Abstract: The disclosed embodiments relate to media devices implementing new television standards, such as ATSC 3.0, which includes audio/video essence and metadata/signaling. The disclosed embodiments include techniques for confirming an association between two media devices by augmenting media content with a watermark using an upstream device, wherein the watermark conveys an identifier. The media content is sent from the upstream device to a downstream device and the watermark is detected using the downstream device. The identifier is transmitted to a server upon the detection of the watermark using the downstream device. The server identifies an association between the upstream and downstream devices upon receipt of the identifier from the downstream device.

Abstract: The disclosed embodiments relate to media devices implementing new television standards, such as ATSC 3.0, which includes audio/video essence and metadata/signaling. 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 liar 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.
