Solution Overview

Problem

High-resolution video data files require longer times for transmission and processing due to increased file sizes, leading to undesirable delays in broadcasting and file operations.

Innovation Solution

The method involves splitting each frame of video data into partial resolution layers, with a base frame layer and additional layers transmitted based on priority information, allowing for adaptive frame rates and resolution adjustments to optimize transmission efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If high-resolution video data is transmitted without splitting, then video quality is maintained, but transmission time increases significantly

Engineering Contradiction:
Improvevideo resolutionVSAvoidtransmission time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent divides each video frame into multiple partial resolution layers (base layer and additional layers). The base layer contains essential low-resolution information that can be transmitted quickly, while additional layers contain incremental high-resolution details. This segmentation allows progressive transmission where the receiver can reconstruct video at different quality levels based on available bandwidth and time, resolving the contradiction between maintaining high resolution and reducing transmission time.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If complete video files are broadcast for file modification operations, then editing capabilities are enabled, but processing time increases

Engineering Contradiction:
Improvefile modification capabilityVSAvoidprocessing time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent performs preliminary processing by splitting video frames into hierarchical resolution layers before transmission. This preliminary action enables the receiver to access and modify specific layers (such as the base layer) without waiting for or processing the complete high-resolution video file. Users can perform file modification operations on lower-resolution representations more quickly, reducing processing time while maintaining the capability to edit video content.

Inventive Principle:
Principle #10Preliminary action

3Speed

If additional frame layers are transmitted at higher frame rates, then video smoothness is improved, but data transmission volume increases

Engineering Contradiction:
Improveframe rateVSAvoiddata transmission volume
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The patent applies different frame rates to different resolution layers based on their specific requirements. The base layer, which provides the essential video content, can be transmitted at a lower frame rate. Additional layers that enhance detail and smoothness can be transmitted at higher frame rates, but only where and when needed. This local quality approach optimizes the balance between video smoothness and data transmission volume by allocating bandwidth differentially across layers rather than uniformly.

Inventive Principle:
Principle #3Local quality
