Reception Terminal Event Display Control for Shared Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When sharing content data between multiple terminals, there is a need to notify other users of operations performed on one terminal without directly reflecting private user interactions, ensuring that users can view content data privately while still being aware of others' actions.
Innovation Solution
A reception terminal with a display control section that acquires event identification information from a server regarding operations on a transmission terminal and adds associated displays to the content data, allowing users to view and reference the operations performed by others without direct reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If event information from one terminal is directly reflected on another terminal, then collaboration and awareness of others' operations are improved, but user privacy and freedom of private operation are compromised
Solution Approach 1:
The patent segments event information into different types: operational events that are shared with other terminals and private events that remain local. The reception terminal selectively processes only shared events from the transmission terminal, while maintaining independence for private operations. This segmentation allows collaboration on shared content while preserving user privacy and operational freedom.
2Reliability
If content data is shared between multiple terminals, then collaborative viewing is improved, but the ability to perform private operations without affecting others is reduced
Solution Approach 1:
The patent applies local quality by allowing different operational modes on different terminals simultaneously. The transmission terminal operates in a mode where events are broadcast to others, while the reception terminal operates in a mode where it can choose to display or ignore received events based on user preferences. This enables each terminal to have customized operational characteristics suited to its usage context.
3Loss of information
If events from transmission terminal are notified to reception terminal, then user awareness of others' actions is improved, but system complexity increases
Solution Approach 1:
The patent introduces an event management system that acts as an intermediary between transmission and reception terminals. This system receives events from the transmission terminal, filters and processes them according to predefined rules, and selectively notifies the reception terminal. The intermediary layer simplifies the overall system by centralizing the complexity of event management rather than requiring complex peer-to-peer communication logic in each terminal.

AI summary
There is provided a reception terminal including a display control section which performs control of displaying content data shared with a transmission terminal, and an acquisition section which acquires, from a server, event identification information for identifying an event occurred in the transmission terminal regarding the content data, wherein the display control section adds a display associated with the event identification information acquired by the acquisition section to the content data.
