High-Resolution Video Conferencing Data Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During audio/visual conferencing, participants can only receive low-resolution images of other participants, limiting the quality of captured images and preventing high-resolution image capture from the transmitting party.
Innovation Solution
A method to generate and transmit high-resolution audio/video streams during conferencing, allowing participants to request and receive high-resolution images or video streams from other devices, either directly or through alternative communication channels, enabling high-quality image capture and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video streams are transmitted during conferencing, then real-time communication is enabled, but image resolution is reduced to low-quality
Solution Approach 1:
The patent segments the video transmission process into two distinct phases: real-time low-resolution transmission for immediate communication, and post-conference high-resolution transmission for quality capture. This segmentation allows both real-time functionality and high-quality imaging to coexist without interfering with each other.
Solution Approach 2:
The system performs preliminary action by capturing and storing high-resolution video data locally on each participant's device during the conference, even though this data is not transmitted in real-time. This preliminary capture ensures that high-quality images are available for later retrieval and transmission without compromising real-time performance.
2Manufacturing precision
If high-resolution images are transmitted during conferencing, then image quality is improved, but network bandwidth and system resources are overwhelmed
Solution Approach 1:
The patent extracts the high-resolution image transmission function from the real-time conferencing process. Instead of attempting to transmit high-resolution images during the live conference, the system extracts this function to occur separately after the conference ends, thereby avoiding the resource conflicts that would arise from simultaneous high-bandwidth transmission.
Solution Approach 2:
High-resolution video data is preliminarily captured and stored locally on each participant's device during the conference. This preliminary local storage eliminates the need for real-time high-bandwidth transmission, reducing network and system resource requirements while preserving image quality for later use.
3Ease of manufacture
If only low-resolution images are available from screen capture, then system resources are conserved, but image quality and detail are insufficient
Solution Approach 1:
The patent segments the image quality requirements into two scenarios: low-resolution images suffice for real-time viewing during the conference (conserving resources), while high-resolution images are provided on-demand after the conference (satisfying quality requirements). This segmentation allows the system to be resource-efficient while still delivering high quality when needed.
Solution Approach 2:
Instead of transmitting high-resolution video data in real-time, the system creates a copy of the high-resolution video stream locally on each participant's device. This local copy can be retrieved and transmitted after the conference without impacting real-time resource usage, effectively decoupling resource consumption from image quality delivery.
Data Source
AI summary
A first request to form a conference call is received from a first of a plurality of electronic devices. In response to the first request, a conference data structure is generated in a memory. Based on determining the conference call has ended, a second request is transmitted to each of the plurality of electronic devices to return a high-resolution video stream generated by each electronic device during the conference call. In response to the second requests, the high-resolution video stream is received from at least some of the plurality of electronic devices. Each of the received high-resolution video streams is stored in the conference data structure in the memory to generate a completed conference data structure. A notice that the completed conference data structure is available is transmitted to each of the plurality of electronic devices.
