    摘要： A method is disclosed that includes: receiving, via a network digital video recorder, a request to record requested content; receiving, via a network digital video recorder at a first time, the requested content in a first format and the requested content in a second format; storing, via the network digital video recorder, the requested content in the first format; storing, via the network digital video recorder, the requested content in the second format; deleting, from network digital video recorder, the requested content in the second format after a predetermined time period; and transcoding, via an on demand transcoder, the requested content in the first format to the requested content in a third format after the predetermined time period. A method is disclosed, including: receiving request to record content; receiving the requested content in a plurality of versions; storing the requested content; from the plurality of versions, identify mezzanine content having a first format and resolution for retaining in storage; for a remaining plurality of versions: determine at least one criterion; retain one or more versions of the remaining plurality of versions in storage until the at least one criterion is met; receiving a request for playback of the requested content to a subscriber's device; determining whether the request may be fulfilled using any stored versions of the plurality of versions of the requested content; if the version having a format and resolution corresponding to the decoding capabilities of the subscriber's device is not stored, regenerate, from a stored version of the plurality of versions, the format and resolution that corresponds to the decoding capabilities of the subscriber's device.
