Abstract

La presente divulgación se refiere a un dispositivo y método de procesamiento de información con los que se puede inhibir cualquier aumento en la carga de procesamiento de reproducción. De acuerdo con la presente divulgación: información de identificación de tesela que indica la tesela de una nube de puntos que representa un objeto de forma tridimensional como una colección de puntos, correspondiendo la información de identificación de tesela a una unidad de datos de un flujo de bits de la nube de puntos, se usa para generar información de gestión de tesela, que es información para gestionar una tesela que corresponde a una submuestra compuesta por una o una pluralidad de unidades de datos contiguas de un flujo de bits almacenado como muestra en un archivo; y se genera un archivo en el que se almacenan el flujo de bits y la información de gestión de tesela. La presente divulgación se puede aplicar, por ejemplo, a un dispositivo de procesamiento de información o a un método de procesamiento de información.
