Solution Overview

Problem

Existing video transmission technologies face limitations in transmitting multiple kinds of interpolation data due to bandwidth constraints, such as those found in HDMI, making it impractical to achieve high image quality across all aspects like frame rate and resolution simultaneously.

Innovation Solution

An interpolation data selection unit prioritizes and selects specific interpolation data to be transmitted based on encoded information, optimizing data transmission to ensure high image quality while considering the capacity of the transmission line.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If all interpolation data of multiple kinds are transmitted to achieve high image quality, then image quality is improved, but transmission line capacity is exceeded

Engineering Contradiction:
Improveimage qualityVSAvoiddata transmission volume
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent extracts and transmits only the most essential interpolation data (motion compensation data) from the complete set of available interpolation data, separating critical data from optional data to fit within transmission constraints while maintaining core image quality

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different transmission strategies to different types of interpolation data based on their importance - motion compensation data is transmitted with high priority while other enhancement data may be omitted or transmitted with lower priority, creating localized quality optimization

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If multiple kinds of interpolation data are transmitted, then higher resolution and frame rate can be achieved, but transmission bandwidth is insufficient

Engineering Contradiction:
Improvevideo resolution and frame rateVSAvoiddata transmission speed
Core Design Contradiction:
Manufacturing precisionVSSpeed

Solution Approach 1:

The patent segments interpolation data into distinct categories (motion compensation, resolution enhancement, frame rate enhancement) and transmits them separately with different priorities, allowing the system to select and transmit only the segments that fit within bandwidth constraints

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If all available interpolation data are transmitted, then comprehensive image enhancement is achieved, but transmission time increases

Engineering Contradiction:
Improveimage qualityVSAvoidtransmission time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent transmits only the necessary portion of interpolation data (motion compensation data) required to achieve acceptable image quality, rather than transmitting all available enhancement data, thereby reducing transmission time while maintaining functional image quality

Inventive Principle:
Principle #16Partial or excessive action
