Adaptive Boot Time Threshold for Peripheral Power State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integrated remote controllers fail to accurately determine the booting state of peripheral devices, leading to incorrect user interface displays and prolonged content output delays, as they may mistakenly recognize a peripheral device as powered off during booting, causing users to perceive malfunctions.
Innovation Solution
A method and apparatus for a display apparatus that transmits a turn-on signal to a peripheral device, measures the time interval for content reception, and sets a threshold time to determine the device's operation state, allowing for accurate power state determination and minimizing content output delays by adjusting control operations based on the measured interval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display apparatus uses a fixed time threshold to determine peripheral device power state, then the control logic is simple, but the determination accuracy is low causing false power-off detection during booting
Solution Approach 1:
The patent applies dynamics by making the time threshold adaptive rather than fixed. The system dynamically adjusts the time threshold based on the actual boot time of the peripheral device. During booting, the display apparatus measures the time from when the turn-on signal is sent to when the peripheral device responds, and uses this measured time as the threshold for subsequent power state determinations. This dynamic adjustment resolves the contradiction by improving determination accuracy while keeping the control logic relatively simple.
Solution Approach 2:
The patent implements feedback by using the actual boot time measurement to adjust the time threshold for power state determination. The system measures the boot time during the initial startup phase, then feeds this information back to set an appropriate threshold that prevents false power-off detections. This feedback mechanism ensures accurate power state determination during the entire operation cycle, including the booting phase.
2Reliability
If the display apparatus waits for peripheral device booting completion before displaying content, then power state determination is accurate, but content output time is prolonged
Solution Approach 1:
The patent applies preliminary action by measuring the boot time during the initial startup phase and establishing the time threshold before content playback begins. This preliminary measurement allows the system to configure appropriate waiting periods or timeout thresholds in advance, ensuring that subsequent power state determinations are accurate without requiring excessive waiting time during actual content output.
Solution Approach 2:
The system dynamically sets the time threshold based on the actual measured boot time rather than using a fixed conservative threshold. This dynamic adjustment allows the system to optimize the balance between waiting for device readiness and minimizing content output delay, adapting to different peripheral devices with varying boot times.
3Reliability
If the integrated remote controller retransmits IR signal during peripheral device booting, then the peripheral device can reboot, but content output time increases and user perceives malfunction
Solution Approach 1:
The patent uses feedback by monitoring whether the peripheral device responds within the dynamically determined time threshold after receiving the turn-on signal. If the device responds within the threshold, the system recognizes successful booting and does not trigger retransmission. If the device fails to respond within the threshold, then the system determines the device is truly powered off and initiates appropriate error handling. This feedback-based approach prevents unnecessary retransmissions during normal booting, reducing content output delay while maintaining operational reliability.
4Ease of operation
If the display apparatus provides power control UI during peripheral device booting, then user can control the device, but user misperceives device malfunction
Solution Approach 1:
The patent applies dynamics by making the user interface adaptive to the device's operation state. The system dynamically determines whether to display the power control UI based on the elapsed time since the turn-on signal and the dynamically set threshold. During the booting period (within the threshold), the system suppresses the power control UI to prevent user misperception. Only when the device fails to respond within the threshold does the system display the UI, indicating true power-off state. This dynamic UI adjustment resolves the contradiction by preserving user control capability while preventing loss of operation state information.

AI summary
A display apparatus for controlling a peripheral device and a method thereof are provided. The method may include transmitting, to a remote controller, a first turn-on signal to turn on the peripheral device; measuring a time interval between a first time when the display apparatus transmits the first turn-on signal to the remote controller and a second time when the display apparatus starts to receive content from the peripheral device in response to the first turn-on signal; and setting the measured time interval as a threshold time to determine whether the content is received from the peripheral device.
