Solution Overview

Problem

Existing digital TV services require separate membership registration on each content provider's server for content purchase and playback, which is inconvenient for users.

Innovation Solution

A display device that interfaces with a content server using a virtual account, allowing content purchase and playback without separate membership registration on a content provider's server, by creating or utilizing a virtual account through a control server.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate membership registration is required on each content provider's server, then content security and provider autonomy are maintained, but user convenience and system complexity deteriorate

Engineering Contradiction:
ImproveUser convenienceVSAvoidSystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a virtual account system that acts as an intermediary between users and multiple content providers. The virtual account, managed by a control server, enables users to access content from different providers without registering separately on each provider's server. The control server mediates authentication and account management, allowing seamless content access while maintaining provider autonomy and security.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If separate membership registration is required on each content provider's server, then content provider autonomy is maintained, but registration time and user effort increase

Engineering Contradiction:
ImproveRegistration timeVSAvoidContent provider autonomy
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The virtual account system provides universal access across multiple content providers through a single account mechanism. The control server manages the virtual account to enable access to content from different providers without requiring separate registrations. This multi-functional approach reduces registration time while maintaining content provider autonomy through the intermediary control server.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If a virtual account system is implemented, then user convenience and access simplicity improve, but account management complexity and security requirements increase

Engineering Contradiction:
ImproveAccount management simplicityVSAvoidAccount security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control server acts as a secure intermediary that manages virtual accounts and authenticates users accessing content from multiple providers. This centralized mediation simplifies user operations while maintaining security through controlled authentication processes. The control server verifies user identities and manages account information, ensuring secure access without requiring users to handle complex multi-provider credentials.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The display device includes a user input interface that receives, from a remote control device, a request for a login with a particular account for viewing content; a processor that obtains screen information for viewing the content based on the request for the login with the particular account; and a display configured to display a particular screen according to the obtained screen information during the login with the particular account. When a login is attempted for a first time, the processor may receive an interface response indicating that interfacing with a particular content server has been successfully established through the login using a created virtual account, by interfacing with the control server.
