Audio Video Sync & Quality Monitor

Monitoring of QoE (Quality of Experience) and QoS (Quality of Service) for audio/video transmissions 


Audio Video Sync & Quality Monitor (AVSQM) is a powerful and scalable solution which enables to measure and monitor both QoE (Quality of Experience) and QoS (Quality of Service) for audio/video transmissions, especially for TV channels broadcasting.


QoE (Quality of Experience) is measured by the following indicators (KPI: Key Performance Indicators):

  • Perceived video quality (MOS value and indicators like blockiness, blur, etc.)
  • Perceived audio quality (MOS value and indicators like bandwidth, HF presence, etc.)
  • Video delay
  • Audio delay
  • Skew (amount of misalignment between audio and video)


QoS (Quality of Service) is measured by the following indicators (KPI):

  • Transmission-related parameters: packets delay, jitter, reordering, corruption, etc.
  • Machine-related parameters: CPU usage, RAM usage, etc.


AVSQM includes three different video quality metrics, dedicated to three different codecs:

  • MPEG-2
  • H.264
  • HEVC


AVSQM enables to:

  • Compare the different versions (supplied by different Internet Service Providers or Telecom Operators) of a TV channel
  • Monitor audio and video broadcast over different networks
  • Benchmark audio and video equipment
  • Check non-regression after audio/video equipment firmware update
  • Receive alerts when problems happen
