<p>A method of pre-caching data using thread lists, and a multimedia or video editing system using such a pre-caching method, are disclosed. A list of data which will be required by a host application is passed to a data storage device such as a hard disk drive (120), CD ROM drive or other data storage device, which locates the data and stores it in its own storage device buffer (124). The thread list may include a video thread and an audio thread, as well as a data access parameter reflecting host data application requirements. The data access parameter may include at least one of data priorization, cache management, error processing including a resend capability, and data supply rate. The thread list may also include data specifying percentages of the drive buffer (124) to be reserved for read ahead data and data which has been previously provided to the host computer (100).</p> |
