摘要： Video On Demand system providing video programs between a program provider and a plurality of clients coupled over a peer to peer network. Transmitting a requested video program from a first client on a first channel. Allocating a second channel for transmitting the video program requested by a second client. The first client forwarding the video program to the second client on the second channel from the beginning of the video program received and stored. Controlling the second client to receive and store the video program sent on the first channel in synchronization with the first client.

摘要： Methods and apparatus for key distribution in a conditional access system, assuming that the set of all user nodes which the system can accommodate is a complete set, and a subset is composed of all user nodes or part of user nodes. One method comprises: decomposing said subset into at least one secondary subset; assigning a different user key to each secondary subset, each said user key being transmitted to all users in a corresponding secondary subset; encrypting an entitlement key by using each said user key so as to generate a cipher text corresponding to each said secondary subset; and combining said cipher text to generate a media key control block and transmitting said media key control block to all users in said subset. Since a classification method of a binary tree and a multiple tree is used, the invention can save a lot of network resources.
