NFC FM Channel Sharing for Portable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable terminals with FM transmitters face inconvenience in sharing music with other devices, as they must manually tune FM channels to receive broadcasted music.
Innovation Solution
Implementing near field communication (NFC) to transmit FM channel information and FM radio application execution commands between portable terminals, allowing seamless music sharing without manual channel tuning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual FM channel tuning is used for music sharing, then device compatibility is maintained, but user convenience deteriorates due to manual operation requirements
Solution Approach 1:
The transmitting terminal determines and stores the FM channel information in advance before music sharing occurs. When a sharing request is received, the pre-determined channel information is immediately transmitted to the receiving terminal via NFC, eliminating the need for real-time channel detection and manual tuning operations.
Solution Approach 2:
Near Field Communication (NFC) serves as an intermediary communication channel between the transmitting and receiving terminals. The NFC module transmits the FM channel information and music sharing request efficiently, acting as a mediator that enables automatic channel configuration without manual user intervention.
2Ease of operation
If automatic channel detection is implemented, then user convenience is improved, but device complexity increases due to additional communication protocols
Solution Approach 1:
The patent utilizes existing NFC functionality, which is already integrated into modern portable terminals for other purposes. By repurposing this existing communication module for FM channel information transmission, the patent avoids adding dedicated hardware while achieving automatic channel configuration, thus minimizing the increase in device complexity.
Solution Approach 2:
The receiving terminal automatically receives and processes the FM channel information transmitted via NFC without requiring manual user input. The system performs self-configuration by automatically setting the FM receiver to the transmitted channel, eliminating the need for complex user interfaces or manual tuning mechanisms.

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 wireless music sharing between devices, eliminating the need for manual channel detection and allowing continuous music playback even when the transmitting device is muted.
Implementation Method 1
a first portable terminal for transmitting Frequency Modulation (FM) channel information of an FM transmitter, which is set to broadcast in-play music thereof, and an FM radio application execution command through near field communication (NFC)
Implementation Method 2
Frequency Modulation (FM) channel information of an FM transmitter, which is set to broadcast in-play music

AI summary
Provided is an apparatus and method for playing music, which can play music by simply sharing the music with an external device. An apparatus for playing music includes a first portable terminal and a second portable terminal. The first portable terminal transmits FM channel information of an FM transmitter, which is set to broadcast in-play music thereof, and an FM radio application execution command through near field communication (NFC). The second portable terminal receives the FM channel information and the FM radio application execution command from the first portable terminal through the NFC, then executes the FM radio application based on the FM channel information to receive and play the music broadcasted from the first portable terminal.
