Video Perspective Navigation System for Multi-Angle Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video presentation systems are limited to a single perspective, requiring users to watch content multiple times to experience different viewpoints, which is inefficient and time-consuming.
Innovation Solution
A video perspective navigation system and method that allows users to efficiently navigate and experience video content from various perspectives by selecting and switching between multiple access points, using graphics processing to render and transition between different viewpoints, enabling simultaneous presentation of main and navigation areas with different perspectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is presented from a single perspective, then the presentation is simple and easy to implement, but the user cannot experience different viewpoints and must re-watch content multiple times
Solution Approach 1:
The video content is segmented into multiple perspective streams, with each stream representing a different viewing angle. The system divides the single video source into concurrent multi-perspective streams, allowing users to access different viewpoints simultaneously without re-watching the entire content.
Solution Approach 2:
The system adds a temporal dimension to perspective switching by providing random access points within the video stream. Instead of linear sequential viewing from one perspective, users can jump to different time-perspective combinations, experiencing multiple viewpoints within a single viewing session.
2Adaptability or versatility
If video content is replayed from different perspectives sequentially, then different viewpoints are provided, but the user must wait through entire presentations before accessing alternative perspectives
Solution Approach 1:
Multiple perspective streams are prepared and encoded in advance during video production. Access points for different perspectives are pre-established within the video stream, allowing users to directly jump to desired perspectives without waiting for sequential replays or processing delays.
Solution Approach 2:
The system maintains continuous playback of the video content while enabling perspective switching. Multiple perspectives are rendered concurrently in the background, and the user interface allows seamless transition between them, ensuring the video content continues to play without interruption while providing efficient perspective access.
3Loss of time
If multiple perspective streams are processed and rendered concurrently, then users can access different viewpoints efficiently, but the computational complexity and processing requirements increase
Solution Approach 1:
The system extracts only the necessary perspective information at the user's requested access points rather than processing and rendering all possible perspectives continuously. By pulling specific perspective data from pre-encoded streams at designated access points, the system reduces computational overhead while maintaining efficient perspective switching.

AI summary
A video navigation system and method can be utilized to efficiently and adjustably navigate video content. In one embodiment, a video information control method facilitates efficient video navigation. A video stream is received and video access point selection between multiple access points in said video stream is controlled. The presentation information is forwarded for each of the multiple access points. In one exemplary implementation, the presentation information is forwarded to a display and the information is directed to presenting a main viewing area and navigation areas that present looping video clips or portions of the video stream at time intervals ahead of and behind the video portion being presented in the main viewing area.
