PURPOSE:To restore a compression data in a short time by replacing a code string being compression object into a 1-byte control code and adding a 1-byte control code before a code representing non-compression object so as to record the result. CONSTITUTION:In taking 0s or spaces only consecutive for >=3bytes as a compression object, a control code 17 comprising 00 representing a non-compression object and a figure 2 representing a byte number are added to head 2-byte AB of a digital code string 11 and the result is recorded. Since the next code string 13 is a compression object, the string is replaced into a control code 19 comprised of 10 representing the compression of consecutive 0s and a figure 3 representing its byte number and the result is recorded. The final code string 15 is replaced into a control code 22 consisting of 01 representing the compression of consecutive spaces and of figure 4 representing the byte number and the result is recorded. The data compressed in this way is restored very easily in a short time. |
