Camera System Connection Setting via Delay-Based Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems require cumbersome manual settings and are prone to errors when connecting camera head units (CHUs) to camera control units (CCUs) via asynchronous communication networks, leading to potential system malfunction due to incorrect settings or human errors.
Innovation Solution
A connection setting method that measures image data delay and determines transmission rates for CHUs connected to CCUs over a single transmission network, prioritizing higher priority data to ensure optimal transmission rates within the network's maximum capacity, using dongles to store IP addresses and transmission settings.

Engineering Contradiction Analysis
1Ease of operation
If manual IP address setting is performed for each CHU and CCU, then connection settings can be customized, but the operation becomes cumbersome and error-prone
Solution Approach 1:
The system performs automatic IP address assignment and connection setting without requiring manual user input. The CHU and CCU automatically negotiate and configure their connection parameters, eliminating manual configuration steps and reducing human error.
Solution Approach 2:
The system measures actual transmission delay and uses this feedback to automatically adjust transmission rates. The delay measurement result feeds back to the transmission rate determination process, enabling adaptive optimization without manual intervention.
2Productivity
If multiple image data sets are transmitted over a single network, then network resource utilization improves, but transmission delay increases
Solution Approach 1:
The system dynamically changes transmission rate parameters based on measured delay values. When delay exceeds thresholds, the system adjusts transmission rates of different image data sets to optimize both network utilization and timing performance.
Solution Approach 2:
Different image data sets are assigned different transmission rates based on their specific requirements and priority levels. High-priority data receives higher transmission rates while low-priority data uses lower rates, optimizing overall system performance.
3Speed
If higher transmission rates are used for all image data, then transmission speed improves, but network overload occurs causing timing issues
Solution Approach 1:
The system dynamically adjusts transmission rate parameters based on network conditions and delay measurements. Transmission rates are changed adaptively to maintain optimal speed without causing network overload.
Solution Approach 2:
Instead of uniformly applying high transmission rates to all data, the system applies higher rates only to necessary data streams while using lower rates for others, preventing network overload while maintaining adequate transmission speed for critical data.

AI summary
A connection setting method, used in a camera system in which at least one camera head unit is connected to at least one camera control unit that controls the camera head unit via a single transmission network in order to connect the camera control unit includes: measuring delay of image data from the camera head unit to be connected; and determining a transmission rate at which image data is transmitted from the camera head unit to be connected. The determining is so carried out that when the delay is greater than a threshold corresponding to the amount of data smaller than or equal to a maximum amount of transmission over the network, the sum of the transmission rates at which image data transmitted over the network is smaller than or equal to the maximum amount of transmission over the network and image data having a higher preset priority is transmitted at a higher transmission rate.
