Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video mixing systems face limitations in processing high-definition video signals in real time due to bandwidth and processing constraints, leading to degraded video quality when handling multiple high-bandwidth sources, and lack efficient methods for dynamically adjusting signal parameters to prioritize important sources.
Innovation Solution
An adaptive video mixing system that dynamically regulates video signal parameters, such as compression and encoding, across a network to prioritize high-quality signals and allocate resources based on the importance of each source, using a Mixer Adaptive Controller to manage bandwidth and resources, allowing for real-time adjustments to ensure high-quality output.

Engineering Contradiction Analysis
1Quantity of substance
If multiple high-definition video sources are processed simultaneously, then the quantity of video sources increases, but the video quality degrades due to bandwidth and processing limitations
Solution Approach 1:
The patent applies local quality by assigning different importance levels to different video sources and adjusting their bandwidth allocation accordingly. Critical sources receive higher bandwidth and processing resources, while less important sources receive reduced resources. This allows the system to maintain high video quality for important sources while processing multiple sources simultaneously within bandwidth constraints.
Solution Approach 2:
The system dynamically changes parameters such as bandwidth allocation, resolution, and frame rate for different video sources based on their importance level. The bandwidth allocation module adjusts these parameters in real-time to optimize the balance between the number of sources processed and the quality of each source, resolving the contradiction between quantity and quality.
2Manufacturing precision
If bandwidth is increased to maintain high-quality video signals, then the video quality is preserved, but the system resource consumption increases
Solution Approach 1:
The patent uses parameter changes by dynamically adjusting bandwidth allocation, resolution, and frame rate based on the importance level of each video source. This allows the system to preserve high video quality for critical sources while reducing bandwidth consumption for less important sources, thereby optimizing the trade-off between video quality and resource consumption.
Solution Approach 2:
By applying local quality, the system allocates high bandwidth and processing resources only to video sources that require high quality (critical sources), while using reduced bandwidth for other sources. This targeted approach maintains necessary video quality without unnecessarily consuming system resources across all sources.
3Ease of operation
If all video sources are allocated equal bandwidth, then fairness is maintained, but the overall system efficiency decreases
Solution Approach 1:
The patent implements local quality by differentiating bandwidth allocation based on the importance level of each video source. Instead of equal allocation, the system provides differentiated resource distribution where critical sources receive more bandwidth and less critical sources receive less, thereby improving overall system efficiency while maintaining operational simplicity through automated importance-based classification.

AI summary
An adaptive mixer controller and process for mixing video streams in a networked and non-networked environment that adjusts the bandwidth affecting parameters of the input signals and/or the system in real time in response to the video output of the input signals being mixed, to allow mixing within the demands and constraint of the entire system. The invention calculates the values of selected bandwidth affecting parameters as defined, and modifies selected bandwidth affecting parameters in real time at addressable control devices upstream from the mix and video output, doing so in real time in response to the needs of the mixer requirements for the selected output needs.
