Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack standards and efficient methods for acquiring, generating, and reproducing panoramic images, especially for displaying them in their original form without distortion on existing DTV receivers.
Innovation Solution
A method involving encoding panoramic images, dividing them into multiple images, and transmitting these images with signaling information that includes panorama composition details, allowing for efficient multiplexing and decoding to maintain image quality and display them on various devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If panoramic images are transmitted as single large images, then image quality is maintained, but transmission bandwidth and device compatibility are problematic
Solution Approach 1:
The panoramic image is divided into multiple sub-images (e.g., left, center, right views) that can be independently transmitted and decoded. This segmentation allows the system to maintain high image quality for each sub-image while adapting to different device screen sizes and formats by selectively displaying appropriate portions.
Solution Approach 2:
The patent introduces signaling information that adds a new dimension to the transmission system, carrying metadata about panorama composition, view types, and display parameters. This additional information layer enables receivers to properly reconstruct and display panoramic content without requiring changes to the core image transmission format.
2Adaptability or versatility
If panoramic images are divided into multiple images for transmission, then device compatibility improves, but image quality and seamless reconstruction become challenging
Solution Approach 1:
The signaling information provides feedback to the receiver about how the panoramic image was composed, including the arrangement of sub-images, their relative positions, and any overlapping regions. This feedback enables the receiver to accurately reconstruct the panoramic view by properly positioning and blending the decoded sub-images.
Solution Approach 2:
The signaling information acts as an intermediary between the transmitted sub-images and the final reconstructed panoramic image. It carries the necessary composition data that mediates the reconstruction process, ensuring that multiple divided images can be seamlessly assembled into a coherent panoramic view.
3Productivity
If signaling information about panorama composition is added to broadcast stream, then panorama service efficiency improves, but data transmission volume increases
Solution Approach 1:
The signaling information is structured to provide localized details only where needed, such as composition data for specific regions or views. This allows the system to transmit minimal necessary information for each sub-image rather than redundant data for the entire panorama, reducing overall data volume while maintaining service efficiency.
