Abstract

"PORTADOR DE GRAVAçãO, PROCESSO DE GRAVAR UM SINAL ESTéREO E UM SINAL DE DADOS SOBRE O MESMO, E, APARELHOS GRAVADOR E DE REPRODUçãO" A invenção refere-se a um portador de gravação portando um sinal estéreo e um sinal de dados. O sinal de dados compreende uma primeira parte e uma parte remanescente. Um primeiro canal sobre o portador de gravação compreende um sinal compósito. O sinal compósito é obtido pelo combinar o sinal estéreo e a primeira parte do sinal de dados, de preferência pela utilização de técnicas de dados embutidos. Um segundo canal sobre o portador de gravação compreende a parte remanescente do sinal de dados. A invenção adicionalmente refere-se a um processo, um aparelho para gravar e um aparelho para reprodução para gravar/reproduzir o sinal estéreo e o sinal de dados sobre um portador de gravação.
