Abstract

El problema de la tecnología convencional era codificar repetidamente la misma información utilizando muchos bits de codificación de información de descripción de memoria intermedia respecto a imágenes de referencia para ser utilizados en codificación predictiva de video. Un dispositivo de codificación predictiva de vídeo incluye: medios de alimentación para implementar alimentación de imágenes que constituyen una secuencia de vídeo; medios de codificación que realizan codificación predictiva de una imagen de destino utilizando, como imágenes de referencia, imágenes que se han codificado y después reconstruido en el pasado, para generar datos de imagen comprimidos; medios de reconstrucción para descifrar los datos de imagen comprimida para reconstruir una imagen reproducida; medios de almacenamiento de imagen para almacenar la imagen reproducida como una imagen de referencia para la codificación de una imagen posterior; y medios de gestión de memoria intermedia para controlar los medios de almacenamiento de imagen, en donde los medios de gestión de memoria intermedia controlan los medios de almacenamiento de imagen, (antes de codificación predictiva de la imagen de destino), sobre la base de información de descripción de memoria intermedia BD[k] relacionada a imágenes de referencia que se utilizan en la codificación predictiva de la imagen de destino, codifica la información de descripción de memoria intermedia BD[k] con referencia a información de descripción de memoria intermedia BD[m] para una imagen diferente de la imagen de destino y agrega sus datos codificados a los datos de imagen comprimida.
