Abstract

"PROCESSO E SISTEMA PARA EMBUTIR DADOSSUPLEMENTARES EM UM SINAL CODIFICADO E GRAVARDITO SINAL CODIFICADO EM UM PORTADOR DE GRAVAçãO,PORTADOR DE GRAVAçãO E SISTEMA PARA REPRODUZIRDADOS GRAVADOS EM UM PORTADOR DE GRAVAçãO". Umprocesso para embutir dados suplementares em um sinal codificadoque é diferente do formato usado para codificar dados do sinalcodificado e gravar dito sinal em um portador de gravação emforma de disco aplicando marcas de um primeiro tipo físico. Osdados suplementares são codificados conforme um segundoformato que é diferente do formato usado para codificar dados dosinal codificado. Informação de descrição de formato relacionadaao segundo formato é gravada no portador de gravação tanto commarcas do mesmo tipo físico mas moduladas de acordo com umasegunda modulação diferente ou com marcas de um segundo tipoque têm características físicas diferentes com respeito ao primeirotipo."PROCESS AND SYSTEM FOR BUILDING SUPPLEMENTARY DATA IN A CODED AND GRAVARDITE SIGN CODED SIGN IN A RECORDING CARRIER, RECORDING CARRIER AND SYSTEM FOR PLAYING RECORDED IN A RECORDING CARRIER". A process for embedding supplementary data in an encoded signal that is different from the format used to encode data from the encoded signal and record that signal on a disk-shaped recording carrier by applying marks of a first physical type. Supplementary data is encoded according to a second format that is different from the format used to encode encoded data. Format description information related to the second format is recorded on the recording carrier either with brands of the same physical type but modulated according to a different second modulation or with marks of a second type that have different physical characteristics with respect to the first type.
