Title: Data compression
Inventor: HUMBLET PIERRE A
IPC: H03M7/42
Filed: 1985-01-30
Abstract: A stream of source characters having a time-varying frequence of appearance has the characters ranked in order of their current relative frequency of appearance. The codewords belong either to a first, second or third group of codewords, comprising respectively one, two or three equal length subwords. Each character having a rank not higher than a selectable first number is encoded as one subword. Each character of rank between the first and a second number is encoded as two subwords. Each character of rank higher than the second number is encoded three subwords. The second number is fixed by the first number. A two-subword recoder divides by 16 any codeword having two subwords and whose last subword is zero and adds the result to 15 plus the product of 15 times the first number, thereby providing a revised codeword. A three-subword recorder divides by 16 any codeword having three subwords and whose last subword is zero and adds the result to 3573 plus the second number. If the resulting codeword is smaller than 3856 it subtracts 16 from the resulting codeword to provide a revised codeword. <IMAGE>
