Remote Image Stream Verification Using Reference Image Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image data transceiving systems struggle to confirm whether transmitted images are correctly received, especially in long-distance transmissions, making it difficult for users to verify the display of images on remote devices or video walls.
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 images with the target images.

1Length of moving object
If image data is transmitted over long distance, then the image can be displayed on remote devices, but it becomes difficult to confirm whether the transmitted image is correctly received
Solution Approach 1:
The patent implements a feedback mechanism where the receiving device sends back a reference image stream to the transmitting device. This reference image stream contains reference images that correspond to the transmitted target images, allowing the transmitting device to verify whether the images were correctly received and displayed at the remote location.
Solution Approach 2:
The patent creates reference images that are copies or representations of the original target images. These reference images are included in the reference image stream sent back to the transmitting device, enabling verification without requiring the transmitting device to physically view the displayed images at the remote location.
2Measurement precision
If reference images with full data amount are transmitted back for verification, then accurate verification is achieved, but transmission bandwidth and time are consumed
Solution Approach 1:
The patent changes the parameters of the reference images by reducing their data amount through compression or downsampling while maintaining the essential visual information needed for verification. This allows the reference images to be sufficiently accurate for verification purposes while consuming less bandwidth and transmission time.
Solution Approach 2:
The patent applies partial action by transmitting only the necessary portion of image data for verification. The reference images contain sufficient information to verify correct reception but exclude redundant data, achieving verification accuracy without the overhead of transmitting complete-quality reference images.

AI summary
An image data transceiving system, comprising: a transmitting device, configured to output a first target image stream, wherein the first target image stream comprises a plurality of first target images; and a receiving device, configured to decode the first target image stream to obtain a plurality of second target images. The transmitting device or the receiving device generates a reference image stream according to the first target image stream. The reference image stream comprises first reference images generated by the transmitting device or second reference images generated by the receiving device. Data amount of the first reference images is less than data amount of corresponding ones of the first target images, and data amount of the second reference images is less than data amount of corresponding ones of the corresponding second target images. The transmitting device further receives the reference image stream through the receiving device.
