Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Internet TV environments lack the ability to adjust system settings for externally connected display monitors or projectors, requiring significant resources in terms of manpower and financial investment to develop applications with system setting functions.
Innovation Solution
A projection system comprising an image control device and a projector, where the image control device includes a processing module, an application, and a communication port, and the projector also has a processing module and a communication port, allowing for the transmission of control signals between the two devices through interfaces such as TTYS or USB, enabling the projector to execute functions corresponding to the control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If basic playback operation functions are provided in Internet TV environment, then the system is simple and easy to operate, but the ability to adjust system settings for externally connected display monitors or projectors is lost
Solution Approach 1:
The patent introduces a mediator device that acts as an intermediary between the Internet TV and the projector. This mediator receives control signals from the Internet TV, processes them, and sends appropriate commands to the projector. This allows the Internet TV to control projector settings without needing direct integration, thus maintaining simplicity while adding versatility.
Solution Approach 2:
The control system is segmented into separate functional modules: the Internet TV handles media playback, the mediator handles signal processing and protocol conversion, and the projector handles display output. This segmentation allows each component to remain simple while the overall system achieves advanced functionality through coordinated operation of the segments.
2Adaptability or versatility
If applications with system setting functions are developed for Internet TV, then the adaptability to control projector settings is improved, but the resource investment in terms of manpower and financial cost increases substantially
Solution Approach 1:
The mediator device is designed with universal functionality to work with multiple types of projectors and Internet TV systems. It implements a standardized interface that can handle various control protocols, making it a multi-functional component that doesn't require custom development for each specific device combination, thereby reducing overall system complexity.
Solution Approach 2:
Instead of developing custom applications for each Internet TV system, the patent uses a standardized mediator that copies and adapts control signals according to predefined protocols. This approach avoids the need to recreate control functionality for each platform, significantly reducing development resources while maintaining adaptability.
3Productivity
If direct communication between Internet TV and projector is established, then the control signal transmission is efficient, but the system complexity and security permission requirements increase
Solution Approach 1:
The mediator serves as an efficient communication bridge that maintains direct signal transmission while managing the complexity of direct integration. It handles protocol conversion and signal processing in real-time, ensuring efficient communication without requiring complex peer-to-peer integration between the Internet TV and projector.

AI summary
A projection system and a control method are provided. The projection system includes an image control device and a projector. The image control device stores an application and includes a first communication port. The image control device is configured to execute the application to generate a control signal. The first communication port includes at least one of a teletype serial (TTYS) interface and a universal serial bus (USB) interface. The image control device is configured to transmit the control signal to a second communication port of the projector through the first communication port, so that the projector executes a function corresponding to the control signal.
