Synchronized Panoramic Video Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for capturing and viewing panoramic videos lack the capability to simultaneously control playback and viewport synchronization across multiple panoramic videos, providing a unified and immersive viewing experience.
Innovation Solution
The use of an array of monoscopic and stereoscopic detectors with processing circuitry to capture and stream panoramic video data, allowing users to control pan, tilt, and zoom independently across multiple video streams, with synchronized playback controls through a user interface that enables seamless switching between different camera feeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple panoramic video streams are captured and displayed simultaneously, then the viewing experience becomes more immersive and versatile, but the system complexity and difficulty of synchronization increase
Solution Approach 1:
The system divides the panoramic video processing into independent streams, where each panoramic video stream is processed separately through its own buffer and control mechanisms. This segmentation allows multiple panoramic videos to be handled simultaneously without overwhelming system complexity, as each stream can be independently managed while maintaining overall synchronization through the common user interface.
2Adaptability or versatility
If users can independently control pan, tilt, and zoom for each video stream, then the viewing flexibility increases, but the control complexity and synchronization difficulty increase
Solution Approach 1:
The user interface implements universal control mechanisms that work across all panoramic video streams simultaneously. The same control inputs (pan, tilt, zoom adjustments) are applied uniformly to multiple video streams, providing viewing flexibility while simplifying operation. Users control multiple streams through a single unified interface rather than managing each stream separately, reducing control complexity while maintaining independence of each video feed.
3Ease of operation
If playback controls allow rewinding, pausing, and forwarding through buffered video, then user interaction capability improves, but the synchronization maintenance across multiple streams becomes more difficult
Solution Approach 1:
The system implements feedback mechanisms where playback control actions (rewind, pause, forward) on one panoramic video stream automatically reflect across all other synchronized streams. The user interface monitors and propagates playback state changes throughout the system, ensuring that when a user pauses one stream, all other streams pause at the corresponding timestamp. This feedback loop maintains synchronization reliability while preserving full user interaction capability.

AI summary
An apparatus and method are provided for viewing panoramic images and videos through the selection of a particular viewing angle and window (zoom) within that panorama while allowing the viewer to simultaneously implement temporal transport control, allowing the video to be in a state of pause, play, fast forward, fast rewind, slow forward, slow rewind, or frame-by-frame. This capability may be used on video that is residing in memory on the viewer's viewing system, in a hard disk local to the viewer or in a shared location, or on a live buffered feed of video. A second capability of this apparatus and method relates to the use of a plurality of panoramic video or images from multiple synchronized cameras. In those cases, all panoramic video feeds are synchronized so that as a viewer pauses, rewinds, forwards a video in one panorama, all panoramas are time synchronized and go through the same states as the panorama being viewed. When the user selects a different panorama for viewing from a different camera, this panorama comes up in the same state as the panorama previously being viewed.
