Abstract

SINAL DE TELEVISãO, PORTADOR DE DADOS, UNIDADE DE PROCESSAMENTO DE SINAL, APARELHO LEITOR DE DISCO, SISTEMA DE RECEPçãO DE SINAL DE TELEVISãO, MéTODO PARA SUPRIR UM SINAL DE IMAGEM DE SAìDA, PRODUTO DE PROGRAMA DE COMPUTADOR, E, MéTODO PARA INCORPORAR UM GERME EM UM SINAL DE TELEVISãO O sinal de televisão (TS) compreendendo dados de imagem (Pi) em cujo sinal de televisão adicionalmente é incluído um germe (S1) utilizável para iniciar um gerador pseudo-randómico, produzindo uma seqüência determinística de valores randómicos a serem usados para adicionar ruídos aos dados de imagem, resolve o problema de visual arbitrário para diferentes aparelhos receptores, cada um com seu próprio ruído pseudo- randómico gerado.
