The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method which can use binary format signaling data and text format signaling data in combination. There is provided a reception apparatus including a first acquisition unit which acquires, preceding text format second signaling data to be transmitted in a lower-level layer than an IP layer in a hierarchy of a protocol of an IP transmission system and containing control information independent of a service identified by an IP address, binary format first signaling data containing a flag indicating whether the second signaling data exists in digital broadcast using the IP transmission system, a second acquisition unit which acquires the second signaling data on the basis of the first signaling data, and a control unit which controls operation of the units which perform various types of processing on the basis of the second signaling data. The present technology can be applied to, for example, a television receiver.

The present invention proposes a method for providing a broadcast service. The method for providing a broadcast service in a broadcast signal transmitter according to the present invention may comprise the steps of: encoding media data to a media stream; creating signaling information for signaling the media stream; multiplexing the encoded media stream and the signaling information; and transmitting a broadcast signal comprising the multiplexed media stream and the signaling information.

Systems and methods are disclosed for broadcasting and receiving a terrestrial broadcast signal containing emergency alert information in machine-readable format. The method includes the steps of scanning a Transport Stream associated with the terrestrial broadcast signal. The Transport Stream contains one or more Transport Stream packets and a plurality of tables, which are parsed to identify a channel having a type specified as containing emergency alert information. An MPEG-2 program having said emergency alert information may then be acquired for delivery through a terrestrial broadcast receiver.

A method and apparatus for providing an ETWS message to a wireless transmit receive unit (WTRU). The WTRU is configured to receive a paging message indicating a change in system information, wherein in response to the paging message to receive a system information block (SIB) 1 to determine a schedule for reception of earthquake and tsunami warning system (ETWS) information in system information blocks (SIBs). The WTRU is further configured to receive the SIBs with the ETWS information and to separately receive segments of an ETWS message and to combine the segments to reproduce the ETWS message.

Remote actuation of machines or machine systems is realized by a system for coupling a radiobeacon to a smart device and in turn to a broader network. The smart device is configured as a proximity-actuated “community nodal device” by an application that operates as part of the system. The community nodal device is given instructions to function as a “soft switch”: to automatically “upswitch”, amplify, and broadcast low energy, local area radiobeacon “messages” to a cloud-based server, where the message is interpreted according to rules or policies established by an operator, and a command is transmitted for execution to a remote device. Conventional smart devices generally discard data not addressed to the owner of the smart device. Instead of discarding third party messages, the system preempts their handling, and using a soft switch formed from background resources, anonymously, without access to the message by a user interface of the proxy device, and without waiting for a network query from the host, engineers an “upswitched transmission” of radiobeacon-generated data to a cloud host. Advantageously, confidential sharing of ad hoc community resources results in a negligible load on background resources of the community nodal device. Messages may include a sensor data payload. Bit overloading enables a sensor data payload to be compressed into a few hundred bytes or less.

A multimedia playing system for automatically notifying abnormal situations has a TV dongle and a network security camera connected to the TV dongle through network. The TV dongle has an email processing server module. The network security camera has an email transmitting module. When the network security camera detects an abnormal situation, an event message is transmitted to the email processing server module. The email processing server module accordingly generates a command. According to the command, the TV dongle transmits a control signal to control a digital TV to immediately display the abnormal situation. Therefore, the multimedia playing system automatically informs a user of the occurrence of the normal situation.

Systems for aiding emergency responders are described. An exemplary system may include a primary device and a secondary device. The primary device may be configured to provide audio communication between the primary device and one or more of the plurality of secondary devices along a wireless communication path. The primary device may be configured to compress audio communication for transmission over a low bitrate band. The plurality of secondary devices may be configured as a network where each of the devices is configured to communicate with at least two other secondary devices. The secondary devices may also be configured to receive audio communication from the primary device and automatically transmit the received audio communication to one or more other of the secondary devices.
