METHOD AND APPARATUS FOR EDITING DATA STREAMS |
摘要 |
MP3 decoders decode MP3 data streams that comprise headers and signal data interspersed with each other, each header specifying a distance to a subsequent header, each header corresponding to a frame of signal data, the header being associated with a pointer that points to a starting point of the signal data for that frame relative to the header. An editing system cuts tracks from existing data streams. During editing, a user signals a header corresponding to the start of the desired track. The track is from the data stream, including a part of the data stream pointed at by the header and preceding the specified header. A new MP3 compatible data stream is written to a medium. The new data stream contains said header as first valid header and said part of the data stream preceding the header. |
