COMMUNICATION APPARATUS, METHOD OF TRANSMITTING COMMUNICATION CONTROL DATA, AND METHOD OF RECEIVING COMMUNICATION CONTROL DATA

摘要

Transmission frequency information in units of component, the component being a data element contained in one broadcast delivery service and allowed for independent delivery, is supplied to a user terminal so that the user terminal can execute reception setting in units of component. A data transmission device transmits, to the user terminal, metadata recording transmission frequency information in units of component that is constituent data of a broadcast delivery service and corresponds to a data element allowed for independent delivery to the user terminal, such as units of component constituted by image data having a particular resolution, audio data or subtitle data in a particular language, or other types of data. The user terminal corresponding to a receiving device executes a setting process for setting a reception frequency allowing reception of a component intended to be received based on transmission frequency information recorded in units of component in the metadata received from the data transmission device.
