Master Terminal Multimedia Update Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face significant inconvenience and burden in updating programs for multiple unit terminals in multimedia systems, especially when terminals are supplied by different vendors, due to the need for manual intervention and security concerns regarding program leakage.
Innovation Solution
A multimedia system architecture where a single master unit terminal manages the update process for other slave unit terminals, communicating with a server to acquire and distribute necessary updates, reducing user intervention and ensuring security through encryption and checksum-based verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual update methods (CD/DVD or visiting supplier) are used for each unit terminal, then program update security is maintained, but user convenience deteriorates significantly
Solution Approach 1:
A server acts as an intermediary between the user's terminal and the program update source. The server manages the update process automatically, receiving requests from the terminal, verifying update necessity, and transferring only necessary update data. This eliminates the need for users to manually handle update media or visit suppliers, significantly improving convenience while maintaining security through server-controlled updates.
2Ease of operation
If centralized update management is implemented, then user convenience is improved, but system complexity increases
Solution Approach 1:
The terminal performs self-service by automatically detecting its own program version, comparing it with the latest version information from the server, and initiating updates without user intervention. The system uses built-in update management functions that automatically handle the entire update process, including version comparison, update decision-making, and data transfer, thereby simplifying user operation while managing system complexity through automation.
3Reliability
If program updates are restricted per supplier for security, then program leakage is prevented, but user freedom in updating deteriorates
Solution Approach 1:
The server provides universal update management functionality that serves multiple terminals from different suppliers through a single integrated system. The server maintains separate program databases for different suppliers while providing a unified update interface. Users can update programs from any supplier through the same server, gaining freedom of choice without compromising security, as the server controls all update processes and verifies program authenticity before transfer.
Data Source
AI summary
A multimedia system includes a master unit terminal and slave unit terminals. The master unit terminal functions as an interface for communications with an external server, in which status a program updating process is executed between the server and the slave unit terminal. In the multimedia system, property information on the slave unit terminal is acquired when the master unit terminal is connected to the slave unit terminal on a communication-enabled basis, an update program for the slave unit terminal is acquired from the server via the master unit terminal on the basis of the property information, and thereafter the updating process is executed. This scheme in the multimedia system enables troublesomeness felt by a user to be reduced to the greatest possible degree and security for updating the program of the unit terminal to be guaranteed.
