Precision Basics
The biggest obstacle to consistently deliver high video quality and a great viewing experience is the Internet itself. The Internet was not designed for video delivery and, unlike private broadcast networks, the Internet is not under your control. In spite of limitations inherent to the Internet, Conviva's Precision increases viewer engagement and retention by guaranteeing that viewers can watch your content at the highest quality the Internet can offer.
High bitrates and low video rebuffering times are the key hallmarks of high video quality, and it is tempting to try to improve one at the expense of the other. However, Precision uses a variety of end-to-end delivery paths to improve bitrates and reduce rebuffering at the same time.
Precision continuously monitors video players and uses viewer-centric metrics to infer real-time Internet patterns for end-to-end delivery paths, to empower the multi-CDN algorithms that preemptively optimize quality for each individual view – delivering the best possible video experience to every viewer in real time.

The Precision landing page is the Policies dashboard. This dashboard displays the Precision policies that are defined for your account. For each policy, you see information about the policy (name, the filter and its definition, and when the policy or its filter were last updated).

Precision Policies
Conviva policies govern the CDN switching decisions to optimize QoE with CDN cost management. Policy constraints enable different policy models for the most optimized switching methods:
-
Distribution Policies
-
Restricting predefined traffic shares between resources so only the best CDN in a delivery pattern gets more traffic there. (quality driven)
-
Allowing custom traffic shares, which may be ignored when custom QoE deterioration delta is reached. (constrained optimization)
-
-
Throttling Policies
-
Limit traffic on a specific resource to a custom throttling threshold.
-
-
Optimization Logic
-
Using only the most recent 5 minutes of data, where last minute weighs more than the minute before, and so on. (Failure Detection Module)
-
Evaluating different KPIs in sequence and at different thresholds. (Failure Detection Module)
-
Using more historical data, where more recent data weights more. (Baseline Optimization)
-
Optimizing for a KPI which can be composed of single or combined QoE metrics. (Baseline Optimization)
-
-
Blacklisting Logic
-
When Precision determines a primary resource meets the backlisted requirements, it simultaneously blacklists the resource and starts the blacklisting window.
-
Precision tracks the start and end times of the blacklisting window based on the blacklisting window duration, expressed in minutes.
-
The blacklisting requirements used for evaluating blacklisting events for VPF is based on the number of ended plays during the blacklisting window.
