Abstract
A method for distributing content on demand over a cable network in which the subscribers are connected to a Central Unit in a hierarchical order of nodes, each node comprises a plurality of subscribers clusters. A Management System is provided at the Central Unit. Some of the subscribers within each cluster are provided with an STB, and the rest of the subscribers within each cluster are provided with an SSTB. Titles are transmitted from the Central Unit to the SSTBs, and stored within the SSTBs. A viewable list of the titles stored in all the SSTBs that are connected within the cluster of that subscriber is provided to each STB subscriber or SSTB subscriber. Whenever a subscriber selects a title for viewing from the viewable list, the selected title is transmitted to the STB or the SSTB of that subscriber from at least one of the SSTBs within the cluster of that subscriber which contain the title or a portion thereof.
