Abstract

Se describe un método de procesamiento de video. El método incluye llevar a cabo una conversión entre un video que comprende una o más imágenes que comprenden una o más subimágenes que comprenden uno o más sectores y una representación de flujo de bits del video de acuerdo con una regla, y en donde la representación de flujo de bits incluye una cantidad de unidades codificadas, en donde la regla especifica que un orden de decodificación de unidades codificadas dentro de una subimagen se encuentra en un orden creciente de valores de índice de sectores de nivel de subimagen de las unidades codificadas.
