Receiving device, receiving method, transmitting device, and transmitting method

A receiving device, comprising:

• a receiver configured to receive a broadcast stream, the broadcast stream including a plurality of services, each of the plurality of services including one or a plurality of components and a first control signal transmitted by a unidirectional transport session;
• and
• processing circuitry configured to process the one or the plurality of components constituting a particular service of the plurality of services included in the broadcast stream, and process the first control signal of the particular service received from signals transmitted by the unidirectional transport session according to an Internet Protocol (IP) address, wherein
• each of the plurality of services is associated with a different IP address that is contained in packets of the one or the plurality of components and the first control signal of the respective service, and in an IP layer, wherein no transport layer exists between the IP layer and a physical layer in a protocol stack.

A receiving method comprising:

• receiving a broadcast stream, the broadcast stream including a plurality of services, each of the plurality of services including one or a plurality of components and a first control signal transmitted by a unidirectional transport session;
• and
• processing the one or the plurality of components constituting a particular service of the plurality of services included in the broadcast stream, and processing the first control signal of the particular service received from signals transmitted by the unidirectional transport session according to an Internet Protocol (IP) address, wherein
• each of the plurality of services is associated with a different IP address that is contained in packets of the one or the plurality of components and the first control signal of the respective service, and in an IP layer, wherein no transport layer exists between the IP layer and a physical layer in a protocol stack.

A non-transitory computer readable storage medium storing instructions, which, when being executed by processing circuitry of a receiving device, cause the processing circuitry to perform a method comprising:

• receiving a broadcast stream, the broadcast stream including a plurality of services, each of the plurality of services including one or a plurality of components and a first control signal transmitted by a unidirectional transport session;
• and
• processing the one or the plurality of components constituting a particular service of the plurality of services included in the broadcast stream, and processing the first control signal of the particular service received from signals transmitted by the unidirectional transport session according to an Internet Protocol (IP) address, wherein
• each of the plurality of services is associated with a different IP address that is contained in packets of the one or the plurality of components and the first control signal of the respective service, and in an IP layer, wherein no transport layer exists between the IP layer and a physical layer in a protocol stack.
