Split Video Streaming for Local High-Res and Remote Low-Res Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote conferencing meetings with both local and remote participants, existing technologies often downscale video content for remote participants, resulting in local participants viewing the video at a lower resolution than intended, which diminishes their experience.
Innovation Solution
An apparatus comprising a video splitter, scaler, and encoder that splits an input video stream into two streams: a high-resolution stream for local display and a lower-resolution stream for remote display, ensuring local participants view the content at its intended resolution while remote participants receive a compatible lower-resolution version.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is downscaled for remote participants, then remote participants can receive video content, but local participants cannot view the content at its intended higher resolution
Solution Approach 1:
The video stream is segmented into multiple resolution versions (original high-resolution stream and downscaled low-resolution stream). The system divides the single video source into separate streams with different quality levels, allowing each participant group to receive the appropriate resolution without compromising the other.
Solution Approach 2:
Different quality levels are provided to different participant groups based on their location and needs. Local participants receive the high-resolution original stream for optimal viewing quality, while remote participants receive the downscaled stream optimized for network transmission, ensuring each group gets the most appropriate quality for their context.
2Manufacturing precision
If video content is displayed at high resolution for local participants, then local participants have better viewing experience, but remote participants cannot receive the video content efficiently
Solution Approach 1:
The video stream parameters (resolution, bitrate) are changed to create different versions for different participant groups. The system transforms the original high-resolution stream into a downscaled low-resolution stream with optimized parameters for efficient network transmission to remote participants, while maintaining the original high-resolution stream for local display.
3Device complexity
If a single video stream is used for both local and remote participants, then the system is simple, but the experience for both groups cannot be optimized simultaneously
Solution Approach 1:
The video processing system is segmented into multiple processing paths: one path handles the original high-resolution stream for local display, while another path processes the downscaled stream for remote transmission. This segmentation allows the system to optimize for both participant groups simultaneously while keeping each processing path relatively simple and manageable.

AI summary
According to examples, an apparatus may include a video switch, a video scaler, and a video splitter. The video splitter may access an input video stream, in which the input video stream is at a first resolution, split the accessed input video stream into a first video stream and a second video stream, send the first video stream to be displayed at the first resolution through the video switch, and send the second video stream to the video scaler. The video scaler may scale the second video stream to a second resolution that differs from the first resolution and output the scaled second video stream to be displayed at the second resolution.
