Abstract

Se proporciona un método para transmitir contenido multimedia que proporciona un tamaño de fragmentos significativamente reducido. El método incluye recibir una o más transmisiones de transporte adaptativas en un búfer de memoria en un transmisor HTTP de una unidad de preparación multimedia. Las transmisiones de transporte recibidas incluyen una pluralidad de segmentos conmutables que comprende cada uno o más fragmentos de entrega, los segmentos conmutables se marcan con los puntos limitantes de segmento y los fragmentos de entrega se marcan con los puntos limitantes de fragmento. Uno o más de los fragmentos de entrega después se transmiten de un segmento conmutable solicitado a un dispositivo de cliente solicitante hasta que se alcance un punto limitante de segmento de terminación, en donde cada fragmento de entrega es independientemente decodificable, y un dispositivo de cliente puede comenzar a decodificar y a presentar los fragmentos de entrega recibidos aun cuando el transmisor HTTP todavía no ha recibido completamente el segmento conmutable solicitado completo de la unidad de preparación multimedia.
