Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for seamless playback of contents between different devices, such as smartphones, tablets, and smart TVs, without interruptions or changes in the reproducing environment, including aspects like aspect ratio, 3D stereophonic effects, and subtitles, which existing technologies struggle to maintain consistently.
Innovation Solution
A method and system utilizing near field communication (NFC) for sharing data required for content reproduction between devices, including a portable device, a remote control, and an electronic device, to ensure continuous playback by transmitting and receiving necessary data for maintaining the same reproducing environment across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content reproduction is performed across different devices, then device versatility is improved, but maintaining consistent reproducing environment (aspect ratio, 3D effects, subtitles) becomes difficult
Solution Approach 1:
The portable device performs preliminary actions by detecting NFC contact with the remote control before content transfer, generating and transmitting all necessary reproduction data (aspect ratio, 3D effects, subtitles, playback position) in advance. This ensures the electronic device receives complete environment information beforehand, maintaining consistency across device transitions.
Solution Approach 2:
The remote control serves as an intermediary device between the portable device and the electronic device. It receives NFC contact detection and reproduction data from the portable device, then transmits this data to the electronic device via wireless communication, facilitating seamless content transfer while preserving reproducing environment consistency.
2Reliability
If seamless playback is achieved through data transmission between devices, then playback continuity is improved, but communication complexity increases
Solution Approach 1:
The communication process is segmented into distinct functional stages: NFC contact detection (portable device), data generation and transmission (portable device to remote control), and wireless transmission to electronic device (remote control). This segmentation simplifies the overall complexity by assigning specific tasks to each device component.
Solution Approach 2:
The portable device autonomously detects NFC contact, generates the necessary reproduction data, and initiates transmission without requiring manual intervention. The system performs self-service operations, reducing user burden and simplifying the interaction model despite the underlying communication complexity.

AI summary
A content reproducing method and system for performing seamless playback of contents between devices is provided. The contents reproducing system includes a portable device which, when a short distance communication with a remote control which is configured to control an electronic device occurs during reproducing of contents, generates data required by the electronic device for reproducing the contents that are being reproduced, and which transmits the generated data to the remote control; the remote control which receives the data from the portable device and which transmits the received data to the electronic device, in conjunction with the occurrence of the short distance communication with the portable device; and the electronic device for receiving the contents from a contents provider and reproducing the contents.
