Abstract

Se presentan sistemas y métodos para la transición gradual eficiente (u otros múltiples procesamientos de clip) de los flujos comprimidos de información de dominio en un dispositivo de usuario o cliente, tales como un teléfono, tableta, computadora o reproductor MP3, o cualquier dispositivo de consumo con reproducción de audio. Los sistemas de implementación de ejemplo podrían proporcionar la transición gradual entre los flujos de información AAC/Mejorado AAC Plus (EAACPlus) o entre los flujos de información MP3 o incluso entre los flujos de información de los formatos no acoplados (por ejemplo, AAC con MP3 o MP3 con AAC). Además, estos sistemas son distinguidos por el hecho que la transición gradual es directamente aplicada a los flujos comprimidos de bits, de modo que una única operación de decodificación podría ser realizada sobre el flujo resultante de bits. Además, utilizando los métodos descritos, también puede ser ventajosamente implementada una transición gradual similar en el dominio comprimido entre los flujos de información que utilizan otros formatos de compresión, tales como por ejemplo, MP2, AC-3, PAC, etc. De esta manera, en las modalidades de ejemplo de la presente invención, es decodificado un conjunto de cuadros de cada flujo de entrada asociado con el intervalo de tiempo en esta transición gradual, y es combinado y nuevamente codificado con una transición gradual u otro efecto ahora en el flujo comprimido de bits. Una vez enviado a través del decodificador de dispositivo de cliente, el usuario escucha el efecto de transición. Los únicos datos de entrada que son decodificados y procesados son los asociados con la porción de cada flujo utilizado en la transición gradual, la mezcla u otro intersticial, y de esta manera, la gran mayoría de los flujos de entrada se dejan comprimir.
