DEVICE AND METHOD FOR DATA MULTIPLEX TRANSMISSION, DEVICE AND METHOD FOR DATA MULTIPLEX RECEPTION, AND SYSTEM FOR DATA MULTIPLEX TRANSMISSION AND RECEPTION

摘要

PROBLEM TO BE SOLVED: To maintain continuous data reception even if the transmission line quality is degraded.;SOLUTION: A device has data division hierarchical constitution parts 107, 108, and 109 which divides inputted data into layers according to the importance, a multiplexing control part 110 which performs control so that the data made hierarchical by the data division hierarchical constitution parts 107, 108, and 109 are different in error durability according to the layers, and multiplexing circuits 117 and 118 which multiplex the data for each layer divided by the parts 107, 108, and 109.;COPYRIGHT: (C)2000,JPO
