Abstract

Se proporciona un codificador de video (101) de acuerdo con las modalidades. El codificador de video (101) está configurado para codificar una pluralidad de imágenes de un video generando una señal de video codificado, en donde cada una de la pluralidad de imágenes comprende datos de imagen originales. El codificador de video (101) comprende un codificador de datos (110) configurado para generar la señal de video codificado que comprende datos de imagen codificados, en donde el codificador de video está configurado para codificar la pluralidad de imágenes del video en los datos de imagen codificados. Por otra parte, el codificador de video (101) comprende una interfaz de salida (120) configurada para dar salida a los datos de imagen codificados de cada una de la pluralidad de imágenes. Además, se proporcionan decodificadores de video, sistemas, métodos para codificar y decodificar, programas de computadora y señales de video codificado de acuerdo con las modalidades.
