Solution Overview

Problem

There is a lack of effective methods to protect the copyrights of content and linked applications in ACR services, particularly in the United States where data broadcast bands are not established for TV broadcast signals, leading to potential unauthorized use and infringement of rights.

Innovation Solution

An information processing device and method that manage content and applications by generating reference data associating signature data with content identifiers and right management information, enabling secure identification and execution of linked applications while respecting copyright holders' rights, using a database to store and decrypt signature data for authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If ACR services are implemented without right management information, then content identification and application execution are simplified, but copyright infringement and unauthorized use occur

Engineering Contradiction:
ImproveACR service implementationVSAvoidcopyright infringement
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by embedding right management information and signature data into the content before distribution. The ACR server pre-registers reference data including signature data, content identifiers, and right management information in a database, so that when content is viewed, the system can automatically authenticate and enforce copyright without complex real-time verification processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism through the ACR server and its database that mediates between content users and copyright holders. The server acts as a trusted third party that verifies signature data against registered reference data, checks right management information, and controls application execution permissions, thereby preventing unauthorized use while maintaining ease of operation for legitimate users.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If signature data is extracted and used for ACR services, then content identification is enabled, but unauthorized ACR services and rights infringement may occur

Engineering Contradiction:
Improvecontent identificationVSAvoidauthorization control
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary action by extracting signature data from content during the content creation or distribution phase and pre-registering it in the ACR server's database along with associated right management information. This allows the content to be identified later through matching operations while ensuring that authorization control is established beforehand, preventing unauthorized ACR services.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by creating a closed-loop verification system where the ACR server compares extracted signature data against registered reference data, checks right management information, and provides authentication results that control subsequent application execution. This feedback mechanism ensures that only authorized content receives ACR services, maintaining reliability while enabling versatile content identification.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If linked applications are executed automatically with content, then user convenience is improved, but application rights infringement may occur

Engineering Contradiction:
Improveapplication executionVSAvoidapplication rights infringement
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary control mechanism where the ACR server acts as a mediator between content playback and linked application execution. The server verifies right management information associated with both the content and the linked application before permitting execution. This intermediary layer automatically enforces application rights while maintaining user convenience, as the verification occurs transparently in the background without requiring user action.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system applies preliminary action by pre-registering right management information for linked applications in the ACR server's database during content distribution. Before execution, the system automatically checks whether the user has proper authorization for both the content and the associated application. This preliminary setup enables automatic, convenient execution for authorized users while preventing rights infringement without requiring complex real-time user permissions management.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present disclosure relates to an information processing device and an information processing method for realizing an ACR service without any infringement of the rights of the respective holders of the copyrights to content and the linked application. An information processing device of the present disclosure includes: a content managing unit that manages first content viewable on the side of a content reproduction device; a database unit that generates reference data and turns the generated reference data into a database by associating first signature data of the first content with right management information about the first signature data and the content identifier representing the first content from which the first signature data has been extracted; and an identifying unit that identifies the content and returns a response indicating an identification result by referring to the database unit in reply to a query including second signature data of second content being viewed by the user of the content reproduction device, the query being transmitted from the side of the content reproduction device. The present disclosure can be applied to ACR services.
