Dynamic Video Playback Layout for Surveillance Feed Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera surveillance systems with multiple cameras generate numerous video feeds, making simultaneous review of recorded video cumbersome due to the complexity of managing and playing back multiple feeds effectively.
Innovation Solution
A computer-implemented method and system that determines a subset of currently available video feeds based on availability, updates the playback layout accordingly, and plays back only the relevant feeds within the updated layout, ensuring efficient playback by adding or removing feeds based on changes in video interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all video feeds from multiple cameras are played back simultaneously, then complete coverage of all camera perspectives is achieved, but the complexity of managing and reviewing multiple feeds increases significantly
Solution Approach 1:
The system extracts only the relevant video feeds that contain events of interest from the complete set of camera feeds, separating them from the irrelevant feeds. This extraction process reduces the number of feeds that need to be managed and displayed simultaneously, directly addressing the complexity issue while maintaining complete coverage of important perspectives.
Solution Approach 2:
The system applies different quality levels of attention to different video feeds based on their relevance. Feeds containing events of interest receive full playback attention, while feeds without events are excluded or minimized. This local differentiation optimizes the playback experience by focusing resources on important content rather than treating all feeds equally.
2Stability of the object's composition
If a fixed playback layout is used for multiple video feeds, then layout stability is maintained, but the ability to adapt to varying numbers of available video feeds is reduced
Solution Approach 1:
The playback layout is made dynamic rather than static, allowing it to automatically adjust its configuration based on the current number of available video feeds containing events of interest. The system monitors feed availability in real-time and reconfigures the layout accordingly, maintaining stability within each configuration while adapting between configurations as conditions change.
3Reliability
If all video feeds are continuously monitored and displayed, then no event is missed, but the review efficiency and ease of analysis decreases due to clutter
Solution Approach 1:
The system extracts and displays only the video feeds that contain events of interest, removing irrelevant feeds from the playback view. This extraction maintains reliability by ensuring all important events are captured while dramatically improving review efficiency by eliminating visual clutter from feeds without events, allowing operators to focus their attention where it is needed.
Solution Approach 2:
Instead of continuously monitoring and displaying all video feeds (excessive action), the system monitors all feeds for events but only displays the subset containing events of interest (partial action). This approach maintains complete event detection capability while optimizing display resources and operator attention for only the relevant content, thereby improving review efficiency without sacrificing reliability.

AI summary
A system and method for playing back video feeds includes determining from the video feeds a subset of currently available video feeds, determining a playback layout based on the number of currently available video feeds and playing back the subset of currently available video feeds within the playback layout. The system and method further includes determining at least one change in availability in a given video feed of the plurality of video feeds, updating the subset of currently available video feeds based on the at least one change, updating the playback layout based on the updated subset of currently available video feeds and playing back the updated subset of currently available video feeds within the updated playback layout.
