Abstract

Un sistema de procesamiento de señales de video digitales recibe paquetes codificados de datos que representan informacion de imagen de video en forma comprimida. Un descodificador de video (1509) y una memoria de acceso aleatorio de video asociada (1513) se usan para descodificar y descomprimir los paquetes de video para formar grupos de palabras digitales representativos de la imagen de video. Los grupos de imágenes de video se organizan en un formato de componentes comprimidos (por ejemplo , Y, U, V en la proporcion 4:2:2) en relacion con el formato de compresion de imágenes de video en donde los pares de componentes de color relacionado (U, V) corresponden a más de un pixel. El descodificador de video (1509) también incluye una unidad de despliegue en pantalla (OSD) (1509-9) que convierte un mapa de bits de gráficos almacenado en una seccion (1513-3) de la memoria de acceso directo (1513) de video en grupos de palabras digitales representativas de la imagen gráfica. Los grupos de imágenes gráficas se organizan en un formato de componentes no comprimidos (Y, U, V en la proporcion 4:4:4). Los componentes de color relacionado (U, V), de los grupos de imágenes gráficas no comprimidas, se suprimen mediante un convertidor, para formar nuevos grupos de imágenes gráficas que tienen el mismo formato que los grupos de imágenes de video, los cuales se pueden multiplexar fácilmente con los grupos de imágenes de video, para insertar una imagen gráfica dentro de una imagen de video.
