IR Code Set Mapping for External Device Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying and controlling external electronic devices are cumbersome, often requiring multiple processes and affecting other processes, especially when devices lack identification information or use HDMI CEC and Infoframe, which are not universally applicable.
Innovation Solution
An electronic apparatus that maps an infrared (IR) code set corresponding to an identified external device to a remote control apparatus, allowing for efficient identification and control through a stored database of IR code sets and communication protocols like Bluetooth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If HDMI CEC or Infoframe is used to identify external electronic devices, then device identification can be achieved, but the process becomes complex and affects other processes
Solution Approach 1:
The patent extracts the device identification function from complex protocols (HDMI CEC, Infoframe) and implements it through a dedicated infrared signal receiver that captures and processes remote control signals independently. This separates the identification process from other system functions, reducing overall system complexity while maintaining identification accuracy.
Solution Approach 2:
The patent introduces an intermediary component - the infrared signal receiver and processor - that mediates between the remote control and the electronic device. This intermediary captures remote control signals, processes them to identify the target device, and triggers appropriate functions without requiring direct complex communication protocols between devices.
2Loss of information
If information about external electronic devices is extracted from video data, then device identification is possible, but many processes need to be executed which increases system load
Solution Approach 1:
The patent performs preliminary action by pre-storing device information and characteristics in a database before actual device connection. When a device is connected, the system quickly matches the infrared signal against pre-stored patterns rather than extracting and analyzing video data in real-time, significantly reducing processing load while maintaining accurate device identification.
3Adaptability or versatility
If a universal remote controller is used to control multiple devices, then control versatility is improved, but the remote controller becomes more complex
Solution Approach 1:
The patent implements self-service by enabling the remote control system to automatically identify devices and configure control parameters without user intervention. The system autonomously captures infrared signals, processes them to identify target devices, and sets up appropriate control functions, making the remote controller versatile while keeping the user interface simple.
