Video Timed Anchors for Salient-Moment Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Videos cannot be efficiently skimmed for specific content, leading to users spending excessive time searching for key moments, which increases network bandwidth usage and processing resources.
Innovation Solution
Generating video anchors with time indices and textual or visual indicators that allow direct navigation to salient points in videos, using interest criteria tailored to different video types, and selectively including frames or text labels to represent key moments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users manually scrub through video to find key moments, then they can locate specific content, but it consumes excessive time and increases network bandwidth usage
Solution Approach 1:
The system performs preliminary analysis of the video content to identify key moments and generate anchors before the user views the video. This pre-processing creates a structured index of important segments, allowing users to directly navigate to relevant content without manually scrubbing through the entire video, thus reducing both time consumption and network bandwidth usage.
Solution Approach 2:
The patent introduces video anchors as an intermediary layer between the user and the video content. These anchors act as navigation points that represent key moments in the video, enabling users to jump directly to relevant segments without loading or playing unnecessary video data, thereby reducing network bandwidth consumption and access time.
2Reliability
If the entire video is loaded and processed, then all content is available for viewing, but processing resources and network bandwidth are wasted on non-salient segments
Solution Approach 1:
The system extracts only the salient portions of the video content by identifying key moments based on predefined criteria. Instead of processing the entire video, the system pulls out and indexes only the important segments, creating a condensed representation that maintains content availability while significantly reducing processing resources and network bandwidth requirements.
Solution Approach 2:
The patent applies different processing quality levels to different parts of the video. Key moments identified through interest criteria receive full processing and detailed indexing, while non-salient segments are either summarized or excluded from detailed processing. This localized quality approach ensures that processing resources are concentrated on important content while maintaining overall content availability.
3Measurement precision
If video anchors with detailed analysis are generated for all segments, then accurate key moment identification is achieved, but processing time and computational resources increase
Solution Approach 1:
The system applies detailed analysis selectively to only those video segments that meet predefined interest criteria for key moments. Instead of performing exhaustive analysis on the entire video, the system uses efficient filtering mechanisms to identify potentially interesting segments and applies detailed processing only to those candidates, achieving accurate key moment identification while maintaining high processing speed.

AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating video anchors for a video. In one aspect, a method includes obtaining key moment identifiers for a video, where each key moment identifier includes a time index value specifying a playback time in the video, and is indicative subject matter of the video that has been determined to meet one or more interest criteria that define salient topics within the video. For each key moment identifier, a video anchor is generated, where each video anchor indicates a playback time for the video, and may include an image of a frame that occurs near the playback time. Upon a selection of the video anchor by the user, an instruction in the video anchor causes a video player to begin playback of the video at the playback time specified by the video anchor.
