Cross-Device Data Transmission via Advance Backup Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Peer to Peer (P2P) data transmission technologies are ineffective for data transmission between terminals of different types, such as smartphones and tablet computers, leading to increased data transmission pressure and network bandwidth costs for online video portal websites.
Innovation Solution
A method and system for data transmission that involves sending advance backup data to multiple types of user terminals, allowing an (N+1)th type of terminal to request multimedia files by receiving a link address from N types of user terminals, enabling data acquisition and reducing server load and bandwidth costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional P2P technology is used for data transmission, then data transmission between terminals of the same type is effective, but data transmission between terminals of different types fails
Solution Approach 1:
The patent segments the data transmission process into multiple stages: advance backup phase where data is pre-uploaded to multiple terminal types, and request phase where the (N+1)th terminal type can acquire data from any of the N terminal types. This segmentation allows different terminal types to participate in different stages, resolving the compatibility issue while maintaining transmission reliability.
Solution Approach 2:
The patent introduces a server as an intermediary that coordinates the advance backup data distribution and provides link addresses to the (N+1)th terminal type. The server mediates between the N terminal types that provide backup data and the (N+1)th terminal type that requests data, enabling cross-terminal-type communication without direct P2P connection issues.
2Loss of energy
If conventional P2P technology is used, then network bandwidth cost is reduced for same-type terminals, but server data transmission pressure increases for different-type terminals
Solution Approach 1:
The patent implements preliminary action by having N terminal types upload advance backup data to the server in advance, before the (N+1)th terminal type needs to access it. This pre-positioning of data on multiple terminal types reduces the burden on the server during peak access times, as the server only needs to provide link addresses rather than transmit large amounts of data itself.
Solution Approach 2:
The patent enables self-service by allowing the (N+1)th terminal type to directly acquire data from the N terminal types that have backup data, using link addresses provided by the server. This direct acquisition mechanism allows terminal types to serve each other, reducing the need for server-mediated data transmission and lowering server workload.
3Adaptability or versatility
If advance backup data is sent to N types of user terminals, then data transmission between different terminal types is enabled, but network bandwidth is consumed for initial distribution
Solution Approach 1:
The patent applies universality by designing the advance backup data mechanism to serve multiple functions: it enables cross-terminal-type communication, provides redundancy for data availability, and reduces future transmission loads. The same backup data infrastructure serves both compatibility and efficiency purposes, justifying the initial bandwidth investment through multiple benefits.

AI summary
A method for reducing data transmission pressure of a server and to save network bandwidth resources includes sending advance backup data corresponding to multimedia files to N types of user terminals, where N>1; receiving a data request that is sent by an (N+1)th type of user terminal and is used for requesting a multimedia file; and sending, to the (N+1)th type of user terminal, a link address, of advance backup data corresponding to the multimedia file, in the N types of user terminals, the link address being used for instructing the (N+1)th type of user terminal to acquire, from the N types of user terminals, data corresponding to the multimedia file.
