Abstract

Se describen innovaciones en codificación y descodificación adaptables para unidades de una secuencia de video que pueden mejorar la eficiencia de codificación cuando se cambia entre espacios de color durante la codificación y descodificación. Por ejemplo, algunas de las innovaciones se refieren al ajuste de cuantificación o escalamiento cuando un codificador cambia espacios de color entre unidades dentro de una secuencia de video durante la codificación. Otras innovaciones se refieren al ajuste de cuantificación o escalamiento inverso cuando un descodificador cambia espacios de color entre unidades dentro de una secuencia de video durante la descodificación.
