Video Conference Switching During Phone Calls Without Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices with a single camera face challenges in transmitting live video streams due to limited processing resources and network constraints, making it difficult to compose and transmit video from multiple cameras simultaneously.
Innovation Solution
A mobile device equipped with two cameras can transmit live video streams from both cameras simultaneously, allowing for composite displays and dynamic camera switching, along with real-time adjustments and remote control capabilities during video conferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable device transmits live video from multiple cameras simultaneously, then the video conferencing capability is enhanced, but the processing resources and network bandwidth are overwhelmed
Solution Approach 1:
The patent segments the video processing by separating capture, processing, and transmission functions across multiple devices. The portable device captures video from multiple cameras locally, then transmits only the necessary video streams to remote devices, dividing the processing burden across the network rather than concentrating it all in one device.
Solution Approach 2:
The patent enables portable devices to function as both video captors and video transmitters simultaneously. The device can capture video from multiple cameras, process it locally, and transmit selected streams, making it a multi-functional unit that adapts to different video conferencing needs without requiring separate dedicated hardware for each function.
2Productivity
If a portable device with one camera transmits live video, then the device can maintain processing resources, but the video conferencing experience is limited
Solution Approach 1:
The patent implements dynamic camera switching during video conferences. The system can switch between different camera streams based on current conferencing needs, allowing a single camera device to provide varied video perspectives and enhancing the overall video conferencing experience without requiring multiple simultaneous transmissions.
Solution Approach 2:
The patent introduces a video conference server as an intermediary that receives video streams from portable devices and distributes them to participants. This mediator handles the complexity of managing multiple video streams, allowing individual devices with limited capabilities to participate in rich multi-camera conferences through the server's coordination.
3Quantity of substance
If video is uploaded to an Internet hosting site after capture, then storage is achieved, but real-time transmission to another party is not possible
Solution Approach 1:
The patent performs preliminary video processing and encoding on the portable device itself before transmission. By capturing, processing, and preparing video streams locally in advance, the system eliminates the need to upload raw video to external hosting sites, enabling immediate real-time transmission to conference participants without external storage intermediaries.
Data Source
AI summary
Some embodiments provide a method for initiating a video conference using a first mobile device. The method presents, during an audio call through a wireless communication network with a second device, a selectable user-interface (UI) item on the first mobile device for switching from the audio call to the video conference. The method receives a selection of the selectable UI item. The method initiates the video conference without terminating the audio call. The method terminates the audio call before allowing the first and second devices to present audio and video data exchanged through the video conference.
