DIGITAL SIGNAL RECEIVING AND SUPPLYING SYSTEM AND DIGITAL VOICE SIGNAL PROCESSING CIRCUIT AND SIGNAL CONVERSION CIRCUIT

摘要

PURPOSE: To sell information having a commercial value while not converting a digital signal by connecting a player to a signal supply source in one to one correspondence, storing the prescribed digital signal and allowing the player itself to reproduce the signal. ;CONSTITUTION: A player being a terminal equipment is connected electrically to a digital signal supply source in one to one correspondence in the transmission and reception of a digital signal. In this case, The player consists of a large scale integrated circuit LSI comprising a storage circuit RAM storing the digital signal and a gate array or the like, and of a reproduction circuit. A controller CTL of the large scale integrated circuit LSI generates various control signals used for reading and reproducing the digital signal stored in the storage circuit RAM and a control signal used for data input to the storage circuit RAM and then receives a prescribed digital signal in an electric signal, stores it to the storage circuit RAM and uses the player itself to reproduce the stored digital signal.;COPYRIGHT: (C)1993,JPO&Japio
