Time Synchronized Content Sharing via Camera Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content sharing methods require users to have prior knowledge of network addresses and file information, limiting convenient and instant access to multimedia contents in a mobile environment.
Innovation Solution
A device and method that perform time synchronization between devices, allowing users to input a time stamp to retrieve a contents list and select desired multimedia contents without pre-existing knowledge, enabling seamless content sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users share contents using traditional methods requiring network addresses and file information, then content sharing can be achieved, but user convenience and accessibility are reduced
Solution Approach 1:
The patent introduces a camera as an intermediary device that captures visual information about the target device's display. The camera acts as a mediator between the user and the content sharing system, translating visual information into actionable data (coordinates and timestamp) without requiring the user to manually input network addresses or file information. This resolves the contradiction by making content sharing convenient while eliminating the need for prior knowledge.
Solution Approach 2:
The patent replaces the traditional mechanical/manual system of typing network addresses and file paths with an optical system using a camera to capture and recognize visual information. The camera-based approach substitutes manual input mechanisms with automated image recognition and coordinate extraction, significantly improving ease of operation while eliminating information loss associated with manual entry errors.
2Measurement precision
If users manually input network addresses and file information for content sharing, then accurate content retrieval is possible, but time consumption increases
Solution Approach 1:
The system performs preliminary actions by capturing an image of the target device's display in advance. The captured image contains pre-extracted coordinate information and timestamp data that identify the specific content being displayed. This preliminary capture eliminates the need for real-time manual input, reducing time consumption while maintaining accurate content identification through the pre-captured visual data.
Solution Approach 2:
The patent uses a copy of the target device's display (captured via camera) instead of directly accessing the original content through manual input. The captured image serves as a copy containing all necessary identification information (coordinates and timestamp), enabling rapid content retrieval without the time-consuming process of manually entering network addresses and file paths, while maintaining precise content identification.
3Reliability
If the system requires detailed content information for sharing, then content accuracy is improved, but system complexity increases
Solution Approach 1:
The patent extracts only the essential information needed for content sharing (coordinates and timestamp) from the visual display, rather than requiring users to input all possible content details. The camera captures the display and the system extracts only the critical identification data, reducing information input complexity while maintaining content sharing reliability through the extracted coordinates and timestamp that uniquely identify the target content.
Solution Approach 2:
The system performs self-service by automatically capturing and processing the necessary identification information from the target device's display. Instead of requiring users to manually gather and input detailed content information, the camera-based system automatically acquires coordinates and timestamp data, reducing input complexity while ensuring reliable content sharing through automated information collection and processing.
Data Source
AI summary
A device and method of sharing contents based on time synchronization are provided. A first device may generate a time stamp with respect to contents being replayed by a second device and transmit the time stamp to the second device. In response, the second device may generate a contents list based on the time stamp and transmit the contents list to the first device. The first device may request contents selected by a user from among the contents list, and the second device may provide the requested contents to the first device.
