The present technology relates to a transmitting device, a transmitting method, a receiving device, and a receiving method, which are capable of improving immediacy and flexibility of an alert.

A transmitting device generates transmission data in which an index associated with predetermined process-related information in a relevant table in which process-related information related to an output process of outputting an alert on a receiving side is registered in association with an index is included in data of a physical layer, the relevant table being included in data of a higher layer higher than the physical layer and supplied, and transmits the transmission data. The receiving device obtains a relevant table, receives transmission data, and acquires an index included in data of a physical layer from the transmission data. Then, the receiving device executes an output process corresponding to process-related information associated with the index included in the data of the physical layer in the relevant table. For example, the present technology can be applied in a case where an emergency alert is provided in television broadcasting.

The present technology relates to a transmitting apparatus, a transmitting method, a receiving apparatus, and a receiving method that facilitate tuning setting.

A transmitting apparatus generates and transmits transmission data including an index in data of a physical layer, the index being associated with predetermined processing-related information in a relation table in which processing-related information related to setting processing of tuning on a receiving side is registered in association with an index representing a region to be subjected to the setting processing corresponding to the processing-related information and provided as being included in data of an upper layer higher than the physical layer. A receiving apparatus acquires the relation table, while receiving the transmission data, and acquires the index included in the data of the physical layer from the transmission data. Then, the receiving apparatus executes setting processing corresponding to the processing-related information associated with the index included in the data of the physical layer in the relation table. The present technology can be applied to, for example, setting of tuning, such as television broadcasting.

A method of validating a signal received by a radio from a radio station includes determining a strength of the signal as received by the radio, ascertaining a frequency of the signal, and calculating a first distance between the radio and the radio station dependent upon the strength of the signal as received by the radio. A location and a broadcast range of the radio station are found in a database based on the frequency of the signal, A second distance between the radio and the radio station is computed based on a known location of the radio and the location of the radio station as found in the database. The radio station is validated only if the first distance and the second distance are within a margin of error and if the second distance is within the broadcast range of the radio station.
