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.

A relay device operable to relay emergency information to a plurality of mobile terminals. The device includes: a receiver configured in use to receive a broadcast signal, the broadcast signal being in a first format and containing the emergency information; a transmitter configured in use to connect to the plurality of mobile terminals using a communication channel; and a processor configured in use to provide the emergency information received in the broadcast signal to the plurality of mobile terminals in a second format using the transmitter, wherein the second format is different to the first format.

The present technology relates to a receiving device, a transmitting device, and a data processing method which are capable of providing a broadcast service using a wide bandwidth more flexibly. A receiving device processes a stream in which delivery configuration information indicating that the stream of the broadcast service is delivered across a predetermined frequency band is included in transmission information which is transmitted through an upper layer higher than a physical layer, the stream having a delivery configuration corresponding to the delivery configuration information, so that a broadcast service using a wider bandwidth can be provided. The present technology can be applied to a FW proxy device connected to a network such as, a home LAN, a head end of a cable operator, a base station of a mobile network, or the like.

A semiconductor device system comprising a central controller and a plurality of hardware nodes. The hardware nodes are interconnected with each other through hard-wired connections which support the transmissions of globally asynchronous continuous-time binary value, CTBV, signals. There is defined a point-to-point(s) communication path between two hardware nodes which are processing nodes, along a sequence of hard-wired connections connected to each other through a switching circuitry. The switching circuitry is controlled by at least one hardware node which are communication node. The switching circuitry selectably connects, based on configuration data, two hard-wired connections in the sequence of hard-wired connections, to permit the transmission of each CTBV signal along the sequence of hard-wired connections. The at least one switching circuitry is latency-deterministic.
