Abstract
Various techniques for a library with a significant number of titles are disclosed. A user may select and order a title whenever desired and play back the title fairly instantly. The library is dynamically updated in accordance with a schedule. According to one aspect of the techniques, whenever an ordered title is played back, a beginning portion of the data pertaining to the title is activated to be played back first. The beginning portion of the data is locally cached while the remaining portion of the data is supplied by other designated devices. To facilitate the management of the remaining portion of data for each of the titles in the library, the titles are partitioned into a number of groups or bands. The amount of the remaining portion of the data to be locally cached for each title is determined by a band the title belongs to. Further, as new titles are added in, the titles in each band are updated by retiring relatively unpopular titles to a lower band.
