7730ADC & 7730ADC-A4

SDI Component A to D Converter

VistaLINK® enabled

The 7730ADC line of component analog video to serial digital converters are broadcast quality A to Ds with an extensive list of additional features. High quality analog to digital conversion of audio inputs can be packaged with the video to create a A to D frame synchronizer with audio embedder. In addition, Evertz fault monitoring processing will analyze and report video and audio problems via an On-Screen-Display, or remotely via VistaLINK® SNMP.

The 7730ADC (1 slot module) and 7730ADC-A4 (2 slot module) can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.

Features

  • Features of the A to D Process
  • 10 bit, 54MHz sampling of input video
  • Internal processing to maintain 10 bit digital video quality
  • YPbPr or RGB input support
  • Black level clamp on all components
  • User adjustable input video processing functions: black level control on all 3 components, gain control on all 3 components, inter-channel delay control in 18ns increments
  • Sync on green or separate sync input
  • 300mV or 4V separate sync support
  • Standard Features
  • Three input BNCs for YPbPr or RGB input
  • One sync input BNC for separate sync
  • Two SDI 525 or 625, 270Mb/s component digital video output WITHOUT OSD text or audio bargraphs
  • One combination output that can either be an extra SDI output or composite analog video output. When configured as a composite analog output it can either be a clean output (no OSD), or have the OSD text and bargraph graphics for monitoring
  • EDH encoding on SDI output
  • One BNC composite analog reference input (NTSC or PAL-B). 75Ω or high-Z, jumper configurable input impedance
  • One frame video synchronizer (with +S option)
  • Infinitely variable output phase (27MHz clock increments)
  • Freeze modes: black, freeze, pass
  • Menu adjustable free running frequency
  • VU/PPM bargraph level Indicators
  • Decodes vertical interval time code (VITC) and "burns" the time code into the OSD Monitoring output
  • A comprehensive on screen display is available to configure the various features of the module
    • Flexible configuration of the text and audio bar graph information displays
    • An extensive list of error conditions can be monitored and fault conditions can be configured from these conditions
    • On screen messages can be triggered by the configured fault conditions
    • Fault conditions are reported via VistaLINK® SNMP
    • VistaLINK® capable for remote monitoring and control via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7700FC VistaLINK® Frame Controller
    • -A4 Option Features
    • 4 balanced analog audio inputs on 2 removable barrier strips
    • High impedance inputs (user supplies termination resistors for other impedance's)
    • Analog audio input levels are adjustable. Jumpers set coarse input levels, fine input levels are set by software control
    • Audio delay equivalent video delay (with +S option)
    • Additional audio delay of up to 5 seconds
    • Audio advance of up to 1 frame less 3 microseconds
    • One group (4 channels of audio) is multiplexed on the outgoing digital video
    • 2 unbalanced AES audio outputs delayed equivalently to the video delay
    • 75Ω coaxial (unbalanced) DARS reference input on BNC
    • Loss of video modes: pass audio, mute audio
