Abstract

PURPOSE:To realize high-efficiency transmission with an economical constitution, by inserting information, which indicates whether the data length is a fixed length or not, and information, which indicates the data length or the dummy data length only for the data length of a fixed length or less. CONSTITUTION:Transmission data is segmented by every prescribed length and is divided into data P1-Pn of one-packet share. Prescribed-length data P1-Pn-1 are provided with flag Q, which indicates whether data is a prescribed length or not, following to the synchronizing flag F, address information A, packet control information, and other information; and if data is a prescribed length, flag Q is set to ''1'', and data is inserted after the flag, and check bit CRC is added, and synchronizing flag F is added at last. Meanwhile, if data is shorter than the prescribed length like data Pn, flag Q is set to ''0'', and information N indicating the length of data is inserted after flag Q, and dummy data D is inserted after data Pn, thus constituting a fixed-length packet.
