Video Playback System Region Segmentation for HD Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video surveillance systems struggle to effectively display high-definition video feeds from multiple cameras on a single monitor, leading to reduced image quality and poor user experience due to the need for zooming out, which can result in missed details during events, especially when multiple regions of interest are involved.
Innovation Solution
The system divides the original playback image into multiple regions of interest and renders the decoded data of the first video image where a triggering event occurs to a specified playback window, allowing for clearer image details and simultaneous tracking of multiple regions without digital zooming, thereby improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple high-definition video feeds are displayed on a single monitor, then the monitoring coverage is expanded, but the image quality deteriorates due to zooming out
Solution Approach 1:
The patent divides the monitor display into multiple independent playback windows, each capable of displaying a separate video feed at full resolution. This segmentation allows multiple camera feeds to be viewed simultaneously without compromising image quality, as each window maintains the original 1080p resolution independently rather than zooming out to fit multiple feeds on a single display area.
2Measurement precision
If digital zooming is used to enlarge a selected region, then the image quality of the region of interest is improved, but pixel information is lost
Solution Approach 1:
The patent extracts the region of interest from the full video feed and displays it in a separate playback window at its original resolution. Instead of using digital zooming to enlarge the region, the system extracts the ROI and presents it independently, preserving all pixel information while maintaining the ability to focus on specific areas of interest.
3Ease of operation
If manual zooming operation is required, then the user can control the view, but the user may miss sudden events due to lack of time for operation
Solution Approach 1:
The patent pre-configures multiple playback windows corresponding to different camera feeds or regions before events occur. When an event is detected, the system can immediately switch to or highlight the relevant pre-prepared playback window, eliminating the need for manual zooming or switching operations and reducing response time to sudden events.
4Area of stationary object
If multiple regions of interest are present, then the monitoring coverage is improved, but the complexity of tracking all regions increases
Solution Approach 1:
The patent segments the monitoring task into multiple independent playback windows, each dedicated to a specific camera feed or region. This segmentation simplifies tracking by isolating each region in its own window rather than requiring the user to manually track multiple regions within a single complex interface, making it easier to monitor and respond to events across different areas.
Data Source
AI summary
The present disclosure discloses a video playback method, apparatus, and system. The method includes: dividing an original playback image into at least two regions of interest; determining, among the at least two regions of interest, a first region of interest where a triggering event occurs; obtaining decoded data of a first video image displayed in the first region of interest; and rendering the decoded data of the first video image to a specified playback window for playing. Using the video playback method, apparatus, and system according to embodiments of the present disclosure, an original playback image is divided into multiple regions of interest, and an image in a region of interest where a triggering event occurs is displayed separately.
