With ad prefetching, Zype Playout Scheduler can proactively fetch ads from the ad decision server (ADS) and prepare them for upcoming ad breaks. Ad prefetching helps to maximize ad fill rates and monetization in live workflows that use SCTE-35 signaling, where ad request and transcoding timeouts can occur. Ad prefetching provides more time for programmatic ad trading.
You can enable ad prefetch in you HLS Destination details by clicking the "Ad Prefetch" toggle. You can also customize the Prefetch Retrieval Time - how much time in advance the request to the ADS will be made - to either be Default (which is 120 seconds) or choose from a range between 60 and 300 seconds.
