Abstract

Datos de control para un conjunto de mosaico de movimiento restringido ("MCTS") indican que procedimientos de predicción inter-imagen dentro de un conjunto especificado de mosaicos son restringidos a hacer referencia solo a regiones dentro del mismo conjunto de mosaico en imágenes previas en orden de descodificación (o codificación). Por ejemplo, un codificador de video codifica múltiples imágenes divididas en mosaicos para producir datos codificados. El codificador da salida a los datos codificados junto con datos de control (por ejemplo, en un mensaje de información de mejoramiento suplementario) que indica que las dependencias de predicción inter-imagen a través de límites de conjunto de mosaicos están restringidos para un conjunto de mosaico dado de uno o más de los mosaicos. Un descodificador de video u otra herramienta recibe los datos codificados y los datos de control MCTS, y procesa los datos codificados. La señalización y el uso de datos de control MCTS pueden facilitar la descodificación y presentación de región de interés, transcodificando para limitar datos codificados a un conjunto seleccionado de mosaicos, solidez perdida, paralelismo para codificar y/o descodificar, y otro procesamiento de video.
