Abstract

Un dispositivo de codificación que comprende: un circuito de cuantificación que genera un parámetro de cuantificación que incluye información sobre un libro de códigos de cuantificación vectorial; y un circuito de control que establece el número de bits disponibles de acuerdo con las condiciones para la codificación con base en la diferencia entre el número de bits disponibles para la codificación del subvector objetivo y el número de bits para el parámetro de cuantificación del subvector objetivo.
