Handheld Multi-Vantage Point Player for Immersive Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional video viewing methods limit viewers to a single vantage point, restricting their ability to choose different angles or perspectives during playback, as the director's selection often fails to align with the viewer's interests.
Innovation Solution
A handheld multi-vantage point player system that captures and synchronizes image data from multiple vantage points, allowing users to select and view video streams from various locations within a venue, including stage, backstage, and spectator perspectives, using a portable device with a display and control system connected to a server for logical control over captured image and audio data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is directed by a single vantage point selection, then the video production is simple and straightforward, but the viewer cannot choose different angles or perspectives during playback
Solution Approach 1:
The video player dynamically switches between multiple vantage points based on user selection, transforming a static single-angle playback system into a dynamic multi-angle system. The player allows users to select from multiple pre-captured video streams representing different camera positions, enabling real-time perspective changes without requiring complex real-time rendering or multiple physical screens.
2Adaptability or versatility
If multiple vantage points are captured and made available, then the viewer can choose from different perspectives, but the system complexity increases significantly
Solution Approach 1:
The system performs preliminary action by capturing and pre-synchronizing multiple vantage points before the viewing event. All camera feeds are captured simultaneously during the event and pre-processed with time synchronization metadata embedded. This allows the playback system to simply retrieve and display the appropriate pre-synchronized video stream without requiring complex real-time synchronization algorithms during playback.
Solution Approach 2:
The system creates digital copies of the event from multiple camera perspectives and stores them as separate video streams. Each vantage point is captured as an independent video file with synchronization metadata, allowing the playback system to select and display the appropriate copy without needing to access or process multiple physical video sources simultaneously.
3Adaptability or versatility
If video segments are posted individually by different users, then diverse perspectives are available, but synchronized multi-vantage point viewing during replay is not possible
Solution Approach 1:
The system uses time synchronization metadata as feedback to align multiple video streams. Each captured video stream includes embedded timing information that indicates its temporal relationship to other streams. During playback, the system uses this feedback metadata to automatically synchronize the display of multiple vantage points, ensuring that events occurring at the same moment are visible across all selected perspectives without manual alignment.
Data Source
AI summary
The present invention relates to methods and apparatus for utilizing a portable handheld device for viewing streaming video captured from multiple vantage points. More specifically, the present invention presents methods and apparatus for controlling the immersive experience through player configurations for viewing image data captured in two dimensional or three dimensional data formats and from multiple disparate points of capture based on venue specific characteristics, wherein the viewing experience may emulate observance of an event from at least two of the multiple points of capture in specifically chosen locations of a particular venue.
