TRANSMISSION-RECEPTION SYSTEM, TRANSMISSION APPARATUS, RECEPTION APPARATUS AND TRANSMISSION-RECEPTION METHOD

摘要

A TRANSMISSION-RECEPTION SYSTEM IS DISCLOSED WHEREIN DIGITAL DATA WHOSE MISS CONNOT BE ADMITTED CAN TRANSMITTED ON THE REAL TIME BASIS WITH CERTAINTY AND ACCURATELY WITHOUT IMPOSING A HIGH LOAD TO ANY OF ELECTRONIC EQUIPMENTS ON THE TRANSMISSION SIDE AND THE RECEPTION SIDE. DCMT DATA AS ANCILLARY DATA WHOSE MISS CANNOT BE ADMITTED ARE SUPPLIED FROM A DVD-AUDIO DECODER (12) OF A DVD (1) PLAYER TO A MICROCOMPUTER OF A DIGITAL &Igr;/F SECTION (13). THE MICROCOMPUTER (133) SUPPLIES THE DMCT DATA TO A TRANSMISSION DATA PACKET TO A TRANSMISSION DATA PACKET COMPOSITE MODULATOR OF A LINK LAYER TRANSMITTER-RECEIVER (322).THE MODULATOR (1311) DIVIDES THE DMCT DATA INTO DATA UNITS OF AN EQUAL DATA LENGTH AND ADDS A LABEL AND A SUBLABEL TO EACH OF THE DATA UNITS TO FORM A TRANSMISSION DATA SET. THE SUBLABEL INDICATES WHETEHER THE CORRESPONDING DATA UNIT IS THE FIRST DATA UNIT OR A SUCCEEDING DATA SET SUCCEEDING TO THE FIRST DATA UNIT. THE TRANSMISSION DATA SETS OF THE DMCT DATA FORMED BY THE MODULATOR (1311) ARE TRANSMITTED.(FIGURE 1)
