Audio Playback Relay via Near Field Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio playback technologies require tedious operations to switch and disconnect audio between terminals and playback devices, limiting relay playback functionality to only between the terminal and audio playback device.
Innovation Solution
An audio playback control method and apparatus that utilizes near field communication to switch media content playback between multiple audio playback devices, allowing seamless relay playback by triggering playback on a first device when in communicable distance and switching to a second device when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operations are used to switch audio playback between terminals and devices, then playback switching can be achieved, but the operation process becomes tedious and complex
Solution Approach 1:
The system automatically detects the presence of audio playback devices through near field communication and autonomously switches playback without requiring manual user operations. The terminal device self-manages the playback switching process by detecting communicable devices and initiating playback transfer automatically.
Solution Approach 2:
The system performs preliminary detection of available audio playback devices using near field communication before actual playback switching occurs. This advance preparation enables rapid switching by having potential target devices already identified and ready to receive playback.
2Reliability
If relay playback is limited only between terminal and audio playback device, then connection management is simplified, but playback continuity is interrupted when users move between different devices
Solution Approach 1:
The relay playback system is extended to support multiple audio playback devices beyond just a single terminal-device pair. The system can detect and manage playback across terminal devices, first audio playback devices, and second audio playback devices, enabling flexible multi-point relay playback that adapts to user movement and device availability.
3Adaptability or versatility
If automatic switching between multiple audio playback devices is implemented, then playback continuity is maintained, but the system complexity increases
Solution Approach 1:
Near field communication serves as an intermediary mechanism that simplifies the complexity of managing multiple audio playback devices. By using NFC as the detection and triggering medium, the system reduces the complexity of device discovery and switching management while maintaining the ability to seamlessly transition playback across multiple devices.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple and fast switching between multiple audio playback devices, ensuring continuous media playback as users move between different devices, such as from a terminal to a speaker and then to a TV, without interrupting the audio experience.
Implementation Method 1
a distance between the terminal and the first audio playback device reaching a communicable distance for near field communication
Data Source
AI summary
A audio playback control method includes: triggering switching audio of media content played on a terminal to a first audio playback device for playback in response to a distance between the terminal and the first audio playback device reaching a communicable distance for near field communication during a process of playing the media content on the terminal; and switching the audio of the media content played on the first audio playback device to a second audio playback device for playback in response to the second audio playback device being triggered to play the media content during a process of playing the media content on the first audio playback device.
