Video Tiling Gesture Control Matrix Switcher
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing systems are difficult to control and have limitations in displaying multiple video streams simultaneously, making it cumbersome for users to navigate and manage large collections of video content.
Innovation Solution
A video tiling system that uses a matrix switcher/controller and multi-window video processing output modules in a daisy chain arrangement, coupled with a wireless mobile device interface for intuitive gesture-based control, allowing for scalable and customizable tiled video displays with nested tiles, enabling users to easily manage and view numerous video streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a graphical user interface is used to control video windows, then the user can select and manipulate video windows, but the navigation becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical pointing device interface (mouse, remote control) with a direct touch interface on the display screen itself. Users can directly touch and drag video windows to resize and reposition them, eliminating the need for cumbersome navigation through graphical menus and the precision requirements of pointing devices. This direct manipulation approach significantly reduces navigation time and improves ease of operation.
2Adaptability or versatility
If a fixed maximum number of video streams is displayed simultaneously, then the system is simple to implement, but the system cannot handle large collections of video content
Solution Approach 1:
The patent implements a tiled display system where the screen is divided into multiple independent video window regions that can be dynamically created, resized, and arranged. Instead of being limited to a fixed number of video streams, the system allows users to create as many video windows as needed by dragging and dropping the window edges. Each video window can be independently controlled and positioned, enabling the display of large collections of video content without significantly increasing system complexity.
3Device complexity
If physical selection buttons are used to control video windows, then the system is simple in structure, but it is difficult for users to remember button functions and operations
Solution Approach 1:
The patent replaces physical selection buttons and button-centric remote controls with direct touch manipulation of video windows on the display screen. Users can directly touch, drag, and resize video windows to perform operations, eliminating the need to remember which buttons correspond to which windows or operations. This direct manipulation interface makes the system intuitive and easy to control while maintaining relatively simple system structure.

AI summary
In one embodiment, a tiled video display is shown on a screen of a display device. The tiled video display includes a plurality of video tiles that each show video content of a different video stream. The video tiles are arranged on the screen according to a tiling layout. A user interface (UI) is shown on a touch sensitive screen of a wireless mobile device separate from the display device. The UI includes a plurality of UI tiles that each correspond to a respective video tile of the tiled video display. The UI tiles are arranged on the virtual display screen according to the tiling layout of the video tiles. In response to a gesture over at least a portion of a particular one of the UI tiles on the touch sensitive screen, a modification is made to both the particular UI tile and a correspond video tile.
