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 studio-to-transmitter link. In some embodiments, transmitter may use a portion of its transmission time to relay in-band information to the single-frequency network transmitter using time-division multiplexing.

Broadcast relaying via single-channel transmission

Embodiments include methods and systems for activating display of content items on a mobile device based on event criteria associated with a profile of a user. For example, one embodiment comprises a method of activating reception of multimedia data on a mobile device. The method includes receiving metadata identified with at least a portion of one of plurality of broadcasts, determining, based on the metadata identified with the portion of broadcast content, whether the portion contains event metadata satisfying event criteria associated with a profile of a user, and instructing a receiver of a mobile device of the user to tune to the broadcast for receipt of the portion of the broadcast.

Method and system of activating display of multimedia data on a mobile device

Methods and systems generate a multiplex signal including two or more different sub-multiplexes for transmission via a broadcast network. A first sub-multiplex may include several services for broadcast in multiple locations, while multiple second sub-multiplexes may include services for broadcast within particular locations. A statistical multiplexer generates the first sub-multiplex within a first bandwidth allocation. If the first sub-multiplex services cannot fit within the allocated bandwidth, the bandwidth allocation may be adjusted. The statistical multiplexer may generate a second sub-multiplex within a second bandwidth allocation. If the second sub-multiplex services do not fit within the allocated bandwidth, the bandwidth allocation may be adjusted to increase the bandwidth allocated to the second sub-multiplex and decrease the bandwidth allocated to the first sub-multiplex so that the total bandwidth capacity of a broadcast network is not exceeded. This process may be repeated for each of the second sub multiplexes.
