Wireless Camera-Microphone Sync for Recording Start Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face issues with coordination between image capturing devices and microphones, leading to potential discrepancies in recording timings and loss of synchronized audio-visual data during operations like police patrols.
Innovation Solution
An image capturing apparatus and a microphone apparatus are designed for wireless communication, enabling synchronized video and voice recording through coordinated control units and transmission of video recording start signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera and microphone operate independently with separate recording controls, then each device can function autonomously, but the recording timings may deviate and audio-visual synchronization is lost
Solution Approach 1:
The patent introduces a camera operation notification unit that acts as an intermediary between the camera and microphone. When the camera starts recording, it sends a notification signal to the microphone, which then automatically starts voice recording. This mediator mechanism ensures synchronized recording without requiring complex bidirectional coordination protocols between both devices.
2Measurement precision
If the system uses manual coordination between camera and microphone operations, then device complexity is reduced, but recording synchronization accuracy deteriorates
Solution Approach 1:
The microphone apparatus is designed to autonomously respond to camera operation notifications. Upon receiving a recording start notification from the camera, the microphone automatically initiates voice recording without requiring manual intervention or complex coordination algorithms. This self-service approach achieves precise synchronization while keeping the control mechanism simple.
3Reliability
If the camera transmits video recording instructions to the microphone, then recording coordination is improved, but wireless communication complexity increases
Solution Approach 1:
The patent extracts the coordination function from a complex bidirectional communication system and simplifies it to a unidirectional notification mechanism. The camera's operation notification unit sends simple start/stop signals to the microphone, eliminating the need for complex acknowledgment protocols, error handling, and双向 synchronization algorithms.
