Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and double payments when purchasing content on a mobile terminal and attempting to view the same content on a TV, as existing systems do not efficiently transfer purchased content between devices.
Innovation Solution
A content supply system and method that utilizes a user terminal to purchase content, a content supply server to store purchase information, and a display device to transmit usage authorization, enabling seamless transfer of content from a first content purchased on a user terminal to a second content on a display device, such as a TV, without requiring duplicate purchases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user purchases content through a mobile terminal and attempts to view the same content on a TV, then the user can access content on multiple devices, but the user must make double payments for the same content
Solution Approach 1:
The patent implements a content supply system where purchase information obtained from a mobile terminal is utilized by a display device (TV) to access the same content without requiring a separate purchase. The content supply server stores purchase description information and supplies content to both the mobile terminal and display device based on this purchase information, enabling one payment to grant access across multiple devices.
2Adaptability or versatility
If a user purchases content through a mobile terminal and views the same content on a TV, then content can be accessed on multiple devices, but the system complexity increases due to need for purchase information transfer and authorization
Solution Approach 1:
The patent introduces a content supply server as an intermediary that manages the complex interactions between the mobile terminal and display device. The server stores purchase description information, processes authorization requests, and coordinates content supply to both devices. This intermediary approach simplifies the overall system architecture by centralizing the management of purchase information and authorization logic.
3Loss of energy
If purchase description information is stored and transferred between devices, then content can be shared without double payment, but information management complexity increases
Solution Approach 1:
The patent implements preliminary action by having the content supply server store purchase description information in advance when the user makes a purchase through the mobile terminal. This pre-stored purchase information is then automatically utilized when the display device requests content, eliminating the need for real-time information verification and simplifying the information management process.
