Surveillance Video Timeline With Event Thumbnails for Multi-Channel Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network-based surveillance camera systems lack efficient methods for identifying and searching for specific events across multiple channels, as they do not provide clear indicators of event frequency or occurrence times, and their timeline interfaces are limited in facilitating comprehensive event searches.
Innovation Solution
A video display method and system that analyzes event occurrence and frequency across channels, displaying thumbnail images synchronized with a timeline interface, allowing for efficient search and recognition of event times through markers and thumbnail images, with features like scroll indicators and partial image cropping for optimal display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a timeline interface is displayed to provide convenience in video search, then video search convenience is improved, but the existing timeline interface cannot support efficient searching throughout multiple channels for specific events
Solution Approach 1:
The patent combines multiple channel timelines into a single unified timeline interface, merging the separate timeline displays of individual channels into one comprehensive view that shows events from all channels simultaneously, enabling efficient multi-channel event search
2Ease of operation
If videos for each channel are displayed through separate interfaces, then channel-specific video confirmation is improved, but the interface fails to indicate which channel has high occurrence frequency of events
Solution Approach 1:
The patent merges multiple channel interfaces into a single unified interface that consolidates video feeds and event information from all channels, allowing users to view all channels simultaneously while preserving channel-specific details and adding event occurrence frequency indicators
Solution Approach 2:
The patent uses color-coded markers and visual indicators to represent different channels and event types, with color variations indicating event occurrence frequency, allowing users to quickly identify which channels have high event activity through visual differentiation
3Loss of information
If all thumbnail images are displayed in the thumbnail area, then complete event information is provided, but the display becomes inefficient and systematic when the number of thumbnail images is large
Solution Approach 1:
The patent segments the thumbnail display area into multiple sections or pages, dividing the large number of thumbnail images into manageable groups that can be navigated systematically, reducing display complexity while maintaining access to all event information
Solution Approach 2:
The patent implements dynamic thumbnail display that automatically adjusts the number and arrangement of displayed thumbnails based on the current view, allowing the interface to adapt between showing fewer larger thumbnails and more smaller thumbnails as users navigate through different time periods or event types

AI summary
A video processing system including: at least one camera configured to obtain video data; a display interface; and a video analyzer including a memory storing instructions, and a processor configured to execute the instructions to: receive a video data from at least one camera; identify a plurality of video frames in which events occur from the received video data; generate a plurality of thumbnail images respectively representing the plurality of video frames; display a timeline interface indicating respective times of the events via a plurality of markers; and provide the plurality of thumbnail images in a thumbnail area adjacent to the timeline interface respectively corresponding with the plurality of markers, where left ends of the plurality of markers indicate start times of the events, and left ends of the plurality of thumbnail images coincide with the left ends of the plurality of markers.
