Voice Recognition Remote Control Setup for EDID-Matched IR Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controls for set-top boxes and TVs require separate operation, leading to inconvenience, and existing voice recognition systems struggle with brand-specific EDID mismatches, causing operational errors.
Innovation Solution
A system utilizing a cloud server to facilitate voice recognition for setting a unified remote control unit (RCU) that registers and downloads IR code information via user voice recognition, allowing seamless control of unregistered devices through over-the-air programming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control is manufactured to control only the set-top box, then the remote control function is simple and reliable, but the user must use separate remote controls for TV and set-top box, reducing convenience
Solution Approach 1:
The remote control is designed to control multiple devices (TV and set-top box) through a unified interface. The controller includes a mapping table that stores correspondence relationships between input signals and remote control signals for different device types, enabling a single remote to replace multiple specialized remotes while maintaining ease of operation
2Reliability
If EDID is pre-set on the remote control to match specific TV brands, then the remote can recognize brand products, but OEM production variations cause EDID mismatches leading to operational errors
Solution Approach 1:
The system performs automatic EDID information acquisition and mapping table generation before actual use. When the remote control first connects to a TV, it automatically obtains the TV's EDID information, generates or updates the mapping table with correct correspondence relationships, and stores this information for future use. This preliminary setup eliminates the need for manual configuration and ensures accurate brand recognition across different OEM variations
Solution Approach 2:
The system implements automatic detection and correction of EDID mismatches. When the remote control attempts to control a TV, it detects whether the current EDID settings match the actual TV brand. If a mismatch is detected, the system automatically acquires the correct EDID information and updates the mapping table, providing feedback-based self-correction that maintains reliability across different TV brands
3Adaptability or versatility
If the remote control automatically acquires EDID information and generates mapping tables, then compatibility with different TV brands is improved, but the initial setup process becomes more complex
Solution Approach 1:
The remote control system performs automatic EDID information acquisition and mapping table generation without requiring user intervention. The controller automatically detects TV brand information, obtains corresponding EDID data, and generates the mapping table autonomously. This self-service approach simplifies the user experience while maintaining high compatibility across different TV brands

AI summary
The present invention relates to a system for configuring a voice recognition remote control unit (RCU) by using a cloud server, and a method therefor. The present invention comprises: a communication interface that performs remotely wireless communication with a product to be controlled, and receives, as an input from the outside, a voice signal for registering product information about the product to be controlled; and an interface configuration unit that compares each of the product information (EDID) with data about the result of recognizing the voice signal by a cloud server where IR code information has been registered as a DB, and allows the IR code information corresponding to the product to be controlled to be configured in the communication interface.
