V-Factor®, Symmetricom’s QoE Platform, is a robust video quality monitoring solution enabling carriers, Internet service providers and cable MSOs to understand their actual video service quality, in real-time, as experienced by end-users. Through perceptual video quality management, V-Factor is proven to accurately pinpoint end-user video quality thereby simplifying management and accelerating growth of critical IP-based video services.
V-Factor is designed to deliver accurate assessments of end-user quality. Unlike network-based service assurance solutions that monitor network data and attempt to predict end-user experience, V-Factor looks deep into the actual video content. Combining content impairment data with network information, and filtering the results though a sophisticated human vision system (HVS) model, this solution provides a simple, yet accurate video quality MOS (mean opinion score).
V-Factor: Understand your Video Quality
- Understand the service: V-Factor tells you if there is an issue and whether or not it matters to end-users
- Understand the problem: V-Factor reports exactly what the end-users see (blockiness, blur, freeze frame, etc) and pinpoints exact cause.
- Understand the solution: With its fine-grained metrics, V-Factor enables operators to determine impairment source readily and without guesswork.
Solution Benefits:
Accuracy and flexibility in quality monitoring are essential to effectively manage and grow an Internet video business. Key benefits of deploying V-Factor in the network include:
- Accelerated deployments, increased growth
- Lower support costs - shorter time to fix, fewer truck rolls
- Eliminate customer calls through early problem identification
- Increased customer satisfaction, reduced churn, new SLAs
- Differentiated service offering, powerful service marketing
V-Factor QoE Platform Components:
V-Factor consists of the following parts:
- Headend Analyzers: These high performance analyzers examine, in real time, the quality & integrity of source video and detect transcoding and encoding impairments. No and full reference modes ensure most flexible deployment at highest possible accuracy and effectiveness.
- Network Probes: Hardware probes collect and report network performance metrics and content metrics and correlate all metrics directly to achieve perceptual video quality assessments.
- Software Agents: Embedded in set-top-box, PC media players and other platforms, these lightweight components enable real time video monitoring from within the customer premise.
- Management Software: This management software solution aggregates quality information from across the network to provide end-to-end correlation, status monitoring, and problem reporting (via a built-in, web-based GUI or simple integration into an existing OSS).
- V-Factor Score: V-Factor reports simple mean opinion scores (MOS) that provide a clear view of end-user quality. These clear and quantifiable metrics make it easy for operators to understand actual end-user experience.

V-Factor Highlights
- Perceptual Video Quality:
Understand what your customers see with Symmetricom’s unique approach for video quality Monitoring
- Accurate QoE Assessments:
Get a true picture of your video service quality – one you can finally trust
- Comprehensive
End-to-End Solution:
Monitor the entire network with a single, scalable solution
- Highly Adaptable Platform:
Flexible to meet wide range of network applications and requirements
- Monitoring in an Encrypted Network:
A significant challenge with end-end QoE monitoring is determining what is happening within the IP network itself—where content is generally encrypted. V-Factor does deep content analysis on unencrypted streams at network ingress, and correlating this information with IP header analysis performed in the encrypted part of the IP network, determines how network impairments impact actual video content.
