A home entertainment network transmits audio/video decrypted from a DVD
over a network to a media receiver using a secure channel. The A/V data
is re-encrypted in a second encryption format amenable to transmission
over the network. The media stream is thereby compliant with copy
protection and digital rights management requirements. The media server
constructs an emulated user interface corresponding to an actual
instantiation of a navigation menu on the media server to solicit user
input at the media receiver. The media server alternatively constructs a
unique identifier of the DVD based upon the file structure on the DVD to
search for menu navigation commands over an external network for
heuristic navigation control.
