Abstract

Patente de Invenção: <B>"GERADOR DE IMAGEM NO GUIA"<D>. Um gerador de imagem no guia (21) possui uma saída adaptada para acionar um monitor de vídeo (62) e uma entrada adaptada para receber um sinal de televisão. O gerador de vídeo (34) alimenta sinais de acionamento para a saída em sincronismo com o monitor de vídeo (62). A informação EPG é extraída do sinal de televisão armazenado na memória (26). O tamanho do pixel do sinal de televisão é reduzido. O sinal de televisão com tamanho de pixel reduzido é armazenado na memória (26). Os dados EPG e o sinal de televisão são recuperados da memória (26) e armazenados no gerador de vídeo (34). Os dados EPG e o sinal de televisão são alimentados a partir do gerador de vídeo (34) para a saída em um fluxo de dados contínuo ordenado para produzir uma exibição de imagem no guia (10) no monitor (62). De preferência, o gerador de imagem no guia (21) é implementado com um único chip de circuito integrado.Invention Patent: <B> "GUIDE IMAGE GENERATOR" <D>. An image generator in the guide (21) has an output adapted to trigger a video monitor (62) and an input adapted to receive a television signal. The video generator (34) feeds drive signals to the output in sync with the video monitor (62). EPG information is extracted from the television signal stored in memory (26). The pixel size of the television signal is reduced. The television signal with reduced pixel size is stored in memory (26). EPG data and the television signal are retrieved from memory (26) and stored in the video generator (34). EPG data and the television signal are fed from the video generator (34) to the output in an ordered continuous data stream to produce an image display in the guide (10) on the monitor (62). Preferably, the image generator in the guide (21) is implemented with a single integrated circuit chip.
