Abstract

Una modalidad de la presente invención establece una técnica para adaptar la velocidad de bits de reproducción al ancho de banda disponible en un sistema de suministro de contenidos que comprende un servidor de contenidos y un reproductor de contenidos. Un reproductor de contenidos estima de manera periódica si una velocidad de bits de reproducción dada puede factiblemente suministrar la reproducción completa de un título dado asumiendo un ancho de banda disponible en curso. Si la reproducción se vuelve inviable a una velocidad de bits en curso asumiendo un ancho de banda actual disponible, entonces el reproductor de contenidos adapta la velocidad de bits disminuyéndola hasta que se logre una velocidad de bits viable. Si la reproducción es factible usando una velocidad de bits más alta, entonces el reproductor de contenidos puede adaptar la velocidad de bits hacia arriba.
