Abstract

Un método de decodificación de vídeo comprende recibir un flujo de bits que incluye un conjunto de parámetros de imagen (PPS) que contiene un segmento único por bandera de subimagen; determinar si la bandera de segmento único por subimagen tiene un primer valor o un segundo valor, donde el primer valor especifica que cada subimagen que se refiere al PPS incluye un y solo un segmento rectangular, y donde el segundo valor especifica que cada subimagen que se refiere al PPS puede incluir uno o más segmentos rectangulares; decodificar el un, y solo un, segmento rectangular cuando la bandera de segmento único por subimagen tiene el primer valor y los uno o más segmentos rectangulares cuando la bandera de segmento único por subimagen tiene el segundo valor.
