Title:
DATA DISTRIBUTION SYSTEM
Document Type and Number:
Japanese Patent JP3179347
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To make the memory capacity of a receiving terminal an irreducible minimum and to reduce time for transferring data from a transmitter.
SOLUTION: In this data distributing system, a transmitter 1 is provided with a modulation means which stores data stored in a storage device of a large capacity by dividing into n-pieces (n is an integer not less than 2) and then modulates them to n-number of different carrier waves, and a composing and sending means composing the n-number of modulated carrier waves modulated by this modulation means and sending it to a line 6. The plural receiving terminals 7-1 to 7-m are respectively provided with a selecting means selecting one specific previously set modulated carrier wave from among n-number of modulated carrier wave transmitted through the line 6, and a storing means demodulating the selected modulated wave and temporarily storing demodulated data.
