Solution Overview

Problem

Existing electronic devices uniformly adjust video data, leading to excessive processing and poor display effects for videos of varying quality, compromising user experience.

Innovation Solution

An electronic device receives information from a server to adjust video quality based on the specific quality of the target video and its own capabilities, performing image processing to match these parameters, thereby optimizing display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If uniform adjustment is applied to all video data, then processing simplicity is improved, but display quality deteriorates due to excessive processing on already high-definition videos

Engineering Contradiction:
Improveprocessing simplicityVSAvoiddisplay quality
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies different processing intensities to different video data based on their inherent quality characteristics. High-definition videos receive minimal or no processing, while low-definition videos receive enhanced processing. This local differentiation resolves the contradiction by making processing quality-adaptive rather than uniform, improving display quality without complicating the overall processing framework.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent dynamically adjusts processing parameters based on the quality characteristics of input video data. By changing processing intensity parameters according to video definition levels, the system achieves both simplified processing for high-quality videos and enhanced processing for low-quality videos, resolving the contradiction between processing simplicity and display quality.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If no adjustment is applied to high-definition video data, then display quality is improved by avoiding excessive processing, but processing uniformity deteriorates

Engineering Contradiction:
Improvedisplay qualityVSAvoidprocessing uniformity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent introduces dynamic processing that adapts to the quality characteristics of input video data. The processing system automatically adjusts its behavior based on whether the input is high-definition or low-definition video, making the processing uniformity flexible rather than rigid. This dynamic approach maintains display quality by avoiding unnecessary processing of high-definition videos while preserving operational simplicity through automated quality-based routing.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If enhanced processing is applied to all video data, then display quality is improved for low-definition videos, but excessive processing occurs on high-definition videos leading to quality degradation

Engineering Contradiction:
Improvedisplay qualityVSAvoidexcessive processing damage
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies the principle of partial action by providing enhanced processing only where needed (low-definition videos) and minimal or no processing where sufficient (high-definition videos). This selective application of processing power improves display quality for videos that need it while avoiding the harmful effects of excessive processing on videos that already have high quality, thus resolving the contradiction between improving display quality and preventing processing damage.

Inventive Principle:
Principle #16Partial or excessive action
