Abstract

RESUMEN Se proporciona un método de decodificación de datos de video, que incluye recibir un flujo de bits que incluye una secuencia de bits que forma una representación de una imagen codificada de los datos de video, particionar la imagen codificada de los datos de video en una pluralidad de bloques mediante el uso de tres o más estructuras de partición diferentes, y reconstruir la pluralidad de bloques de la imagen codificada de los datos de video. La partición de la imagen codificada de los datos de video puede incluir particionar la imagen codificada de los datos de video en la pluralidad de bloques mediante el uso de las tres o más estructuras de partición diferentes, donde al menos tres de las tres o más estructuras de partición diferentes pueden utilizarse en cada profundidad de una estructura de árbol que representa la forma en que se particiona un bloque particular de la imagen codificada de los datos de video.
