Abstract

Los aparatos y métodos de procesamiento de video para procesar imágenes de video que se refieren a un conjunto de sintaxis de alto nivel incluyen recibir datos de entrada, determinar un primer elemento de sintaxis que indica si se deshabilita o restringe el remuestreo de imagen de referencia, determinar un segundo elemento de sintaxis que indica si se deshabilita o restringe la partición de subimagen, y codificar o decodificar las imágenes de video. El primer y segundo elementos de sintaxis se restringen para deshabilitar o restringir la partición de subimagen cuando se habilita el remuestreo de imagen de referencia o deshabilitar o restringir el remuestreo de imagen de referencia cuando se habilita la partición de subimagen. El primer elemento de sintaxis y el segundo elemento de sintaxis son elementos de sintaxis señalizados en el conjunto de sintaxis de alto nivel.
