Communication device, communication control data transmitting method, and communication control data receiving method

A communication device comprising:

• a receiver circuitry configured to receive metadata that records, independently for first and second components of a service, (i) first and second delivery mode information including transmission frequency information indicating a frequency band for transmitting a respective one of the first and second components, (ii) access information, and (iii) transmission area information including a delivery area of the respective one of the first and second components, wherein for each of the first and second components, the metadata corresponds to a data element constituting image data, audio data, or subtitle data, wherein the first component is different from the second component, and the first delivery mode information is different from the second delivery mode information;
• and
• a data processing circuitry configured to execute a process using the metadata for receiving the first and second components of the service.

A communication control data transmitting method performed by a data transmission device, the method comprising:

• using data processing circuitry, generating, or acquiring from a storage, metadata that records, independently for first and second components of a service, (i) first and second delivery mode information including transmission frequency information indicating a frequency band for transmitting a respective one of the first and second components, (ii) access information, and (iii) transmission area information indicating a delivery area of the respective one of the first and second components, wherein for each of the first and second components, the metadata corresponds to a data element constituting image data, audio data, or subtitle data, wherein the first component is different from the second component, and the first delivery mode information is different from second delivery mode information;
• and
• using communication circuitry, transmitting the metadata to the user terminal for receiving the first and second components of the service.

A communication control data receiving method performed by a data reception device, the method comprising:

• using communication circuitry, receiving metadata that records, independently for first and second components of a service, (i) first and second delivery mode information including transmission frequency information indicating a frequency band for transmitting a respective one of the first and second components, (ii) access information, and transmission area information indicating a delivery area of the respective one of the first and second components, wherein for each of the first and second components, the metadata corresponds to a data element constituting image data, audio data, or subtitle data, wherein the first component is different from the second component, and the first delivery mode information is different from second delivery mode information;
• and
• using data processing circuitry, executing a process using the metadata for receiving the first and second components of the service.
