Abstract

Un sistema puede identificar un área de imagen rectangular definida y renderizar video correspondiente al área de imagen rectangular definida. El sistema puede recibir una secuencia de bits de video que comprende una imagen que tiene un encabezado y puede recibir datos que especifican una estructura de la imagen. El sistema puede analizar los datos que especifican la estructura de la imagen para un identificador correspondiente a un área rectangular definida en la primera imagen y para un índice de mosaico de un mosaico superior izquierdo en el área rectangular definida. El sistema puede determinar uno o más mosaicos comprendidos en el área rectangular definida basado en el identificador correspondiente al área rectangular definida y el índice de mosaico del mosaico superior izquierdo. El sistema puede reconstruir la imagen que incluye una subimagen que comprende el área rectangular definida basado en el identificador correspondiente al área rectangular definida. El sistema informático puede renderizar la subimagen en el área rectangular definida.
