Multi-source Video Navigation via Segmented Image Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-source video navigation systems face synchronization issues and image quality degradation when switching between video streams, leading to poor user comfort and inefficient resource utilization.
Innovation Solution
A method for multi-source video browsing that receives and synchronizes image parts from multiple video streams, allowing seamless switching between streams without latency, using a single video player to display additional image portions as thumbnails, which are synchronized and compressed, providing a user-friendly interface and efficient resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple video streams are displayed with stream selection capability, then user comfort is improved, but synchronization problems and image quality degradation occur during stream switching
Solution Approach 1:
The video content is segmented into discrete image parts, each corresponding to a specific video stream. The display area is divided into multiple regions showing different image parts simultaneously. This segmentation allows the system to switch between streams by displaying different pre-synchronized image parts without requiring complex real-time synchronization during switching, thus resolving the contradiction between user comfort and synchronization reliability.
2Ease of operation
If stream switching is implemented, then user comfort is improved, but image quality degradation occurs due to terminal resource constraints
Solution Approach 1:
Multiple image parts from different video streams are prepared and synchronized in advance before the user needs to switch streams. Instead of performing resource-intensive real-time processing during stream switching, the system pre-processes and buffers image parts from multiple streams, allowing instantaneous switching without quality degradation. This preliminary action eliminates the trade-off between switching capability and image quality.
3Adaptability or versatility
If multiple video streams are processed simultaneously, then navigation capability is improved, but computing resource consumption increases
Solution Approach 1:
The system merges multiple video streams into a single composite sequence where each frame contains multiple synchronized image parts from different streams. This consolidation allows the navigation function to access multiple streams simultaneously while processing them through a unified playback mechanism, reducing the overall computing resource consumption compared to handling each stream separately while maintaining enhanced navigation capability.

AI summary
A method of multi-source video navigation, comprising: receiving (402) an image sequence, each image of said sequence comprising a plurality of image parts (121, 122, 123, 24, 125, 126), the image parts of said plurality comprising image data arising from synchronized images of respective video streams, each video stream arising from a corresponding source, receiving (414) a selection parameter value (video_ch) arising from a user interface, said value corresponding to one at least of said video streams, and instructing (408) the displaying of the at least one image part, from among the image parts of this plurality, corresponding to the value of the selection parameter received.
