Abstract
Un método de decodificación de una imagen de un flujo de bits de video implementado por un dispositivo de decodificación, el flujo de bits incluye un encabezado de segmento de un segmento actual y datos que representan el segmento actual, el método comprende: obtener un parámetro utilizado para derivar el número de mosaicos en el segmento actual del encabezado del segmento, en caso de que se cumpla una condición, en donde la condición comprende: la dirección del segmento del segmento actual no es la dirección del último mosaico en la imagen dónde se encuentra el segmento actual; reconstruir el segmento actual que utiliza el número de mosaicos en el segmento actual y los datos que representan el segmento actual.
