1. OVERVIEW
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 or AES
inputs can be packaged with the video to create an A to D frame synchronizer with audio embedder. In
addition, Evertz fault monitoring processor will analyze and report video and audio problems via an On-
Screen-Display, or remotely via VistaLINK®SNMP.
The Features of the A to D Process are:
 10 bit, 54MHz 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 3 components, gain control
on all 3 components, inter-channel delay control in 18 ns increments.
 Sync on green or separate sync input.
 300mV or 4V separate sync support.
The Features of all 7730ADC’s are:
 Three input BNCs for Y, Pb, Pr or G, B, R input.
 One sync input BNC for separate sync.
 Two SDI 525 or 625, 270 Mb/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). 75 Ohm 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 bar graph level Indicators.
 Decodes vertical interval time code (VITC) or longitudinal time code (LTC) and “burns” the time code
into the picture.
 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.

Grey background indicate un-implemented or un-tested features
The Features of "-A4" option are:
 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 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.
 75 Ohm coaxial (unbalanced) DARS reference input on BNC.
 Loss of video modes: pass audio, mute audio
The Features of "-AES" option are:
 75 Ohm coaxial (unbalanced) AES inputs (2) on BNC.
 Audio delay equivalent to 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 (2 channels of audio) is multiplexed on the outgoing digital video.
 2 unbalanced AES audio outputs delayed equivalently to the embedded audio.
 75-Ohm coaxial (unbalanced) DARS reference input on BNC.
 Loss of video modes: pass audio, mute audio.
 Bypass relay protection that allows removing the card without re-wiring AES audio.
1.1. FUNCTIONAL DESCRIPTION
Component analog video is converted to 10 bit parallel data. Inter-channel delay control allows the time-
alignment of the 3 components with 18ns resolution. The over sampled components are then decimated
and colour space converted (if G, B, R format) into Y, Cb, Cr in 4:4:4 format. The Cb and Cr are then
further decimated to create 4:2:2. Gain, black level, and setup removal video processing functions are
performed during the A to D process while colour space conversion is done in the digital world.
In the 7730ADC-A4 version, the audio is converted from balanced analog to digital PCM audio. The
7730ADC-AES, receives the input AES audio and rate converts it to synchronous 48kHz. The digital audio
is then delayed to match the delay experienced by the video in the video synchronizer (with +S option).
This delayed audio (with +S option) is formatted properly and delivered to the user as unbalanced 75 Ohm
AES audio on BNC. It is also formatted into one group of audio and embedded on the SDI output video.
The audio is also processed to extract level and phase information. The CPU creates the level and phase
bar graphs and writes them out to the On Screen display (OSD) memory.
The hardware mixes (keys) the on screen text and bar graphs display information onto the video stream.
This video goes out through a high quality composite encoder with the OSD "burn-ins".
The CPU also gets pushbutton and toggle switch commands from the card edge controls and draws
extensive menus for configuring the operation of the card.
The following block diagrams illustrate the processing blocks.
