Timeline Video Interface for Context-Rich Alert Review
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video monitoring systems lack efficient and informative user interfaces for presenting live and saved video feeds, providing inadequate context and control flow for users.
Innovation Solution
A method involving an electronic device with a user interface divided into regions for displaying live video streams and corresponding timelines, allowing users to transition between time spans and view subsets of video frames, along with a server system that selects and encodes non-contiguous video frames for efficient transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional video monitoring interfaces are used, then the system is simple to implement, but the user interface provides inadequate context and control flow information
Solution Approach 1:
The user interface is segmented into multiple functional regions: a video display region showing live or recorded footage, a timeline region displaying temporal information and navigable events, and a controls region providing contextual actions. This segmentation allows each region to specialize in presenting specific types of information without overwhelming the user, thereby reducing information loss while managing interface complexity.
Solution Approach 2:
The patent introduces a temporal dimension to the video monitoring interface through the timeline region. Instead of only spatial navigation (play/pause/stop), the timeline adds a fourth dimension (time) that allows users to navigate, scrub, and understand the temporal context of events. This dimensional addition provides comprehensive context information while maintaining intuitive control through familiar temporal metaphors.
2Productivity
If the entire video stream is transmitted continuously, then the user can view live video without interruption, but the bandwidth consumption and data transmission load increase significantly
Solution Approach 1:
The system extracts and transmits only relevant portions of the video stream based on user interactions with the timeline. When a user selects a specific time range or event, only that extracted segment is transmitted to the client device. This extraction principle significantly reduces bandwidth consumption by eliminating unnecessary video data transmission while maintaining high productivity through on-demand delivery of relevant content.
Solution Approach 2:
Instead of continuous video stream transmission, the system implements periodic action by transmitting video segments only when triggered by user interactions with the timeline. The transmission occurs periodically based on user navigation actions (scrubbing, seeking, event selection) rather than continuously, thereby reducing bandwidth consumption while preserving video review efficiency through responsive on-demand delivery.
3Ease of operation
If the user interface provides detailed timeline and control information, then user satisfaction improves, but the interface complexity and development effort increase
Solution Approach 1:
The timeline component serves multiple functions simultaneously: it acts as a visual time indicator, a navigable control interface, an event display mechanism, and a context provider for video playback. By making the timeline multi-functional, the system improves ease of operation through a single unified interface element while avoiding the need to add separate complex controls, thereby managing interface structure complexity effectively.

AI summary
A method at an electronic device with a display includes: displaying a user interface having a first region and a second region; receiving, and displaying in the first region of the user interface, a live video stream of a physical environment captured by a remote video camera, where at least some of the live video stream is recorded at a remote server; displaying, in the second region, a timeline corresponding to a timespan for a first portion of a duration during which the live video stream may have been recorded; in response to receiving a user interaction to move the timespan to a second portion of the duration, transitioning the displayed timeline to a new timeline that corresponds to the timespan for the second portion, and while transitioning, displaying, in the first region, a subset of video frames representing the first and/or second portion of the duration.
