You Stream It – We Measure It
All types of video streams covered.
Ideal for ISPs, MSOs, OTTs, Content Providers.
Your Complete QoS and QoE Solution
Real customer experience data and analytics
For Telcos, Streaming Providers, Integrators and Regulators we:
- automate E2E measurements of video streaming services, web and network performance
- provide user-centric quality diagnosis from the real end devices
- calculate end-user Quality of Experience (QoE) based on the latest standards and research
- optimize your services and identify QoE and QoS network bottlenecks
Gain insight into video streaming QoE and more!
The Surfmeter app now enables us, for the first time, to record qualitative measurements that are comparable with the customer’s actual perception.

Know how your users perceive video and network quality
Calculate customer experience
Users typically blame their provider for video quality issues. However, the relationship between bandwidth and video quality is not linear.
- Gather video and streaming QoS data and calculate QoE
- Pinpoint the parameters degrading customer satisfaction.
- The MOS – Mean Opinion Score – predicts how a customer would rate a video.
- Trust a validated model – relying on real customers at a world-leading telco.
A single quality score to express CX

What we measure, or Key Performance Indicators and Key Quality Indicators
While it’s long, this list is not exhaustive. See below for a link to our full documentation!
Video Streaming Metrics
- ⏳ Initial Loading Delay
What it is: Time until playback starts.
Why it’s important: A key indicator of how quickly users can start watching. Long delays lead to abandonment. - ⚡ Video Response Time (Time to First Byte)
What it is: Time from request to receiving the first byte of video data.
Why it’s important: Reflects connection quality to the CDN or video server. - 🛑 Stalling Ratio
What it is: Percentage of time video playback is stalled.
Why it’s important: One of the most visible disruptions to QoE – ideally, this should be 0%. - 🎢 Number of Quality Switches
What it is: Count of resolution changes during playback.
Why it’s important: High fluctuation may signal unstable connections or poor adaptation behavior. - 📊 Initial vs. Longest Played Resolution
What it is: Difference between the starting resolution and the resolution played the longest.
Why it’s important: Shows if the experience starts at low quality and improves – or stays poor. - 🌐 Content Server IP / Hostname
What it is: Source of the video stream.
Why it’s important: Useful for identifying CDN or peering issues. - ⭐ Overall Mean Opinion Score (MOS)
What it is: Calculated user-perceived quality (1–5).
Why it’s important: A standardized summary score combining video loading, stalling, and visual quality. - 📉 Stalling Quality Contribution
What it is: Impact of stalling events on overall MOS.
Why it’s important: Helps pinpoint if stalling is the main reason for poor experience. - ✨ Audiovisual Quality Contribution
What it is: Impact of resolution, bitrate, and codec on the MOS.
Why it’s important: Shows how audio and video are contributing to overall quality. - ⏱️ Latency
What it is: Latency between the video being available at the CDN vs receiving at the client.
Why it’s important: Gives an indication of live streaming latency.
Web & Network Metrics
- 🚦 Time to First Byte (TTFB)
What it is: Measures how quickly the browser receives the first byte from the server.
Why it’s important: Indicates backend/server responsiveness – long delays suggest infrastructure or CDN issues. - 🏁 First Contentful Paint (FCP)
What it is: Tracks when the first visible element finishes loading.
Why it’s important: Reflects how fast the user sees the main content – a core perception metric for speed. - ⌛ Total Load Time
What it is: Time until the page is fully loaded and all resources are in place.
Why it’s important: Important for user satisfaction and full page interactivity, especially on slower networks. - 🔄 Speed Index
What it is: Evaluates how quickly visual content is displayed during load.
Why it’s important: Gives a holistic view of perceived performance from a user perspective. - 👆 First Input Delay (FID)
What it is: Measures time between user interaction and browser response.
Why it’s important: Captures interactivity – long delays frustrate users and break engagement. - 📥 Download Speed
What it is: Rate at which data is received from the internet.
Why it’s important: Determines how fast users can stream, browse, or download – critical for user satisfaction. - 📤 Upload Speed
What it is: Rate at which data is sent to the internet.
Why it’s important: Important for video conferencing, file sharing, and cloud-based applications. - 🧭 DNS Load Time
What it is: Time taken to resolve a domain name to an IP address.
Why it’s important: Impacts the initial load time of websites or services – slower DNS = slower start. - 📦 Network PCAP
What it is: A full packet capture of network traffic.
Why it’s important: Enables deep diagnostics and troubleshooting for packet-level issues. - 🖥️ Screen Recordings
What it is: Visual recordings of user sessions.
Why it’s important: Helps correlate technical performance with actual user experience.
