Decoupled Metadata and Media Storage Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metadata acquisition solutions often require additional computational and energy resources when recording metadata with video content, leading to inefficiencies in capture devices like action cameras.
Innovation Solution
A system that decouples media and metadata acquisition, allowing metadata to be embedded into an electronic storage container, such as a multimedia container format like MP4, enabling continuous metadata capture alongside intermittent or discontinuous image acquisition, and storing it separately from video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If metadata is recorded together with video content, then context information is captured, but computational resources and energy consumption increase
Solution Approach 1:
The patent separates metadata acquisition from media acquisition by implementing independent acquisition sessions. Metadata can be captured continuously or intermittently through a sensor interface that operates independently from the imaging sensor, allowing context information to be recorded without requiring simultaneous video recording operations.
Solution Approach 2:
The patent introduces an electronic storage container as an intermediary structure that holds both media data and metadata. This container decouples the storage requirements of metadata from media files, allowing metadata to be stored efficiently without being embedded in or requiring simultaneous processing with video content.
2Loss of information
If metadata acquisition runs continuously, then complete context is captured, but device resources are overburdened
Solution Approach 1:
The patent implements dynamic metadata acquisition where the sensor interface can be activated or deactivated based on operational needs. Metadata acquisition sessions can be started and stopped independently, allowing the system to capture complete context information when needed while reducing computational load during periods when full metadata capture is not required.
Solution Approach 2:
The patent allows metadata to be acquired in periodic sessions rather than continuously. The sensor interface can perform metadata acquisition at specific intervals or triggered by specific events, maintaining contextual information completeness while significantly reducing the overall computational burden on the capture device.
3Quantity of substance
If metadata is stored in separate files, then storage efficiency improves, but data association becomes difficult
Solution Approach 1:
The patent uses an electronic storage container as an intermediary that maintains the association between metadata and media data. The container structure allows metadata to be stored separately from media files while preserving their relationship through the container's organizational framework, enabling efficient storage without losing the connection between context information and captured content.
Data Source
AI summary
Media capture apparatus and methods for obtaining metadata. Metadata may be collected and stored in a container independent of audio and/or image (media) content. Some container implementations may be configured to store metadata for a given interval, and media content for a portion of the interval. In action camera implementations, metadata may provide a context related to time, physical conditions of a person, location, surroundings of the video capture. In event recording applications, the metadata container may provide information related to a timeline of the event, environmental conditions, proximity of other capture devices. Metadata may be utilized for processing, viewing, and/or sharing of media content. Individual capture devices may communicate and/or combine metadata to one another in order to expand metadata content. Metadata, video and/or images may be shared between users and/or devices using a container.
