Systems and methods for relaying in broadcast single-frequency networks are disclosed herein. A single-frequency network can be formed in part using transmitters that receive data via a cooperative relay channel instead of a station-to-transmitter link. In some embodiments, a second channel may use a portion of its transmission time to relay the information to the single-frequency network transmitter using time-division multiplexing. In other embodiments, a second channel may encode the relayed information on a second layer using layer-division multiplexing.

Systems and methods are provided for broadcasting a signal. A multiplexer combines a first signal from a first signal source and a second signal from a second signal source as a time divisional multiplexed signal and provides a timing signal, distinct from the time division multiplexed signal, that indicates, for a given time, from which of the first and the second signal source a corresponding portion of the time divisional multiplexed signal originated. A signal conditioning component receives each of the time divisional multiplexed signal and the timing signal and alters the time division multiplexed signal in a manner that prepares the signal for broadcast. The signal conditioning component dynamically alters its behavior according to the timing signal. An antenna transmits the time division multiplexed signal.

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.

A method for generating a transport stream intended to be distributed to a plurality of broadcast sites. The method includes: modulating a source signal, delivering a modulated signal; sampling the modulated signal, delivering a stream of complex samples; and framing the stream of complex samples, delivering the transport stream, wherein the framing includes: dividing the stream of complex samples into frames; inserting, in each frame, time information associated with the group of successive complex samples making up the frame for the time synchronization of the broadcasting sites.
