Solution Overview
Problem
Broadcast media, such as television and radio, typically have unidirectional signal flows and lack effective bidirectional communication with electronic devices, limiting the ability to transmit and utilize embedded data like coupons or advertisements.
Innovation Solution
A broadcasting system that includes a transmitter broadcasting a one-way signal with embedded data, which can be received by a device with NFC components, allowing communication between devices to process and utilize this data, including transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If broadcast media use unidirectional signal transmission, then signal coverage and simplicity are improved, but bidirectional communication capability deteriorates
Solution Approach 1:
The patent introduces NFC components as an intermediary communication channel between broadcast devices and mobile devices. The broadcast device embeds data in the transmitted signal, and the NFC component in the mobile device detects and processes this embedded data, enabling bidirectional interaction while maintaining the simplicity of unidirectional broadcast transmission.
2Loss of information
If broadcast signals contain embedded data, then information transmission capability is improved, but data extraction and utilization capability deteriorates
Solution Approach 1:
The patent implements a system where the mobile device's NFC component automatically detects and extracts embedded data from broadcast signals without requiring manual intervention. The software application on the mobile device then processes and utilizes this data automatically, making the data extraction and utilization process self-serving and eliminating the need for user action.
3Device complexity
If broadcast devices lack NFC components, then device simplicity is improved, but data exchange capability with mobile devices deteriorates
Solution Approach 1:
The patent extracts the NFC communication functionality specifically to the mobile device side, where the NFC component and software application reside. The broadcast device maintains its simplicity without requiring NFC components, while still achieving data exchange capability through the mobile device's NFC component detecting embedded data in the broadcast signal.

Data Source
AI summary
A broadcasting system having a transmitter that broadcasts a one-way signal is provided. The one-way signal is embedded with data that is transmitted to a device that is enabled with near field communication (NFC) technology. The NFC-enabled device may then transfer at least a portion of the transmitted embedded data to another NFC-enabled device by bringing the NFC-enabled devices into close proximity to each other.
