Display Interface Auto-Detection for Multi-Source Media Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to select the correct video interface on display devices due to unfamiliarity with interface names like HDMI, DP, and VGA, leading to inconvenience in displaying media data from multiple source devices.
Innovation Solution
An electronic device with multiple interfaces that can obtain and process media data from connected source devices, generating presentation data to indicate correspondences between interfaces and media data, allowing users to select the correct interface based on the presentation data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video interfaces are arranged on a display device, then the device can receive media data from multiple source devices, but users find it difficult to select the correct interface due to unfamiliarity with interface names
Solution Approach 1:
The patent introduces an intermediary system (the display device itself with its processing capabilities) that automatically detects connected source devices, obtains their media data, and generates presentation data. This intermediary action bridges the gap between multiple interfaces and user-friendly selection, eliminating the need for users to understand technical interface names while maintaining the ability to receive data from multiple sources.
Solution Approach 2:
The system implements feedback by generating presentation data that displays information about connected source devices and their corresponding interfaces. This feedback loop allows users to see which devices are connected to which interfaces and make informed selections without needing to know technical interface specifications, thus resolving the contradiction between multi-interface capability and ease of selection.
2Productivity
If the display device only displays media data from selected interfaces, then it can show source device media data, but users need to understand interface names to make selections
Solution Approach 1:
The patent creates a simplified copy or representation of the interface selection process through presentation data. Instead of requiring users to directly interact with complex interface names and specifications, the system generates an simplified interface that copies only the essential information needed for selection (device names, connection status), thereby maintaining productivity while reducing perceived complexity.
Solution Approach 2:
The system segments the interface selection process into distinct components: detection of connected devices, generation of presentation data, and user selection. By separating these functions, the patent maintains the ability to handle multiple data sources while simplifying the user-facing selection process, as users only need to interact with the segmented presentation layer rather than the full complexity of the underlying interface system.
Data Source
AI summary
An electronic device includes a first interface configured to obtain a first media data of a first source device; a second interface configured to obtain a second media data of a second source device; a processing device configured to generate a third media data; and an output device configured to output media data. The media data may be the first media data, the second media data, or the third media data. The third media data affects the first media data or the second media data if the third media data and the first media data are simultaneously outputted, or the third media data and the second media data are simultaneously outputted. The processing device is configured to process the first media data and the second media data to obtain a processing result, the processing result being used to generate presentation data indicating correspondences between interfaces and the media data.
