Synchronized Shared Media Sessions for Wearable Battery Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable computing devices, particularly wearable devices, face limitations in media sharing due to size and battery constraints, requiring cumbersome local setups and limiting users to a single channel of media consumption.
Innovation Solution
A system that enables devices to establish a shared media session by receiving independent media streams from a remote media service, synchronized for contemporaneous output, using wireless signals for discovery and offloading power-intensive processes to proxy devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media sharing is implemented on wearable devices, then media sharing functionality is enabled, but battery power is depleted quickly
Solution Approach 1:
A proxy device (smartphone, tablet, or computer) acts as an intermediary between the wearable device and the remote media service. The proxy device handles power-intensive operations including receiving media streams, decoding video content, and managing synchronized playback across multiple devices. The wearable device only performs lightweight tasks such as device discovery, session initiation, and audio output, thereby conserving its limited battery power while enabling full media sharing functionality.
2Adaptability or versatility
If local media sharing setup is used, then media content can be shared, but the setup process is cumbersome
Solution Approach 1:
The system automatically performs device discovery, candidate device list generation, and session establishment without requiring manual configuration. The wearable device and proxy device automatically detect each other's presence, exchange capability information, and negotiate playback parameters. Users simply need to indicate interest in sharing media, and the system handles all technical setup procedures automatically, making the process intuitive and eliminating complexity.
3Adaptability or versatility
If multiple devices share media simultaneously, then full media content is accessible to all users, but synchronization becomes complex
Solution Approach 1:
The proxy device serves as a central coordinator that receives a single media stream from the remote media service and distributes synchronized copies to multiple wearable devices. The proxy device manages playback timing, handles buffer synchronization, and coordinates start/stop commands across all connected devices. This centralized approach allows multiple users to simultaneously access full media content with automatic synchronization, while the complexity of the synchronization mechanism is contained within the proxy device rather than distributed across resource-constrained wearable devices.

AI summary
A first device includes one or more processors configured to determine, based on one or more wireless signals, a candidate device list identifying one or more devices that are within a communication range of one or more sensing devices. The one or more processors are further configured to, based on a determination to initiate a shared media session with a second device of the candidate device list, receive a media stream including particular media content from a remote media service while the particular media content is being sent from the remote media service to the second device. The one or more processors are further configured to, based on the determination to initiate the shared media session, cause the particular media content to be output, based on synchronization information, contemporaneous with output of the particular media content at the second device.
