The 7736CE2 series of modules are broadcast quality component serial digital to composite analog video converters with an extensive list of advanced features. The 7736CE2-A4 and 7736CE2-A8 versions offer respectively four (two per encoding channel) or eight (four per encoding channel) high quality audio digital to analog converters that can be driven from discrete AES inputs or audio embedded within the video input signal. The module features a clean (asynchronous) and a fast (synchronous) input video lock modes to handle upstream switches. In addition, control of card is via an On-Screen-Display or remotely via VistaLINK®.

Features

  • Two component serial digital inputs (525 or 625)
  • One composite analog video output per channel WITHOUT OSD text
  • Internal processing to maintain 10 bit digital video quality
  • 12 bit output video digital to analog conversion
  • One monitoring quality video output with OSD for card configuration
  • User adjustable output video processing functions: black level (brightness), gain (contrast), hue, and saturation
  • User selectable luminance and chrominance filters for different applications (i.e. broadcast vs. studio)
  • User selectable horizontal blanking interval width (narrow or normal)
  • One composite analog reference input (NTSC or PAL-B) on BNC 75Ω or high-Z (jumper configurable) input impedance
  • Video Frame synchronizer (with +S option)
  • Infinitely variable output phase
  • Freeze modes: black, freeze
  • Input video lock mode: clean or fast
  • Adjustable free running frequency. Both channels must be free running to be able to adjust frequency
  • A comprehensive on screen display for module config

Features of "-A4" and the "-A8" Options

  • 7736CE2-A4 (per video channel)

  • One half group (2 channels) of synchronous 20-bit audio may be de-multiplexed from the incoming digital video
  • 1 unbalanced (or balanced) AES audio input (up to 48kHz, 24 bits) on BNC (or terminal strip for balanced audio)
  • 2 high quality 24 bit audio channels are converted to balanced analog on 2 removable barrier strips

  • 7736CE2-A8 (per video channel)

  • 4 high quality 24 bit audio channels are converted to balanced analog on 2 removable barrier strips

  • 7736CE2-A4 and 7736CE2-A8

  • User selects either the de-embedded audio or the input AES audio
  • Audio delay tracks the video delay with the +S option
  • Low impedance outputs (66Ω)
  • Analog audio output levels are adjustable
  • Additional audio delay of up to 2.5 seconds
  • Audio advance of up to 1 frame, depending on video delay
  • Loss of video modes: pass audio, mute audio
