A method for transmitting a broadcasting signal according to the present invention suggests a system capable of supporting a next generation broadcasting service in an environment which supports a next generation hybrid broadcast using a terrestrial broadcast network and an internet network. Furthermore, in an environment which supports a next generation hybrid broadcast, suggested is an efficient signaling scheme which can embrace both a terrestrial broadcast network and an internet network.

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.

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 distribution system and reception apparatus, and methods thereof, are provided for broadcasting and receiving a plurality of non-backwards-compatible services. The broadcasting method includes receiving, by a first service provider, a plurality of first services, which include a first service from each of the first and second service providers. The first service provider generates a first broadcast multiplex, including the plurality of first services, and broadcasts the first broadcast multiplex on a first broadcast channel allocated to the first service provider. A second service provider receives a plurality of second services, which include a second service from each of the first and second service providers. The second service provider generates a second broadcast multiplex, including the plurality of second services, and broadcasts the second broadcast multiplex on a second broadcast channel allocated to the second service provider.

A transmitting apparatus, a receiving apparatus, and a data processing method that enable efficient transmission of periodically transmitting information. The transmitting apparatus arranges, in a physical layer frame including a preamble and a data portion, periodically transmitting transmission information in an area that is extractable temporally before other information arranged in the data portion, and transmits the physical layer frame as a digital broadcast signal. The apparatuses and method are applicable to, for example, digital broadcasting using an IP transmission method.

A system (1000) is disclosed including a resource allocation optimization (RAO) platform (1002) for optimizing the allocation of resources in network (1004) for delivery of assets to user equipment devices (UEDs) (1012). The RAO platform (1002) determines probabilities that certain asset delivery opportunities (ADOs) will occur within a selected time window and uses these probabilities together with information concerning values of asset delivery to determine an optimal use of asset deliveries. In this regard, the RAO platform (1004) received historical data from repository (1014) that facilitates calculation of probabilities that ADOs will occur. Such information may be compiled based on asset delivery records for similar network environments in the recent past or over time.
