Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of proprietary or common cables and connectors for peripheral devices in content processing systems increases costs and introduces additional failure points, necessitating a method to implement peripheral devices without these drawbacks.
Innovation Solution
A system utilizing a high definition multimedia interface (HDMI) for communicating control signals and applications to control units, allowing peripheral devices to be connected and controlled via serial ports, thereby eliminating the need for additional cables and connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary or common cables and connectors are used for peripheral devices, then device connectivity is achieved, but system cost increases and additional failure points are introduced
Solution Approach 1:
The patent combines multiple communication functions (video, audio, data, control signals) into a single HDMI cable connection. The HDMI interface integrates these previously separate connections, eliminating the need for additional proprietary or common cables and connectors for peripheral device control, thereby reducing failure points while maintaining connectivity.
Solution Approach 2:
The HDMI interface is used for multiple purposes: transmitting video, audio, and now peripheral device control signals. This multi-functional use of a single established interface eliminates the need for separate specialized cables and connectors, reducing system complexity and potential failure points while maintaining universal compatibility.
2Ease of operation
If additional cables and connectors are used for peripheral devices, then device connectivity is achieved, but installation cost increases
Solution Approach 1:
The patent merges peripheral device control communication into the existing HDMI cable infrastructure. By utilizing the established HDMI connection already present in the system, no additional cables or connectors need to be installed, thereby simplifying the installation process and reducing associated costs.
Solution Approach 2:
The existing HDMI interface serves dual purposes: its original function of transmitting media content and the additional function of controlling peripheral devices. This self-service approach allows the same cable and connector to handle multiple communication tasks without requiring separate installation infrastructure.
