7730ADC-HD & 7730ADC-A4-HD

HD Component Analog Video to HD SDI Converter

VistaLINK® enabled

The 7730ADC-HD line of component analog video to serial digital converters are broadcast quality high definition A to Ds with an extensive list of additional features. High quality analog to digital conversion of audio or AES inputs can be packaged with the video to create an A to D 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.

Features

  • Features of the A to D Process
  • 10 bit, 74.25MHz(/1.001) 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 components, gain control on all components, inter-channel delay and picture position control in 13.5ns increments
  • Sync on green or separate sync output
  • Standard Features
  • Three BNCs for YPbPr or RGB input
  • One sync input BNC for separate sync
  • Two HD SDI 74.25 or 74.176Mb/s component digital video outputs WITHOUT OSD text or audio bargraphs
  • One combination output that can either be an extra HD SDI output or composite analog output. When configured as a composite analog output it will be a clean output (no picture), and have the OSD text and bargraph graphics for monitoring
  • One BNC analog reference input (Tri-level sync, NTSC or PAL-B with same frame rate as input video); 75Ω or High-Z jumper configurable input impedance
  • One line video synchronizer
  • Variable output phase (in clock increments)
  • Loss of video modes: black, pass
  • A comprehensive on screen display is available to configure the various features of the module
    • VistaLINK® capable for remote monitoring, control and configuration capabilities via SNMP; using VistaLINK® PRO, CP-2116E or CP-2232E Control Panels. VistaLINK® is available when modules are used with the 3RU 7800FR frame and a 7700FC VistaLINK® Frame Controller module in slot 1 of the frame
    • -A4 Version
    • 4 balanced analog audio inputs on 2 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 inputs levels are set by software control
    • Audio delay of up to 5 seconds
    • One group (4 channels of audio) is multiplexed on the outgoing digital video
    • 2 unbalanced AES audio outputs delayed equivalently to the embedded audio delay
    • 75Ω coaxial (unbalanced) DARS reference input on BNC
    • Loss of video modes: pass audio, mute audio
