Solution Overview
Problem
Existing communication systems struggle with efficiently sharing and viewing wide-angle view images across multiple sites, leading to difficulties in coordinating virtual viewpoints and effective communication among users.
Innovation Solution
A communication system and method that includes an information processing system, communication terminals, and display terminals, which facilitate the sharing of wide-angle view images and synchronize viewpoint information to ensure consistent viewing of predetermined areas across different sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wide-angle view images are transmitted to multiple sites for remote communication, then users can view images with wide viewing angles and large capturing ranges, but it becomes difficult to coordinate virtual viewpoints and identify which predetermined areas are being viewed at each site
Solution Approach 1:
The system transmits viewpoint information from the communication terminal to the display terminal, creating a feedback loop that enables the display terminal to identify and display the specific predetermined area being viewed. This feedback mechanism resolves the information loss about viewpoint coordination while maintaining wide viewing angle capabilities.
Solution Approach 2:
Viewpoint information acts as an intermediary element between the communication terminal and display terminal, carrying coordination data that enables synchronized viewing of predetermined areas across multiple sites without compromising the wide-angle viewing capability.
2Loss of information
If viewpoint information is transmitted between terminals to coordinate viewing, then users can identify specific predetermined areas being viewed, but the system complexity increases
Solution Approach 1:
The viewpoint information transmission mechanism serves multiple functions: it identifies predetermined areas being viewed, enables synchronized display across terminals, and provides coordination data for remote communication. This multi-functionality reduces overall system complexity by consolidating multiple needs into a single information exchange protocol.
3Duration of action of stationary object
If recorded wide-angle view images are played back at display terminals, then users can review past communication sessions, but the ability to accurately represent and display the original predetermined viewing areas is lost
Solution Approach 1:
Viewpoint information is transmitted and stored in advance during the streaming phase, before playback occurs. This preliminary action ensures that when recorded wide-angle view images are played back, the original predetermined viewing areas can be accurately identified and displayed without loss of viewpoint information.
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.
