Abstract

En varias modalidades, una aplicación de codificación basada en interpolación codifica una primera subsecuencia incluida en un título de medios en cada punto de codificación incluido en un primer conjunto de puntos de codificación para generar subsecuencias codificadas. Posteriormente, la aplicación de codificación basada en interpolación realiza operaciones de interpolación basadas en las subsecuencias codificadas para estimar un primer valor de métrica de medios asociado con un primer punto de codificación que no está incluido en el primer conjunto de puntos de codificación. La aplicación de codificación basada en interpolación luego genera una receta de codificación con base en las subsecuencias codificadas y el primer valor de métrica de medios. La receta de codificación especifica un punto de codificación diferente para cada subsecuencia incluida en el título de medios. Después de determinar que la receta de codificación especifica el primer punto de codificación para la primera subsecuencia, la aplicación de codificación basada en interpolación codifica la primera subsecuencia en el primer punto de codificación para generar al menos una porción de una versión codificada del título de medios.
