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."ARRANGEMENT AND METHOD FOR TREATMENT OF IMAGE SIGNS IN TV WITH INTERNET ACCESS". The present invention relates to an arrangement and method for processing image signals in Internet access televisions comprising an Internet module (30) having a CPU (31) and a television module (50) having video display means. (54) said television module having switchable inputs for conventional television signals and for signals from said Internet module, the latter comprising three channels (44) carrying the independent luminance Y and chrominance Cr and Cb signals, said signals having bandwidth of at least 12MHz. Said Internet module has communication interfaces with peripherals, one of which comprises a unit (33) containing a keyboard as well as means of controlling the position of the cursor on the video screen, said unit communicating with said CPU by means of a radio frequency link. . The circuitry (51, 53) of the television module (50) which performs image signal processing has a frequency response band of at least 12MHz.
