Image Transmission Apparatus Raster Division for 3G-SDI Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image transmission systems, such as those using the 3G-SDI format, are limited in transmitting image data beyond 4K resolution, making it difficult to transmit higher resolution RAW data effectively.
Innovation Solution
The system divides image data into multiple pieces, specifically into EVEN and ODD images, and allocates them across multiple transmission paths using a raster scanning direction, allowing for the transmission of higher resolution data compliant with the 3G-SDI standard by multiplexing pixel data across multiple data streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image data is transmitted using the 3G-SDI format, then transmission compliance is maintained, but resolution is limited to 4K or less
Solution Approach 1:
The image data is divided into multiple pieces (first image data and second image data) along the raster scanning direction, allowing high-resolution data to be split into transmittable segments that comply with 3G-SDI format while preserving the original high resolution
Solution Approach 2:
Multiple transmission paths are utilized to transmit the divided image data simultaneously, effectively increasing the transmission bandwidth dimension and enabling high-resolution data transmission through parallel channels
2Measurement precision
If image data is divided into multiple pieces for transmission, then higher resolution transmission is enabled, but transmission path complexity increases
Solution Approach 1:
The image data is systematically divided into sequential segments (first and second image data) along the raster scanning direction, creating a structured transmission approach that manages complexity through organized segmentation
Solution Approach 2:
The image data is pre-divided into multiple pieces before transmission, with allocation to different transmission paths determined in advance, simplifying the transmission process by preparing the data structure beforehand

AI summary
When image data having a size larger than a size transmittable in a predetermined format is to be transmitted, an image transmission apparatus divides the image data in a raster scanning direction in a unit of a predetermined number of pixels and sequentially allocates the image data of the unit of a predetermined number of pixels to a plurality of divided images in an order of the raster scanning direction to divide the image data into the plurality of divided images, and outputs the plurality of divided images through a plurality of transmission paths.
