Solution Overview

Problem

Conventional methods for distributing video imagery to pervasive devices over computer networks inefficiently consume resources due to repeated compression and subsequent resizing, especially when dealing with a large number of devices, as they do not account for the target device's display size before compression.

Innovation Solution

A method and system for pre-distribution image scaling, where video imagery is scaled to match the target device's display size before compression, optimizing resource usage by eliminating unnecessary processing steps and reducing resource consumption during transmission and decompression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If video imagery is compressed before transmission to pervasive devices, then the bandwidth utilization is improved, but computational resources are needlessly consumed on aspects that will not survive subsequent scaling

Engineering Contradiction:
Improvebandwidth utilizationVSAvoidcomputational resources
Core Design Contradiction:
Loss of energyVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by determining the target display size before compression and pre-scaling the video imagery to match that display size. This ensures that compression operates only on the necessary pixel data, eliminating waste of computational resources on pixels that would be scaled down anyway, while still achieving efficient bandwidth utilization through compression.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If video imagery is compressed without considering target display size, then compression can be applied uniformly, but resources are wasted compressing pixels that will be scaled down

Engineering Contradiction:
Improvecompression processVSAvoidcomputational resources
Core Design Contradiction:
Ease of manufactureVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by adapting the compression process to the specific characteristics of the target device's display size. Instead of uniform compression across all images, the system determines the target display dimensions and scales the imagery locally to match before compression, ensuring computational resources are focused only on the relevant pixel data for each target device.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If video imagery is scaled after compression on the pervasive device, then the target device can handle the resizing, but additional process resources are consumed on the pervasive device

Engineering Contradiction:
Improveflexibility in processingVSAvoidprocess resources on pervasive device
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by performing the scaling operation before compression and transmission, rather than after decompression on the pervasive device. This shifts the computational burden to the server side where resources are more abundant, and eliminates the need for the pervasive device to consume additional process resources on resizing operations.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If video imagery is compressed at full resolution, then compression can be applied to all pixels, but bandwidth is wasted transmitting pixels that will be scaled down

Engineering Contradiction:
Improvecompression completenessVSAvoidbandwidth
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies local quality by matching the compression resolution to the target display size. The system determines the dimensions of the target device's display and scales the video imagery to those dimensions before compression, ensuring that compression is applied only to the necessary pixel data. This eliminates bandwidth waste from transmitting excess pixels that would be scaled down, while maintaining complete compression coverage for the relevant image area.

Inventive Principle:
Principle #3Local quality
