Product Manual
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
- The 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
- 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 components, gain control on all components, inter-channel delay and picture position control in 13.5ns increments
- Sync on green or separate sync input
- The Features of all 7730ADC-HDs are:
- Three input BNCs for Y, Pb, Pr or G, B, R input
- One sync input BNC for separate sync
- Two HD SDI 74.25 or 74.176MB/s component digital video output without OSD text or audio bar graphs
- One combination output that can either be an extra HD SDI output or composite analog video output
- When configured as a composite analog output it will be a clean output (no picture) and have the OSD text and bar graph graphics for monitoring
- 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 via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
- The 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 of up to five seconds
- One group (four channels of audio) is multiplexed on the outgoing digital video
- Two unbalanced AES audio outputs delayed equivalently to the embedded audiodelay
- 75Ω coaxial (unbalanced) DARS reference input on BNC
- Loss of video modes: pass audio, mute audio
