Abstract
Abstract A method, apparatus, and storage medium for management at least two audio, video, or data (AVD) streams, wherein each AVD stream may comprise a plurality of stream segments. According to a preferred embodiment, the at least two AVD streams are stored in a file. A stream segment directory (SSD) table is stored, having an SSD entry for each stream segment in the file, wherein the SSD entry corresponding to each corresponding stream segment comprises a plurality of fields for characterizing the corresponding stream segment.
