Broadcasting Device Synchronization via User Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in seamlessly transitioning an audiovisual broadcast from one room to another in a multi-room environment, as existing methods require manual intervention and do not allow for automatic continuation of the broadcast.
Innovation Solution
A method and system that utilize connected devices to detect user movement and automatically synchronize audiovisual broadcasts across different equipment, using a router and wireless protocols like Bluetooth to send and receive distance messages, ensuring seamless continuation of the broadcast without the need for additional devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual intervention is used to switch between broadcasting devices in different rooms, then the user can control the broadcast, but the operation becomes complex and time-consuming
Solution Approach 1:
The system automatically detects user presence using sensors and autonomously switches the audiovisual broadcast between broadcasting devices without requiring manual user intervention. The broadcasting devices self-manage the transition based on detected user location, eliminating the need for users to manually operate switches or controls when moving between rooms.
Solution Approach 2:
The system continuously monitors user presence and location through sensors (motion detectors, proximity sensors) and uses this feedback to automatically adjust which broadcasting device is active. When a user approaches a room with a different broadcasting device, the system detects this change and automatically switches the broadcast to the appropriate device, creating a closed-loop control system that responds to user movement.
2Adaptability or versatility
If multiple independent decoders are used in different rooms, then each device can display different programs, but the system complexity increases
Solution Approach 1:
The patent combines multiple broadcasting devices into a coordinated system where they share control logic and communication protocols. Rather than treating each decoder as completely independent, the devices are merged into a unified networked system that manages program distribution centrally while allowing local display flexibility, reducing overall system complexity.
Solution Approach 2:
Each broadcasting device is designed to be universal and interchangeable within the system. All devices can display any program from the available channels, and they all follow the same control logic for switching and program selection. This universality means users don't need to configure different settings for different devices - the system handles program distribution uniformly across all locations.
3Extent of automation
If automatic detection of user movement is implemented, then broadcast switching becomes seamless, but additional sensors and detection equipment are required
Solution Approach 1:
The system uses an intermediary communication network (wireless network, Bluetooth, or other communication protocols) to transmit user presence information between the detection point and the broadcasting devices. Rather than requiring direct complex sensor integration in each device, the intermediary network handles the communication burden, allowing broadcasting devices to remain relatively simple while still achieving automatic switching through networked coordination.

AI summary
The invention relates to a method for tracking an audiovisual broadcast between at least a first and a second broadcasting device (21, 22, 23) connected via a router (24) and each capable of at least partially broadcasting the audiovisual broadcast. Each of said broadcasting devices comprises a processing unit, memory, and at least one interface (50) for tracking a connected device (30) associated with a user. The method comprises the following operations: - detection, by the first broadcasting device, of the distance (120) of the connected device from said first broadcasting device; - sending (130), by the first broadcasting device, of a distance message (300) to all broadcasting devices connected to the router, this distance message including a time delay for the audiovisual broadcast; - verification, by each of the broadcasting devices connected to the router,of the approach of the connected device, - detection (140), by the second broadcasting equipment, of the approach of the connected device (30) associated with the user, - broadcasting of the audiovisual program (150), by the second broadcasting equipment, according to the timing data transmitted by the first broadcasting equipment in the relocation message (300), and - transmission, by the second broadcasting equipment, of an acknowledgment message (160) to all broadcasting equipment.
