The disclosed embodiments include techniques for creating a signaling file that contains metadata and signaling data about the broadcast service being presented. The signaling file may include URLs that can be used to access signaling information for supplementary signaling and content. The signaling also contains a mapping between a first timing system and a second timing system. The first timing system may comprise the watermark timeline represented in interval s and the second timing system may comprise a DASH presentation time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Watermark-based metadata acquisition and processing","description":"The disclosed embodiments relate to media devices implementing new television standards, such as ATSC 3.0, which includes audio/video essence and metadata/signaling.
