Abstract: Systems which allow for the insertion of targeted advertisements or other messages into programming content, e.g., using Digital Video Recording (DVR) technology are disclosed. Systems use storage to pre-load advertisements, record content with commercials breaks, and merge the advertisements into the recorded content in the background, so that they are available when the content is viewed in time-shifted mode.

Abstract: Systems and methods for push-based dynamic bandwidth allocation deliver addressable, advertising content in a digital network. Bandwidth is allocated on a push basis in response to receiving a cue tone from a broadcast stream. The cue tone contains data indicating an addressable break. A portion of bandwidth is then allocated to an addressable content stream based on the data of the cue tone. The addressable content stream is then streamed to a receiver during the addressable break and the receiver is tuned from the broadcast stream to the addressable content stream for the duration of the addressable break. The additional bandwidth is de-allocated at the end of the addressable break.
