Contextual Information Transmission During Video Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video calls on mobile devices often suffer from blurry video due to limited bandwidth, which is inadequate for scenarios requiring detailed examination, such as video-assisted shopping or lecture attendance, as they typically sacrifice resolution for frame rate.
Innovation Solution
The technology allows for the transmission of contextual information, such as high-resolution still images or depth data, during video calls, enabling users to control resolution and frame rate based on user settings or network conditions, and displaying this information alongside or instead of the default video stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If video calls transmit video streams with higher frame rates, then the smoothness and real-time interaction quality improve, but the resolution decreases resulting in blurry video
Solution Approach 1:
The patent segments the video transmission into two distinct components: a low-resolution high-frame-rate video stream for real-time interaction, and a separate high-resolution contextual information stream (still images) for detailed examination. This segmentation allows each stream to be optimized independently for its specific purpose without compromising the other.
Solution Approach 2:
The patent adds a new dimension to video communication by transmitting contextual information (still images) as a separate data stream alongside the video stream. This dimensional addition enables viewers to access high-resolution details without requiring the main video stream to increase its resolution, thereby maintaining frame rate performance.
2Manufacturing precision
If video calls transmit higher resolution video, then the clarity and detail improve, but the bandwidth consumption increases beyond available network capacity
Solution Approach 1:
The patent extracts the high-resolution detail information from the continuous video stream and transmits it as separate contextual information (still images). This extraction allows the main video stream to maintain lower resolution and thus lower bandwidth consumption, while the extracted high-resolution images are transmitted on-demand or periodically when detailed examination is needed.
Solution Approach 2:
The patent implements periodic transmission of contextual information (still images) at selected moments during the video call, rather than continuously transmitting high-resolution video. This periodic action reduces overall bandwidth consumption compared to continuous high-resolution video transmission, while still providing high-resolution details when needed.
3Adaptability or versatility
If video calls use mobile devices with motion, then the portability and accessibility improve, but the video stability and quality deteriorate
Solution Approach 1:
The patent creates a stable copy of the scene by capturing still images (contextual information) that freeze the moment in high resolution, eliminating the blurriness caused by motion. These still image copies provide stable, motion-free reference views that can be examined in detail regardless of device movement during the video call.
Data Source
AI summary
Aspects of the subject disclosure are directed towards providing contextual information (such as high resolution still images) during an audio or video call. A receiver of the contextual information may send commands to the sending device to specify a desired resolution and frame rate of such images. A receiving user also may determine how to display any video call frames and/or the contextual information on one or more display devices available to the receiving user. Other contextual information such as location-related data by which a user can determine and display a location of the other call participant (or participants) may be transmitted during the call.
