Multimedia Box Wake-on-LAN Activation via Meter Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The startup time of multimedia boxes is excessively long, impacting user experience, and existing energy-saving strategies do not effectively reduce this time without increasing energy consumption.
Innovation Solution
Implementing a Wake-on-LAN (WoL) method using an Ethernet data frame to awaken the multimedia box from deep sleep when the user is likely to use it, based on detection of household activity through connected devices such as energy meters or home automation peripherals, allowing the box to transition to a shallow standby state with minimal energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the multimedia box is kept in deep sleep mode to save energy, then energy consumption is reduced, but startup time increases significantly
Solution Approach 1:
The system performs preliminary actions by detecting user presence or device activity before the user actually needs the multimedia box. When a smartphone connects to the network or energy meters detect household activity, the system proactively sends a Wake-on-LAN frame to activate the multimedia box in advance, so that by the time the user wants to use it, the box is already ready, eliminating the perceived startup delay while maintaining deep sleep energy savings.
2Loss of time
If the multimedia box uses Wake-on-LAN to wake up from deep sleep, then startup time is reduced, but network dependency increases
Solution Approach 1:
The system introduces an intermediary mechanism - the Wake-on-LAN network frame - that enables communication between the dormant multimedia box and the activating device. The network acts as a mediator that can trigger box activation without requiring the box to remain constantly powered, allowing the box to stay in deep sleep while still being reachable through the network for selective activation.
3Loss of time
If the multimedia box transitions to shallow standby to reduce startup time, then startup time decreases, but energy consumption increases
Solution Approach 1:
Instead of maintaining shallow standby state continuously, the system uses preliminary detection of user presence or device activity to trigger activation only when needed. The multimedia box remains in deep sleep mode (lowest energy state) and only transitions to active state when the WoL frame is received, combining the energy efficiency of deep sleep with the responsiveness of shallow standby on demand.

AI summary
The method involves detecting use of meter devices (1a-1c) having connectivity with an internet housing (2) by the internet housing, where the use is characteristic of presence of a user to center of a hearth. A frame of activation is sent to the internet housing by a network multimedia box so as to activate a multimedia device (3). The device is a water electricity meter or gas meter, where the use of the device is measurement of a profile of electricity consumption characteristic of the presence of the user to the center of the hearth.
