Abstract
In certain embodiments, a selective encryption encoder has a packet identifier that identifies packets of a specified packet type. The specified packet type includes packets carrying data representing a video slice wherein the video slice contains a larger amount of data than a threshold amount of data. A packet duplicator duplicates the identified packets to produce first and second sets of the identified packets. Packets are sent and received to and from a primary encryption encoder to encrypt the first set of identified packets under a first encryption method. A secondary encrypter encrypts the second set of identified packets under a second encryption method. This abstract should not be considered limiting since embodiments consistent with the present invention may involve more, different or fewer elements.
