Abstract:
1. A method of segregating a hybrid fiber cable network, comprising: 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 utilizing multiple encryption methods, where content encrypted for use by each hub is identified by the hub's assigned PID; transmitting the selectively multiple encrypted content over the hybrid fiber cable network to the plurality of hubs; receiving the transmitted selectively multiple encrypted content over the hybrid fiber cable at one of the plurality of hubs; remapping the PIDs of the content so that encrypted content shares a PID with unencrypted content to produce remapped content; and at the one of the plurality of hubs, filtering the selective multiple encrypted content to remove encrypted content with PIDs that are not associated with the one of the plurality of hubs.
