iControl Audio-Video Fingerprints

Lip Sync Error Detection, Audio/Video Delay Measurement and Content Mismatch Alarm

iControl Audio/Video Fingerprint Analysis allow detection and measurement of lip sync errors as well as alarming on unexpected signal delays and audio/video content mismatches. Audio/Video Fingerprints can be used to complement multichannel playout monitoring, remote signal monitoring and most system configurations supported by iControl.

FEATURES

  • Powerful lip synchronization detection and alarming
  • Real-time computation of fingerprints from multiple signals
  • Powerful lip sync delay analysis
  • Detection of up to ± 4s of delay
  • Delay measurement with a ± 2 ms accuracy
  • Versatile content comparison and mismatch alarming
  • Video content mismatch based on motion
  • Audio content mismatch based on audio levels
  • Allows users to define the area of the video frame that will contribute to video fingerprints, providing maximum flexibility in defining content comparison settings
  • Mismatch is detected in a matter of seconds, allowing operators to quickly respond to unexpected conditions

Multisignal, Multisite and Multiformat Monitoring

  • Collects fingerprints from multiple Densité modules, including:
    • ADX-3981: 3G/HD/SD 8 AES audio and metadata de-embedder
    • AMX-3981: 3G/HD/SD 8 AES audio and metadata embedder
    • EAP-3901: 3G/HD/SD embedded audio processor
    • EAP-3101: SD embedded audio processor
    • HCO-1822: 2x1 HD/SD/ASI change-over
    • HLP-1801: HD/SD lip sync probe
    • XVP-3901: 3G/HD/SD up/down/crossconverter with audio processor
  • Supports lip sync monitoring across multiple key signal formats
  • Multisite support: fingerprints can be collected from multiple locations, and can be compared centrally or across multiple sites
  • Signal groups can be defined for more effective monitoring across complex networks

Accurate Measurement and Extensive Alarm Management

  • User-selectable alarm thresholds
  • Provides accurate lip sync error measurement in milliseconds
  • Alarms and measurements can be forwarded to Kaleido multiviewers
  • All alarms can be captured by the powerful iControl log viewer
  • Detected alarms can also be configured with the iControl alarm management, for email notification, SNMP alarming and other automatic action triggers
