Abstract

Se describen diferentes conceptos para mejorar la eficiencia de codificación de video, muchos de ellos permiten codificación de video de una manera que se realiza codificación independiente de mosaicos con reducción, sin embargo, de las pérdidas de eficiencia de codificación asociadas de otro modo con las interrupciones de dependencia de mosaicos, modificando sin embargo simplemente de forma marginal, como mucho, el comportamiento de códec junto a los límites de mosaico.
