Abstract
A method consistent with certain implementations involves receiving a stream of legacy encrypted main content that contains selectively DRM encrypted duplicate content; decrypting the legacy encrypted stream of content; eliminating the duplicate content that is not DRM encrypted; generating a selectively DRM encrypted stream of content; and providing the selectively DRM stream of content as an output signal for consumption by a device residing on a home entertainment network. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
