Abstract
De conformidad con la descripción del presente documento, la información usada en un modo de codificación de paleta puede ser señalada efectivamente. Por ejemplo, la información que se refiere a disponibilidad de un modo de paletas puede ser señalada, y la información que se refiere a un valor de escape cuantificado puede ser señalada con base en la información que se refiere a la disponibilidad del modo de paletas. Además, como un parámetro de cuantificación para el valor de escape cuantificado, la información del parámetro de cuantificación mínimo que se refiere a un modo de salto de transformación puede ser señalada. Por consiguiente, la información requerida para codificación del modo de paletas puede ser eficientemente señalada, y la eficiencia de codificación de escape en un modo de paleta puede ser mejorada.
