摘要
A continuous stream of formatted digital data, such as a video segment, audio segment, or information stream, appears to be a fixed length segment under certain circumstances, defining a virtual segment within the continuous stream which moves forward in time in synchrony with the continuous stream. The virtual segment thus defined can be explored in a non-linear fashion at arbitrary playback rates. For instance, concepts such as rewind, pause, frame advance, and fast forward become meaningful even though the continuous stream never ceases.
