Data Transmission Method with Embedded Clock Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission methods require separate lines for clock signals, leading to increased complexity, manufacturing costs, and electromagnetic interference (EMI), as well as potential errors due to skew between data and clock signals.
Innovation Solution
A method that forms transmission preparatory packets, transition inducing packets, and transition included data packets, allowing data to be transmitted with embedded clock information, eliminating the need for separate clock lines and reducing EMI by performing logical operations to create transition included data packets for efficient data transmission and restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate lines are used to transmit clock signals from the timing control unit to data driving units, then clock signals can be transmitted reliably, but the wiring complexity increases and manufacturing costs increase
Solution Approach 1:
The patent combines clock signal transmission with data signal transmission by multiplexing them onto the same transmission line. The timing control unit transmits both clock information and data information through a single line to the data driving unit, eliminating the need for separate clock lines and reducing wiring complexity while maintaining reliable clock signal delivery
Solution Approach 2:
The transmission line is designed to serve multiple functions simultaneously - it carries both clock signals and data signals. The data driving unit is capable of receiving and processing both types of information from the same line, making the transmission system more efficient and reducing the overall number of required transmission lines
2Adaptability or versatility
If separate lines are used to transmit clock signals, then clock signals can be transmitted independently, but the number of signal lines increases
Solution Approach 1:
The patent merges clock signal transmission and data signal transmission into a single transmission line. The timing control unit multiplexes clock information and data information onto one line, allowing both signals to be transmitted simultaneously without requiring separate dedicated lines for each signal type
3Speed
If high frequency clock signals are transmitted through separate lines, then clock signals can be delivered with sufficient speed, but electromagnetic interference increases
Solution Approach 1:
The patent combines clock and data signals on the same transmission line, which allows for better signal shielding and reduced electromagnetic interference. By transmitting both signals together through a single line, the system can maintain high frequency operation while the combined signal structure reduces EMI compared to separate high-frequency clock lines
4Device complexity
If separate lines are used for clock and data signals, then signal transmission can be simplified, but skew between signals occurs causing sampling errors
Solution Approach 1:
The patent transmits both clock signals and data signals through the same transmission line, which eliminates skew between the signals since they travel together through the same path. This ensures that the clock and data signals arrive at the data driving unit with proper synchronization, preventing sampling errors while maintaining transmission simplicity

AI summary
Disclosed are a data transmission method and a data restoration method. The data transmission method includes forming a plurality of transmission preparatory packets by dividing data to be transmitted by the predetermined number (n) of bits, forming transition inducing packets different from the transmission preparatory packets while having the predetermined number (n) of bits, forming transition included data packets by performing a logical operation on the transition inducing packet and each of the transmission preparatory packets, and transmitting the transition included data packets and the transition inducing packet.
