Media Context Switching via NFC Channel Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiencies in sharing and accessing media content across devices, requiring multiple steps to switch playback contexts and access specific portions of media items.
Innovation Solution
Implementing near-field-communication (NFC) channels for wireless communication between devices to transfer contextual data, allowing seamless playback switching between electronic devices, enabling efficient sharing and swapping of media items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional methods are used to share media content, then users can access media content, but multiple steps are required including searching, selecting, and navigating to specific portions
Solution Approach 1:
The system performs preliminary actions by automatically detecting and transferring playback context information (including media identifier, playback position, and metadata) between devices before the user needs to access the content. This pre-establishes the sharing state, eliminating the need for manual searching and selection steps.
Solution Approach 2:
The patent introduces an intermediary mechanism (context transfer module using NFC or wireless communication) that mediates the media sharing process between devices. This intermediary automatically handles the complex steps of context detection, data transfer, and playback synchronization, reducing user effort to a simple device proximity action.
2Loss of information
If manual searching and selection is used to access media content, then users can find specific content, but the process is encumbered and time-consuming
Solution Approach 1:
The system creates and transfers a copy of the playback context information (media identifier, playback position, metadata) from the source device to the target device. This copy contains all necessary information to resume playback at the exact same position, eliminating the need for manual searching and navigation.
Solution Approach 2:
The playback context information is prepared and transferred in advance before the user needs to access the content on the new device. This preliminary transfer of contextual data ensures that when the user wants to access the media, all navigation and search steps are already completed.
3Adaptability or versatility
If contextual data is transferred between devices, then seamless playback switching is enabled, but wireless communication channels are required
Solution Approach 1:
The system implements a universal communication approach that can work with multiple wireless communication channels (NFC, Bluetooth, Wi-Fi) through a unified context transfer interface. This multi-functionality allows the same media sharing feature to operate across different device types and communication protocols without requiring device-specific implementations.

Implementation Method 1
a near-field-communication (NFC) channel is established with a second electronic device
Data Source
AI summary
Methods, systems, and/or devices for media context switching among electronic devices are described herein. In one aspect, a method is performed at a first electronic device. A first media item is played. While playing the first media item, a near-field-communication (NFC) channel is established with a second electronic device while the second electronic device is playing a second media item. First contextual data of the first electronic device is transferred via the NFC channel to the second electronic device, wherein the first contextual data corresponds to the first media item. A playback command for the second media item is received. In response to receiving the playback command for the second media item, the first electronic device plays the second media item.
