7700ACO2-HD Dual HD/SD-SDI Smart Automatic Changeover
Revision 1.0 Page - 1
1. OVERVIEW
The 7700ACO2-HD is the industry’s leading smart automatic changeover (ACO) for high definition
1.5Gb/s or standard definition 270Mb/s serial digital video signals.
This device provides:
• Dual processing paths on a single module
• Smart HD/SD-SDI automatic protection switching of both paths
• Video and Audio Proc Amp Control
• Built-in Trouble Slide per ACO
• Optional IntelliGain™ Audio Loudness Processing with Dynamic Audio Range Control
• Optional IntelliTrak™ Audio/Video LipSync Analysis
• Optional StreamLINK™ H.264 video encoder for confidence monitoring
• Optional ThumbLINK™ Thumbnail generater for confidence monitoring
These modules have dual independent processing paths providing both high density and availability of
any HD-SDI or SD-SDI video inputs signals (program and back-up). These modules provide a passive
loop-thru of both primary and backup input video sources and provide dual safe program outputs.
The 7700ACO2-HD incorporates Evertz proprietary SoftSwitch™ technology for clean video and
embedded audio switching. Line synchronizers on the video inputs can accommodate differences in
timing of up to ±1/2 a line on the video inputs.
The 7700ACO2-HD incorporates Evertz essential audio and video monitoring which is used to drive the
real time automatic switch logic processor. Common parameters include user configurable loss of signal,
freeze, and black detect.
The 7700ACO2-HD can optionally be ordered with Evertz® patented IntelliGain™ Audio and Loudness
Processor. The IntelliGain™ processor is designed to normalize perceived differences in audio loudness
in real time for any HD/SD-SDI signal with embedded audio. This module will internally de-embed the
audio signals, regulate the signal level based on a used defined target loudness level, then re-embed the
corrected audio signals back into the video output.
The 7700ACO2-HD can optionally be ordered with Evertz® patented IntelliTrak™ Audio/Video LipSync
Analysis. IntelliTrak™ non-invasively (no watermark) detects audio and video latency between two video
signals, in real time with normal content.
As part of a complete signal monitoring chain, the 7700ACO2-HD can optionally be ordered with Evertz®
ThumbLINK (+TL) for or Evertz® StreamLINK (-SLKE) for a H.264 encode of either all four inputs in a
quad-split, or any one input, built off Evertz® award winning StreamLINK engine.
VistaLINK
®
enables control and configuration capabilities via Simple Network Management Protocol
(SNMP). This offers the flexibility to manage the module status monitoring and configuration from SNMP -
enabled control systems such as Evertz VistaLINK
®
PRO locally or remotely.
The 7700ACO2-HD occupies two card slots and can be housed in the 3RU 7800FR frame which has a 15
slot capacity or the portable 3RU 350FR frame which has a 7 slot capacity.
