Remote-Control Mediated Content Handover for Seamless Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in facilitating seamless playback of contents across different devices, such as smart phones, tablets, and smart TVs, without disrupting the reproduction environment, including settings like aspect ratio, stereophonic effects, and subtitles.
Innovation Solution
A system utilizing short distance communication units, such as NFC or RFID, to transmit data between portable devices and remote controls to synchronize content playback across devices, ensuring continuity of playback settings and environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transferred between devices to enable seamless playback, then playback continuity is improved, but device complexity and data transmission requirements increase
Solution Approach 1:
The patent uses a remote control device as an intermediary to facilitate data transfer between the portable device and the external device. The remote control contains a short distance communication unit that receives data from the portable device and transmits it to the external device, enabling seamless playback without requiring direct complex communication between all devices.
Solution Approach 2:
The system divides the seamless playback functionality into separate components: the portable device stores reproduction environment data, the remote control handles short distance communication and data transmission, and the external device receives and applies the data. This segmentation reduces the complexity burden on any single device.
2Stability of the object's composition
If reproduction environment data is transmitted between devices, then playback settings consistency is improved, but data transmission time and communication overhead increase
Solution Approach 1:
The portable device stores reproduction environment data (including aspect ratio, stereophonic effects, subtitles, and playback position) in advance before playback occurs. This pre-stored data is quickly transmitted via short distance communication when needed, reducing the time required to maintain settings consistency during actual playback transitions.

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 (100) which, when a short distance communication with a remote control (110) which is configured to control an electronic device (120) occurs during reproducing of contents, generates data required by the electronic device (120) for reproducing the contents that are being reproduced, and which transmits the generated data to the remote control (110); the remote control (110) which receives the data from the portable device (100) and which transmits the received data to the electronic device (120), in conjunction with the occurrence of the short distance communication with the portable device (100); and the electronic device (120) for receiving the contents from a contents provider and reproducing the contents.
