Abstract

La reproduccion "trick" y/o edicion (14) es aplicada a un flujo de datos original, por ejemplo un flujo de datos MP3. Un flujo MP3 comprende cabezales y datos de senal intercalados unos con otros. Cada cabezal especifica una distancia a un cabezal subsiguiente, cada cabezal correspondiendo a un marco de datos de senal, el cabezal estando asociado con un indicador que indica un punto de inicio de los datos de senal para aquel marco relativo al cabezal. Antes de aplicar la reproduccion "trick" el flujo de datos original es convertido en un flujo de datos intermedio del mismo tipo que el flujo original. Durante la conversion los puntos de inicio de los marcos son movidos a posiciones predeterminadas relativas a los cabezales asociados y los cabezales son modificados para crear espacio adicional entre los cabezales así los marcos caben entre cabezales.
