 ### Use optimal video count API
 
-The Azure Communication Services WebJS SDK introduced the [Optimal Video Count (OVC)](../../how-tos/calling-sdk/manage-video.md?pivots=platform-web) feature in version 1.15.1. OVC informs applications how many incoming videos from different participants can be optimally rendered during a group call. The `optimalVideoCount` property adjusts dynamically based on network and hardware capabilities. Applications should update the number of videos rendered according to the output from OVC. Developers should ensure that their application subscribes to changes in the `Optimal Video Count` in group calls. The optimal video count returns an integer defining the ideal number of videos that can be displayed on a web page. The value from optimal video count (OVC) is updated every 10 seconds.
+The Azure Communication Services WebJS SDK introduced the [Optimal Video Count (OVC)](../../how-tos/calling-sdk/manage-video.md?pivots=platform-web) that informs applications how many incoming videos from different participants can be optimally rendered during a group call. The `optimalVideoCount` property adjusts dynamically based on **network bandwith** and **hardware capabilities**. The optimal video count returns an integer defining the ideal number of videos that can be displayed on a web page. Applications should update the number of videos rendered according to the output from OVC. Developers should ensure that their application subscribes to changes in the `Optimal Video Count` in group calls and adjust the number of videos being rendered on a web page dynamically based on the OVC count.

 You need to reference the feature `OptimalVideoCount` via the feature method of the Call object. You can then set a listener via the on method of the `OptimalVideoCountCallFeature` to be notified when the `optimalVideoCount` changes. To unsubscribe from the changes, you can call the off method. The current maximum number of incoming videos that can be rendered on a web page is **16**. To properly support 16 incoming videos, the computer should have a minimum of 16-GB RAM and a 4-core or greater CPU that is no older than three years old.
