NFC Remote Control for Seamless Cross-Device Content Playback
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, as users want to continue watching or listening to media across various devices without interruptions, and existing technologies lack efficient methods for achieving this seamless transition.
Innovation Solution
A method and system utilizing short distance communication, specifically Near Field Communication (NFC), to share data required for content reproduction between devices, allowing for continuous playback by detecting NFC contact and transmitting necessary data between portable devices, remote controls, and electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contents are reproduced on multiple devices, then user convenience is improved, but data transmission complexity increases
Solution Approach 1:
The patent introduces a remote control device as an intermediary component that facilitates seamless playback between portable devices and electronic devices. The remote control receives data from the portable device and transmits it to the electronic device, simplifying the overall data transmission process. This intermediary approach reduces the complexity of direct peer-to-peer communication while enabling cross-device content continuation.
2Duration of action of moving object
If data is transmitted between devices for seamless playback, then playback continuity is improved, but transmission time increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring the remote control device with the necessary data transmission capabilities and establishing communication protocols before actual playback occurs. The system prepares data packets and transmission parameters in advance, enabling rapid data transfer when playback needs to continue on a different device, thereby minimizing transmission time while maintaining continuity.
3Manufacturing precision
If multiple parameters are maintained during playback transition, then reproduction quality is improved, but data processing complexity increases
Solution Approach 1:
The patent extracts and isolates specific playback parameters (such as audio settings, video quality, and playback position) from the overall data transmission process. By identifying and separating these critical parameters, the system can focus transmission resources on maintaining essential reproduction quality while simplifying the management of less critical settings, thus reducing overall processing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables seamless playback of contents across devices by ensuring continuous data transmission and synchronization, maintaining parameters like caption settings, sound settings, and resolution, allowing users to seamlessly switch between devices without losing their media experience.
Implementation Method 1
The short distance communication may be based on at least one near field communication (NFC) standard.
Data Source
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.
