摘要：For a network with a distributed hierarchical broadcast architecture, a method for efficiently and reliably distributing data content and remotely managing the storage of content. Both the distribution and the storage management methods are rule-based, utilizing network resources in an efficient manner. Simple and reliable mechanisms are provided for ensuring both data integrity and control over storage utilization. At each stage throughout the network hierarchy, content is distributed to nodes in the subsequent stage based on rules. The rules may be modified at each stage. Only one device in the hierarchy is required to maintain detailed information of the storage characteristics of storage devices and content therein in stages which are subsequent to it in the network. The recipient device owner specifies a set of preferences which may be used for local filtering, or which the owning (or other) entity may use to select data which targets the client's interests. The downloaded data may be presented to the client in the form of an interactive application, video, audio, still image, or other format.
