Video Conference System Combining Multiple Video Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conference systems for wireless presentation do not effectively combine video data from multiple presenters, leading to interruptions and an inability to capture and display presenter facial expressions, making remote participation less engaging and complicating the identification of speakers in recorded sessions.
Innovation Solution
A video conference system that combines video data from multiple sources, including presentation file content, presenter facial video, and user input data, such as mouse cursor trails, into a single combined video stream for transmission to both near-end and far-end display devices, enhancing remote participation and recording clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data from multiple presenters is transmitted through unplugging/plugging video signal lines between different computers, then the video conference can switch between presenters, but the video wire is damaged easily and the conference is interrupted
Solution Approach 1:
The patent combines multiple video inputs (presentation content from computer and presenter facial video from camera) into a single integrated video stream. The transmitter device merges these sources and transmits them together through one wireless connection, eliminating the need to repeatedly connect and disconnect video cables between different computers, thus improving reliability and operational convenience
2Adaptability or versatility
If only presentation content is transmitted to far end display devices, then the transmission is simple, but remote participants cannot see presenter facial expressions reducing engagement
Solution Approach 1:
The transmitter device merges presentation content video data with presenter facial video data from a camera into a single combined video stream. This integration allows far-end participants to simultaneously view both the presentation content and the presenter's facial expressions, enhancing engagement without requiring separate transmission channels
Solution Approach 2:
The transmitter device performs multiple functions: it captures presentation content from the computer video output, simultaneously captures presenter facial video from the camera, combines these streams, and transmits the integrated result. This multi-functional approach ensures complete video content transmission while managing complexity within a single device
3Loss of information
If presentation content and presenter facial video are transmitted separately, then the transmission channels are simple, but the recording cannot identify which presenter is speaking
Solution Approach 1:
The transmitter device combines presentation content video and presenter facial video into a single integrated stream where temporal correspondence is maintained. This merging ensures that when the combined video is recorded and reviewed, the association between the presenter's face and the presentation content remains intact, enabling accurate speaker identification without requiring separate channel management
Data Source
AI summary
A video conference system including a transmitter device and a receiver device is provided. The transmitter device includes a transmitter control unit, a transmitter input interface, a transmitter video circuit and a first wireless transmission module. The transmitter control unit is coupled to a video output port of an information system and receive a first video data from the video output port. The transmitter input interface receives a second video data from a first video source. The transmitter video circuit combines the first video data and the second video data as a combined video data. The first wireless transmission module transmits the combined video data to the receiver device. The receiver device, coupled to the display device, includes a second wireless transmission module, which receives the combined video data. The receiver device transmits the combined video data to the display device.
