7730ADC & 7730ADC-A4

Component Analog Video to SDI Converter

Interact with this product in a Layout Tool:

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

  • A to D process

  • Internal processing to maintain 10-bit digital video quality
  • Y, Pb, Pr or G, B, R input support
  • Black level clamp on all components
  • User-adjustable input video processing functions: black level control on all three components, gain control on all three components, inter-channel delay control in 18ns increments
  • Sync on green or separate sync input
  • 300mV or 4V separate sync support
  • Features of all 7730ADCs are:

  • 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 bar graphs
  • 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 bar graph graphics for monitoring
  • EDH encoding on SDI output
  • One combination input BNC that can either be an LTC input or a composite analog reference input (NTSC or PAL-B)
  • 75Ω or Hi-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 bar graph 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 via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
  • Features of -A4 option are:

  • Four balanced analog audio inputs on two removable barrier strips
  • High impedance inputs (user supplies termination resistors for other impedances)
  • 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 five seconds
  • Audio advance of up to one frame less three microseconds
  • One group (four channels of audio) is multiplexed on the outgoing digital video
  • Two 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
