Abstract

"TRANSMISSOR PARA TRANSMITIR UM SINAL DE INFORMAçãO DIGITAL, PORTADOR DE GRAVAçãO, RECEPTOR PARA RECEBER UM SINAL DE TRANSMISSãO, E, MéTODO DE TRANSMISSãO DE UM SINAL DE INFORMAçãO DIGITAL" Um transmissor é descrito para transmitir um sinal de informação digital possuindo amostras PCM de M bits através de um meio de transmissão. O sinal PCM de M bits é dividido (8) em um sinal PCM de P bits, onde P < M e um sinal de diferença. O sinal PCM de P bits é uma representação de menor qualidade do sinal de informação digital PCM de M bits e o sinal de diferença é obtido pela subtração do sinal PCM de P bits do sinal PCM de M bits. O sinal de diferença tem os dados comprimidos (16) de forma a obter um sinal de diferença comprimido por dados. O sinal PCM de P bits e o sinal de diferença comprimido por dados são combinados (24) de forma a obter um sinal de transmissão. O sinal de transmissão é transmitido através do meio de transmissão (TRM)."TRANSMITTER TO TRANSMIT A DIGITAL INFORMATION SIGNAL, RECORDING CARRIER, RECEIVER TO RECEIVE A TRANSMISSION SIGNAL, AND, METHOD OF TRANSMITTING A DIGITAL INFORMATION SIGNAL" A transmitter is described to transmit a digital information signal having PCM samples of M bits through a transmission medium. The M bit PCM signal is divided (8) into a P bit PCM signal, where P <M is a difference signal. The P-bit PCM signal is a lower quality representation of the M-bit PCM digital information signal and the difference signal is obtained by subtracting the P-bit PCM signal from the M-bit PCM signal. The difference signal has the data compressed (16) in order to obtain a difference signal compressed by data. The P-bit PCM signal and the difference signal compressed by data are combined (24) in order to obtain a transmission signal. The transmission signal is transmitted through the transmission medium (TRM).
