ACO6800+ISD
Intelligent Single Switchover for SD/HD/ASI Sources
The ACO6800+ switchover module is designed for the 6800+™ core processing platform and provides both the primary and backup paths critical to maintaining uninterrupted video and audio signal flow. Multiple versions of the ACO6800+ are offered to suit the varied redundancy needs of broadcast and production facilities, OB trucks, satellite operators, cable headends, and mobile TV and IPTV operations.
The ACO6800+ is available as a single- or dual-channel module that provides switchover capabilities from the primary to the backup path in the event of a signal failure. In addition to the basic switchover module, the ACO6800+ is also available as an intelligent Q-SEE™-compliant module that monitors video, audio and metadata at ingest, checks levels for consistency and scans for errors.
Features
ACO6800+ISD
Intelligent single switchover for SD/HD/ASI sources
- Monitor Input 1 (primary) for loss of signal and failover to Input 2 (secondary)
- Single-channel module only
- Switchback to primary happens when the primary signal has been restored for a predetermined period of time
- Input relay bypass on the back module (to ensure signal path in the event of power loss to the frame)
- Remote control and status via GPI/GPO
- GPI control (Switch Input 1 online, Switch Input 2 online, Relay Bypass)
- GPO status (Input 1 online, Input 2 online, Relay Bypass active)
- GPI can be user-configured for momentary/latched and high/low operation
- GPO status can be user-configured (high/low, momentary/latched) to indicate status
- Configuration, control and status via CCS Navigator
- Toggle switch on front of module to force switch between primary (up position) and secondary (down position) inputs
- Apply Q-SEE alarm monitoring to each of two inputs (SD+8 AES embedded or HD+8 AES embedded). ACO is user-configured to operate in either SD or HD format. There is no automatic input format detection. Both inputs are actively monitored. By default, all alarms will be disabled.
- Generate a Q-SEE thumbnail for one of the two inputs
- Online only — up to two frames per second with audio meter for one of eight embedded AES signals
- Online and offline — up to one frame per second, each with audio meter for one of eight embedded AES signals (the same one for each thumbnail)
- Thumbnails are generated as they are selected in the user interface
ACO6800+ASID
Intelligent single switchover for ASI sources
- Monitors both inputs for loss of signal and ETR 290 priority 1 and 2 alarms and switch from Input 1 (primary) to Input 2 (secondary) on detected failure
- Single-channel module only
- Three modes of operation Automatic, Manual or Non-resetting. Automatic Switchback to primary happens when the primary signal has been restored for a predetermined period of time. Manual allows user selection of switch control. Non resetting when the module detects a failure on input 1 and switches over to input 2; output will stay switched to output 2 until the user manually switches the control back to input 1.
- Input relay bypass on the back module (to ensure signal path in the event of power loss to the frame)
- Remote control and status via GPI/GPO
- GPI control (Switch Input 1 online, Switch Input 2 online, Relay Bypass)
- GPO status (Input 1 online, Input 2 online, Relay Bypass active)
- GPI can be user-configured for high/low operation
- GPO status can be user-configured (high/low) to indicate status
- Configuration, control and status via CCS Navigator
- Apply Q-SEE alarm monitoring to each of two inputs. There is automatic input format detection. Both inputs are actively monitored. By default, all alarms will be disabled except loss of signal.
ACO6800+DSD
Basic dual switchover for SD/HD/ASI sources
- Monitor Input 1 (primary) for loss of signal and failover to Input 2 (secondary)
- Switchback to primary happens when the primary signal has been restored for a predetermined period of time
- Input relay bypass on the back module (to ensure signal path in the event of power loss to the frame).
- Remote control and status via GPI/GPO
- GPI control (Switch Input 1 online, Switch Input 2 online, Relay Bypass)
- GPO status (Input 1 online, Input 2 online, Relay Bypass active)
- GPI can be user-configured for momentary/latched and high/low operation
- GPO status can be user-configured (high/low, momentary/latched) to indicate status
- Configuration, control and status via CCS Navigator
- Toggle switch on front of module to force switch between primary (up position) and secondary (down position) inputs
ACO6800+IDSD
Intelligent dual switchover for SD/HD/ASI sources
In addition to the same features as the ACO6800+DSD, this version allows you to:
- Apply the Q-SEE alarm monitoring to each of two inputs (SD+8 AES embedded or HD+8 AES embedded). ACO is user-configured to operate in either SD or HD format. There is no automatic input format detection. Both inputs are actively monitored. By default, all alarms will be disabled.
- Generate a Q-SEE thumbnail for one of the two inputs:
- Online only — up to two frames per second with audio meter for one of eight embedded AES signals
- Online and offline — up to one frame per second, each with audio meter for one of eight embedded AES signals (the same one for each thumbnail)
- Thumbnails are generated as they are selected in the user interface
ACO6800+ISCST
Intelligent single Clean/Quiet switchover for SD/HD/ASI sources
In addition to the same features as the ACO6800+ISD, this version offers:
- Single-channel capability
- Daughtercard with SD/HD frame sync and eight AES synchronizer
- Frame reference input to drive frame sync
- Clean/Quiet switch between selected sources
ACO6800+4X2D
Intelligent Single ACO with 4X2 Mode
In addition to the features of the +ISD, this version offers:
- Single ACO with 4 inputs
- Independent Q-SEE alarm sets for all 4 inputs
- Input A1 and A2 follow ACO series standard switch mechanism, including alarm-based auto switching, manual switching and GPI switching
- Input B1 and B2 serve as emergency backup inputs, have higher priority over input A1/A2, can be manually selected as primary input source through GPI or CCS Navigator/web browser parameter control
- Two independent output groups: Out-A and Out-B. Out-B can be configured as the same as Out-A, or any input channel.
- Adjustable frozen detection sensitivity
Product Details
The Intelligent ASI ACO6800+ASID module monitors ASI transport stream inputs for ETR 290 priority 1 and 2 alarms. Each alarm has user settings for threshold, switch-back time and alarm detection levels.
These intelligent ACO modules allow for the setting of customizable parameters for each level being monitored and perform an automatic switchover when any level changes or disruptions are detected.
The Clean/Quiet ACO6800+ISCST module ensures that there are no abrupt relays or interruptions of video and audio signals (e.g., in the event of a cable or fiber cut) and no audible “pops” or noises when the automatic changeover takes place, restoring the integrity of the signal.
