Media Player Comment Embedding for Precise Video Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia presentations face challenges in integrating text effectively for indexing and finding specific moments, with conventional methods like subtitles, scroll bars, and index points being inadequate for precise navigation and user interaction.
Innovation Solution
A system that embeds metadata within multimedia presentations, allowing users to freely insert, edit, and index text comments, enabling non-linear viewing and precise navigation through a media player with a video panel, controls, and a scrolling comments panel, where users can add, edit, and search comments linked to specific time slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional text integration methods (subtitles, credits) are used in media presentations, then text can be displayed, but the text cannot be searched or used to index the presentation for finding specific moments
Solution Approach 1:
The patent combines text comments with temporal metadata and links them directly to specific moments in the media presentation. This integration allows text to serve dual purposes: display information and provide searchable indexes for navigation, resolving the contradiction between information accessibility and system complexity.
Solution Approach 2:
The patent introduces an intermediary layer of metadata that connects text comments to temporal positions in the media. This intermediary structure enables searchability and indexing without requiring fundamental changes to the media playback system, thus balancing information accessibility with system complexity.
2Measurement precision
If scroll bar with limited throw is used for navigation, then the interface is simple, but small movements advance the presentation several minutes making it difficult to find specific moments
Solution Approach 1:
The patent segments the media presentation into discrete time slots associated with individual comments. This segmentation allows users to navigate directly to specific moments by selecting comments, providing precise navigation without requiring complex scroll bar operations while maintaining interface simplicity.
Solution Approach 2:
The patent adds a temporal dimension to the navigation interface by displaying comments with their associated time slots. This transforms the one-dimensional scroll bar navigation into a two-dimensional interface where users can select specific moments both horizontally (by comment) and temporally (by time slot), achieving precision without sacrificing simplicity.
3Measurement precision
If fast-forward and rewind controls are used, then navigation is simple, but the resolution is insufficient to zero in on specific moments
Solution Approach 1:
The patent performs preliminary action by pre-identifying and marking specific moments in the media presentation with associated comments and time slots. This allows users to directly jump to precise moments without iterative fast-forwarding or rewinding, simultaneously improving moment identification precision and navigation efficiency.
4Measurement precision
If preset index points (scene breaks) are used for navigation, then the system is simple, but the index points are too coarse requiring users to waste time waiting for specific portions
Solution Approach 1:
The patent segments the media presentation into fine-grained time slots associated with individual comments, rather than using coarse scene breaks. This fine segmentation allows users to locate specific moments quickly without waiting through entire scenes, achieving both high index granularity and reduced waiting time.
Solution Approach 2:
The patent enables users to create and add their own comments at specific time slots, making the indexing system self-serviceable. This allows the index granularity to be continuously improved by users based on their specific needs, achieving high precision without increasing system complexity or waiting time.
5Adaptability or versatility
If users can freely insert and edit text comments, then the system is highly adaptable, but the device complexity increases
Solution Approach 1:
The patent implements a self-service system where users can independently insert, edit, and manage their own comments without requiring complex administrative interfaces or system configurations. This user-level self-service approach provides high adaptability while minimizing overall system complexity by distributing the intelligence to individual users rather than centralizing it.
Data Source
AI summary
A method and system for linking a web page to a portion of a video is provided. Users can enter comments into a video that include a start and end time index for identifying a portion of a video. Comments are indexed to the media presentations such that they may be searched and located, thus media playback can be executed from any comment. The system allocates a unique comment track to each user that can be turned on and off at will by users during playback.
