Media Playback Control Transfer Between Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for transferring media playback between electronic devices consume significant battery and processing power, especially when streaming media content, as the source device maintains control and continues to stream audio or video to the destination device, leading to inefficient power usage and limited mobility options for mobile devices.
Innovation Solution
A system and method for transferring media playback control between electronic devices by establishing a peer-to-peer device pairing, evaluating media content characteristics, and determining when to transfer control to the destination device based on local storage availability, allowing seamless playback without interrupting the media experience and reducing power consumption at the source device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the source device maintains control and streams media content to the destination device, then the media playback is continuous and seamless, but the battery consumption and processing power usage increase significantly
Solution Approach 1:
The patent extracts the media streaming function from the source device once control is transferred. When the destination device obtains playback control, it stops receiving and playing streamed content from the source device, thereby eliminating the continuous energy-consuming streaming process while maintaining playback capability through local files.
Solution Approach 2:
The system dynamically switches between two operational modes: streaming mode (source device controls playback) and local playback mode (destination device controls playback). This dynamic transition allows the system to adapt energy consumption to actual needs, using streaming only when necessary and local playback when possible.
2Reliability
If the source device maintains control and streams media content to the destination device, then the media playback is continuous and seamless, but the processing power consumption increases significantly
Solution Approach 1:
The patent extracts the media processing function from the source device once control is transferred. When the destination device obtains playback control, it handles all media processing locally without requiring the source device to decode and stream content, thereby eliminating the continuous processing power consumption at the source.
Solution Approach 2:
The destination device becomes self-sufficient by using its own local media files for playback. Once control is transferred, the destination device independently manages playback without requiring processing resources from the source device, making the system more efficient and reducing the source device's processing burden.
3Use of energy by moving object
If control is transferred to the destination device with local media content, then battery conservation and reduced processing power are achieved, but the media playback may be interrupted if no local copy exists
Solution Approach 1:
The system performs preliminary actions by checking whether the destination device has local copies of media files before transferring control. This advance verification ensures that control transfer will not result in playback interruption, maintaining reliability while enabling energy conservation through local playback.
Solution Approach 2:
The system uses feedback mechanisms to determine whether to transfer control based on the availability of local media at the destination device. This feedback loop ensures that control transfer decisions are made only when they will result in successful local playback, thereby maintaining playback continuity while achieving energy savings.

AI summary
A system and method for transferring control of media playback between electronic devices. Playback of media content is initiating at a source device and peer-to-peer device pairing is established with a destination device. Media content from the source device is streamed to the destination device and a determination of whether to transfer media playback control to the destination device is made based on characteristics of the media content. The control of media playback may be transferred to the destination device based on the destination device having a local copy of the streaming media content, a playlist with similar characteristics to the streaming media content, a local media content having similar characteristics to the streaming media content, or a local playlist similar to the playlist from the source device. The peer-to-peer device pairing is terminated when media playback control is transferred, thereby preserving battery and processing power to the source device.
