Progressive Rotational View Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with slow internet connections or data-limited devices face challenges in viewing 360° rotational views of objects due to high bandwidth requirements, as existing methods often necessitate downloading substantial movie files, leading to prolonged wait times and inefficient bandwidth usage.
Innovation Solution
The technique involves receiving and displaying images in both a gallery view and a rotational view, reusing key images to minimize bandwidth consumption, and allowing the rotational view to be constructed from multiple images, enabling users to manipulate and view perspectives without intermediate frames, thus reducing bandwidth usage and allowing full-quality image viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 360° rotational view is provided using movie format, then complete rotational viewing capability is achieved, but bandwidth consumption increases and viewing time is prolonged
Solution Approach 1:
The patent divides the 360° rotational view into discrete image segments (key images at specific angles and supplementary images filling gaps). Instead of transmitting a continuous movie, only these segmented images are sent, reducing bandwidth while maintaining rotational viewing capability through progressive assembly of the view.
Solution Approach 2:
The system pre-identifies and transmits key images at predetermined angles (0°, 45°, 90°, etc.) before the user needs to view those specific perspectives. This allows the rotational view to be constructed progressively as images are received, enabling users to view objects while waiting for complete image sets without requiring full movie downloads.
2Adaptability or versatility
If 360° rotational view is provided using movie format, then complete rotational viewing capability is achieved, but viewing time is prolonged due to substantial download requirements
Solution Approach 1:
Key images at critical angles are transmitted and made available in advance before the user needs to view those perspectives. The system can begin displaying available images immediately while continuing to receive supplementary images, eliminating the need to wait for complete movie downloads before viewing begins.
Solution Approach 2:
The system dynamically adapts the viewing experience based on image availability. When key images are received, the rotational view is made available immediately. As supplementary images continue to load, the view is progressively enhanced. This dynamic approach allows viewing to start early and improve over time rather than requiring complete data transfer first.
3Adaptability or versatility
If separate images and movies are received for gallery view and rotational view, then complete viewing functionality is achieved, but bandwidth consumption increases
Solution Approach 1:
The key images serve dual purposes: they form the basis of both the gallery view (displaying individual images) and the rotational view (assembling images into a 360° perspective). By reusing these same key images for both viewing modes, the system eliminates redundant data transmission and achieves multi-functionality without increasing bandwidth consumption.
Solution Approach 2:
The patent merges the gallery view and rotational view into a unified image set structure. The same collection of key and supplementary images is used for both purposes, with the system intelligently presenting them in different configurations. This merging approach consolidates data requirements rather than duplicating them, reducing overall bandwidth needs.
4Ease of manufacture
If rotational view uses intermediate frames generated by inbetweening, then smooth rotation appearance is achieved, but data quality is reduced and user cannot access specific perspectives
Solution Approach 1:
Instead of generating synthetic intermediate frames through inbetweening, the system uses actual captured images at multiple angles as the basis for the rotational view. These real images are displayed in their original quality without synthesis, preserving full image data and allowing users to access any specific perspective directly without degradation.

AI summary
Systems and methods for receiving and displaying images or sending the images for display include images having multiple key images of an object. Each key image depicts a perspective view of an item from a different angle around the object. The multiple key images are displayed in a gallery view. During the gallery view, multiple supplementary images are received or sent. Each supplementary image includes a perspective view of the object from an angle between adjacent angles used for the key images. After transmission of at least some of the supplementary images, the key images and the supplementary images are mixed into a rotational view of the object.
