Abstract

"ARRANJO E MéTODO PARA TRATAMENTO DOS SINAIS DE IMAGEM EM TELEVISORES COM ACESSO à INTERNET". A presente invenção refere-se a um arranjo e método para tratamento dos sinais de imagem em televisores com acesso à internet compreendendo um módulo Internet (30) dotado de uma CPU (31) e um módulo televisor (50) dotado de meios de exibição de imagem (54) possuindo o dito módulo televisor entradas comutáveis para sinais convencionais de televisão e para sinais provenientes do dito módulo Internet, compreendendo esta última três vias (44) portadoras dos sinais independentes de luminância Y e crominância Cr e Cb, os ditos sinais tendo largura de banda de pelo menos 12MHz. O referido módulo Internet possui interfaces de comunicação com periféricos compreendendo um destes uma unidade (33) contendo um teclado bem como meios de controle de posição do cursor na tela de vídeo, a referida unidade comunicando-se com a dita CPU mediante um enlace de radiofreq³ência. Os circuitos (51, 53) do módulo televisor (50) que realizam o processamento dos sinais de imagem possuem banda de resposta em freq³ência de pelo menos 12MHz.
