Multi-Camera Resolution Sequencing for LAN Streaming Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-angle live streaming using multiple image capturing apparatuses connected to a single LAN, the communication load increases due to simultaneous transmission of high-resolution data, leading to potential delays and processing lags during resolution changes.
Innovation Solution
A control apparatus that dynamically adjusts the transmission data size settings for each image capturing apparatus by changing the resolution of one apparatus to a lower setting before changing the resolution of another, thereby preventing simultaneous high-resolution data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple image capturing apparatuses transmit high-resolution data simultaneously over a single LAN, then the video quality and resolution are improved, but the communication load increases and delays occur
Solution Approach 1:
The patent applies dynamics by making the resolution setting changeable over time based on communication conditions. The control apparatus dynamically adjusts the resolution of image capturing apparatuses from high to low resolution when communication load becomes excessive, allowing the system to adapt to varying network conditions and prevent delays while maintaining high quality when possible
Solution Approach 2:
The patent changes the resolution parameter of the image capturing apparatuses to control communication load. By switching the resolution parameter between high and low settings based on the number of connected apparatuses and network conditions, the system optimizes the balance between video quality and communication efficiency
2Adaptability or versatility
If the resolution is changed dynamically during operation, then the communication load can be adjusted, but a period of time may occur where multiple apparatuses transmit high-resolution data simultaneously
Solution Approach 1:
The control apparatus performs preliminary action by notifying image capturing apparatuses of upcoming resolution changes before actually implementing them. This advance notification allows apparatuses to prepare for the transition, ensuring they switch to low resolution at the appropriate time and preventing periods where multiple apparatuses simultaneously transmit high-resolution data
Solution Approach 2:
The system uses feedback by monitoring the number of connected image capturing apparatuses and communication conditions, then adjusting resolution settings accordingly. The control apparatus receives information about the current state and makes resolution adjustments based on this feedback, ensuring reliable communication load control while maintaining adaptability

AI summary
A control apparatus that controls a plurality of image capturing apparatuses including at least a first image capturing apparatus and a second image capturing apparatus includes a reception unit that receives a change in the setting values for one or more of the plurality of image capturing apparatuses, and a change unit that, upon reception of the received change in the setting values of the plurality of image capturing apparatuses, changes a first setting value of the first image capturing apparatus to a second setting value at which the transmission data size is smaller than the transmission data size at the first setting value, and then changes the setting value of the second image capturing apparatus to a third setting value at which the transmission data size increases, wherein the obtaining unit and the change unit are implemented by one or more processors.
