Media Player Wireless Sleep Message Mechanism for Energy Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media players face inefficiencies in energy consumption and limited device information exchange before complete connection, as they continuously maintain communication functions without knowing when relevant data broadcasts occur, leading to unnecessary energy usage.
Innovation Solution
Implementing a wireless sleep message mechanism that allows media devices to turn off their receiving functions for predetermined periods, conserving energy by synchronizing communication based on anticipated message arrival times, and using announcement messages to organize and display nearby device information before full connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If media players continuously maintain communication functions to ensure immediate data reception, then data reception reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic wake-up cycles where the media player alternates between sleep mode and active reception mode. The device wakes up at predetermined intervals to check for messages, then returns to sleep mode. This periodic action maintains the ability to receive data reliably while dramatically reducing energy consumption compared to continuous reception.
2Loss of information
If media players keep receiving functions active to capture broadcast messages, then message reception capability is improved, but power efficiency deteriorates
Solution Approach 1:
The patent employs preliminary action by having media players exchange wake-up schedule information before entering sleep mode. Devices coordinate their wake-up times in advance, allowing them to synchronize message broadcasts with receiver wake-up cycles. This ensures messages are sent only when receivers are active, preventing information loss while avoiding unnecessary energy consumption from continuous monitoring.
3Reliability
If media players perform complete authentication processes before every connection, then connection security is improved, but connection speed deteriorates
Solution Approach 1:
The patent implements preliminary authentication where media players exchange and verify device type information and authentication credentials before establishing a connection. By performing authentication checks in advance during device discovery and message exchange, the system ensures secure connections are established quickly without requiring lengthy authentication protocols during active communication.
Data Source
AI summary
A media player may be adapted to organize and display nearby media device information between communicating media devices before a complete connection is established. In one embodiment, a sleep message is received telling the receiving device to turn off the receiving function for a period of time or until a point in the future to conserve energy.
