Systems and processes are provided for receiving a request for an audio video program from a display device, transmitting the request for the audio video program via a bidirectional network, receiving the audio video program via the bidirectional network wherein the audio video program is received at a first data rate, transmitting an alternate request for the audio video program via the bidirectional network wherein the alternate request for the audio video program includes are request for the audio video program to be transmitted via a unidirectional wireless transmission, receiving the audio video program via the unidirectional wireless transmission, and transmitting the audio video program to the display device.

The present technique relates to a data processing apparatus and a data processing method each of which enables a burden imposed on processing on a reception side to be reduced. A data processing apparatus produces signaling containing a Null cell number exhibiting the number of Null cells of cells of a sub-frame included in a physical layer frame, and processes the signaling so as for the signaling to be contained in a preamble of the physical layer frame, thereby enabling a burden imposed on processing on a reception side to be reduced. The present technique, for example, can be applied to data transmission complying with the broadcasting standards such as ATSC3.0.

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.

Disclosed herein is a media processing device including a receiver configured to receive a service and receive a service list for the service from a service list server, a processor configured to perform service discovery for the service based on the service list, and a displayer configured to display the service based on the service discovery. Disclosed herein is a media processing device including a memory and a processor connected to the memory, wherein the processor may be configured to transmit a service, and transmit a service list for the service from a service list server, wherein the service list may be used to perform service discovery for the service.

An electronic device may include an interface unit, and a processor for storing information related to a plurality of broadcast channels that can be received through the interface unit, receiving a user input for selecting a channel number, identifying, on the basis of the stored information related to the plurality of broadcast channels, a broadcast standard corresponding to the selected channel number if a broadcast signal of a channel corresponding to the channel number selected according to the user input is not received, processing the frequency band of the broadcast signal corresponding to the selected channel number according to the identified broadcast standard, and controlling so that the stored information related to the plurality of broadcast channels is updated according to a processing result.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. When automatically switching from presenting a service on a first frequency to a second frequency such as when a mobile receiver is moving through a boundary region between two broadcasters, the current broadcaster application is notified and depending on the context, may continue executing or send data to the new broadcaster application.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a lower level signaling PLP is used to identify a channel quality metric for identifying the best frequency to receive a broadcast service on which is sent from both stations.

[Problem] To provide: a decoding device that decodes and replays, in a suitable order, sequentially transmitted information; a reception device; a transmission/reception system; a decoding method; and a storage medium having the decoding program stored therein. [Solution] A decoding unit 21 that decodes packets sent from a transmission device 10. A decoding order determination unit 22 determines the order of packets to be decoded by the decoding unit 21, on the basis of adjustment information that is included in the packet and corresponds to a time adjustment for making Coordinated Universal Time approach Universal Time. The packets include order information indicating the order in the same IP data flow. The decoding order determination unit 22 determines, on the basis of the order information, the order of packets to be decoded by the decoding unit 21, if the adjustment information indicates that a time adjustment will occur.

A method and device for transmitting or receiving a broadcast signal are discussed. The method for transmitting the broadcast signal can include processing one or more Internet Protocol (IP) packets into link layer packets, processing the link layer packets to output the broadcast signal, and transmitting the broadcast signal. The one or more IP packets can carry components of a service and service signaling information for signaling the components of the service. The broadcast signal can further include a service list table. The service list table can include one or more of service identification information for identifying the service, capabilities information related to the service, channel number information of the service, category information for indicating a type of the service, protocol information for representing a type of a protocol used to deliver the service signaling information.

To secure easiness of component selection at a reception side. A transmission stream is generated in which a first transmission packet including a predetermined component and a second transmission packet including signaling information related to the predetermined component are multiplexed in a time division manner.
