Continuous Content Redirection via Local Position Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia content services risk exposing user location information by periodically transmitting device location data to servers, and they lack automatic content redirection between devices without user preference-based selection.
Innovation Solution
A server and method that analyze position changes between mobile and fixed devices using GPS, determining if content reproduction should continue without transmitting location information, allowing seamless content redirection between devices while protecting user privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If location information of mobile device is periodically transmitted to server for automatic content redirection, then content service continuity is improved, but user privacy protection deteriorates
Solution Approach 1:
The patent extracts the location analysis function from the server and relocates it to the mobile device. The mobile device independently calculates distance and position changes using its own GPS data and the fixed device's location, eliminating the need to transmit location information to the server while maintaining automatic content redirection capability
Solution Approach 2:
The patent introduces distance calculation as an intermediary parameter between location information and content redirection decisions. Instead of directly using location data for server-side decisions, the system converts location data into distance metrics locally, which then serve as the basis for determining content continuity without exposing raw location information
2Ease of operation
If manual selection of reproduction device is required, then user control over content playback is improved, but system complexity and user operation burden increase
Solution Approach 1:
The patent enables the system to automatically monitor service interruption status and initiate content redirection without requiring user intervention. The mobile device autonomously detects when content playback stops at the fixed device and automatically requests continuous reproduction from the server, eliminating manual device selection while maintaining user control through automatic operation
Solution Approach 2:
The patent implements a feedback mechanism where the mobile device continuously monitors whether content reproduction has been interrupted at the fixed device. Based on this feedback, the system automatically determines whether to initiate continuous reproduction requests, creating a closed-loop control system that adapts to user needs without manual input

AI summary
Provided are a continuous contents reproduction service providing server, a user device, and a method of providing a continuous contents reproduction service for continuously providing contents to a plurality of devices. The server may include: a device management unit to store identification information of a first device and a second device; a service interruption monitoring unit to determine whether reproducing of contents in the first device is interrupted; a continuous reproduction information message transceiving unit to generate a continuous reproduction information message when the reproducing of the contents is interrupted, and to transmit the generated continuous reproduction information message to the second device; a continuous reproduction management unit to receive a request for a continuous reproduction service and to determine whether to continuously provide the contents to the second device; and a contents providing unit to provide the contents to the second device based on the determination.
