Preview Image Frequency Management for Video Signal Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In systems where multiple computers project video signals, the network load increases due to preview display, leading to inefficiencies in communication and real-time image updates.
Innovation Solution
An information processing device that differentiates between first and second preview images, acquiring and displaying them at varying frequencies to manage communication load, with the second preview image having a larger display area and being updated more frequently than the first, and includes a command unit to optimize update frequencies and terminals for reduced load and enhanced real-time properties.

Engineering Contradiction Analysis
1Ease of operation
If preview display of video signals from multiple computers is implemented, then real-time image updates and user operability are improved, but network load increases
Solution Approach 1:
The patent segments the preview display into two types: first preview images displayed at lower frequency and second preview images displayed at higher frequency. This segmentation allows the system to maintain real-time updates for critical displays while reducing overall network load by not all displays requiring high-frequency updates.
Solution Approach 2:
Different display areas are assigned different update frequencies based on their importance and usage patterns. The system applies local quality by making the update frequency property variable across different preview display areas, allowing critical areas to update more frequently while less critical areas update less frequently.
2Device complexity
If uniform update frequency is applied to all preview images, then implementation simplicity is maintained, but communication load cannot be optimized
Solution Approach 1:
The system transitions from a static uniform update frequency to a dynamic variable update frequency model. The update frequency is no longer fixed but can be adjusted based on display area characteristics, terminal information, and operational context, enabling optimization of communication load while maintaining manageable implementation through automated frequency determination.

AI summary
An information processing device includes: a communication unit which communicates with a plurality of terminals, each outputting a video signal; a first acquisition unit which acquires a first preview image from at least a part of the plurality of terminals; a second acquisition unit which acquires a second preview image having a larger display area size than the first preview image, from a designated terminal of the plurality of terminals; and a display control unit which causes a display unit to display the first preview image and the second preview image on a single screen. A frequency at which the second acquisition unit acquires the second preview image is higher than a frequency at which the first acquisition unit acquires the first preview image.
