Abstract

A method of facilitating transport of partially encrypted video is disclosed. The method re-packetizes or otherwise de-concatenates packets carrying the partially encrypted video into packets where all the video in each packet is either encrypted or unencrypted. The re-packetized video packets may include data that identifies whether the packet is carrying encrypted or unencrypted video.
