AV Input Source Labeling via On-Screen Menu Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of display devices, such as televisions, face difficulties in identifying and switching between external AV input sources without sequentially selecting options using a remote control, as they cannot directly determine which external device is connected to a specific input terminal.
Innovation Solution
A display device with a controller that displays a menu for labeling AV input sources on the screen, allowing users to select and store representative identifications, including manufacturer, serial number, and data format, along with a signal processor to convert signals into displayable formats, enabling easy identification and selection of input sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the television provides multiple external input terminals for receiving various inputs, then the adaptability and versatility of the television is improved, but the ease of operation deteriorates because users cannot directly identify which external device is connected to which input terminal
Solution Approach 1:
The patent introduces an intermediary labeling system that displays external device information on the television screen. This mediator bridges the gap between the input terminals and external devices, allowing users to identify which device is connected to which terminal without physically checking connections or sequentially testing each input source.
2Ease of operation
If users must sequentially select input sources using a remote control to find the desirable source, then the ease of operation deteriorates, but the time required to identify and switch to the correct input source increases
Solution Approach 1:
The patent implements preliminary action by pre-displaying the labels of external devices on the television screen before the user needs to switch input sources. This allows users to immediately identify the correct input terminal without having to sequentially test each one, significantly reducing the time and effort required to switch between devices.
3Device complexity
If the television displays only the image from the selected input source, then the simplicity of the display is maintained, but the loss of information increases because users cannot see which external device is connected
Solution Approach 1:
The patent adds another dimension to the display by superimposing label information onto the video image. This dimensional enhancement allows users to see both the visual content from the selected input source and the identification information about which external device is connected, without requiring a separate display interface.
Data Source
AI summary
A display device and a method for labeling input sources are disclosed, to set and provide label information of the input sources on a screen of the display device, for a user's convenience, in which the display device includes a plurality of input terminals respectively connected to a plurality of input sources, a controller configured to display a menu of setting label information of the input sources on a screen, and to display the corresponding label information along with an image of the input source selected by a user; and a memory configured to store the received label information of the input sources.
