HDMI Device Autonomous Power State Control via Activity Data Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in controlling electronic devices connected via HDMI interfaces, as not all devices implement the Consumer Electronics Control (CEO) protocol, leading to fragmented control and increased energy consumption due to lack of compatibility and autonomous management capabilities.
Innovation Solution
A method for autonomous management of electronic devices that detects activity data from connected devices, allowing for automated control and energy-saving commands, such as toggling into standby or shutdown modes, without requiring compatibility between devices, using an HDMI interface and software-based detection and triggering mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the CEO protocol is used for controlling electronic apparatuses, then global control and system simplification are achieved, but compatibility is lost with apparatuses that do not implement the CEO protocol
Solution Approach 1:
The patent introduces an intermediary mechanism that detects activity data from apparatuses regardless of CEO protocol implementation. This mediator translates various control interfaces into a unified control language, enabling the first apparatus to control the second apparatus even when CEO protocol is not implemented, thus resolving the contradiction between global control ease and compatibility
2Ease of manufacture
If proprietary command string protocols are used by different constructors, then device-specific control is optimized, but mutual compatibility between different protocols is lost
Solution Approach 1:
The patent implements a universal detection mechanism that can identify activity data from various proprietary protocols and apparatus types. The first apparatus is configured to detect activity data from the second apparatus regardless of which proprietary protocol the second apparatus uses, enabling a single apparatus to work with multiple different protocol types, thus achieving multi-functionality and resolving the compatibility issue
3Ease of operation
If individual control of each apparatus is implemented, then precise control is achieved, but control complexity and number of remote controls increase
Solution Approach 1:
The patent merges the control functions of multiple apparatuses into a unified control system. The first apparatus combines detection capabilities for activity data from the second apparatus with autonomous decision-making to trigger appropriate commands. This consolidation eliminates the need for separate remote controls for each apparatus while maintaining precise control through activity-based triggering
4Speed
If apparatuses remain in active state to ensure immediate responsiveness, then response time is improved, but energy consumption increases
Solution Approach 1:
The patent implements preliminary action by having the first apparatus continuously detect activity data from the second apparatus and autonomously trigger commands in anticipation of user needs. When activity data indicates the second apparatus is in standby or off state, the first apparatus proactively activates it, ensuring immediate responsiveness without requiring the first apparatus to remain in a high-power state, thus reducing energy consumption while maintaining fast response
