Video Clip Sharing with Camera Identification and Entitlement Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in easily sharing or commenting on content, such as television programs and movies, using their mobile devices due to inaccurate audio detection and distance limitations.
Innovation Solution
A system that allows users to select and share video clips by generating modified playlists for the selected content, which includes encryption information, ensuring that the shared content maintains the same entitlements and protection as the original content, and can be accessed by entitled devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If audio detection is used to identify content for sharing, then content identification is automated, but accuracy deteriorates when audio cannot be identified or device is not close enough to audio source
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture visual information of the content being shared. Instead of relying solely on audio detection, the system uses the camera to take a picture or video of the content source (TV screen, monitor, etc.), which then serves as the basis for content identification and sharing. This intermediary approach resolves the contradiction by providing accurate content identification without requiring proximity to audio sources.
2Ease of operation
If full video playlists are shared, then complete content is available, but content protection and entitlements cannot be maintained
Solution Approach 1:
The patent segments the complete video playlist into individual video clips that can be independently shared. Instead of sharing the entire playlist, the system allows users to select and share specific portions (clips) from the video content. Each clip is processed individually with its own playlist file, enabling controlled distribution while maintaining content protection. This segmentation approach allows easy sharing of specific content portions while preserving entitlements through individual clip authorization.
Solution Approach 2:
The system dynamically generates customized playlists for each shared clip based on the original video playlist and user selections. The playlist information is adaptively modified to include only the relevant video segments, and encryption keys are dynamically assigned to authorized recipients. This dynamic approach enables flexible content sharing while maintaining protection, as each shared clip has its own customized playlist with appropriate access controls.
3Productivity
If video clips are created and shared in real-time, then user engagement is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-processing the video content into segmentable clips and pre-generating playlist structures before sharing. The video is organized into manageable segments with associated metadata and encryption information prepared in advance. When a user wants to share content, the system can quickly assemble the pre-prepared segments into the desired clip format, reducing real-time processing complexity while maintaining fast sharing capability.
Data Source
AI summary
A user may select, edit, and share a portion of content. An interface may be used to select, edit, or comment on the portion of the content. One or more playlists may be generated for the selected portion of content and may be used to access the selected portion of content.
