Media Stream Handover Between Smartphones via Server Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smartphone technologies make it cumbersome to combine media streams from multiple devices seamlessly, requiring separate recording and post-editing, which results in timing gaps and visible camera setting discrepancies.
Innovation Solution
A method and system for seamless handover of media stream capturing from a source device to a target device, involving capturing, storing, and synchronizing media streams, with a handover signal that includes camera settings and timing information, allowing for continuous recording without gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate media streams are recorded on multiple smartphones and combined using post-editing tools, then multiple device recording is achieved, but timing gaps and camera setting discrepancies become visible
Solution Approach 1:
The patent merges multiple media stream capture operations into a single unified process by having multiple smartphones record to a common server location simultaneously. This eliminates the need for separate recording sessions and subsequent post-editing combination, thereby maintaining synchronization accuracy while enabling multi-device recording.
Solution Approach 2:
The patent introduces a server as an intermediary component that receives, stores, and manages media stream data from multiple smartphones. This intermediary facilitates synchronized recording by providing a central coordination point, allowing devices to capture content simultaneously without timing gaps or setting discrepancies.
2Adaptability or versatility
If separate media streams are recorded and combined later, then multi-device capture is possible, but additional post-processing work is required
Solution Approach 1:
The patent combines the recording operations of multiple devices into a single coordinated process where all devices capture to the same server location simultaneously. This eliminates the separate post-editing step entirely, as the media streams are already synchronized and combined in real-time during capture, greatly simplifying the operational workflow.
Solution Approach 2:
The system performs automatic synchronization and coordination of multiple devices without requiring manual post-processing intervention. The server automatically manages the media stream data from multiple sources, and the handover mechanism automatically transitions capture responsibility between devices, making the process self-service and eliminating additional work steps.
3Duration of action of stationary object
If a handover mechanism is implemented between source and target devices, then continuous recording is achieved, but system complexity increases
Solution Approach 1:
The server acts as an intermediary that simplifies the handover process between source and target devices. Instead of requiring complex direct communication and coordination between devices, the server manages the handover by receiving data from the source device and redirecting future data to the target device, reducing system complexity while enabling continuous recording.
Solution Approach 2:
The patent extracts the handover coordination logic from the individual smartphones and places it in the server. This separation allows the smartphones to focus solely on their core function of media capture, while the server handles the complexity of managing transitions between devices, thereby reducing device complexity while maintaining continuous recording capability.
Data Source
AI summary
It is provided a method for performing a handover of capturing of a media stream from a source device to a target device. The method is performed in the source device and includes the steps of: capturing the media stream; storing data corresponding to the media stream in a server location; determining a target device; providing a handover signal to the target device, the handover signal including an indication of the server location; receiving a handover response, indicating that handover is accepted by the target device; and determining that media capturing has been handed over to the target device.
