Video Signal Text Data Insertion for Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video recording systems lack the ability to attach human-readable information to video materials in response to operations performed on cameras or downstream apparatuses, and they face interoperability issues with systems not complying with specific control information standards.
Innovation Solution
A video signal generating apparatus that includes a camera, an operating device, a text data generating device, and a text data inserting device to generate and insert human-readable text data into the video signal, allowing downstream apparatuses to interpret and perform operations based on the attached text data, ensuring interoperability with other systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If text data is inserted into the video signal to enable downstream apparatuses to perform operations, then the functionality and interoperability of the system is improved, but the device complexity increases due to the need for text data generating and inserting devices
Solution Approach 1:
The text data generating device and text data inserting device are integrated into the video signal generating apparatus, combining multiple functions (camera operation control and metadata insertion) into a single unified system. This reduces the need for separate external devices while maintaining the capability to generate and insert operational text data into the video signal for downstream apparatus control.
Solution Approach 2:
The video signal generating apparatus is designed to perform multiple functions: capturing video signals through the camera, generating text data based on camera operations, and inserting this text data into the video signal stream. This multi-functional approach allows a single apparatus to serve both as a video source and a control information source, improving interoperability without requiring additional specialized devices.
2Productivity
If human-readable text data is attached to video materials to enable high-speed access and operations, then the productivity of video processing is improved, but the loss of information increases due to the additional data processing requirements
Solution Approach 1:
Text data containing operational information is generated and inserted into the video signal in advance, during the video capture process itself. This preliminary attachment of control information allows downstream apparatuses to immediately interpret and act on the data without requiring separate metadata files or post-processing steps, enabling high-speed access and operations while maintaining data integrity.
