Abstract

Se proporciona un método para señalizar valores de desplazamientos adicionales de QP de crominancia que son específicos para grupos de cuantificación, en donde cada grupo de cuantificación explícitamente especifica su propio conjunto de valores de desplazamientos de QP de crominancia. De manera alternativa, una tabla de posibles conjuntos de valores de desplazamientos de QP de crominancia se especifica en el área de encabezamiento del gráfico, y cada grupo de cuantificación utiliza un índice para seleccionar una entrada de la tabla para determinar su propio conjunto de valores de desplazamientos de QP de crominancia. Posteriormente, los valores de desplazamientos de QP de crominancia específicos de grupo de cuantificación se utilizan para determinar los valores de QP de crominancia para bloques en el grupo de cuantificación además de los valores de desplazamientos de QP de crominancia ya especificados para niveles superiores de la jerarquía de codificación de video.
