Scaler IC Multi-Picture Processing Single Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require multiple cables for multi-picture processing, occupying space and necessitating manual resolution adjustments, and often display multiple screen settings options when in multi-picture processing mode is disabled.
Innovation Solution
A scaler IC with control signal, video input/output terminals, and EDID circuits that enables multi-picture processing using a single cable by analyzing MST video streams to generate SST streams for combined display, automatically adjusting resolution, and managing EDID to simplify screen settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cables are used to connect video source devices to the monitor for multi-picture processing, then multiple pictures can be displayed simultaneously, but the cables occupy limited space and cause inconvenience to the user
Solution Approach 1:
The patent merges multiple video input functions into a single cable connection by implementing a scaler IC that can process multiple picture streams through one DisplayPort interface. The scaler IC combines the functionality of multiple video inputs, allowing the monitor to display multiple pictures simultaneously while using only one physical cable connection between the video source device and the monitor.
2Adaptability or versatility
If the monitor displays multiple pictures in multi-picture processing mode, then the user can view multiple video sources, but the monitor cannot automatically adjust the resolution and the user needs to manually adjust through setting mechanisms
Solution Approach 1:
The scaler IC automatically performs resolution adjustment and picture parameter optimization without requiring user intervention. The control circuit within the scaler IC detects the input video signals, automatically adjusts resolution parameters, and optimizes display settings for multiple pictures, eliminating the need for users to manually configure resolution through operating system settings or monitor menus.
3Adaptability or versatility
If multiple video output ports are used on a single video source device, then multiple pictures can be displayed, but multiple sets of screen setting options appear in the setting mechanism when multi-picture processing mode is disabled
Solution Approach 1:
The scaler IC provides universal multi-functionality by handling multiple video input streams through a single interface. The device can operate in different modes (single picture, multi-picture, picture-in-picture) while maintaining a unified control interface. This eliminates the need for multiple separate screen setting options because the scaler IC manages all video processing functions through one integrated control system.
Data Source
AI summary
A scaler integrated circuit (IC) applicable to performing multi-picture processing in a display device includes multiple terminals, multiple Extended Display Identification Data (EDID) circuits and a control circuit. The control circuit receives a Multi-Stream Transport (MST) video stream from a video source through a first video input terminal, analyzes the MST video stream to generate a first Single Stream Transport (SST) video stream and a second SST video stream, sends the second SST video stream through a video output terminal to be a video output signal, and receives the video output signal through a second video input terminal, to allow the scaler IC to generate a combination picture according to the first SST video stream and the second SST video stream, for being displayed by a display output module within the display device.
