Dynamic Image Provisioning for Multi-Device Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multiple angle IPTV services restrict viewers to viewing pre-edited videos within a TV screen, limiting their ability to select and view desired content beyond the fixed screen angles provided by broadcasting stations.
Innovation Solution
A method and apparatus that recognize the relative positions of multiple devices using position information, such as gyro, acceleration, and terrestrial magnetism sensors, to provide partial images or videos corresponding to the device's position, allowing users to select and view specific angles or perspectives on multiple devices seamlessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional broadcasting uses fixed TV screen editing, then the broadcasting station can control the content delivery, but viewers cannot view videos outside the TV screen
Solution Approach 1:
The patent implements dynamic image provision where the system continuously receives position information from multiple devices and dynamically selects and provides different partial images based on real-time device positions. This transforms the static fixed-angle broadcasting into a dynamic system that adapts to viewer positions, enabling viewers to see different angles by moving their devices without manual intervention.
Solution Approach 2:
The system automatically detects device positions using sensors (gyro, acceleration, terrestrial magnetism) and autonomously selects and provides appropriate partial images without requiring viewer input. The broadcasting station's server performs automatic image segmentation, selection, and delivery based on received position data, making the service self-adjusting and eliminating the need for manual viewer control.
2Area of stationary object
If multiple angle service provides pre-edited videos, then the content can be delivered efficiently, but viewers are restricted to within TV screen boundaries
Solution Approach 1:
The patent divides the complete video content into multiple partial images corresponding to different spatial regions or angles. The server segments the original video feed into distinct portions that can be independently selected and delivered to devices based on their positions, effectively expanding the viewing area beyond a single fixed frame while managing complexity through systematic division of content.
Solution Approach 2:
Different devices receive different partial images tailored to their specific positions and orientations. The system provides localized content delivery where each viewer gets a customized view appropriate to their location, maximizing the effective viewing area for each device while the overall system manages complexity through position-based content routing.
3Adaptability or versatility
If the system provides different partial images to multiple devices based on position, then viewer selectivity increases, but the system complexity increases
Solution Approach 1:
The patent introduces a central server as an intermediary that receives position information from multiple devices, processes this data, and coordinates the delivery of appropriate partial images. This intermediary architecture simplifies the overall system by centralizing the complex position recognition and image selection logic in one location, while individual devices remain relatively simple clients that only need to send position data and receive image streams.
Solution Approach 2:
The system replaces complex mechanical or manual position detection mechanisms with electronic sensor-based position information transmission. Devices use built-in sensors (gyroscopes, accelerometers, magnetometers) to automatically determine their position and orientation, substituting sophisticated mechanical position recognition with straightforward electronic sensing and digital communication, thereby reducing system complexity.

AI summary
An method for providing an image to a multiple number of devices is disclosed. The method includes providing a part of the image to a first device, receiving, from a second device, second position information of the second device relative to first position information of the first device, and providing, to the second device, another part of the image corresponding to the position information of the second device.
