Abstract
Un método de procesamiento de video ejemplar incluye realizar una conversión entre una imagen de un video que comprende una o más subimágenes y una representación de flujo de bits del video. La representación de flujo de bits se ajusta a una regla de formato que especifica que la información sobre una subimagen se incluye en la representación de flujo de bits con base en al menos uno de: (1) una o más posiciones de esquina de la subimagen, o (2) una dimensión de la subimagen. La regla de formato especifica además que la información sobre la subimagen está posicionada después de información sobre un bloque de árbol de codificación en la representación de flujo de bits.
