Solution Overview

Problem

Existing technologies do not facilitate secure and user-friendly content transmission from a transmitting terminal to a receiving terminal without e-mail software, particularly for devices like TVs, and lack robust authentication methods for diverse services.

Innovation Solution

A content delivery system comprising a transmitting terminal, receiving terminal, and delivery server, utilizing device IDs for identification and secure authentication, enabling content transmission via a network without e-mail software, and employing a database for managing content storage and device-specific IDs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If e-mail software is installed in TV sets to enable content transmission, then content delivery capability is improved, but device complexity and development cost increase

Engineering Contradiction:
Improvecontent delivery capabilityVSAvoidsoftware complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the e-mail software component from the TV set and relocates it to a server system. The TV set becomes a thin client that only needs to access the server via simple network protocols, eliminating the need for complex e-mail software installation and maintenance on the TV device itself.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a server as an intermediary between the TV set and the content delivery network. The server handles all complex e-mail processing, authentication, and content management, while the TV set only needs basic network access capabilities, simplifying the TV device architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If authentication systems are made more secure for diverse services, then security is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveauthentication securityVSAvoiduser operation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a universal authentication system that handles multiple services (e-mail delivery, content download, device registration) through a single integrated authentication server. This allows diverse authentication requirements to be managed centrally without requiring separate authentication mechanisms for each service, maintaining both security and simplicity.

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

Solution Approach 2:

The authentication system automatically manages device IDs, validates credentials, and handles authentication decisions without requiring user intervention for complex security protocols. The system performs self-service authentication operations that maintain security while appearing simple to users.

Inventive Principle:
Principle #25Self-service

3Reliability

If device-specific authentication is implemented for content delivery, then security against unwanted content is improved, but device complexity increases

Engineering Contradiction:
Improvecontent delivery securityVSAvoidauthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex authentication logic from the TV set and places it in the server system. The TV set only needs to store and present its device ID, while all authentication decision-making and validation complexity resides in the server, reducing device complexity while maintaining security.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A transmitting terminal can transmit a content held by itself to a specific receiving terminal having no email software as if using a mailer. The transmitting terminal (10) and the receiving terminal (20) are connected to a delivery server (30) via a network (4). The delivery server (30) comprises: a database (36) for registering the device ID that specifies the receiving terminal (20); a content storage (39) for temporarily storing a content transmitted from the transmitting terminal (10); and table (33, 37) for managing contents separately on a per device ID basis of the receiving terminal. The delivery server (30), when receiving a request from the receiving terminal (20), refers to the tables (33, 27) and transmits to the receiving terminal (20) a content, the transmission destination of which corresponds to the device ID of the receiving terminal (20).
