Broadcast Receiver Server Backup XML Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadcast receiving apparatuses, such as TVs, lack the ability to store and restore environmental settings, resulting in lost user preferences when the device is upgraded, initialized, or replaced.
Innovation Solution
A broadcast receiving apparatus connected to a server via an interface unit, with a storage unit and control unit that allows for the backup and restoration of settings in XML format, enabling the transmission and storage of user information and settings, even across external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If environmental information is stored locally in the broadcast receiving apparatus, then the device can operate with customized settings, but the information is lost when the device is replaced or initialized
Solution Approach 1:
A server acts as an intermediary between the broadcast receiving apparatus and the environmental information. The server stores backup environmental information received from multiple devices, enabling information preservation across device replacements without directly coupling the devices
Solution Approach 2:
The system creates a copy of the environmental information and stores it on a remote server. This copy serves as a backup that can be restored when the original device is replaced or reinitialized, ensuring information persistence independent of the physical device
2Reliability
If environmental information is transmitted to a server for backup, then information can be restored after device replacement, but network dependency increases
Solution Approach 1:
The system performs preliminary backup of environmental information to the server before device replacement occurs. This advance preparation ensures that when restoration is needed, the information is already available on the server, eliminating the need for complex real-time synchronization mechanisms
3Reliability
If all environmental information is backed up to server, then complete restoration is possible, but data transmission time increases
Solution Approach 1:
The system extracts and transmits only the necessary environmental information to the server for backup, rather than backing up all possible data. This selective approach reduces transmission time while maintaining the completeness of essential restoration data

AI summary
A broadcast receiving apparatus is provided, which includes an interface unit connected to a server; a storage unit storing information on the broadcast receiving apparatus, a display unit displaying a UI (User Interface) for selecting the information on the broadcast receiving apparatus, and a control unit controlling the interface unit to transfer the information on the broadcast receiving apparatus selected through the UI to the server.
