Sentry
High-volume content QoE monitoring
Video Quality Monitoring & Analytics by Telestream iQ
Sentry
A superior Brand is defined in terms of the quality of the content delivered whether it be streamed or broadcast.
Sentry is a software-based quality monitoring solution deployed worldwide by Cable, Broadcast, and OTT Streaming service providers in a range of operational, engineering, and business environments. Years of experience has honed the technology to deliver accurate, repeatable, and reliable measurements to instill confidence that the viewer is experiencing only the highest level of quality.
New and unique to Telestream, the non-reference PVQ measurement can help you quickly identify content that fails to meet your threshold for acceptable video quality.
Detect & Alert on Critical Customer Impacting Issues
Sentry measures and reports on the issues that affects customers the most. The single QoE score, produced by proprietary Telestream algorithms, is a true reflection of the customer experience. It is only confidence in the quality of delivery that reduces churn while increasing operational efficiencies.
Highlights
- Ensures regulatory compliance with comprehensive audio loudness and caption monitoring
- Reacts before the customer reacts to avoid costly viewer dissatisfaction
- QoE scoring correlates directly to the quality of the viewing experience
- Actionable alerts with reason codes facilitate fast troubleshooting
Easily Scale as your Network Evolves
Whether monitoring one channel or over a thousand, Sentry monitoring capability can expand to match capacity and geographic footprint growth, and the evolution of functionality requirements. Sentry’s software-based solution protects investment and future-proofs the monitoring system as standards and technologies change.
Highlights
- Future-proof your monitoring network to encompass new technologies and services
- Easily configure measurements and alerts for every service at every point in the workflow
- Scalable monitoring of a few services to over a thousand
Picture Quality Assessment
The TekMOS measurement—unique to Telestream—is a picture quality scoring system that makes it easy to identify troubled content. TekMOS employs a machine-learning algorithm to create a model from a large set of training images. It then computes scores based on this model without requiring any reference video. The objective TekMOS scores have a very high correlation with the subjective scores gained from visual inspection by human observers.
Highlights
- Finds both quality issues pervasive throughout the content, and quality issues present for shorter durations within the program
- Graphical results make it easy to visualize the quality scores and determine the reason for low scores (tiling, blurriness, or noise)
- Provides an overall assessment of content quality without having to look at a long list of individual defects
Correlate Information Across Multiple Points & Networks
Whether the distribution and delivery network is linear, OTT, or cloud-based, Sentry provides a single tool for monitoring network performance and identifying issues. Aggregate key data and analytics provide a comprehensive network overview with a common and consistent set of measurements to simplify diagnosis, and reduce the time to remedy complex issues.
Highlights
- QoE and QoS measurements and connectivity solutions for linear broadcast
- Monitor using an appliance, virtual instance, or in the cloud
- Easy integration into 3rd party NMS through a RESTful API
