Audio Video Node Routing Graphical User Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing graphical user interfaces for televisions and set-top boxes are cumbersome, as they only display source names like 'Video 1' without indicating the connected device type, making it difficult for users to manage multiple source and target nodes effectively.
Innovation Solution
A graphical user interface (GUI) that visually represents audio/video device nodes and signal flows, allowing users to easily route signals between source and target nodes by manipulating GUI elements, providing a clear understanding of node connections and enabling seamless switching between sources and targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional user interfaces are used with multiple source and target nodes, then the device can receive inputs from multiple sources and direct them to various target nodes, but the user interface becomes unwieldy and difficult to operate
Solution Approach 1:
The user interface is segmented into distinct visual representations of source nodes, target nodes, and signal flow paths. Each node is displayed as a separate graphical element with its specific function and connection status clearly indicated, allowing users to navigate the complex multi-source multi-target system without confusion.
Solution Approach 2:
The patent introduces an intermediary graphical representation layer between the physical nodes and the user's control actions. This visual intermediary shows the current signal routing state and allows users to make informed decisions about signal direction without needing to understand the underlying complex connection architecture.
2Device complexity
If only source names are presented to the user, then the interface remains simple, but the source names are obscure and do not provide indication of the type of device connected
Solution Approach 1:
Each source node and target node is displayed with locally relevant information specific to that node's function and connection state. Source nodes show their device type and connection status, while target nodes display their function and current signal source. This localized information presentation maintains interface simplicity while providing comprehensive device information.
3Reliability
If users need to know how the television and peripheral devices were set up to identify correct sources, then accurate signal routing can be achieved, but the operation becomes difficult and time-consuming
Solution Approach 1:
The interface provides continuous visual feedback showing the current signal routing configuration. When a user selects a source node or target node, the system immediately displays the current path and allows users to see the effect of their selections in real-time, eliminating the need to remember previous device setups and reducing selection errors.

AI summary
A graphical user interface (GUI) is described. The GUI includes first GUI elements that provide a visual representation of the nodes of an audio/video device. In response to user input, a signal is caused to be routed between nodes by manipulating circuitry within the audio/video device. Second GUI elements provide a visual representation of the signals being routed within the electronic device between pairs of first GUI elements (e.g., between nodes). As a result, the user can readily understand which nodes are connected to each other. Thus, for example, a user can easily visualize which source node is providing input to a target node and, by selecting the appropriate GUI elements, can just as easily switch from one source to another or from one target to another.
