Combined broadcast and unicast delivery

Described herein are techniques for facilitating combined broadcast and unicast delivery of content. According to various embodiments, a media stream from a content provider may be received at a unicast server and at a broadcast server. The media stream may comprise a plurality of media stream fragments. A relative delay may be introduced into the media stream at the broadcast server such that media stream fragments transmitted from the broadcast server are delayed relative to media stream fragments transmitted from the unicast server. The media stream fragments may be transmitted to a user device. The user device may be operable to switch between receiving the media stream fragments from the unicast server and the broadcast server.
