Solution Overview
Problem
In surveillance network systems with multiple monitor cameras, it is challenging to promptly identify and focus on target data within video streams, leading to a reduction in the system's effectiveness in real-time monitoring.
Innovation Solution
A method that prioritizes video streams containing specified events by sequencing them based on a weight value system, using an event detection model to identify and adjust the queue, ensuring that critical events are displayed prominently and in real-time, utilizing a video stream processing apparatus with AI capabilities for efficient processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple video streams from monitor cameras are displayed simultaneously, then the surveillance system can monitor all areas, but it becomes difficult to quickly identify and focus on target data
Solution Approach 1:
The patent segments the video streams into different priority levels based on event detection. Video streams containing specified events are separated from normal streams and displayed with different visual characteristics (such as highlighting or separate display regions), allowing operators to quickly identify and focus on critical events while maintaining awareness of all monitored areas.
Solution Approach 2:
The patent employs visual differentiation through color changes or distinct display attributes to highlight video streams that contain specified events. By changing the visual appearance (such as using different colors, borders, or display positions) for video streams with events, the system makes target data immediately distinguishable from normal video streams, solving the difficulty of rapid identification.
2Ease of operation
If video streams are displayed in a fixed queue order, then the system is simple to operate, but critical events may be delayed or missed
Solution Approach 1:
The patent transforms the fixed video stream queue into a dynamic structure that automatically adjusts based on event detection. Video streams containing specified events are automatically prioritized and repositioned in the display queue, while normal streams maintain their original positions. This dynamic reordering ensures critical events are displayed timely without requiring complex manual intervention, maintaining operational simplicity while improving event detection reliability.
Solution Approach 2:
The system incorporates feedback from event detection models that continuously monitor video streams and provide real-time information about detected events. This feedback mechanism automatically triggers priority adjustments in the video stream queue, ensuring that when events are detected, the relevant video streams are immediately prioritized for display, thereby maintaining both simplicity and reliability.
3Device complexity
If all video streams are processed equally, then the processing system is simple, but the surveillance effectiveness is reduced due to inability to focus on critical events
Solution Approach 1:
The patent applies local quality by treating different video streams differently based on their content characteristics. Video streams containing specified events receive enhanced processing and display priorities, while normal streams are processed with standard resources. This differentiated approach increases surveillance effectiveness by focusing computational and attentional resources on critical events without requiring complete system redesign, thus balancing complexity and productivity.

AI summary
A method for optimizing a process of displaying video streams with specified event receives video streams. The video streams are sequenced based on a specified arrangement role to from a video stream queue. By analyzing each video streams, whether each video stream includes a specified event is determined. If each video stream without the specified event, the video streams are outputted based on the video stream queue. If the video stream includes the specified event, the video stream with the specified event is adjusted to be priority in the video stream queue, and the video streams are outputted based on the updated video stream queue. The video streams with the specified event can be prioritized processed and focus. A video stream processing apparatus and a computer readable storage medium applying the method are also provided.
