Abstract
A method and system for communicating a conditional access signal through a network includes a source segment generating a first conditional access packet signal comprising a first header having a first destination identifier with a first format. The system also includes a first routing server associated with the source segment generating a second header with a second destination identifier having a second format different than the first format and replacing the first header with the second header. The system also includes a second routing server in communication with the first routing server through the network. The second routing server replaces the second header with a third header having a third destination identifier having the first format to form a third conditional access packet signal. A plurality of receiving devices receive the third conditional access packet signal.
