Data Transceiver System Using Differential Encoding to Eliminate Overhead Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transceiver systems for display devices require overhead data to encode image data into clock embedded data, which increases memory requirements and latency.
Innovation Solution
A data transceiver system that encodes image data by generating an edge without overhead data, using an encoder that performs logical operations based on a random number and image data, and inverts the encoded data every N bits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If overhead data is added to image data to encode to clock embedded data, then encoding can be achieved, but memory requirements and latency increase
Solution Approach 1:
The patent extracts and eliminates the overhead data component from the encoding process. Instead of adding overhead data to image data for encoding, the invention uses a differential encoding method that directly encodes image data by generating edges without requiring any overhead data, thereby removing the source of increased memory requirements and latency
Solution Approach 2:
The patent changes the encoding parameter from conventional methods that require overhead data to a differential encoding approach. The encoder generates first encoded data by performing logical operations based on random number and image data, then generates second encoded data by inverting the first encoded data every N bits, creating edges without requiring overhead data addition

AI summary
A data transceiver system includes an encoder which generates first encoded data by performing a logical operation based on a random number and image data, and generates second encoded data by inverting the first encoded data every N bits, where N is a positive integer greater than or equal to 2, and a decoder which restores the first encoded data by decoding the second encoded data, and restores the image data by decoding the first encoded data.
