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 trigger from a content distribution stream. The trigger contains data indicating an addressable break. A portion of bandwidth is then allocated to an addressable content stream based on the data of the trigger. 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.

A method for broadcast processing, a non-transitory storage medium and an electronic device are provided. The method includes: acquiring a currently-sending broadcast message in a broadcast queue; determining a type of the broadcast message; and calling an interface configured to send the broadcast message and sending the broadcast message to a corresponding broadcast receiver.

Systems and methods are provided for providing content to a receiver. A first broadcaster is configured to broadcast a first content on a channel over an associated first region of signal coverage. A second broadcaster is configured to broadcast a second content, different from the first content, on the channel over an associated second region of signal coverage that overlaps the first region of signal coverage to form a region of overlap. A gateway device is configured to schedule transmission times for the first and second broadcasters, such that a receiver tuned to the channel receives the first and second content as a time divisional multiplexed signal.

Aspects relate to allocation of reduced transmission power time intervals. Nodes may provide respective coverage areas. The nodes may indicate to each other respective configurations of reduced transmission power time intervals.
