DIGITAL VOICE TRANSMISSION SYSTEM, DIGITAL VOICE STORAGE TYPE TRANSMITTER, DIGITAL VOICE RADIO TRANSMITTER AND DIGITAL VOICE REPRODUCTION RADIO RECEIVER WITH DISPLAY
PROBLEM TO BE SOLVED: To reduce increase in the transmission capacity of a radio path even when long voice data are transmitted by a transmitter by selecting one part of a voice message from the transmitter and transmitting this message while adding a system preserved voice data identification code to it. ;SOLUTION: The digital voice data (L bytes) selected by prescribed operation are divided into voice data units (M bytes) as a unit to perform compression, and the respective divided voice data units are compressed and defined as voice compression data units. Data for transmission are defined as the group of integer multiple (K) of voice compression data units so that the compressed data can be expanded within every divided transmission. In the case, a dividing number (J) is selected so as to satisfy a prescribed expression. Thus, the compressed voice data are divided in the integer multiple length for the unit of compressed voice data and allocated to radio claim.;COPYRIGHT: (C)1998,JPO
