Circular Buffer Video Recording Headset for Hands-Free Event Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable video recording (PVR) camera equipment is cumbersome and limited in capturing unexpected events in real-time due to its size and temporal accessibility, often resulting in missed moments as users struggle to initiate recording promptly during unplanned events.
Innovation Solution
A wireless video recording headset with a non-volatile circular video recording buffer that continuously records video, allowing for hands-free operation and automatic overwriting of older frames with new ones, enabling seamless capture of events without the need for manual recording initiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional PVR camera equipment is used, then video recording capability is provided, but the equipment is cumbersome and limits user activities
Solution Approach 1:
The patent divides the video recording system into separate functional components: a wearable camera module that can be detached from the smartphone. This segmentation allows the camera to be worn hands-free during activities while the smartphone handles processing and storage, resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The wearable camera module is designed to work with multiple smartphone models and support various recording modes (video, photos, live streaming). This multi-functionality allows a single device to serve multiple purposes, improving ease of operation without significantly increasing complexity
2Reliability
If manual recording initiation is required, then recording control is precise, but unexpected events are missed due to delayed response
Solution Approach 1:
The system performs preliminary actions by continuously pre-recording video in the background before an event occurs. When the user activates the recording button, the system has already captured the moments leading up to the event, eliminating the time loss associated with manual initiation while maintaining reliability of event capture
Solution Approach 2:
The camera continuously records video footage in the background without interruption, ensuring that no moments are missed. This continuous recording action maintains reliability of event capture while the user can initiate formal recording at any time without worrying about response delays
3Reliability
If continuous video recording is implemented, then no events are missed, but storage capacity is quickly exhausted
Solution Approach 1:
The system automatically discards older pre-recorded video segments when the storage buffer is full, making room for new continuous recording. This discarding and recovering mechanism allows the system to maintain continuous event capture reliability while managing limited storage capacity efficiently
Solution Approach 2:
The system performs partial recording by continuously capturing video but only saving and retaining segments that contain significant events or are explicitly marked by the user. This approach allows continuous monitoring without exhausting storage capacity, balancing reliability with storage constraints
4Ease of operation
If hands-free operation is implemented, then user mobility is improved, but device configuration becomes complex
Solution Approach 1:
The patent merges the camera module with the smartphone's existing processing, storage, and communication capabilities. By combining these functions into an integrated system where the wearable camera leverages the smartphone's resources, hands-free operation is achieved without the complexity of a fully self-contained device

AI summary
A video recording camera system configured to record video to a non-volatile memory configured as a circular video recording buffer. In an embodiment, the video recording camera system includes a non-volatile storage medium and a processor is configured to manage at least a portion of the non-volatile storage medium as a circular buffer, replacing recorded video data stored in a subset of memory addresses corresponding to an older recorded video frame with the data corresponding to a newer video frame. In further embodiments, clip files may be partitioned from the circular buffer to prevent logical portion of the recorded video from being overwritten upon reaching a capacity of the circular recorded video buffer.
