A/V Recording Device Local Packet Storage for Video Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current A/V recording and communication devices often fail to capture high-quality audio/video footage due to lost packets in the data stream, and frequent recharging of battery-powered devices is inconvenient due to large power draws from uploading all lost data packets.
Innovation Solution
Storing copies of lost data packets at a local storage device and uploading them to a remote storage device using a reliable data transfer protocol, and uploading only a portion of the lost data packets, such as the initial portion of the event that triggered motion detection, to conserve battery power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all lost data packets are uploaded to remote storage device, then complete recording quality is improved, but battery power consumption increases
Solution Approach 1:
The patent applies partial action by uploading only a selected portion of lost data packets rather than all lost packets. The system identifies and uploads critical packets that are essential for maintaining recording quality while omitting less critical packets, thereby reducing the total data transmission volume and battery power consumption while still achieving acceptable recording completeness.
Solution Approach 2:
The system changes the parameter of data packet selection criteria for upload. Instead of uploading all lost packets uniformly, it applies different prioritization parameters based on packet importance, timing, and content criticality. This selective approach optimizes the balance between recording completeness and power consumption by adjusting which packets are retransmitted.
2Reliability
If lost data packets are retransmitted, then recording quality is improved, but data transmission time increases
Solution Approach 1:
The patent implements partial retransmission by selecting only the most critical lost data packets for retransmission rather than attempting to recover all lost packets. This selective approach reduces the total retransmission time while maintaining sufficient recording quality by focusing on packets that have the greatest impact on overall data integrity.
Solution Approach 2:
The system employs feedback mechanisms where the remote storage device or receiving end provides information about which data packets are most critical or which losses have the greatest impact on quality. This feedback guides the selection of which lost packets to retransmit, optimizing the balance between recording quality and transmission time by retransmitting only the packets that will provide the most benefit.
Data Source
AI summary
The present embodiments solve the problem of low-quality stored footage from video stream by storing copies of data packets at a local storage device of the A/V recording and communication device. The locally stored data is subsequently (e.g., after the live stream has terminated) uploaded to a remote storage device. If any data packets are lost during the upload process, those lost data packets can be re-sent from the local storage device to the remote storage device so that the complete recording can be stored at the remote storage device. The subsequent upload process may, in some embodiments, comprise a reliable data transfer protocol.
