Automatic Media Session Transfer via User Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing follow-me television systems require users to manually select a device for media content transfer, disrupting playback and lacking seamless continuity across locations.
Innovation Solution
A system and method for automatic audio-video session transfer between devices in a household, using device and user monitoring means like RFID, inertial navigation, and sensors to detect proximity and initiate seamless playback on a new device without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual device selection is implemented for media content transfer, then device control capability is improved, but user operation complexity increases and playback continuity is disrupted
Solution Approach 1:
The system automatically monitors user location via sensors (GPS, accelerometer, gyroscope) and autonomously transfers playback sessions between devices without requiring user intervention. The mobile device itself serves as the control mechanism, using its own motion data to trigger session transfers when movement thresholds are exceeded.
Solution Approach 2:
The system pre-configures multiple target devices and establishes transfer rules before playback begins. When the user moves to a new location, the system has already prepared the session transfer parameters and can execute the transfer immediately, maintaining playback continuity without user action.
2Ease of operation
If playback session transfer is implemented between devices, then user convenience is improved, but playback continuity may be disrupted
Solution Approach 1:
The system maintains uninterrupted playback during device transfers by using buffer memory to store pre-loaded content and by synchronizing the transfer timing with the user's movement. The playback session continues seamlessly across devices without pausing or interruption, ensuring continuous entertainment experience.
Solution Approach 2:
The system continuously monitors user location and device status through sensors and communication modules, using this feedback to determine optimal transfer moments. This real-time monitoring ensures transfers occur only when appropriate, maintaining playback reliability while enabling follow-me functionality.
3Measurement precision
If multiple monitoring means are integrated for location detection, then transfer accuracy is improved, but system complexity increases
Solution Approach 1:
The mobile device's existing sensors (GPS, accelerometer, gyroscope) are repurposed for location monitoring, eliminating the need for separate dedicated monitoring hardware. This multi-functional approach achieves accurate location tracking while minimizing additional system complexity.
Solution Approach 2:
The system combines multiple sensor inputs (GPS coordinates, acceleration data, orientation information) into a unified location determination mechanism. By merging these monitoring functions into a single integrated system, the patent reduces overall complexity while maintaining high measurement precision through sensor fusion.

AI summary
A method for a follow me television function the method comprising the steps of: receiving an audio video content; processing and delivering the content to a first device at a first location for playback; the method further comprising the steps of: monitoring location of at least one another device by a device monitoring means; monitoring location of a user by a user monitoring means; detecting whether the user is closer to a second device than to the first device currently used for playback; wherein in case the user is closer to the second device than to the first device currently used for playback, transferring the audio video playback session from the first device to the second device; and starting playback of the audio video content on the second device and stopping playback on the first device.
