Interactive Video Annotation System With Temporal Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional web-based systems for digital video storage and display lack advanced annotation capabilities, allowing only whole-video commenting and simplistic annotation controls, with restricted access often limited to video owners.
Innovation Solution
A system and method for creating and displaying interactive annotations on online hosted videos, featuring a graphical annotation interface that allows various types of annotations, user authentication for controlled annotation access, and integration with video analysis for automatic annotation suggestions, enabling users to add text, links, and modify video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional web-based systems allow only whole-video commenting, then system simplicity is maintained, but user interaction precision deteriorates
Solution Approach 1:
The video is segmented into temporal portions (time segments) that can be individually annotated. Users can attach comments to specific time segments rather than the entire video, enabling precise location referencing while maintaining a simple comment interface. The system divides the video timeline into discrete annotationable units.
Solution Approach 2:
The annotation system adds a temporal dimension to commenting by introducing time segment identifiers. Instead of single-dimensional whole-video comments, the system creates multi-dimensional annotations that combine spatial (video frame) and temporal (time segment) coordinates, enabling precise portion identification.
2Device complexity
If annotation access is restricted only to video owners, then content control is simplified, but collaborative annotation capability deteriorates
Solution Approach 1:
The annotation access control is made dynamic rather than static. The system can adapt permission levels based on user roles, video settings, and annotation types. Owners can dynamically grant or revoke annotation permissions to specific users or groups, allowing flexible collaboration while maintaining control.
Solution Approach 2:
The system implements partial access control where different users can have different levels of annotation permissions. Instead of all-or-nothing access, users can be granted permission for specific annotation types, time segments, or video portions, enabling nuanced collaborative control.
3Ease of operation
If simplistic annotation controls are provided, then ease of use is improved, but annotation functionality deteriorates
Solution Approach 1:
The annotation system is designed as a universal platform that supports multiple annotation types (text comments, timestamps, links, embedded content) through a single unified interface. The same basic annotation controls can create different types of annotations, providing versatile functionality while maintaining operational simplicity.
Solution Approach 2:
The system allows annotation parameters (such as time segment duration, annotation type, visibility settings) to be changed and customized. Users can modify annotation properties after creation, and the system adapts to different annotation configurations while maintaining a consistent user interface.

AI summary
Systems and methods are provided for adding and displaying interactive annotations for existing online hosted videos. A graphical annotation interface allows the creation of annotations and association of the annotations with a video. Annotations may be of different types and have different functionality, such as altering the appearance and/or behavior of an existing video, e.g. by supplementing it with text, allowing linking to other videos or web pages, or pausing playback of the video. Authentication of a user desiring to perform annotation of a video may be performed in various manners, such as by checking a uniform resource locator (URL) against an existing list, checking a user identifier against an access list, and the like. As a result of authentication, a user is accorded the appropriate annotation abilities, such as full annotation, no annotation, or annotation restricted to a particular temporal or spatial portion of the video.
