NFC Interactive TV System Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional broadcast television lacks interactive features that allow viewers to engage with the content of TV programs, despite the introduction of digital and IPTV technologies.
Innovation Solution
A method and system utilizing near field communication (NFC) technologies to encode and package interactive data with audio and video data, enabling interaction with TV programs by transmitting interactive data packets through a digital television network and parsing participatory information using NFC modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional broadcast television is used, then one-way content delivery is achieved, but viewer interaction with TV program content is not possible
Solution Approach 1:
The system segments the TV program content into video packets and interactive data packets, allowing independent processing and transmission of interactive elements separately from the main video stream, enabling interaction without complicating the overall broadcast system
Solution Approach 2:
The patent introduces an intermediary device (such as a set-top box or mobile device with NFC) that mediates between the traditional broadcast television system and the viewer's interaction requests, handling the complexity of interactive processing while the broadcast system remains relatively simple
2Adaptability or versatility
If interactive features are added to digital television and IPTV, then some interaction capabilities are provided, but interaction with present TV program content is still not possible
Solution Approach 1:
The system performs preliminary packaging of interactive data into discrete packets with embedded timing information before transmission, so that when the packets are received, they can be automatically synchronized with the video content without losing synchronization information
Solution Approach 2:
The patent implements a feedback mechanism where the receiving device monitors the playback position of the video stream and uses this information to trigger the transmission and display of interactive data packets at the correct moments, maintaining synchronization between video and interactive content
3Ease of operation
If near field communication module is controlled to transmit interactive data, then viewer interaction with TV content is enabled, but data transmission timing and synchronization must be precisely controlled
Solution Approach 1:
The system pre-packages interactive data with timing metadata indicating when the data should be transmitted and displayed, so that the NFC module can automatically transmit data at the correct moments without requiring complex real-time synchronization control
Solution Approach 2:
The interactive data packets contain self-contained timing information that allows the receiving device to automatically synchronize and display interactive content at the appropriate times without external coordination, simplifying the transmission control requirements
Data Source
AI summary
Interactive data, audio data, and video data are respectively encoded and packaged, and then an interactive television program is produced by multiplexing them. A receiving terminal receives the interactive television program and performs unpacking and decoding. The unpacked interactive data are transmitted by a near field communication module. An operating terminal receives the unpacked interactive data by a near field communication module thereof, parses out corresponding participatory information, and carries out the interaction with the content of the present television program.
