Terminal Output Control for Conference Page Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paperless conference systems face challenges in reducing page-turning time and synchronizing page displays across multiple client terminals, leading to inefficiencies in data acquisition and display.
Innovation Solution
The system employs a client terminal with an output control unit that anticipates and caches subsequent page data, allowing for timely display and synchronization by controlling the timing of data acquisition and using a network-connected conference server to manage and distribute page data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If page data is acquired in real-time from the server, then data freshness is maintained, but page-turning time increases and display synchronization becomes difficult
Solution Approach 1:
The terminal device performs preliminary actions by acquiring and caching subsequent page data in advance before it is actually needed for display. The output control unit controls timing to acquire second data (subsequent page data) that will be output later, storing it in the storage unit. This preliminary acquisition eliminates waiting time during page turns while maintaining synchronization through coordinated timing control.
2Productivity
If multiple terminals acquire data simultaneously from the server, then data consistency is maintained, but network load increases and response time decreases
Solution Approach 1:
Terminals perform preliminary data acquisition by caching subsequent page data in advance. This reduces the need for frequent real-time requests to the server, thereby reducing network bandwidth consumption while maintaining fast local display performance.
Solution Approach 2:
The terminal device's storage unit acts as an intermediary cache between the server and the display system. Instead of direct real-time requests for every page turn, the intermediary cache provides locally stored data, reducing server-load and network traffic while maintaining fast access.
3Speed
If cache is used to reduce page-turning time, then display speed improves, but data freshness and synchronization with server may be compromised
Solution Approach 1:
The output control unit implements feedback control by monitoring display timing and coordinating cache acquisition with actual display needs. It controls timing to acquire subsequent page data based on when that data will be needed, ensuring cache data is fresh and synchronized with the server's current state while maintaining fast display performance.
Data Source
AI summary
An information processing system includes one or more terminal devices; and an information processing apparatus connected to the one or more terminal devices via a network. Further, the terminal device includes an output control unit controlling timing to acquire a second data which are to be output subsequent to a first data which are output in response to an instruction from the information processing apparatus, and a storage unit storing the second data acquired by the output control unit.
