Audio content playback method and apparatus for portable terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not provide a specialized or optimized method for group simultaneous playback of audio content among portable terminals, limiting the audio listening experience.
Innovation Solution
A method and apparatus for portable terminals that allow group simultaneous playback by checking supportable channels and allocating them based on device position or user input, enabling selective channel allocation and synchronized audio content playback across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If basic content sharing function is provided among portable terminals, then device compatibility and ease of operation are improved, but audio playback quality and synchronization precision deteriorate
Solution Approach 1:
The patent segments the audio playback system into distinct functional modules: a master terminal that manages content source and playback control, and slave terminals that receive and play back audio signals. This segmentation allows each terminal to have optimized functionality - the master handles complex operations while slaves focus on synchronized playback, thereby achieving both ease of operation and playback precision simultaneously
Solution Approach 2:
The patent introduces a playback synchronization signal as an intermediary mechanism between master and slave terminals. This signal carries timing and control information that ensures all terminals synchronize their playback to the same audio content, resolving the contradiction between simple content sharing and precise synchronized playback
2Manufacturing precision
If channel allocation based on position information is implemented, then audio playback quality and spatial accuracy are improved, but device complexity and measurement precision requirements increase
Solution Approach 1:
The patent implements a self-service mechanism where each terminal automatically determines its own position relative to others in the group and autonomously allocates appropriate audio channels based on this position information. This eliminates the need for complex external configuration systems while achieving spatially-accurate audio playback, thereby improving audio quality without proportionally increasing device complexity
Solution Approach 2:
The patent changes the parameter of channel allocation from static or manual assignment to dynamic allocation based on position information. By using position parameters to determine channel assignment, the system achieves spatially-accurate audio playback that adapts to the physical arrangement of terminals, improving audio quality while keeping the allocation logic relatively simple

AI summary
An audio content playback method for a portable terminal. The audio content playback method includes checking a channel that is supportable by audio content that is currently engaged in group's simultaneous playback, in group's simultaneous playback of the audio content. The method includes allocating a channel to each of devices included in a group based on position information of each device included in the group or based on an input state in a user interface environment that is preset for channel allocation for each device included in the group, and transmitting the allocated channel information to each device included in the group to allow the device to select its allocated channel and play the audio content.
