Video Providing System Multi-Angle Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video distribution methods often result in the wastage of resources as only a single final edited video is shared, failing to cater to users' diverse preferences, and do not allow users to view desired parts of videos, especially those recorded from multiple angles or at specific times.
Innovation Solution
A video providing system that groups video files based on position and time information, synchronizes them, and allows users to select and view videos from multiple angles or at desired times through a channel-based interface, enabling seamless playback of event images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only a single final edited video is distributed, then video distribution is simplified, but user preferences with various tastes are not satisfied and resources are wasted
Solution Approach 1:
The patent segments the final edited video into multiple original video files recorded from different cameras at different positions. Instead of distributing only the edited version, the system provides access to the segmented original files, allowing users to select and view specific portions according to their preferences.
Solution Approach 2:
The patent adds a new dimension to video distribution by introducing temporal and spatial selectability. Users can now not only view the final edited video but also select specific time segments and camera positions, transforming the flat video distribution into a multi-dimensional selection system.
2Adaptability or versatility
If all video files from multiple cameras are distributed, then user preference satisfaction is improved, but resource wastage increases due to distributing unnecessary files
Solution Approach 1:
The patent implements a dynamic video distribution system where the set of available video files changes based on user selections. The system dynamically assembles and provides only the necessary video segments corresponding to user-chosen cameras and time periods, rather than statically distributing all possible files.
Solution Approach 2:
The patent extracts and provides only the necessary video segments from the complete set of original files. By extracting specific time-range and camera-position segments based on user preferences, the system avoids distributing unnecessary portions of video data.
3Ease of operation
If video files are grouped and synchronized, then seamless playback is achieved, but system complexity increases
Solution Approach 1:
The patent performs preliminary grouping and synchronization of video files from multiple cameras before actual playback. The system pre-processes the video files to establish temporal alignment and association, so that during playback, users can seamlessly switch between different camera views without complex real-time processing.

AI summary
A video-providing system includes a first grouping unit configured to generate a first group that is a collection of one or more video files; a second group unit configured to group at least a portion of video files from the video files included in the first group; and a providing unit configured to provide video files selected from the video files included in the second group unit.
