Multimedia Content Signature Matching for Cross-Device Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication tools, such as web browsers and search engines, do not provide an efficient way for users to access and view multimedia content captured on a mobile device at a later time or from a different device, as URLs and bookmarks are dynamic and do not allow for seamless cross-device content retrieval.
Innovation Solution
A system and method that captures multimedia content from a mobile device, generates a signature for the content, and matches sequentially relevant content items based on this signature, enabling users to access the content or related items from any device at a later time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If URLs and bookmarks are used to access web content, then users can save and retrieve content locations, but the content may have changed or the URL may be invalid due to dynamic changes
Solution Approach 1:
The system creates a snapshot copy of the multimedia content at the time of capture, storing it with a generated signature. This copy mechanism ensures that even if the original URL changes or the content is removed from the web, the captured content remains accessible through the signature-based retrieval system.
2Ease of operation
If content is viewed on one device, then the user can access it on that device, but accessing the same content on a different device requires manual search and location
Solution Approach 1:
The system generates a universal signature for the multimedia content that can be used to retrieve the content from any device connected to the network. The signature acts as a device-independent identifier, allowing users to access their captured content on any device without manual search, effectively making the content access system universal across multiple devices.
3Measurement precision
If a signature is generated for the captured multimedia content, then the content can be accurately identified and retrieved, but the signature generation and matching process increases system complexity
Solution Approach 1:
The system extracts essential identifying features from the multimedia content to create a compact signature representation. This extraction process isolates the key characteristics needed for identification while removing redundant information, achieving accurate content identification with reduced computational complexity compared to analyzing the full multimedia content.

AI summary
A method and system for matching sequentially relevant content to at least one multimedia content item (MMCI) captured by a mobile device are provided. The method comprises receiving from a mobile device the MMCI captured by at least one sensor of the mobile device; generating a signature for the captured MMCI; and matching at least one sequentially relevant content item respective of the signature of the captured MMCI.
