Abstract

En general, se describen técnicas para indicar una reutilización de parámetros de trama para decodificar vectores. Un dispositivo que comprende un procesador y una memoria puede llevar a cabo dichas técnicas. El procesador puede estar configurado para obtener un flujo de bits que comprende un vector representativo de un eje espacial ortogonal en un dominio de armónicos esféricos. El flujo de bits puede además comprender un indicador de la posibilidad de reutilizar, a partir de una trama anterior, al menos un elemento de sintaxis indicativo de información utilizada cuando se comprime el vector. La memoria puede estar configurada para almacenar el flujo de bits.
