Custom Video Stream Display Format via Graphic Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display technologies fail to provide users with an intuitive and effective method to customize video stream display formats, particularly when dealing with varying aspect ratios and unwanted bands, leading to unsatisfactory user experiences due to inaccurate format detection and complex resizing processes.
Innovation Solution
A method that allows users to define a video stream display format by superimposing a graphic element, such as a rectangle, on the screen to select and resize the area of interest, enabling intuitive customization of the display format, with options to store and recall settings for future use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic resizing methods analyze the active content of the video stream to autonomously change the display mode, then the device can automatically adapt to different video formats, but the algorithm cannot correctly detect and identify areas containing information of interest, leading to inaccurate resizing operations
Solution Approach 1:
The patent introduces a graphic element (rectangle) as an intermediary tool that the user manipulates to define the area of interest. This graphic element serves as a mediator between the user's viewing preferences and the video stream, allowing precise selection of content to be displayed without relying on inaccurate automatic detection algorithms.
Solution Approach 2:
The system allows users to directly control the display format by manually adjusting the graphic element on the screen. This self-service approach empowers users to define their own viewing preferences without relying on potentially inaccurate automatic detection, giving them direct control over which parts of the video stream are displayed.
2Adaptability or versatility
If factory predefined display formats are used, then the device can provide standard resizing options, but the options cannot cover the preferences of all users with different tastes
Solution Approach 1:
The patent transforms the static predefined display formats into a dynamic customization system. Instead of being limited to fixed factory settings, users can dynamically adjust the graphic element to create custom display formats that adapt to their personal preferences. This dynamic approach allows unlimited customization possibilities while maintaining ease of operation through simple screen interactions.
3Ease of operation
If a special configuration procedure is used to define customised display mode, then the device can provide user-defined display formats, but the procedure is time-consuming, complex and not very intuitive
Solution Approach 1:
The patent performs the display format definition action directly during normal video viewing by superimposing a graphic element on the current frame. This preliminary action allows users to define their preferred display format while watching the video, eliminating the need for separate configuration procedures and saving time.
Solution Approach 2:
The system copies the current video frame and superimposes a graphic element on it, allowing users to visually interact with a representation of the display format. This copying approach makes the abstract configuration process concrete and intuitive, as users can directly manipulate the graphic element on the screen rather than navigating complex menu structures.
4Reliability
If bands containing advertisements or auxiliary dynamic contents are displayed, then the original video stream format is preserved, but the bands occupy a large portion of the screen space and may be annoying for the spectator
Solution Approach 1:
The patent allows users to extract and isolate the area of interest from the entire video frame by defining a custom region using the graphic element. This extraction enables users to display only the relevant content while excluding unwanted bands and advertisements, giving them control over what occupies screen space while preserving the original video stream integrity.

AI summary
The present invention relates to a method for displaying a video stream according to a format defined by a user, wherein a graphic element is superimposed on the displayed video stream, and wherein the dimensions and/or position of the graphic element are modified as a function of commands received from the user, so as to define a screen area in which a certain portion of the frames of the video stream is displayed. The video stream is then displayed in a format wherein, for each frame, the frame portion defined by the graphic element is displayed with altered dimensions and/or position on the screen.
