TL;DR: In this paper, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server, in turn, maps the identifier to an action, such as returning metadata, re-directing the request to one or more other servers, requesting information from another server to identify the media object, etc.

TL;DR: In this paper, the authors describe a method of connecting multimedia content to a network resource using an identifier extracted from a media signal, such as from a digital watermark, perceptual hash, or other machine extracted signal identifier.

TL;DR: A watermark reader device reads a watermark embedded into media content and forwards the watermark information to a router, which then uses the information to find a metadata database identifier and sends the related metadata to the reader device as discussed by the authors.

TL;DR: In this article, a set-top box receives content in an interactive television system and the content is digitally watermarked to include content identifiers, which are used to index corresponding interactive data.

TL;DR: A machine readable code (e.g., digital watermark or bar code) conveyed with objects is used in establishing links to associated electronic resources, such as web pages as mentioned in this paper.
