Video Feed Timeline Event Overlays for Multi-Camera Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video surveillance systems fail to effectively alert users to pertinent information in video feeds, particularly when monitoring multiple cameras, as bookmarks or notifications may be missed or misunderstood, leading to a need for improved display methods.
Innovation Solution
A user interface is enhanced with pop-up elements and icons on the video timeline to automatically notify users of events, providing detailed information such as titles, timestamps, and graphical representations, which can be displayed for a duration and adjusted in transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If bookmarks are displayed as a bookmark ribbon tail on the video timeline, then information about events is provided to users, but users may not notice the bookmarks when monitoring multiple video feeds
Solution Approach 1:
The patent applies color changes by displaying bookmarks with different colors or color intensities to represent different event types or priorities. This visual differentiation makes bookmarks more noticeable and informative, allowing users to quickly identify and understand event information without missing them during multi-camera monitoring.
Solution Approach 2:
The patent transitions from traditional timeline-only bookmark display to a multi-dimensional approach by overlaying bookmarks on both the video feed and timeline, and by using visual properties like color, size, and transparency to encode additional information dimensions. This enables users to perceive event information from multiple visual angles simultaneously.
2Loss of information
If users hover over bookmarks to see additional information, then detailed event information is provided, but users may not know what the bookmark pertains to without interaction
Solution Approach 1:
The patent applies preliminary action by pre-displaying key event information (such as event type, timestamp, and brief description) directly on the bookmark visual element before user interaction. This allows users to immediately understand what the bookmark pertains to without requiring hover or click actions, reducing the complexity of user interaction while maintaining comprehensive information delivery.
3Productivity
If multiple video feeds are monitored simultaneously, then comprehensive surveillance coverage is achieved, but the likelihood of missing bookmarks increases
Solution Approach 1:
The patent applies local quality by enhancing bookmark visibility specifically in the regions where video feeds are displayed, using localized visual properties such as semi-transparent overlays on video tiles and synchronized timeline markers. This ensures that bookmark information remains noticeable and detectable even when users are monitoring multiple video feeds simultaneously, maintaining reliability without compromising multi-camera monitoring efficiency.
Data Source
AI summary
There is provided a system and a method for displaying information related to a video feed on a user interface. The video feed corresponding to video captured by a video camera provided at a first location is received and displayed in a first region of the user interface, the user interface rendered on a display of a client device located remotely from the video camera. A video timeline associated with the video feed is displayed in a second region of the user interface. At least one user interface element is superimposed on at least the video timeline and is indicative of occurrence of at least one event associated with the video feed, a position of the at least one user interface element on the video timeline corresponding to a time of occurrence of the at least one event.
