AI Technical Summary

Benefits of technology

The patent text describes techniques for signaling resource identifiers, particularly using watermarks, to increase security when resource identifiers are signaled. The techniques can be used in any transmission standard, such as DVB, ATSC, or DTMB standards. The patent also describes a method for constructing a request for supplemental content by forming a resource identifier including the authority and path components of a watermark message. Additionally, the patent describes a method for signaling opaque user data in a watermark message payload, where the number of bits of the syntax element indicating the length of the message block payload is based on the message block type.

Problems solved by technology

Current techniques for signaling information associated with digital media content may be less than ideal.

Embodiment Construction

[0015]Computing devices and / or transmission systems may be based on models including one or more abstraction layers, where data at each abstraction layer is represented according to particular structures, e.g., packet structures, modulation schemes, etc. The Open Systems Interconnection (OSI) model defines a 7-layer stack model, including an application layer, a presentation layer, a session layer, a transport layer, a network layer, a data link layer, and a physical layer. It should be noted that the use of the terms upper and lower with respect to describing the layers in a stack model (e.g., a content delivery protocol model) may be based on the application layer being the uppermost layer and the physical layer being the lowermost layer. Further, in some cases, the term “Layer 1” or “L1” may be used to refer to a physical layer, the term “Layer 2” or “L2” may be used to refer to a link layer, and the term “Layer 3” or “L3” or “IP layer” may be used to refer to the network layer. ...

Abstract

A device may be configured to signal information using watermarks. A device may be configured to determine an identifier associated with an address of a resource associated with multimedia content and embed the identifier in a signal representing multimedia content. A device may be configured to receive a multimedia signal, parse an identifier associated with an address of a resource from the multimedia signal, generate a query including the identifier, and receive supplemental content in response to the query.
