Conditional Tuner Activation for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices incur unnecessary costs due to the activation of tuners and codecs even when not in use, leading to unwanted license fees and power consumption, as existing techniques fail to effectively prevent tuner activation when not required.
Innovation Solution
A system that includes a display device capable of sending activation notifications to a server to determine if a tuner or codec should be activated based on signal strength and type, allowing for conditional activation and deactivation, and offering a rebate for non-use scenarios, with a store mode for activating components without licensing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tuner is activated to ensure it can decode digital signals, then the reliability of signal reception is improved, but unnecessary power consumption and license fees occur when the tuner is not in use
Solution Approach 1:
The tuner's activation state is made dynamic rather than static. The system automatically transitions the tuner between active and inactive states based on real-time detection of user access attempts to digital channels. When a user attempts to access a digital channel, the tuner is activated; when no access is attempted, the tuner is deactivated, optimizing both reliability and power consumption.
Solution Approach 2:
The system implements self-service automation where the tuner automatically activates and deactivates based on detected user behavior patterns. The processor monitors access attempts and autonomously controls tuner activation without requiring manual user intervention, thereby reducing unnecessary power consumption while maintaining signal reception reliability when needed.
2Ease of operation
If the tuner is continuously activated to ensure availability, then the ease of operation is improved, but unnecessary license fees and power consumption increase
Solution Approach 1:
Instead of continuous activation, the system employs periodic activation based on detected user access attempts. The processor continuously monitors for access attempts to digital channels and activates the tuner only during these periodic intervals when needed, rather than maintaining continuous operation, thereby reducing power consumption while preserving ease of operation when users actually need the tuner.
Solution Approach 2:
The system performs preliminary detection of user access attempts before activating the tuner. The processor monitors for access attempt signals and only activates the tuner when such preliminary detection occurs, ensuring the tuner is available exactly when users need it without the energy waste of continuous activation.
3Productivity
If the tuner is activated without verification of signal decodability, then the productivity of channel access is improved, but unnecessary costs are incurred when the signal cannot be decoded
Solution Approach 1:
The system implements feedback control where the processor detects whether the tuner can successfully decode the digital signal before maintaining activation. If the signal cannot be decoded, the system receives feedback about this failure and deactivates the tuner, preventing unnecessary power consumption. This feedback mechanism ensures productivity is maintained only when actual decoding success occurs.
Solution Approach 2:
The system replaces blind mechanical activation with intelligent software-based detection and control. The processor uses software logic to detect access attempts and verify decoding capability before activating the tuner, substituting automated digital control for traditional always-on hardware activation, thereby eliminating unnecessary power consumption while maintaining channel access efficiency.

AI summary
A device configuration for determining whether to send an activation notification based on whether a signal can be decoded by a tuner or codec are described herein. For example, a device may include a tuner, activated in response to receiving the user indication, to attempt to decode a signal corresponding to a channel, and a processor to execute instructions that: detect, prior to a start of a delay period, that the tuner is required to decode the signal, determine, during the delay period, whether the signal can be decoded by the tuner, deactivate the tuner after the delay period without sending a tuner activation notification, in response to a determination that the signal cannot be decoded by the tuner, and send the tuner activation notification to a remote server after the delay period, in response to a determination that the signal can be decoded by the tuner.
