ABSTRACT:
Trick play and/or editing is applied to an original data stream, for example an MP3 data stream which includes headers and signal data interspersed with each other. Each header specifies a distance to a subsequent header, each header corresponding to a frame of signal data, the header being associated with a pointer that points a starting point of the signal data for that frame relative to the header. Before applying trick play, the original data stream is converted into an intermediate data stream of the same type as the original stream. During conversion, the starting points of the frames are moved to predetermined positions relative the associate headers and the headers are modified to create additional space between the headers so that the frames fit between headers.
