Abstract
Se proporciona un método para señalizar estructuras de subimagen para video codificado. Un decodificador de video recibe datos de un flujo de bits para ser decodificados como una secuencia de imágenes de video. El decodificador de video recibe de la especificación de subimagen de flujo de bits para una o más subimágenes en la secuencia de imágenes de video. La especificación de subimagen identifica una posición y un tamaño para cada subimagen proporcionando un índice que identifica una unidad de árbol de codificación (CTU) para la subimagen. El decodificador de video reconstruye cada subimagen para la secuencia de imágenes de video de acuerdo con la especificación de la subimagen.
