Signal transmission device and method, and signal reception device

A signal reception device, comprising:

• a receiving unit for receiving N second bit signals corresponding one of the transmission signals transmitted via N (an even integer greater than 2) signal lines;
• and
• a bit signal decoding unit for generating K (one or more integers) first bit signals corresponding to one of the original signals from the N second bit signals,
• wherein N/2 signal lines of the N signal lines transmit a second bit signal of a high voltage and remaining N/2 signal lines of the N signal lines transmit a second bit signal of a low voltage,
• the number of the original signals and the number of the transmission signals are the same and each of the original signals and each of the transmission signals are matched at 1:1, and
• the bit signal decoding unit generates the K first bit signals from the N second bit signals based on the 1:1 matching relationship between the original signal and the transmission signal.
