Adaptive Sub-picture Layout for Mobile Video Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conference technologies on mobile terminals require user participation for picture rotation and fail to adjust the layout of sub-pictures during multipoint video conferences, leading to poor display on small screens with multiple participants.
Innovation Solution
A self-adaptive display method and device that determines and adjusts the number of sub-pictures displayed on a mobile terminal based on its placement state, using a multipoint control terminal to select and send the appropriate sub-pictures for display, enhancing user experience by dynamically adjusting the layout and content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the entire image is regarded as the processing unit during picture rotation, then the picture rotation function is simple to implement, but it is unable to adjust the layout of each subpicture in the multi-pictures
Solution Approach 1:
The patent segments the entire picture into multiple subpictures, each of which can be independently processed and positioned. This allows the system to adjust the layout of individual subpictures within the multi-picture display, rather than treating the entire image as a single unit. The segmentation enables flexible arrangement of video feeds from different participants while maintaining overall display coherence.
2Quantity of substance
If more sub-pictures are displayed on the mobile terminal, then more participants can be viewed, but the display screen cannot display clearly the contents of various pictures due to limited screen area
Solution Approach 1:
The patent implements dynamic adjustment of the number of displayed sub-pictures based on the mobile terminal's placement state (portrait or landscape mode). When the terminal is in portrait mode, fewer sub-pictures are displayed to maintain clarity, while in landscape mode, more sub-pictures can be displayed. The system dynamically determines the optimal number of sub-pictures to balance quantity and display quality according to the current orientation and screen dimensions.
3Ease of operation
If the picture rotation request sent by the terminal requires user participation, then the rotation can be controlled by the user, but it is not self-adaptive to the terminal's placement state
Solution Approach 1:
The patent enables the system to automatically detect the mobile terminal's placement state and autonomously determine the appropriate number and arrangement of sub-pictures without requiring user intervention. The system self-adjusts the display configuration based on whether the terminal is in portrait or landscape mode, making the picture rotation and layout adjustment fully automated and self-adaptive to the terminal's current state.
