Skip ad breaks for a period of time

By default, TVSDK forces an ad break to play when the user seeks over an ad break. You can customize the behavior to skip an ad break if the time elapsed from a previous break completion is within a certain number of minutes.

To override the default TVSDK ad break behavior, you can extend the default ad policy selector. There are four ad break policies available:

• PLAY

• SKIP

  NOTE

  The SKIP ad break policy might not work as expected for live streams when an ad is present at the live point. For example, for a pre-roll, SKIP will cause a seek to the end of the ad break, which could be greater than the live point. In this case, TVSDK may seek to the middle of an ad.

• REMOVE_AFTER

• REMOVE

  NOTE

  The REMOVE ad break policy is slated for deprecation. Adobe recommends that you use the SKIP ad break policy in place of REMOVE.

The following example of a customized ad policy selector skips ads in the next five minutes (wall clock time) after a user has watched an ad break.

1. When the user finishes watching an ad break, save the current system time.

   @Override
   public void onAdBreakComplete(AdBreak adBreak) {
       ...
       if (isShouldPlayUpcomingAdBreakRuleEnabled()) {
           CustomAdPolicySelector.setLastAdBreakPlayedTime(System.currentTimeMillis());
           ...
       }
   }
   

2. Extend AdPolicySelector.
