AWS Elemental MediaTailor Documentation

AWS Elemental MediaTailor is a channel assembly and personalized ad insertion service for creating linear OTT (internet delivered) channels using existing video content and monetizing those channels, other live streams, or VOD content with personalized advertising.

Server-side Ad Insertion

AWS Elemental MediaTailor allows you to insert advertising content at the location of the start of a requested stream, prior to delivery. This eliminates the need to build and maintain unique configurations for every type of client device in order to insert personalized ads during video playback. Instead, the service generates and maintains a unique “manifest file” for each viewer, which is used to deliver ad placements that are personalized to the individual. Advertising content is directly inserted into the primary content stream and can be played from the same source location to reduce the risk of buffering caused by high format and bitrate variability during video playback. This also reduces the effects of ad blocking software by making it difficult to distinguish ads from other content.

Media Manifest Manipulation

All content is delivered with a consolidated manifest that can include content and personalized ads in a continuous stream to give viewers a TV-like viewing experience. Support for a range of manifests and formats means your live stream can be viewed on a broad range of devices and players.

Hybrid Measurement and Reporting

AWS Elemental MediaTailor supports the Interactive Advertising Bureau (IAB) level of playback metrics by implementing advertising measurement and reporting from the client side through playback observation APIs deployed on the viewing device. In addition, MediaTailor can report server-side ad metrics for legacy devices where changes to the viewing device is not possible.

Scaling with your needs

AWS Elemental MediaTailor can scale with the number of concurrent viewers, and is designed to provide consistent performance and quality of service for your internet-delivered video content as viewership goes up or down.

Your Choice of Video Workflow Components

With AWS Elemental MediaTailor, you are not limited to specific vendors or solutions, including those components of the video workflow that operate directly with the service: the content delivery network (CDN), ad decision server, and origin server. The service works with many standard CDN or ad decision servers, and works with origin servers accessible over HTTP that can be configured using common video streaming protocol and proper ad markers.

Use Independently or with AWS Media Services

AWS Elemental MediaTailor can be used as a standalone service or integrated with AWS services for live video encoding, VOD processing, just-in-time packaging, or media-optimized storage. Additionally, AWS Elemental MediaTailor is interoperable with other AWS services, such as the Amazon CloudFront CDN.
