Remote Control Protocol Identification via Signal Characteristic Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media processing devices often struggle to recognize and interpret command signals from a variety of remote control devices, including secondary remote controls, which can use different protocols and formats, limiting their compatibility and functionality.
Innovation Solution
A media processing device is configured to compare characteristics of wireless signals from remote controls to identify the protocol used, allowing it to map command signals to functions it can perform, and to store and manage profiles for multiple remote control devices, enabling the use of secondary remote controls and providing visual indicators for recognized commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a media processing device is configured to recognize only a predetermined set of command signals from a primary remote control device, then the device can reliably interpret commands, but it cannot accommodate secondary remote control devices with different protocols and formats
Solution Approach 1:
The media processing device is configured to perform multiple functions: it can recognize command signals from both primary remote control devices using predetermined protocols and secondary remote control devices using different protocols and formats. The system maintains a library of multiple protocols and can adaptively select and interpret commands from various remote control types, making the device universally compatible with diverse remote controls while managing complexity through structured protocol handling
2Adaptability or versatility
If a media processing device is configured to recognize command signals from multiple remote control devices with different protocols, then compatibility is improved, but the complexity of recognizing and interpreting diverse command formats increases
Solution Approach 1:
The system introduces an intermediary protocol identification and translation layer between the diverse remote control devices and the media processing device. This intermediary component receives command signals, identifies the protocol used, translates the commands into a standardized internal format, and routes them to the appropriate processing function. This mediator approach enables compatibility with multiple remote control types while shielding the core processing logic from protocol complexity
Solution Approach 2:
The system dynamically changes operational parameters by detecting protocol-specific characteristics of incoming command signals and adapting its interpretation parameters accordingly. When a command signal is received, the system identifies the protocol type and adjusts its recognition parameters to match the specific format, timing, and encoding rules of that protocol, enabling accurate interpretation of diverse command formats without requiring separate processing paths for each protocol

AI summary
Methods, systems, and apparatus for identifying protocols. In one aspect, a method includes comparing characteristics of a wireless signal received from a remote control to characteristics associated with a set of protocols. The method also includes assigning a score, based upon the comparison, to each protocol included in the plurality of protocols. The method also includes identifying a protocol from the set of protocols based upon the assigned scores. The identified protocol is substantially similar to a protocol associated with the wireless signal.
