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
