Abstract: Provided is a configuration that permits confirmation of emergency information viewing results on a reception apparatus, an endpoint of emergency information such as TV. A data processing section of a reception apparatus such as TV that receives and outputs emergency information generates an emergency information viewing result report that contains a record of emergency information viewing result information and sends the generated emergency information viewing result report to a management server and so on. The data processing section generates an emergency information viewing result report that contains a record of an identifier of emergency information output by the reception apparatus and emergency information output time information in accordance with a CDM (Consumption Data Message) format. The CDM keeps a record of not only emergency information output time information but also reception apparatus position information, emergency information sender information, and so on.

Abstract: This technology relates to a receiving apparatus, a transmitting apparatus, and a data processing method for displaying emergency information communicated in an emergency at appropriate positions. The receiving apparatus acquires metadata transmitted by a digital broadcast signal, the metadata including first emergency information required to be announced urgently and display position information indicating whether there is second emergency information embedded in uncompressed video data, the display position information further indicating, if the second emergency information is embedded in the uncompressed video data, the display position of the second emergency information on a screen.

Abstract: The present technology relates to a receiving apparatus, a transmitting apparatus, and a data processing method which are capable of providing detailed information of emergency information that is to be announced in case of emergency. The receiving apparatus receives a digital broadcast signal, and performs a process with respect to an emergency information application for presenting detailed information of emergency information on the basis of control information that is included in the digital broadcast signal and that includes information about the detailed information of the emergency information which needs to be announced urgently. The present technology is applicable to a television receiver, for example.

Abstract: The present technology relates to a receiver apparatus, a transmitter apparatus, and a data processing method that are configured to execute an operation related with viewing history in a desired operation mode. The receiver apparatus receives broadcast waves of digital broadcasting transmitted from the transmitter apparatus via a transmission path, acquires control information for controlling the recording or the transmission of viewing history information related with the viewing history of content transmitted by broadcast waves, and, on the basis of the acquired control information, controls the recording or the transmission of viewing history information. The present technology is applicable to a television receiver compliant with an IP transmission scheme, for example.

Abstract: A reception apparatus is provided that includes circuitry configured to receive a digital data stream. The circuitry is configured to acquire closed caption information included in the digital data stream. The circuitry is configured to acquire control information including selection information indicating a selection of a specific mode from a plurality of modes for specifying when closed caption text is to be displayed. The circuitry is further configured to output the closed caption text included in the closed caption information for display to a user, at a display time according to the specific mode, based on the selection information included in the control information.

Abstract: There is provided a transmission device, including circuitry configured to receive alert information including metadata related to a predetermined pronunciation of a message. The circuitry is configured to generate vocal information for the message based on the metadata included in the alert information. The circuitry is further configured to transmit emergency information that includes the message and the generated vocal information for the message.

Abstract: There is provided a reception apparatus including circuitry configured to receive region mapping information that includes at least one target region identifier and, for each of the at least one target region identifier, location information associated with the respective target region identifier. The circuitry is further configured to control filtering such that emergency information for a location associated with the reception apparatus is acquired based on the region mapping information.

Abstract: Provided is an information processing device capable of operating in accessibility mode of guaranteeing browsing corresponding to disability or functional degeneration of a body of an operator. A source device checks whether each sink device is in accessibility mode at the time of connection, and determines whether or not metadata for supporting disability (for example, audios, videos, texts, vibration information, or the like) is added to the sink device in the accessibility mode at the time of transmission of original image/audio data. The source device changes a metadata transmission method in accordance with whether the accessibility mode of each sink device is turned on or off.

Abstract: The present technology relates to a transmission device, a transmission method, a reception device, and a reception method that can enhance the accessibility for people with visual disabilities. The transmission device includes: a text-to-speech utterance metadata generation unit that generates text-to-speech utterance metadata about the text-to-speech utterance of display information as the producer intends; an electronic program information generation unit that generates electronic program information including the text-to-speech utterance metadata; and a transmission unit that transmits the electronic program information to the reception device capable of displaying the display information. The present technology can be applied, for example, to a transmitter capable of transmitting a digital broadcast signal.

Abstract: The present technology relates to a transmission device, a transmission method, a reception device, and a reception method with each of which it becomes possible to perform transmission of control information according to an operation form. The reception device receives first data that includes control information, which includes information necessary for channel selection of a service, and transmission sequence information indicating a sequence in which the control information is transmitted and that is transmitted in a transmission sequence corresponding to the transmission sequence information, and controls processing on second data, which includes data of a component included in the service, on the basis of the control information acquired according to the transmission sequence information. The present technology can be applied, for example, to a television receiver.

Abstract: Provided is a reception device configured to receive a broadcast signal on which emergency alert information is superimposed and send out an alert properly. The reception device is configured to include a tuner that tunes and receives a broadcast signal, a demodulator that demodulates a physical layer level of the broadcast signal, and an alert device that sends out an alert of audio, text display, or the like according to the emergency alert information superimposed on the physical layer of the broadcast signal. Since an activation time is short with a simple configuration, an alert is sent out immediately even from a standby state when the emergency alert information is detected. Also, power consumption is small. Thus, even when all of the reception devices in an area where an emergency alert is sent out are concurrently activated, power to be supplied is not short.

Abstract: Emergency alert information is suitably transmitted by utilizing a broadcast service. A preamble section 31 of a transmission frame having a 100 ms interval includes a tuning data section 31A and a reserved bit section 31B, and is made up of a designated total bit length. The tuning data section 31A stores L1 data for tuning to a relevant broadcast channel on the receiving side. Also, the reserved bit section 31B inside the preamble section 31 stores emergency alert information processed by an emergency alert information processing unit 202. In a predetermined message mode, emergency alert information having a predefined message is expressed in a binary format and transmitted in just one frame.
