Solution Overview
Problem
Conventional display devices face challenges in providing camera services without platform changes and restrictions on storage space, and they struggle with bidirectional communication and user-inconvenient network settings when external cameras are installed.
Innovation Solution
A display device configuration that includes a network interface for wireless communication with cameras, an external device interface using HDMI-CEC for bidirectional communication, and a controller to manage camera services, allowing for automatic network setting and seamless integration of camera apps without requiring user-selected connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera service is provided on a conventional TV platform, then camera functionality is added, but the platform requires significant changes and storage space restrictions
Solution Approach 1:
The patent introduces an external camera device as an intermediary that provides camera functionality without modifying the TV's core platform. The camera device communicates with the TV through standardized interfaces (HDMI-CEC, wireless), allowing camera services to be added to the existing platform without requiring platform changes or additional storage space on the TV itself.
2Adaptability or versatility
If an external camera is installed on a TV product, then camera functionality is achieved, but bidirectional communication and development are difficult
Solution Approach 1:
The patent implements a universal communication interface that enables bidirectional communication between the TV and external camera devices. The system supports multiple communication protocols (HDMI-CEC for wired, wireless for wireless cameras), allowing the same TV platform to communicate with various camera types seamlessly, thereby improving ease of operation and development.
3Adaptability or versatility
If camera services are provided through app installation, then functionality is expanded, but storage space is consumed and upgrades are required
Solution Approach 1:
The patent extracts camera service functionality from the TV's internal storage and platform. Instead of installing camera apps on the TV, the system uses external camera devices that communicate with the TV through standardized interfaces. This extraction eliminates the need for storage space consumption on the TV and avoids the need for platform upgrades when new camera services are introduced.
4Adaptability or versatility
If wireless connection requires user selection, then connection flexibility is provided, but user convenience is reduced
Solution Approach 1:
The patent implements preliminary action by automatically establishing wireless connections between the TV and camera devices. Instead of requiring users to manually select and configure connections, the system pre-configures connection parameters and automatically pairs devices when they come into range, thereby maintaining connection flexibility while significantly improving user convenience.
