Abstract

Un aparato electrónico realiza un método de decodificación de datos de video; el método comprende: recibir, a partir del flujo de bits, datos de video correspondientes a un bloque codificado en modo de salto de transformación; decodificar, a partir de los datos de video, una primera palabra de código, una segunda palabra de código y un primer grupo de palabras de código para un pixel dentro del bloque codificado del modo de salto de transformación; derivar un valor de nivel inicial del primer grupo de palabras de código; convertir la primera palabra de código en un resto del pixel de acuerdo con una relación de mapeo predefinida que se genera usando un parámetro de Rice constante; convertir la segunda palabra de código en un valor de signo del resto; y derivar un residuo cuantificado del pixel a partir del resto, el valor del signo y el valor del nivel inicial.
