Overview

You can use the TVSDK configuration file (AdobeTVSDKConfig.json) to update the priorities for ad creative selection on VAST/VMAP responses. You can also use this configuration file to define the source URL transformation rules for ad creatives.
When your video player makes a request to an ad server, the VAST/VMAP response usually includes multiple ad creatives ( MediaFile elements), each of which provides a URL to a different container-codec version. In some cases, ad creatives in the VAST/VMAP response each provide a different bitrate for the ad. If you want to specify your own priority and transformation rules for these ad creatives, you can do so in the AdobeTVSDKConfig.json configuration file.
  • Do not change the name of the TVSDK configuration file. The name must remain AdobeTVSDKConfig.json.
  • This file should be hosted on your content delivery network (CDN).
You can specify two types of rules in AdobeTVSDKConfig.json: Priority rules and Normalize rules.
