Abstract:
Methods and apparatus for ensuring protection of transferred content. In one embodiment, content is transferred while enabling a network operator (e.g., MSO) to control and change rights and restrictions at any time, and irrespective of subsequent transfers. This is accomplished in one implementation by providing a premises device configured to receive content in a first encryption format and encodes using a first codec, with an ability to transcrypt and/or transcode the content into an encryption format and encoding format compatible with a device which requests the content therefrom (e.g., from PowerKey/MPEG-2 content to DRM/MPEG-4 content). The premises device uses the same content key to encrypt the content as is used by the requesting device to decrypt the content.
