Remote User Interface Control Transfer in Satellite TV Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In satellite television systems, controlling user interfaces to prevent conflicts between server and client devices is challenging, as existing systems often require manual intervention to manage customizable features like program guides, audio, and video settings, which can lead to user experience inconsistencies.
Innovation Solution
A distributed system where a server device communicates with one or more client devices to control user interfaces, allowing for seamless transfer of control between remote and native interfaces, ensuring that only one device controls the display at a time, thereby preventing conflicts and enhancing user customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control of user interface is distributed to both server and client devices, then user customization capability is improved, but control conflicts arise between devices
Solution Approach 1:
The system dynamically transfers control between server and client devices based on operational context. The server can initiate control transfer to the client device when appropriate, and control can be transferred back to the server when needed, creating a flexible control architecture that adapts to different usage scenarios while maintaining system reliability
Solution Approach 2:
The system implements feedback mechanisms where the server receives status information from the client device and can initiate control transfer based on this feedback. The client device also provides feedback about its control state, enabling the server to maintain awareness and reliability of the distributed control system
2Measurement precision
If manual intervention is used to manage user interface controls, then control precision is improved, but user experience consistency deteriorates
Solution Approach 1:
The client device is empowered to autonomously manage its own user interface controls without requiring manual intervention from the server for each control action. The client device can independently handle program guide, audio, and video settings, providing consistent user experience while maintaining precise control through its own local decision-making
3Reliability
If server controls all user interface functions, then system reliability is improved, but device complexity increases
Solution Approach 1:
The control architecture is segmented into distinct server and client device functions. The server handles high-level control decisions and coordination, while the client device handles local user interface management. This segmentation reduces overall system complexity by distributing responsibilities appropriately rather than concentrating all control functions in one device
Data Source
AI summary
A method and system for controlling a user interface displayed at a client device includes a client device and a server device that communicates a first remote user interface from the server device to the client device. The client device displays the first remote user interface and communicates key signals to the server device. The server device communicates a first transfer control signal to the client device. The client device displays a client native interface and communicates a second transfer control signal to the server device. The server device communicates the second remote user interface to the client device. The client device displays a second remote user interface at the client device.
