Mesh Network Media Rendering Device Controller Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media rendering systems face disruptions in digital media continuity when users move devices out of network range or attempt to add new devices beyond the WLAN range, and there is a need to control media rendering devices when the controller is within communication range of a rendering device but out of range of a network access point.
Innovation Solution
A method and system that provide limited controller access to a mesh network of media rendering devices by using a secondary network transceiver in a first media rendering device, allowing communication with a third media rendering device beyond the range of the primary network access point, and using a bandwidth-limited secondary network for control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a controller connects directly to the primary network via access point, then network performance and connectivity are optimized, but the controller cannot operate beyond the access point's range
Solution Approach 1:
The patent introduces a mesh network of media rendering devices as an intermediary communication path. When the controller is out of range of the access point, it can still reach the network by communicating with nearby media rendering devices that form a mesh network, allowing control functionality beyond the access point's coverage area
Solution Approach 2:
The patent segments the network into two distinct communication paths: the primary network (access point to controller) and the secondary mesh network (controller to media rendering devices via mesh). This segmentation allows the controller to use different paths depending on its location, optimizing both performance and range
2Adaptability or versatility
If a secondary network is established to extend range, then controller accessibility beyond access point range is enabled, but network bandwidth is limited
Solution Approach 1:
The patent applies partial action by limiting the secondary network's use to control commands only, while high-bandwidth media streaming continues to use the primary network. This partial utilization of the secondary network provides extended range for control functions without significantly impacting overall network bandwidth capacity
3Reliability
If media rendering devices communicate via mesh network, then continuity of media playback is maintained when moving devices, but network complexity increases
Solution Approach 1:
The patent makes media rendering devices multi-functional by enabling them to serve both as media playback devices and as mesh network nodes. This universality allows the same devices to handle both media streaming and network routing functions, maintaining reliability without adding separate dedicated routing hardware

AI summary
A system provides limited controller access to a mesh network of media rendering devices in a primary communication network via an access point providing network connectivity to a local area network (LAN). A first media rendering device in communication with the LAN includes a secondary network transceiver providing a secondary network distinct from the LAN. A second media rendering device is in communication with the first media rendering device via the secondary network. A controller is configured to communicate with the first media rendering device via the LAN and/or the secondary network. The first media rendering device is configured to convey a command from the controller to the second media rendering device via the secondary network.
