Substitution Display Memory for Missing Video Input Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to determine what media data should be inputted into a video processing system when certain input sources are not providing normal media data, as existing systems display a 'no-signal' screen without clear indication of the required content.
Innovation Solution
A video processing device and method that includes a substitution display memory storing images or videos representing the content that should be inputted for each input terminal, which are displayed in place of the missing media data, allowing users to easily identify the necessary input for each source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a no-signal screen is displayed to indicate missing media data, then the user can identify that media data is not normally inputted, but the user cannot learn what video should be inputted to the input channel
Solution Approach 1:
The patent stores substitution display data (images or videos representing the content that should be inputted) in a substitution display memory for each input terminal. When media data is not normally inputted, the processor displays the corresponding substitution display data from memory instead of a generic no-signal screen, allowing users to identify both the input channel status and the required content type.
2Ease of operation
If a generic no-signal screen is displayed for all input channels, then the device complexity is reduced, but the user experience deteriorates due to lack of specific guidance
Solution Approach 1:
The patent pre-stores substitution display data in the substitution display memory for each input terminal before actual operation. This preliminary preparation allows the system to quickly retrieve and display appropriate substitution content when media data is missing, improving user experience without requiring complex real-time analysis or processing during operation.
Data Source
AI summary
A video processing device outputting a composite video in which multiple media data are arranged includes an input terminal, a substitution display memory, and at least one processor. The substitution display memory stores substitution display data for each one of the input terminal. The substitution display data is composed of an image or a video representing a content of the media data that should be inputted in the input terminal. The at least one processor is configured to determine whether the media data has been normally inputted in the input terminal, and acquire the substitution display data corresponding to the input terminal from the substitution display memory and display, in the composite video, the substitution display data acquired corresponding to the input terminal in place of the media data from the input terminal, upon determining that the media data has not been normally inputted in the input terminal.
