Multivideo Display System Using Periodic Frame Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multivideo display systems, such as PIP and double picture methods, compromise on resolution and cause image distortion or obstruction when displaying multiple video images simultaneously, failing to provide a clear and unobstructed view of full-screen video images.
Innovation Solution
A system comprising a video processor that alternately outputs first and second images based on frame similarity, using a display panel and backlight unit to prevent image blurring and maintain resolution, allowing for the simultaneous display of multiple video images without overlapping or distortion, and optionally supporting 3D image display based on user selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If PIP method is used to display multiple video images, then multiple video images can be displayed simultaneously, but the main screen region is covered and hidden by the sub-screen
Solution Approach 1:
The patent applies periodic action by alternately displaying first and second video images at different time periods. The video processor switches between displaying the first video image and the second video image in a periodic manner, allowing each image to occupy the full screen at its designated time without overlapping or obscuring the other, thus resolving the contradiction between displaying multiple images and maintaining full screen visibility.
2Quantity of substance
If double picture method is used to display multiple video images, then multiple video images can be displayed simultaneously, but the horizontal size of video image is decreased causing vertical extension and distortion
Solution Approach 1:
The patent uses periodic action to alternately display multiple video images in full-screen mode. By switching between images at different time periods rather than displaying them simultaneously in reduced size, each image maintains its original horizontal and vertical dimensions, preventing distortion and preserving image quality while still allowing multiple images to be viewed sequentially.
3Quantity of substance
If multiple video images are displayed simultaneously using conventional methods, then users can view multiple images, but image overlapping and blurring occur
Solution Approach 1:
The patent eliminates image overlapping and blurring by implementing periodic action where only one video image is displayed at a time. The video processor alternates between different video images in a periodic sequence, ensuring that each image is displayed clearly without superposition with other images, thus maintaining high image clarity and focus while still enabling users to view multiple video sources.
4Duration of action of moving object
If video images are displayed continuously without frame-based control, then smooth video playback is achieved, but power consumption increases
Solution Approach 1:
The patent applies periodic action by controlling the video processor to operate in a periodic frame-based manner rather than continuous operation. The processor alternates between displaying different video images at specific frame intervals, allowing the display system to enter low-power states between active display periods, thus reducing overall power consumption while maintaining the illusion of continuous video playback through rapid periodic switching.

AI summary
A system is discussed for displaying multivideo, which enables users to view a plurality of different video images at the same time through one video displaying system without lowering resolution. The system includes according to an embodiment a video processor for alternately outputting first and second images every predetermined number of frames according to a similarity between previous and present frames of first or second video image; and a display panel for displaying the video image outputted from the video processor.
