Device-ID Content Delivery for TVs Without Email Software
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content delivery systems for TVs lack the ability to securely transmit content to a specific receiving terminal without e-mail software, and existing authentication methods are not user-friendly or secure enough for diverse services.
Innovation Solution
A content delivery system comprising a transmitting terminal, receiving terminal, and delivery server, where the server registers device IDs for receiving terminals, manages content storage, and performs secure authentication using device IDs for easy content transmission.
Engineering Contradictions & Design Principles
Engineering 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 development cost and device complexity increase
Solution Approach 1:
The patent extracts the authentication and content delivery functionality from the receiving terminal (TV) and relocates it to the service delivery server. The TV only needs to function as a display device, while the server handles device ID verification, authentication signaling, and content delivery coordination, thereby eliminating the need for e-mail software installation on the TV.
Solution Approach 2:
The service delivery server acts as an intermediary between the transmitting terminal and the receiving terminal. It manages the authentication process using device IDs, coordinates content delivery, and eliminates the need for direct communication protocols (like e-mail software) between terminals and the TV.
2Reliability
If authentication signaling is implemented between service receiving device and service delivery server, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The authentication process is automated through self-service mechanisms. The receiving terminal automatically transmits its device ID to the service delivery server for verification, and the server autonomously completes the authentication signaling process without requiring manual user intervention, thus maintaining high security while ensuring ease of operation.
Solution Approach 2:
Device IDs are pre-registered and stored in the service delivery server before actual content delivery occurs. This preliminary setup enables rapid, automated authentication during content delivery without requiring users to manually input authentication information, balancing security requirements with operational simplicity.
3Reliability
If device ID registration and authentication signaling are implemented, then content security is improved, but system complexity increases
Solution Approach 1:
The patent extracts the complex authentication and device ID management functionality from the terminal devices and centralizes it in the service delivery server. This reduces the complexity burden on individual terminals (especially TVs) while maintaining robust security through centralized control and verification mechanisms.

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).
