Network Data Playback System Adaptive Role Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless playback systems fail to continue processing network data when playback devices are moved out of their original network range and do not adapt playback roles based on changes in device positions.
Innovation Solution
A network data playback system and method that includes a master device and slave devices, where the slave device estimates its distance from the network circuit and, if beyond a threshold, searches for and connects to another network circuit to continue processing data, while also reassigning playback roles based on updated positions using positioning techniques like Wi-Fi, Bluetooth, or UWB.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless accessory device is moved out of the wireless signal range after its playback role is determined, then the device can no longer process the specific network data, but the conventional techniques do not redetermine the role of the device based on its new position
Solution Approach 1:
The system dynamically determines playback roles based on real-time position information. When a wireless accessory device moves to a new location, the host receives updated position data and redistributes playback roles according to the new spatial arrangement, making the system adaptable to changing configurations while maintaining continuous functionality
Solution Approach 2:
The host continuously monitors position information of wireless accessory devices and proactively determines role redistribution before playback interruption occurs. By anticipating position changes and pre-calculating optimal role assignments, the system ensures seamless transition and continuous data processing without interruption
2Adaptability or versatility
If the host continuously monitors position information to redetermine playback roles, then adaptive role assignment is achieved, but system complexity and processing overhead increase
Solution Approach 1:
Wireless accessory devices autonomously transmit their position information to the host at predetermined intervals or upon detecting significant position changes. This self-service mechanism eliminates the need for continuous active monitoring by the host, reducing system complexity while still enabling adaptive role assignment based on updated positions
Solution Approach 2:
The system implements periodic position information transmission at predetermined time intervals rather than continuous monitoring. This approach balances adaptability with reduced processing overhead, as the host only needs to process position updates at specific intervals and trigger role redetermination when necessary

AI summary
Disclosed is a network data playback system including a network circuit, a master device, and a slave device. The network circuit is configured to provide network resources for the master device and slave device and can be included in or independent of the master device. The master device is configured to select a Uniform Resource Locator (URL) and actively/passively inform the slave device of the URL. The slave device is configured to execute the following steps: if an estimated distance between the slave device and the network circuit is shorter than a threshold, obtaining data (e.g., multimedia data) related to the URL through the network circuit and then processing the data; and if the estimated distance is longer than the threshold, searching for and/or choosing another network circuit to try to continue processing the data related to the URL through the another network circuit.
