Solution Overview

Problem

In long-distance image transmission, it is difficult for the user at the transmitting end to confirm whether the transmitted image is correctly received by the receiving end, especially in scenarios like remote conferencing or video walls where multiple partial images are displayed.

Innovation Solution

A system and method that generates a reference image stream with reduced data amount compared to the target image stream, allowing the transmitting end to verify correct image display by comparing the reference image with the target image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If image data is transmitted over long distance, then the image can be displayed at remote locations, but it becomes difficult to confirm whether the transmitted image is correctly received

Engineering Contradiction:
Improvetransmission distanceVSAvoidimage reception confirmation
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the receiving device sends back received image data to the transmitting device. This allows the transmitting device to compare the original image data with the received image data and determine whether the image was correctly received, thus resolving the reliability issue in long-distance transmission.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent uses visual indicators (such as color changes or visual cues) to indicate the status of image transmission and reception. These visual indicators provide immediate feedback to users about whether the image transmission was successful, making the confirmation process intuitive and reliable.

Inventive Principle:
Principle #32Color changes

2Quantity of substance

If reference image data with reduced data amount is generated, then bandwidth consumption is reduced, but image detail information is lost

Engineering Contradiction:
Improvedata amountVSAvoidimage detail information
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

The patent segments image data into different components (such as key information and detailed information). The reference image contains key information with reduced data amount for efficient transmission, while the original image retains all detailed information. This segmentation allows both bandwidth efficiency and information preservation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different quality levels to different parts of the image transmission process. The reference image uses reduced quality (lower data amount) for areas that don't require high detail, while critical areas maintain higher quality. This local quality approach balances data reduction with information preservation.

Inventive Principle:
Principle #3Local quality

AI summary

An image data transceiving system (100), including: a transmitting device (101), configured to output a first target image stream (TIS_1) including a plurality of first target images (I_T1); and a receiving device (103), configured to decode the first target image stream (TIS_1) to obtain a plurality of second target images (I_T2). A reference image stream (RIS) is generated according to the first target image stream (TIS_1), and includes first reference images (I_R1) generated by the transmitting device (101) or second reference images (I_R2) generated by the receiving device (103). Data amount of a first reference image (I_R1) is less than that of a corresponding first target image (I_T1), and data amount of a second reference image (I_R2) is less than that of a corresponding second target image (I_T2). The transmitting device (101) receives the reference image stream (RIS) through the receiving device (103).
