Video Processing Apparatus Picture-in-Picture Single Stream
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing systems are limited to multi-window displays and cannot effectively show multiple moving bodies on a single screen without restricting the number of screens, making them unsuitable for single-window displays.
Innovation Solution
A video processing apparatus that detects multiple moving bodies, determines a main and sub moving body, and generates a picture-in-picture synthesized video, allowing multiple moving bodies to be displayed on one screen by superimposing sub videos at determined positions within the main video, outputting the combined video in a single stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-window display system is used to display multiple moving bodies, then the number of moving bodies that can be displayed is limited only by the number of screens, but the system complexity increases due to requiring multi-stream transmission and multiple monitors
Solution Approach 1:
The patent merges multiple video streams into a single stream by superimposing multiple moving body videos onto one another in a picture-in-picture manner. This combining approach allows multiple moving bodies to be displayed simultaneously while transmitting only one video stream, thereby reducing system complexity while maintaining display versatility
Solution Approach 2:
The patent implements a nested display structure where multiple sub-video windows containing different moving bodies are embedded within a main video window. This nesting arrangement enables multiple moving bodies to be displayed in a hierarchical manner on a single screen or stream, achieving multi-display capability without requiring multiple independent streams or screens
2Adaptability or versatility
If a multi-window display is implemented to show multiple moving bodies, then more moving bodies can be displayed, but the system cannot be applied to single-window display systems
Solution Approach 1:
The patent creates a universal video processing system that can operate in both multi-window and single-window display modes. By superimposing multiple moving body videos within a single stream using picture-in-picture technology, the system maintains compatibility with single-window display systems while still enabling the display of multiple moving bodies, thus achieving multi-functionality
3Quantity of substance
If multiple screens are used to display multiple moving bodies, then all moving bodies can be displayed, but the system requires multiple monitors and cannot work with a single screen
Solution Approach 1:
The patent transitions from a spatial distribution approach (multiple screens side by side) to a temporal/superposition approach (multiple videos layered in time and space within one stream). By using picture-in-picture superimposition, multiple moving bodies are displayed simultaneously within a single screen by utilizing different spatial dimensions within the same display area, eliminating the need for multiple physical screens

AI summary
A video processing apparatus analyzes an input video input from a video input unit, detects a plurality of moving bodies included in the input video, determines a main moving body and a sub moving body, and determines a sub picture position for superimposing and displaying a sub video in a main video in a picture-in-picture form. This video processing apparatus performs cut-out processing on the main video and the sub video from the input video, and synthesizes the cut-out main video and sub video to generate a picture-in-picture synthesized video in which the sub video is superimposed at the sub picture position of the main video in the picture-in-picture form. The picture-in-picture synthesized video is output in one stream.
