摘要:
A method of segregating a hybrid fiber cable network involves assigning a packet identifier (PID) to each of a plurality of hubs on the hybrid fiber cable network; assigning a distinct decryption method to each of the plurality of hubs, so that each of the plurality of hubs is identifiable by its associated decryption method and PID; generating selectively multiple encrypted content for transmission to the hubs, where content encrypted for use by each hub is identified by the hub's assigned PID; and transmitting the selectively multiple encrypted content over the hybrid fiber cable network to the plurality of hubs. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
