End to end monitoring with Tag Video Systems
Correlate QoS and QoE metrics across your entire workflow from source to screen.
How it works in 3 steps
From source to screen: one unified view
TAG’s Realtime Media Platform provides deep visibility into every stage of content transport, while Witbe’s Virtual NOC validates playback on real devices.
- TAG confirms that content is correctly ingested, packaged, and distributed.
- Witbe measures startup time, buffering, and visual quality exactly as viewers experience it.
- Together, they eliminate blind spots between headend and screen.
Now, your operations team sees the full path, and every issue in one view.
Proactive issue detection across the entire workflow
When a quality issue appears, operators can instantly see where it starts and how it affects viewers before the audience ever notices.
The integrated system detects and correlates problems across the entire workflow, including:
- Packet loss or network congestion that affects delivery quality
- DRM or CDN misconfigurations impacting availability or performance
- Device-specific playback errors such as buffering or app crashes
- Latency differences between broadcast and OTT platforms
When an anomaly is detected, TAG’s dynamic penalty box automatically focuses the monitoring view on the affected channel, while Witbe confirms real-world playback on actual devices.
This ensures operators can immediately validate the issue, confirm the fix, and prevent further impact.
Benefit: faster root-cause detection, fewer escalations, and shorter MTTR.
Real device testing for true QoE insights
Network data can confirm that a stream was delivered but not how it actually played.
By testing on real consumer devices, Witbe detects the subtle yet impactful issues that are invisible to network monitoring, such as:
- Buffering and playback interruptions
- Audio-video sync delays
- Macroblocking or visual compression artifacts
- Resolution drops under fluctuating bandwidth
- App or player behavior that impacts performance
These real-world measurements bridge the gap between network success and viewer satisfaction, ensuring your service delivers the intended experience on every device, in every environment.
Centralized analytics and reporting
All monitoring results are automatically consolidated in Smartgate, giving operations teams a single source of truth for both network and device-level data.
The combined view merges TAG’s transport KPIs: bitrate stability, packet error rates, stream latency; with Witbe’s QoE metrics, including start-up time, buffering ratio, and video resolution stability.
This full correlation provides a complete picture of performance.
In Smartgate, teams can filter reports by channel, device type, market, or time period to spot recurring issues, track improvements, and optimize operational workflows over time.
Scalable for global operations
The joint solution scales effortlessly for large, multi-region deployments.
TAG’s transport monitoring can be deployed at multiple points across the delivery network, while Witbe’s global infrastructure of datacenters and field devices validates QoE in every target market.
This global reach ensures consistent, end-to-end visibility; whether you’re managing live events, regional feeds, or global OTT services.
Ideal for broadcasters, streaming platforms, and operators handling large content portfolios across diverse geographies.
Proven in action: Superbowl 2025 case study
During one of the most watched live events of the year, TAG and Witbe deployed their joint monitoring solution across multiple providers and platforms, from major OTT services to traditional cable.
The combined system delivered unprecedented visibility into how each platform performed under real-world pressure:
- Latency comparisons between OTT platforms and broadcast, measuring delay from source to viewer screen
- Content integrity verification using TAG’s content matching to ensure the correct feed was delivered without alteration
- Playback performance under peak traffic, capturing startup times, buffering events, and audio-video quality on real devices
- Real-time anomaly detection, enabling immediate response to unexpected behavior
The findings were compiled into a detailed post-event performance report, providing actionable insights that broadcasters and OTT providers can use to improve the reliability and quality of future large-scale live streaming events.
Key advantages
-
Unified expertise
Stop stitching together data from separate systems. TAG and Witbe integrate seamlessly, giving operations teams one coherent view in Smartgate, one mutliviewer and one penalty box instead of multiple dashboards.
-
Operate with confidence at scale
Monitor hundreds of channels and services across regions and platforms, ensuring consistent performance and verified quality worldwide.
-
Detect and resolve issues faster
Engineering, NOC, and field teams work from the same source of truth to correlate alerts automatically, pinpoint root causes instantly, and validate fixes on real devices.
Unify your monitoring, simplify your operations
Frequently asked questions
-
What does end-to-end video monitoring mean?
End-to-end monitoring connects network-level QoS (Quality of Service) with device-level QoE (Quality of Experience). It covers every stage, from content encoding and transport to playback on real consumer devices, ensuring complete visibility from source to screen.
-
Why is combining QoS and QoE monitoring important?
QoS metrics alone show that a stream was delivered, not how it played. QoE testing exposes viewer-impacting issues like buffering, sync delays, or app errors that network logs cannot detect. Combining both allows operators to pinpoint exactly where and why problems occur.
-
How do you measure latency from source to screen?
TAG’s Content Matching technology identifies identical frames across different streams, while Witbe measures playback timestamps on real devices. This combination calculates precise delay between broadcast and OTT or between CDN nodes and the viewer screen.
-
What kind of issues can this solution detect?
It detects everything from packet loss and network congestion to CDN slowdowns, encoding or DRM errors, and playback issues such as buffering or resolution drops on real devices.
-
Can it scale for multiple regions and platforms?
Yes. TAG can monitor streams at multiple points across your delivery network, while Witbe enables QoE testing on real devices hosted in your own locations or in Witbe datacenters. This flexibility allows operations teams to validate playback quality in every target market and maintain consistent visibility worldwide.
-
What are the main benefits for operations teams?
One dashboard for all metrics, eliminating tool fragmentation.
- Faster root-cause detection and confirmation of fixes
- Reduced downtime and fewer escalations
- Consistent reporting for SLA validation and cross-team collaboration
-
How are results visualized?
All metrics are available in Smartgate, Witbe’s observability platform. Operators can correlate TAG’s transport KPIs with Witbe’s QoE results, visualize root causes, and generate reports filtered by device, channel, or region.
