Path-Enhanced Recorder Integrating GPS and Timestamps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer-oriented multimedia recording devices lack the ability to effectively combine multimedia data with associated time and location information, limiting their functionality in applications that require path-based recording and presentation.
Innovation Solution
A "path-enhanced" recorder that integrates multimedia data capture with path information, using GPS and internal clock data to associate time and location stamps with recorded media, enabling the creation of multimedia files that include spatial and temporal context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If consumer multimedia recording devices record only basic multimedia data without path information, then the device complexity remains low and ease of operation is maintained, but the functionality and adaptability for path-based applications are limited
Solution Approach 1:
The patent combines multiple recording functions (multimedia data capture, GPS location tracking, time stamping) into a single integrated system. The recorder simultaneously captures video/audio data and associates it with path information from GPS and temporal data from an internal clock, merging these previously separate functions into one unified device that produces path-enhanced multimedia recordings
Solution Approach 2:
The recording device is designed to perform multiple functions: capturing multimedia data (video, audio), recording path information via GPS, timestamping data with internal clock, and storing all information in an associated manner. This multi-functional approach enables the device to serve various applications including geological exploration, military reconnaissance, and general media documentation with spatial-temporal context
2Loss of information
If path information is integrated with multimedia data, then spatial and temporal context is enhanced, but the quantity of data stored increases
Solution Approach 1:
The patent segments the recorded data into distinct but associated components: multimedia data packets, path information (GPS coordinates), and temporal information (time stamps). Each component is recorded separately but linked through synchronization mechanisms, allowing the system to maintain complete spatial-temporal context while organizing data in a structured manner that facilitates efficient storage and retrieval

AI summary
A “path-enhanced” recorder combines the recording of multimedia data files (typically, but not necessarily, using conventional digital audio, photo, and video recording technology), along with quasi-continuous capturing of time and position data to permit a subsequent reconstruction of the user's entire path, preferably including times and/or locations at which no multimedia data files were being recorded. A “path-enhanced” recorder device thus provides a combined record of not only multimedia data files but also data concerning path traveled between (and possibly during) the capturing of individual recorded media files to thereby create “path-enhanced” multimedia, which in turn facilitates a number of contemplated applications including the Automatic Generation of Presentations; Exploration, Enhancement and Editing of “Path-Enhanced” Multimedia; and Searching of “Path-Enhanced” Multimedia Databases.
