Wide-Angle Playback Viewpoint Synchronization Across Display Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems struggle with efficiently sharing and displaying wide-angle view images across multiple sites, leading to difficulties in synchronizing user viewpoints and effective communication.
Innovation Solution
A communication system and method that includes an information processing system, communication terminals, and display terminals, which enable the sharing and display of wide-angle view images with synchronized viewpoints by transmitting and receiving viewpoint information, allowing users to easily change and view predetermined areas within the image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wide-angle view image is transmitted to multiple sites, then users can view the entire circumference of 360 degrees, but users at different sites cannot synchronize their viewpoints to focus on the same predetermined area
Solution Approach 1:
The patent introduces viewpoint information as an intermediary element that bridges the gap between wide-angle image transmission and synchronized viewing. The communication terminal transmits not only the wide-angle image but also accompanying viewpoint information that specifies the predetermined area of interest. This intermediary viewpoint information allows remote display terminals to accurately reproduce the intended viewing focus, enabling synchronization without requiring complex real-time interaction protocols.
2Adaptability or versatility
If users can individually change desired predetermined areas in the wide-angle view image, then each user can focus on their area of interest, but the system becomes more complex requiring coordination mechanisms
Solution Approach 1:
The patent applies preliminary action by having the communication terminal pre-determine and transmit viewpoint information before the user actually views the image. Instead of requiring real-time coordination where users simultaneously select areas and the system dynamically adjusts, the viewpoint information is prepared in advance and transmitted with the wide-angle image. This allows users to individually select their areas of interest without complex real-time coordination, as the system already has the necessary viewpoint data ready for reproduction at remote sites.
3Ease of operation
If viewpoint information is transmitted along with the wide-angle view image, then users at remote sites can display the same predetermined area, but the data transmission load increases
Solution Approach 1:
The patent extracts only the essential viewpoint information needed for synchronization rather than transmitting complete image data or complex control signals. The viewpoint information contains minimal data elements (such as coordinates or parameters defining the predetermined area) that are sufficient for remote display terminals to reproduce the intended focus. By taking out only this critical synchronization data rather than transmitting full image streams or complex control protocols, the system achieves viewpoint synchronization with minimal additional data transmission overhead.
Data Source
AI summary
A display terminal includes circuitry to receive an operation for displaying a playback of a wide-angle view image related to a moving image recorded at a time of streaming of the moving image. The wide-angle view image has a wide viewing angle. The circuitry displays, on a display, a display area representing a predetermined area of the wide-angle view image based on viewpoint information for specifying the predetermined area, in response to receiving the operation. The predetermined area is displayed by a communication terminal at the time of streaming of the moving image.
