Abstract

Cuando un cuadro inmediatamente precedente a un cuadro objetivo para codificación a codificar por una primera unidad para codificación opera bajo un esquema para codificación predictiva lineal se codifica por una segunda unidad para codificación que opera bajo un esquema para codificación diferente del esquema para codificación predictiva lineal, el cuadro objetivo para codificación puede ser codificado bajo el esquema para codificación predictiva lineal al inicializar el estado interno de la primera unidad para codificación. Por lo tanto puede lograrse codificar el procesamiento realizado bajo una pluralidad de esquemas para codificación incluyendo el esquema para codificación predictiva lineal y un esquema para codificación diferente del esquema para codificación predictiva lineal.
