Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission protocols are inefficient for time-critical data in sports events, consuming substantial bandwidth and prone to errors, failing to provide real-time and low-bandwidth solutions.
Innovation Solution
A data transmission method using differential status updates from a server to user devices, employing a tree-structured data set with real-time updates of changed data, ensuring secure and efficient bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If large data packets are transmitted to provide complete data sets, then data completeness is improved, but bandwidth consumption increases and transmission errors occur
Solution Approach 1:
The data set is divided into a tree structure with multiple nodes, allowing selective transmission of only the changed portions (child nodes) rather than the entire data set. This segmentation enables efficient bandwidth usage while maintaining data completeness for updated information.
Solution Approach 2:
Only the changed data portions are extracted and transmitted from the complete data set. The server identifies which child nodes have been updated and sends only those specific changes to the user device, eliminating the need to transmit redundant unchanged data.
2Loss of information
If complete data sets are transmitted periodically, then data up-to-date is improved, but transmission time increases and real-time responsiveness deteriorates
Solution Approach 1:
The transmission system dynamically adapts to data changes by detecting when child nodes are updated and triggering selective transmissions only when necessary. This dynamic approach ensures data remains up-to-date while avoiding unnecessary periodic transmissions of unchanged data.
Solution Approach 2:
The server monitors data changes in real-time and uses this feedback to determine when transmissions are needed. When child node data changes, the system automatically triggers a transmission of only the updated portions, ensuring real-time responsiveness without unnecessary periodic transmissions.
3Loss of information
If data is transmitted to multiple authenticated devices, then data availability is improved, but network complexity and authentication overhead increase
Solution Approach 1:
The server maintains a single authenticated connection and uses it to efficiently distribute data to multiple user devices. The tree-structured data system allows one authenticated session to serve multiple clients, reducing the complexity of managing multiple separate connections while ensuring data availability for all authenticated devices.
Data Source
AI summary
A data transmission method for the transmission of information between a server and at least one authenticated device, and in particular it is directed to a method for transmitting a set of data with a tree configuration over a computer network sending differential status updates from a single source, or server, to a plurality of user devices.
