Provided are improved systems, methods, and devices for downloading content using a second transport protocol within a generic content download protocol, such as using a FLUTE session to download content within a DLOTA session. The DLOTA download descriptor file can point to a media object which is a FLUTE session descriptor file. The DLOTA session permits the FLUTE session to occur before sending an install notification, or content download notification. This type of binding permits users to receive multicast and broadcast unidirectional content delivery masked by a generic content download protocol. Accordingly, the generic content delivery architecture can provide additional functionality to the underlying transfer protocol, such as dynamic capability check, user confirmation, and content download notification.
