Video Conference Layout Distribution for Terminal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing systems face issues with inconsistent video data sizes from different terminals, leading to poor display effects due to varying parameters like aspect ratio and resolution, and increased operational burden on the conference apparatus from processing video data.
Innovation Solution
The method involves acquiring and sending layout information of conference pictures to terminals, allowing them to process their video data to match the layout specifications, reducing the burden on the conference apparatus by having terminals individually adjust their video data based on received information, and combining these into conference video data with consistent sizes for better display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conference apparatus processes video data from multiple terminals, then the video conference can be conducted, but the operational burden on the conference apparatus increases
Solution Approach 1:
The video processing task is segmented between terminals and the conference apparatus. Terminals perform local video processing to generate standardized video data, while the conference apparatus only performs lightweight synthesis and distribution. This division reduces the operational burden on the conference apparatus while maintaining video conference functionality.
Solution Approach 2:
Terminals perform video processing in advance before transmitting to the conference apparatus. The video data is pre-processed to match the conference picture layout requirements, including scaling, cropping, and formatting operations. This preliminary action eliminates the need for heavy processing at the conference apparatus.
2Manufacturing precision
If video data from different terminals is combined without layout information, then the video conference can proceed quickly, but the display effect deteriorates due to inconsistent sizes
Solution Approach 1:
Layout information is acquired and distributed to terminals in advance before video data transmission. Terminals use this pre-provided layout information to process their video data accordingly, ensuring size consistency without requiring iterative adjustment or post-processing at the conference apparatus.
Solution Approach 2:
Terminals change video data parameters (resolution, aspect ratio, cropping coordinates) based on the received layout information. This parameter adjustment ensures that all video data conforms to the required size specifications for the conference picture, achieving consistent display quality.
3Manufacturing precision
If the conference apparatus processes all video data centrally, then display consistency is improved, but the system complexity increases
Solution Approach 1:
The video processing system is segmented into terminal-based processing units and a central coordination unit. Each terminal independently processes its own video data according to layout specifications, eliminating the need for complex centralized processing while maintaining display consistency across all participants.
Solution Approach 2:
Terminals perform self-service video processing using the layout information provided by the conference apparatus. Each terminal autonomously adjusts its video data parameters without requiring complex coordination or processing from the conference apparatus, simplifying the overall system architecture.
