Portable Device Motion Sensor Reduces TV Booting Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital TVs experience prolonged booting times when transitioning from standby to operational mode, which is a limitation due to hardware constraints and affects user experience, especially when users want to quickly access content.
Innovation Solution
A method and system where a portable device, equipped with a motion sensor, controller, and communicator, senses movement to convert from standby to normal mode, generates a pre-power on signal, and transmits it to the digital TV using Bluetooth, ZigBee, or Wi-Fi, activating essential elements before full power-on, thereby reducing booting time.

Engineering Contradiction Analysis
1Speed
If the digital TV is turned on from standby mode, then the TV can display content and perform functions, but the booting time is prolonged due to hardware limitations
Solution Approach 1:
The patent applies preliminary action by detecting user movement (picking up the remote controller) before the actual power-on command is given. The system pre-activates necessary components and loads required data in advance, so that when the user presses the power button, the TV is already partially prepared and can display content much faster, effectively reducing the perceived booting time.
2Use of energy by moving object
If the TV is kept in standby mode to save power, then energy consumption is reduced, but the responsiveness when turning on is slower
Solution Approach 1:
The system performs preliminary actions during standby mode by monitoring for user presence through motion sensors. When movement is detected, the TV pre-loads content and activates components before the user actually requests power-on, maintaining low power consumption during true standby while achieving fast responsiveness when needed.
Solution Approach 2:
The patent implements dynamic power management where the TV transitions through multiple intermediate states between full standby and full operation. Based on user behavior detection, the system dynamically adjusts which components remain active during standby, optimizing the balance between power consumption and responsiveness for different usage scenarios.

AI summary
A portable device, a display apparatus, a display system, and a method for controlling power of a display apparatus thereof are provided. The method includes sensing, while a portable device operates in a standby mode, a movement of the portable device using a motion sensor, converting, using the portable device, the standby mode of the portable device into a normal mode in response to the movement of the portable device being sensed, generating, using the portable device, a pre-power on signal in response to the standby mode being converted into the normal mode, transmitting the pre-power on signal to the display apparatus, and activating, by the display apparatus, some elements of the display apparatus in response to the pre-power on signal being received.
