Wireless Power Control for Bluetooth Audio via AVRCP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling power supply in wireless connections between electronic and audio devices, such as Bluetooth connections, require separate user actions to turn off or on both devices, which is inconvenient.
Innovation Solution
An electronic apparatus with a transceiver and processor that generates and transmits control packets according to a Bluetooth profile to control the power state of an external audio apparatus, allowing synchronized power on/off operations through a single user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate user actions are required to turn off or on both devices, then individual device control is maintained, but user convenience and operational simplicity deteriorate
Solution Approach 1:
The patent merges the control functions of two separate devices (display apparatus and audio apparatus) into a unified power management system. When the display apparatus is turned off, the system automatically transmits a control packet via Bluetooth to turn off the connected audio apparatus, eliminating the need for separate user actions and improving operational convenience.
2Ease of operation
If automatic power control is implemented through control packets, then operational simplicity is improved, but communication protocol compatibility requirements increase
Solution Approach 1:
The patent employs the Audio Video Remote Control Profile (AVRCP) Bluetooth profile, which is a widely adopted universal standard for remote control operations. By using this established profile, the system can automatically control power states of connected audio devices without requiring device-specific custom protocols, thereby maintaining broad compatibility while enabling automated power management.

AI summary
An electronic apparatus, an external apparatus, and a method of controlling a power supply to the external apparatus are provided. The electronic apparatus (200) includes a transceiver (230) configured to wirelessly connect to an external apparatus, a processor (211) configured to control the transceiver to transmit a control command for turning off the external apparatus to the external apparatus in response to an input corresponding to a power off command of the electronic apparatus being received. The control command may be generated according to a profile of a short range communication.
