A/V Recording Device Decoupling Streaming and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current A/V recording and communication devices often fail to capture high-quality footage due to limitations in streaming bandwidth and packet loss during data transmission.
Innovation Solution
The solution involves decoupling the streaming A/V signal from the recorded A/V signal, allowing for high-quality video footage to be stored locally and then uploaded to a remote storage device after the communication session has ended, regardless of the network bit rate at the time of streaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If video footage is streamed in real-time during a communication session, then the user can view the footage on their client device, but the video quality degrades due to limited streaming bandwidth and packet loss
Solution Approach 1:
The patent segments the video handling process into two independent pathways: a compressed low-quality stream for real-time viewing during communication sessions, and an uncompressed high-quality stream for post-session upload and archival. This segmentation allows each pathway to be optimized independently for its specific purpose without compromising the other.
Solution Approach 2:
The system performs preliminary recording of high-quality video footage locally during the communication session, storing it in buffer memory before the session ends. This preliminary action ensures that the original high-quality data is captured and preserved, ready for subsequent upload, rather than attempting to stream it in real-time where quality would degrade.
2Manufacturing precision
If high-quality video footage is streamed in real-time, then clear evidence is provided for crime detection, but network bandwidth is exceeded causing packet loss and degraded quality
Solution Approach 1:
The patent extracts the high-quality video recording function from the real-time streaming function. By separating these two functions, the system can maintain high-quality recording locally without being constrained by network bandwidth limitations, thereby ensuring both video quality and transmission reliability are preserved through independent handling of each function.
Solution Approach 2:
The system creates a local copy of the high-quality video footage in the device's memory during the communication session. This copy serves as a reliable backup that can be uploaded afterward, ensuring that the original high-quality data is preserved even if network conditions during the session are poor or unreliable.
3Device complexity
If the same video stream is used for both real-time viewing and remote storage, then system complexity is reduced, but the stored video quality suffers from streaming limitations
Solution Approach 1:
The patent implements segmentation by creating separate processing pipelines: one for real-time streaming (compressed, lower quality) and one for local recording (uncompressed, high quality). Although this increases system complexity compared to a single-stream approach, it resolves the contradiction by ensuring that stored video quality is not compromised by streaming limitations, as each pipeline is optimized for its specific purpose.
