This paper develops the minimum scrambling source coding method on the basis of 8-bit symbol. The symbol is formed with upper (column) 4-bit sub-symbol and lower (row) 4-bit sub-symbol. This paper shows the combination method of upper sub-symbol and lower sub-symbol to make unscrambling symbols. This paper also presents the way how to make a minimum scrambling character source coding with the symbols. After the unscrambling and scrambling symbol is confirmed by the developed method, each character is coded by a symbol or symbols on the basis of probability of the character use frequency. A character that has high use frequency is given an unscrambling symbol(s) but a character that has low use frequency is coded a scrambling symbol(s). When the number of characters is equal to or less than the number of the unscrambling symbols, the scrambling in the line coder is not generated. But if the number of character is exceeded the number of the unscrambling symbols, the characters are coded based on a probability of the character use frequency. The developed method applies all kinds of source coding system that affects data transmission signal.
