Video Format Converter for Low-Resolution Video Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-resolution videos, often with compression artifacts, become unacceptably poor in quality when displayed on large-screen devices due to inadequate processing techniques, which struggle to handle the difference between higher-resolution and lower-resolution content effectively.
Innovation Solution
A video format converter is used to detect the true resolution of low-resolution videos and apply appropriate deinterlacing and noise reduction techniques, enhancing the video signal to improve visual quality before processing by large-screen devices, thereby avoiding unsuitable deinterlacing circuitry and addressing artifacts like blocking and mosquito noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If low-resolution video is displayed directly on large-screen devices, then the display resolution matches the screen capability, but the picture quality becomes unacceptably poor
Solution Approach 1:
The patent applies preliminary deinterlacing and noise reduction processing to low-resolution video content before it is displayed on large-screen devices. By performing these processing steps in advance through the video format converter, the system prepares the video signal to accommodate both the lower source resolution and the higher display resolution, preventing quality degradation while maintaining compatibility across different display devices.
2Ease of operation
If complex deinterlacing techniques are applied to low-resolution video, then interlaced video can be displayed on progressive displays, but the processing may worsen the presentation of low-resolution video
Solution Approach 1:
The patent implements different deinterlacing strategies based on the specific characteristics of the video content and display device. Rather than applying a uniform complex deinterlacing process to all videos, the system selectively applies appropriate processing techniques tailored to each video's resolution and quality characteristics, thereby maintaining display compatibility while avoiding quality degradation from overly aggressive processing.
3Quantity of substance
If video compression is used to reduce file size for portable devices, then storage and transmission efficiency improves, but compression artifacts such as blocking and mosquito noise are introduced
Solution Approach 1:
The patent converts the harmful compression artifacts into beneficial visual characteristics by applying noise reduction processing that specifically targets and reduces blocking artifacts and mosquito noise while preserving or enhancing legitimate video content. This transforms the degraded quality caused by compression into an improved visual experience through selective artifact removal and quality enhancement.

AI summary
Systems and methods are provided for improving the visual quality of low-resolution video displayed on large-screen displays. A video format converter may be used to process a low-resolution video signal from a media providing device before the video is displayed. The video format converter may detect the true resolution of the video and deinterlace the video signal accordingly. For low-resolution videos that are also low in quality, the video format converter may reduce compression artifacts and apply techniques to enhance the appearance of the video.
