Video Feed Synchronization via Predictive Drive Signal Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to synchronize the actuation of electronic devices with live video feeds due to the time lag in analyzing actions, generating drive signals, and communicating them to the devices.
Innovation Solution
The electronic device control system predicts future actions in a live video feed by generating an action model, which is used to synchronize the actuation of electronic devices with the predicted actions, overcoming the time lag issue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If action analysis and drive signal generation are performed in real-time for live video feeds, then synchronization between electronic device actuation and video action is attempted, but time lag occurs due to the processing and communication time required
Solution Approach 1:
The system pre-generates multiple candidate drive signals corresponding to potential future actions in the video feed before those actions actually occur. By preparing these drive signals in advance, the system eliminates the time lag associated with real-time analysis and generation, allowing the electronic device to be actuated in precise synchronization with the video action without waiting for post-hoc processing.
2Measurement precision
If real-time analysis of live video feed is performed to generate drive signals, then synchronization is attempted, but the processing speed is insufficient to achieve accurate synchronization
Solution Approach 1:
The system performs video frame analysis and drive signal generation in advance, before the corresponding video actions occur. By preprocessing the video feed and generating candidate drive signals ahead of time, the system transforms a real-time processing task into a precomputation task, thereby achieving both high processing speed and accurate synchronization without the constraints of real-time computation.

AI summary
A system and method for generating a drive signal for an electronic device provides a drive signal that causes the electronic device to be actuated in synchronization with action in a video feed. A drive signal generator predicts actions that are likely to occur next in the video feed based on an action model for the video feed and based on information about action that recently occurred in the video feed. The predicted future actions are then used to generate the drive signal that is used to actuate the electronic device.
