Video Conference Layout Stability via Static Image Pre-caching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Videoconferencing systems face challenges with frequent changes in network bandwidth, leading to unstable image data reception and layout fluctuations, which can annoy users and disrupt conference experiences.
Innovation Solution
An information processing apparatus with a receiver, video data determiner, static image data storage, and display processor that determines the video data to receive based on network conditions, storing static image data and displaying it in screen areas when the number of received video data is less than the screen areas, maintaining a consistent layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system dynamically adjusts video data reception based on network bandwidth, then the adaptability to network conditions improves, but the layout stability deteriorates due to frequent changes in the number of displayed video streams
Solution Approach 1:
The system pre-acquires static image data from all participating terminals and stores it in advance. When video data reception is interrupted due to network bandwidth limitations, the display processor can immediately switch to displaying the pre-stored static images, avoiding layout fluctuations and providing a smooth transition that maintains layout stability while adapting to network conditions.
2Reliability
If the system prioritizes audio data reception over image data when bandwidth degrades, then the audio quality improves, but the visual information completeness worsens due to reduced number of displayed participants
Solution Approach 1:
The system creates static image copies of all video streams and stores them in advance. When network bandwidth degrades and video reception is interrupted, these static image copies are displayed instead of the live video streams. This allows the system to maintain complete visual information display using the pre-captured images while prioritizing audio data reception, thus preventing loss of visual information without compromising audio quality.

AI summary
An information processing apparatus to display video data on a display apparatus includes a receiver to receive the video data from one or more other information processing apparatuses via a network, a video data determiner to determine the video data to be received by the receiver according to a communications status, a static image data storage to acquire static image data from the one or more other information processing apparatuses to store the acquired static image data, and a display processor to generate a screen having one or more areas to display the video data determined by the video data determiner in the areas. The display processor displays the static image data stored in the static image data storage in the areas when a determined number of the video data is less than a number of the areas.
