Abstract

En general, esta descripción describe técnicas para codificar bloques de video mediante un proceso de conversión de espacio de color. Un codificador de video, tal como un codificador de video o un decodificador de video, puede determinar si utilizar la conversión de espacio de color para codificar los datos de video. En respuesta a la determinación para utilizar la conversión de espacio de color, el codificador de video puede cuantificar los datos de un primer componente de color de los datos de video al utilizar una primera compensación de un primer parámetro de cuantificación (QP) y cuantificar los datos de un segundo componente de color de los datos de video al utilizar una segunda compensación de un segundo QP, en donde el segundo componente de color es diferente del primer componente de color, y el segundo QP es diferente del primer QP. El codificador de video puede además cuantificar de forma inversa los datos de cuantificación del primer componente de color al utilizar la primera compensación y cuantificar de forma inversa los datos del segundo componente de color al utilizar la segunda compensación.
