Dual-Channel Camera Accessory Links for Ordered P2P Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems face inefficiencies in communication with multiple accessory apparatuses, particularly when switching between broadcast and P2P communication methods, leading to longer communication times and the need to restrict or reduce communication frequency to ensure timely communication with specific accessory apparatuses.
Innovation Solution
The implementation of a camera and accessory apparatus system that utilizes a notification channel for notification and a data communication channel for simultaneous and individual communication with multiple accessory apparatuses, enabling efficient data communication through broadcast, party specified, and time-division communication methods, allowing for seamless switching between communication parties in a predetermined order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If P2P communication is performed with a specific accessory apparatus, then communication speed is improved, but communication time increases due to the need for party specification and method switching
Solution Approach 1:
The notification channel is activated in advance to notify accessory apparatuses of upcoming data communication. This preliminary notification allows the system to prepare for P2P communication without requiring time-consuming party specification and method switching during the actual data transfer, thus resolving the contradiction between communication speed and communication time.
2Productivity
If communication with multiple accessory apparatuses is performed simultaneously, then productivity is improved, but communication control complexity increases
Solution Approach 1:
The communication system is segmented into two distinct channels: a notification channel for broadcasting communication requests and a data communication channel for actual data transfer. This segmentation allows simultaneous communication with multiple accessory apparatuses while simplifying control, as the notification channel handles the complexity of multi-device coordination while the data channel focuses solely on efficient data transfer.

AI summary
A camera is operable while a plurality of accessory apparatuses are connected to the camera. The camera is configured to control communication with the plurality of accessory apparatuses using a notification channel for notification with the plurality of accessory apparatuses and a data communication channel for data communication with the plurality of accessory apparatuses. The camera is configured to perform first communication for simultaneous communication with the plurality of accessory apparatuses using the data communication channel, and second communication for individual communication with a specific accessory apparatus among the plurality of accessory apparatuses using the data communication channel. The camera is configured to perform the second communication by switching between specific accessory apparatuses in a predetermined order.
