Data Transmitter Encoding for Embedded Low-Speed State Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods either increase equipment costs by requiring separate transmission media for high-speed and low-speed data or reduce data transmission efficiency by using time-sharing techniques, especially when multiple types of data are transmitted through the same path.
Innovation Solution
A data transmitter and receiver system that encodes high-speed data using 8B10B encoding rules, incorporating low-speed data by altering the running disparity (RD) value, allowing low-speed data to be transmitted within the high-speed data stream without separate media or time-sharing, thus maintaining efficient data transmission.

Engineering Contradiction Analysis
1Reliability
If a separate transmission medium is provided for transmitting information about the state of the device, then information about the state of the device can be transmitted without blocking data transmission, but the equipment cost is increased
Solution Approach 1:
The patent combines state information transmission with data transmission by using the same transmission medium L1. The encoder modifies the encoding rules of high-speed data to embed low-speed state information, merging two separate transmission functions into one medium, thereby eliminating the need for a dedicated transmission medium and reducing equipment cost.
Solution Approach 2:
The transmission medium L1 is made multi-functional by enabling it to carry both high-speed data and low-speed state information simultaneously. The encoder modifies encoding rules to embed state information within the data stream, allowing the single medium to perform multiple transmission functions without requiring separate dedicated channels.
2Device complexity
If information about the state of the device is transmitted through a data transmission medium in a time-sharing manner, then equipment cost is reduced, but the transmission efficiency of high-speed data is reduced
Solution Approach 1:
The patent enables continuous transmission of high-speed data without time-sharing interruptions by embedding low-speed state information within the data stream through modified encoding rules. This approach maintains the continuity of data transmission while simultaneously conveying state information, eliminating the efficiency loss associated with time-sharing methods.
Solution Approach 2:
The encoder modifies the encoding rules (changing parameters) of high-speed data to embed low-speed state information. By altering the encoding scheme dynamically, the system can incorporate state information without disrupting the continuous flow of high-speed data, thereby maintaining transmission efficiency while reducing equipment complexity.
3Device complexity
If multiple pieces of data are transmitted through the same transmission path using time-sharing, then equipment cost is reduced, but transmission efficiency is reduced
Solution Approach 1:
The patent merges multiple data streams (high-speed data and low-speed state information) into a single transmission path by modifying encoding rules. This combination allows simultaneous transmission of multiple data types without time-sharing, eliminating time loss while using a single transmission medium, thus resolving the contradiction between equipment cost and transmission efficiency.
Solution Approach 2:
The patent embeds low-speed state information within the high-speed data stream by modifying encoding rules, effectively adding an information dimension within the existing data transmission framework. This approach allows multiple data types to coexist in the same transmission path without interfering with each other, avoiding time loss while maintaining equipment simplicity.

AI summary
A data transmitter includes an encoder configured to encode first data to be transmitted, in accordance with an encoding rule and a transmitter configured to transmit the encoded first data. The encoder makes a change to the encoding rule, encodes the first data in accordance with the change in the encoding rule, and incorporates second data having content corresponding to the change in the encoding rule, into the first data.
