Abstract

Se describen métodos, aparatos, sistemas para el procesamiento de video, que incluyen la codificación de video o la decodificación de video. Un método ejemplar incluye realizar una conversión entre un video que comprende una imagen de video que incluye una o más subimágenes y un flujo de bits del video. El flujo de bits se ajusta a una regla de formato que especifica que un primer elemento de sintaxis que indica si se realiza una operación a través de un límite de una subimagen en la secuencia de video de capa codificada se incluye selectivamente con capacidad de respuesta a un número de subimágenes de la imagen de video.
