BINARY DATA TRANSMISSION METHOD |
摘要 |
PURPOSE:To realize the highly efficient transmission of a large quantity of binary data by replacing the binary data corresponding to the control codes with other binary data having the lower emerging frequency and converting it into the 2-byte data for transmission. CONSTITUTION:A frequency distribution of the transmission data 1 is first obtained and (n) pieces of binary data corresponding to (n) pieces of control codes are selected out of the emerging frequency having the smallest emerging rate. It is decided whether these selected data are equal to the control codes or not. Then the numbers and types of the control codes are stored in a matrix C(m) and the binary data excluding (p) pieces of control codes are stored in a matrix D(p) together with (p) pieces of control codes stored in a matrix E(p) respectively. A data conversion table 2 is produced with these matrices and the transmission data 3 is obtained through conversion. In this case, the binary data corresponding to the control codes are converted into the 2-byte binary data.
