AWS Elemental MediaTailor now supports program rules in Channel Assembly

With AWS Elemental MediaTailor Channel Assembly you can now apply program rules to dynamically change the source depending on a viewer ID. Previously, if you wanted to target multiple audiences with changes to your channel schedule, you had to create multiple channels. You now have the ability to create a primary channel with program rules that can be adjusted based on audience, market, geography, subscription level, cohort, content rating and more. Using Channel Assembly with MediaTailor, you can create linear channels that are delivered over-the-top (OTT) in a cost-efficient way, even for channels with low viewership. You can create virtual linear streams with a low running cost by using existing multi-bitrate encoded and packaged live or VOD content. You can also monetize Channel Assembly linear streams by inserting ad breaks without having to condition the content with SCTE-35 markers.
