Abstract

Se proporciona un método de codificación implementado por un dispositivo de decodificación. El método incluye analizar un flujo de bits para obtener una bandera de un encabezado de imagen del flujo de bits, en donde la bandera indica si una imagen actual es una imagen I cuando la bandera indica que la imagen actual es una imagen, un elemento de sintaxis diseñado para la interpredicción se infiere a un valor por defecto; o cuando la bandera indica que la imagen actual es una imagen P o B, obteniendo un elemento de sintaxis diseñado para la interpredicción del encabezado de la imagen.
