Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Server-based computing applications face bandwidth limitations when transmitting large amounts of visual data, leading to potential interruptions and poor user experience due to limited network bandwidth, especially in interactive gaming and other visual content delivery scenarios.

Innovation Solution

Visual data is categorized into different categories based on sensitivity to the human eye, with more bandwidth allocated to motion-sensitive foreground content and less bandwidth to less sensitive background content, using frame rate throttling to optimize network utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If visual data is transmitted at high bandwidth to maintain visual quality, then user experience is improved, but network bandwidth consumption increases

Engineering Contradiction:

Improvevisual qualityVSAvoidnetwork bandwidth consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent segments visual data into multiple categories based on human eye sensitivity: foreground objects (high sensitivity), background objects (low sensitivity), and other elements. Each category is transmitted with appropriate bandwidth allocation, allowing critical visual information to maintain quality while reducing overall bandwidth consumption by applying different compression and transmission priorities to different segments of the visual data.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If all visual data is transmitted with equal priority, then visual completeness is maintained, but network efficiency decreases

Engineering Contradiction:

Improvevisual completenessVSAvoidnetwork efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The patent applies local quality by assigning different transmission priorities and quality levels to different regions of the visual display based on human eye sensitivity. Foreground objects that attract more visual attention receive higher transmission priority and better quality preservation, while background areas receive lower priority and higher compression. This ensures visual completeness for important elements while optimizing network efficiency through selective quality management.

Inventive Principle:

Principle #3Local quality

3Speed

If frame rate is increased for all visual content, then motion smoothness is improved, but bandwidth requirements increase

Engineering Contradiction:

Improveframe rateVSAvoidbandwidth requirements

Core Design Contradiction:

SpeedVSQuantity of substance

Solution Approach 1:

The patent implements dynamic frame rate adjustment based on content importance. Different categories of visual data are transmitted at different frame rates: foreground objects maintain higher frame rates for smooth motion perception, while background elements use lower frame rates. This dynamic differentiation allows motion smoothness for critical content without proportionally increasing overall bandwidth requirements.

AI summary

Disclosed is an approach for delivering visual content that improves network bandwidth utilizations. The visual data is separated into multiple categories, where the data for different categories are delivered using different bandwidth utilizations schemes. A first category of the data is delivered at a higher frame rate than the frame rate for a second category of the data.
