<p>A system for transporting content to subscriber premises (Fig. 1) includes a centralized content repository (22), a subscriber unit, and a network connecting the subscriber unit and repository (30). The content can be video, images, or other files and the network can include a digital subscriber line link. The repository stores higher quality parts (24) of the content files corresponding to the higher quality parts in the repository. The lower quality parts ca be downloaded to the subscriber unit during off-peak hours. During operation, a subscriber (28) selects a locally stored file. In response to the selection, the repository downloads at least one of the higher quality parts corresponding to the selected file to be combined with one of the lower quality parts stored by the subscriber unit for real-time presentation of the content.</p> |
