A method of processing an emergency alert in a broadcast receiver includes receiving a broadcast signal including an emergency alert table, the emergency alert table including an emergency alert text related to an emergency alert message, information for identifying a viewing target for the emergency alert message and emergency-related broadcast service information for an emergency-related broadcast service, decoding the emergency alert table, displaying the emergency alert text in the decoded emergency alert table, and displaying an additional content related to the emergency alert message. The broadcast signal further includes wake-up information that includes 2 bits representing at least a first wake-up notification of a first emergency or a second wake-up notification of a second emergency different from the first wake-up notification of the first emergency.

To provide a demodulation circuit, a processing circuit, a processing method, and a processing device that are capable of implementing more prompt acquisition of alert information. Provided is a demodulation circuit including a demodulation unit configured to demodulate a broadcast signal received by a reception circuit that receives the broadcast signal, a determination unit configured to determine whether or not acquisition of alert information included in the demodulated broadcast signal is necessary according to a set operation mode, on the basis of first alert notification information indicating an update state of the alert information included in the demodulated broadcast signal, and an output processing unit configured to output second alert notification information corresponding to the operation mode from a predetermined terminal to which a processing circuit having a function to acquire the alert information is electrically connected, in a case where acquisition of the alert information is determined to be necessary.

A method for managing wireless device communications including establishing active, persistent, and repetitive communications with a wireless device operating in a coverage area of a local wireless network. In an example, the local wireless network is an overlay to a portion of a macro wireless network. The repetitive communications include placing a call to the wireless device, completing a call connection to the wireless device, sending a message to the wireless device, receiving and processing a response to the message from the wireless device, and persistently repeating a call function of the placing a call, completing a connection, sending a response, and receiving and processing the response until a specified termination event. In an example, the termination event is a power off of the wireless device.

An emergency system can access a variety of situational data items, such as video streams, facility information, and present and past incident data. The emergency system identifies data items that may be relevant to a particular incident and provides the relevant data items in one or more user interfaces. For example, the emergency system identifies relevant data items based on the reported location of the incident and the type of incident. As additional incident information is received or entered by telecommunicators, the emergency system can further filter and surface data items likely to be useful in responding to the incident. Certain data items may only be permitted to be viewed by certain types of users, or under certain conditions. The emergency system may ensure that data items are provided to authorized users and in permitted use cases.

A device may be configured to parse a syntax element specifying the number of available languages within a presentation associated with an audio stream. A device may be configured to parse one or more syntax elements identifying each of the available languages and parse an accessibility syntax element for each language within the presentation.
