NFC Master Device Routing Media Content to Slave Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile wireless communication systems lack an efficient method for distributing content items to multiple devices with varying media playback features and capabilities, leading to inefficient content routing and playback.
Innovation Solution
A communications system comprising a master mobile wireless device with a processor that uses NFC technology to associate and send different content items to slave devices based on their media playback features, such as video, audio, or text capabilities, and playback quality, allowing for quick and easy distribution and optimal playback on compatible devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If content items are distributed to multiple slave devices without NFC-based capability detection, then distribution speed is improved, but content routing efficiency deteriorates due to mismatch between content types and device capabilities
Solution Approach 1:
The master device performs preliminary NFC communication with each slave device to detect and store media playback capabilities before content distribution. This preliminary capability detection enables the master device to intelligently route content items to appropriate slave devices based on their capabilities, resolving the contradiction between fast distribution and efficient routing.
2Adaptability or versatility
If all content items are sent to all slave devices, then content availability is improved, but device complexity increases due to handling multiple content types on devices with varying capabilities
Solution Approach 1:
Each slave device receives only the content items matching its local media playback capabilities. The master device filters and routes content based on detected capabilities, ensuring each slave device handles only appropriate content types. This local quality approach maintains content availability while reducing complexity at each device.
3Ease of operation
If content is routed without matching media playback features, then distribution simplicity is improved, but playback quality deteriorates due to incompatibility between content and device capabilities
Solution Approach 1:
The master device uses NFC communication to receive feedback about each slave device's media playback capabilities and uses this feedback information to intelligently route content items. This feedback mechanism maintains distribution simplicity while ensuring reliable playback quality by matching content types with device capabilities.

AI summary
A communications system includes a plurality of slave mobile wireless communications devices each having a first near field communications (NFC) device. The communications system also includes a master mobile wireless communications device having second NFC device, and a processor coupled to the second NFC device. The processor is configured to associate different content items with different respective slave mobile wireless communications devices, based upon NFC communication with the plurality of slave mobile wireless communications devices, and to send the different content items to the different respective slave mobile wireless communications devices.
