Third-Party Server Wake Mechanism for Low Power Media Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media content casting systems face challenges in communicating with devices in low power mode, as the media providing service loses direct communication with presentation devices, making it difficult to issue playback commands from a first device to a presentation device in low power mode.
Innovation Solution
The solution involves transmitting a request to a third-party server associated with the presentation device to wake it up from the low power mode, allowing the presentation device to remain in low power mode for longer periods while enabling remote wake-up and reestablishment of communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the presentation device enters low power mode to conserve energy, then energy consumption is reduced, but communication capability with the media providing service is lost
Solution Approach 1:
A third-party server acts as an intermediary between the media providing service and the presentation device. The third-party server maintains a wake connection with the presentation device even when it is in low power mode, allowing the media providing service to send wake requests through the third-party server to restore communication without requiring the presentation device to remain in an active communication state.
Solution Approach 2:
The system establishes a wake connection with the presentation device in advance while it is in low power mode. When communication is needed, the media providing service can send a wake request through the third-party server to preliminarily restore the connection before actual media transmission begins, allowing the device to remain in low power mode for extended periods.
2Reliability
If the media providing service maintains continuous communication with the presentation device to ensure availability, then communication reliability is improved, but the presentation device cannot enter low power mode for prolonged periods
Solution Approach 1:
The third-party server serves as a mediator that maintains a persistent wake connection with the presentation device while the media providing service communicates through this intermediary. This allows the presentation device to remain in low power mode with limited communication, while the third-party server handles the wake requests and maintains the connection state without requiring continuous active communication from the presentation device itself.
3Reliability
If the user directly interacts with the presentation device to wake it from low power mode, then communication is reestablished, but user convenience and interaction requirements increase
Solution Approach 1:
The third-party server acts as an intermediary that receives wake requests from the media providing service and forwards them to the presentation device. This eliminates the need for the user to directly interact with the presentation device to wake it, as the wake requests can be sent automatically through the third-party server from the media providing service, improving ease of operation while maintaining reliable communication reestablishment.

AI summary
A first server system (104) is configured to communicate with a first client device (108) through a first application (420) executing on the first client device. The first server system determines that communication with the first client device through the first application has been lost due to the first client device entering an idle mode. The first server system receives a request from a second client device (102) that triggers reestablishing communication with the first client device through the first application. In response, the first server system transmits a request to a second server system (426) to wake the first client device from the idle mode. The first server system receives, from the first application on the first client device, an indication that communication has been reestablished between the first server system and the first application. The first server system transmits a control command to control the first client device.
