Abstract

"MéTODO E APARELHO PARA GRAVAR E EXIBIR SIMULTANEAMENTE DOIS PROGRAMAS DE VìDEO DIFERENTES". São descritos um método e aparelho para gravar e exibir simultaneamente sinais de vídeo de duas fontes de vídeo diferentes. O aparelho compreende um circuito/lógica de processamento do canal principal (148), um circuito/lógica de processamento do segundo canal (150) e um conjunto de circuitos/lógica comum (152). O conjunto de circuitos comum compreende um canal de codificação de vídeo digital (112) que decodifica tanto um primeiro como um segundo sinal de vídeo codificado. O circuito de processamento do canal principal processa um primeiro sinal de vídeo decodificado com utilização do primeiro pulso de sincronismo para formar uma figura principal para exibição. O circuito de processamento do segundo canal processa um segundo sinal de vídeo decodificado para formar uma figura PIP para combinar com a figura principal para exibição. A figura PIP é produzida utilizando-se um segundo sinal de pulso de sincronismo que é independente do primeiro sinal de pulso de sincronismo. Num modo de gravação, o segundo pulso de sincronismo do canal é acoplado ao circuito de processamento do segundo canal para produzir um sinal de gravação por meio de um codificador digital. O sinal de gravação também forma a figura PIP que está acoplada ao circuito de processamento do canal principal para produzir uma figura PIP que é usada para monitorar o processo de gravação.
