Video Bookmark System for Cross-Device Media Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video playback technologies limit the ability to freely and easily transfer and play video content across different devices and formats, lacking seamless continuous playback and device independence.
Innovation Solution
The system generates video bookmarks by receiving and normalizing metadata between user-defined place markers, allowing for the creation, storage, and retrieval of video segments across various devices, with features like metadata extraction, thumbnail generation, and aggregation of bookmarks for unified playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is stored on specific devices or formats, then storage and playback are simplified, but device independence and continuous playback across devices are limited
Solution Approach 1:
The patent introduces video bookmarks as an intermediary data structure that bridges different devices and formats. The bookmark contains normalized metadata that is device-agnostic, allowing video segments to be identified and retrieved across multiple devices without requiring the video content itself to be portable or the devices to be compatible
Solution Approach 2:
The patent creates a copy of video content metadata (timestamps, descriptions, thumbnails) that can be stored and transferred independently of the original video file. This metadata copy enables identification and retrieval of video segments across different devices without moving the actual video content
2Productivity
If metadata is extracted and normalized for video bookmarks, then retrieval and search capability are improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs metadata extraction and normalization in advance when the video bookmark is created, rather than when it is needed for retrieval. This preliminary processing stores the video segment information, timestamps, and thumbnails in a ready-to-use format, enabling fast retrieval without repeated processing
Solution Approach 2:
The patent extracts only the essential metadata needed for bookmark functionality (timestamps, segment descriptions, thumbnails) rather than processing the entire video content. This selective extraction reduces processing time while maintaining retrieval efficiency
Data Source
AI summary
Disclosed herein are systems, methods, and computer-readable media for transmedia video bookmarks, the method comprising receiving a first place marker and a second place marker for a segment of video media, extracting metadata from the video media between the first and second place markers, normalizing the extracted metadata, storing the normalized metadata, first place marker, and second place marker as a video bookmark, and retrieving the media represented by the video bookmark upon request from a user. Systems can aggregate video bookmarks from multiple sources and refine the first place marker and second place marker based on the aggregated video bookmarks. Metadata can be extracted by analyzing text or audio annotations. Metadata can be normalized by generating a video thumbnail representing the video media between the first place marker and the second place marker. Multiple video bookmarks may be searchable by metadata or by the video thumbnail visually.
