TV Remote Code Learning via Signal Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing universal remote control units often fail to operate with off-brand or newly introduced television sets due to lack of pre-programmed code sets, requiring users to manually select and test codes, which is inefficient and may not always succeed.
Innovation Solution
A television system that learns the control signal data set of a remote control unit by prompting the user to press buttons and storing received data values, allowing it to adapt to unrecognized remote controls, and optionally connecting to external sources for updating remote code data sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If universal remote control units are pre-programmed with code sets, then compatibility with popular television models is improved, but adaptability to off-brand or newly introduced television sets deteriorates
Solution Approach 1:
The television set performs preliminary learning of the remote control unit's code set by capturing and storing the control signals during a dedicated learning period. This preliminary action enables the television to adapt to any remote control unit without requiring pre-programmed codes, resolving the contradiction between pre-programming limitations and adaptability requirements.
Solution Approach 2:
The television set serves itself by automatically learning and storing the remote control unit's code set without requiring user intervention to manually program or select codes. This self-service mechanism eliminates the need for users to navigate code lists or perform manual configuration, thereby improving both adaptability and reliability simultaneously.
2Reliability
If users manually select and test codes to match the television model, then code set accuracy is improved, but user effort and time consumption increase
Solution Approach 1:
The television set automatically captures and stores the remote control unit's code set without requiring users to manually select or test codes. The system performs this learning process autonomously during a designated period, eliminating user effort while ensuring accurate code set matching.
Solution Approach 2:
The system uses feedback from the remote control unit's transmitted signals to automatically identify and store the correct code set. By monitoring the control signals and comparing them against stored patterns, the television set confirms the match and activates the learning mode, ensuring accuracy without user intervention.
3Adaptability or versatility
If the television set learns the remote control unit's code set, then adaptability to various remote controls is improved, but device complexity increases
Solution Approach 1:
The television set's existing receiver and processor are utilized to perform the learning function, rather than adding dedicated hardware. The same components that handle normal signal reception are also employed to capture, process, and store remote control code sets, thereby achieving multi-functionality without increasing device complexity.
Solution Approach 2:
The learning mechanism is integrated into the television set's existing software and processor architecture, allowing it to autonomously perform code set learning without requiring separate hardware modules. This self-service approach leverages existing computational resources to achieve adaptability while minimizing added complexity.
Data Source
AI summary
A television set which learns to work with a remote control unit not specifically designed to operate that television set. The television set enters a learning mode in response to the user pressing a “Learn Remote” button or menu item, or in response to receiving an unknown remote control signal value, and gives the user a series of prompts for the user to press specified buttons on the remote control unit. As the user presses the buttons, the television set associates the received data values with the prompted button/functionality, to construct the remote code data set of the remote control unit. The television set may retrieve the remote code data set from an external source such as a website. After learning the remote code data set, the television set is able to be controlled by the remote control unit as though it were factory original.
