(DRAFT) Ad Creative Signaling in DASH and HLS
The two most common streaming formats for Adaptive Bitrate Streaming – Dynamic Adaptive Streaming over HTTP (DASH) and HTTP Live Streaming (HLS) – provide mechanisms for ads to be inserted into manifest files. However, there’s often a challenge to properly identify the unique ad asset(s) that are embedded in a manifest. This hampers efforts to ensure delivery and monitoring accuracy.
This document proposes a clear and interoperable signaling mechanism for the signaling of creative assets in DASH and HLS. It enables, for example, unique ad asset identifiers such as those from Ad-ID.org and/or unique in-house ad asset IDs to be captured in original or stitched manifest files.
Goals and Objectives
- Establish a signaling scheme for identifying advertising creatives in media presentations.
- Provide binding definitions for the scheme to DASH MPD carriage mechanisms.
- Provide binding definitions for the scheme to HLS playlist carriage mechanisms.
Project Scope
- A data scheme for signaling the identification of advertisement creative assets that are included within a playback experience described by a DASH manifest and/or HLS playlist.
- Carriage of that data scheme as an EventStream object within a DASH manifest.
- Carriage of that data scheme as EXT-X-DATERANGE tags within an HLS playlist.
- The definition or authority of identifier schemes.
- The semantics or requirements of EventStream objects within a DASH manifest.
- The semantics or requirements of EXT-X-DATERANGE tags within an HLS playlist.
