Video Stream Playback Control via Selective Area Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices struggle to provide effective playback control for specific segments of video streams, particularly in virtual or augmented reality environments, where users want to review or re-watch specific parts of a live video stream without disrupting real-time viewing.
Innovation Solution
The solution involves segmenting a video stream into multiple display areas, recording and enabling playback control for a subset of these areas, allowing users to pause, rewind, or adjust playback speed within the selected areas while maintaining real-time viewing of other areas, and enabling independent playback control for different users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire video stream is recorded for playback control, then complete playback control is achieved, but storage requirements increase significantly
Solution Approach 1:
The video stream is divided into multiple display areas, and only selected areas are recorded for playback control. This segmentation allows the system to provide playback functionality for specific regions of interest while discarding other areas, significantly reducing storage requirements while maintaining useful playback control capabilities.
Solution Approach 2:
The patent extracts and records only the necessary portions of the video stream (specific display areas) rather than the entire stream. By taking out only the relevant segments that require playback control, the system achieves playback functionality without the storage burden of recording the complete video stream.
2Adaptability or versatility
If playback control is enabled for the entire video stream, then comprehensive review capability is achieved, but processing complexity increases
Solution Approach 1:
By segmenting the video stream into display areas and applying playback control only to selected areas, the system reduces processing complexity. Instead of managing playback state for the entire video stream, the system only needs to process and control specific segments, making the overall system less complex while maintaining review capability.
Solution Approach 2:
The patent applies partial action by enabling playback control for only certain display areas rather than the entire video stream. This partial approach provides sufficient review capability for important areas while avoiding the excessive processing complexity that would result from implementing playback control across the whole stream.
3Loss of information
If all display areas are recorded, then complete scene review is achieved, but storage and processing resources are wasted
Solution Approach 1:
The video stream is segmented into multiple display areas, allowing the system to selectively record only those areas that contain important information. This segmentation ensures that critical scene information is retained while avoiding the waste of resources on recording and processing areas that do not require review.
Solution Approach 2:
Different display areas are treated with different quality levels - areas requiring review are recorded with full quality, while other areas are discarded. This local quality approach ensures important scene information is preserved while optimizing resource utilization by not wasting storage and processing on unnecessary areas.
