Abstract
Methods and apparatus for expanding the storage capacity of one or more DVRs in a household by attaching them to a shared network storage device are described. Recorded content is encrypted in at least some embodiments on a per customer basis rather than on a per DVR basis allowing content to be moved between devices at a customer premise and played back by any of the devices at the customer premise where the content was recorded. Network congestion delays are avoided by allowing a user to specify when content is to be locally available at a DVR and moving the content prior to the specified time, if necessary, to the local storage device in the DVR. DVRs can access, decrypt and display content stored on the network storage device that was recorded by another DVR in the same household.
