ST 424/425 level A & B compatible
    • HD-SDI to SMPTE ST 292/274/296
    • SD-SDI to SMPTE ST 259-C
  • Loop-though reference capable of detecting and referencing to a bi-level or tri-level signal and selection from either external input directly or from internal IQH3B chassis reference bus
  • Select either external input reference directly or from internal IQH3B chassis reference bus
  • Precision genlock adjustment allowing you to time any SDI signal accurately
  • Agile, router switching tolerant synchronizer operation
  • Able to pass all ancillary data with independent HANC and VANC blanking control
  • Input loss detection — default output of black/pattern/freeze
  • Edit function for static/animated caption overlay on video output
  • Can be used as a video delay, up to three frames per channel
  • Video proc amp controls including video gain, offset and hue, including Y/C picture position adjustment
  • Built-in test pattern generator and audio tone generator
