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

VSEngineering Contradiction Analysis

1Ease of operation

If basic content sharing function is implemented using NFC, then device compatibility and ease of operation are improved, but audio playback quality and channel allocation capability deteriorate

Engineering Contradiction:
Improveease of operationVSAvoidadaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts channel allocation based on device position information and user interface states. The master terminal adjusts channel assignments in real-time during group simultaneous playback, allowing the system to transition from basic content sharing to optimized audio playback based on operational conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes operational parameters by checking supportable channels and allocating specific channels (e.g., left channel, right channel) to different devices based on their positions. This parameter optimization enables specialized audio playback while maintaining compatibility with existing NFC-based content sharing infrastructure.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If channel allocation based on position information is implemented, then audio playback quality and adaptability are improved, but device complexity and measurement precision requirements increase

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the audio content into different channels (e.g., left channel, right channel) and allocates them to specific devices based on position information. This segmentation allows specialized audio playback while keeping each device's processing requirements manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The master terminal acts as an intermediary that collects position information from all devices, determines optimal channel allocation, and distributes channel assignments to group members. This intermediary approach centralizes the complexity of position-based allocation while keeping individual device complexity low.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If group simultaneous playback with channel allocation is implemented, then audio listening experience and adaptability are improved, but loss of information and device complexity increase

Engineering Contradiction:
ImproveadaptabilityVSAvoidloss of information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system implements feedback mechanisms where the master terminal checks supportable channels of audio content and monitors device position information. Based on this feedback, the system adjusts channel allocation to optimize audio playback while ensuring all devices can process their assigned channels, preventing information loss.

Inventive Principle:
Principle #23Feedback

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.
