Abstract

The present technology relates to a reception device, a reception method, a transmission device, and a transmission method, which are capable of acquiring a component configuring a service efficiently, appropriately, and easily.

A reception device acquires second metadata including first and second flags, the first flag indicating whether or not it is possible to acquire components configuring a service through only first metadata, the second flag indicating whether or not there is a stream of a component transmitted from a server on the Internet by way of communication among the streams of the components configuring the service, the first metadata including information related to a stream of a component transmitted by way of broadcasting through a broadcast wave of digital broadcasting using an Internet Protocol (IP) transmission scheme, acquires the first metadata based on the second metadata, accesses the stream of the component transmitted by way of the broadcasting based on the first metadata, and controls reproduction of the component. The present technology can be applied, for example, to a television receiver.

Claims

1-15. -15. (canceled)

16. A reception device, comprising:

circuitry configured to

acquire second metadata including a flag, the flag indicating whether or not there is a component stream transmitted from a server via the Internet for a service;

acquire first metadata based on the second metadata, the first metadata including information related to a component stream for the service transmitted in a broadcast signal using an Internet Protocol (IP) transmission scheme; and

access the component stream transmitted in the broadcast signal based on the first metadata, and control reproduction of the component stream transmitted in the broadcast signal.

17. The reception device according to claim 16,

wherein, when the second flag indicates that there is no component stream transmitted via the Internet, the circuitry accesses the component stream transmitted in the broadcast signal and controls the reproduction of the component stream transmitted in the broadcast signal based on the first metadata.

18. The reception device according to claim 16,

wherein, when the second flag indicates that there is the component stream transmitted via the Internet, the circuitry acquires third metadata for managing reproduction of the component stream transmitted via the Internet, and

the circuitry accesses the component stream transmitted in the broadcast signal and the component stream transmitted via the Internet and controls reproduction of the component streams transmitted in the broadcast signal and via the Internet based on the first metadata and the third metadata.

19. The reception device according to claim 16,

wherein the first metadata is first signaling data transmitted through a layer higher than an IP layer in a protocol stack of the IP transmission scheme, and

the second metadata is second signaling data transmitted through a layer lower than the IP layer in the protocol stack of the IP transmission scheme.

20. The reception device according to claim 19,

wherein the component stream transmitted in the broadcast signal and a stream of the first signaling data are transmitted through a Real-time Object Delivery over Unidirectional Transport (ROUTE) session extended from a File Delivery over Unidirectional Transport (FLUTE).

21. The reception device according to claim 20,

wherein the service includes the component stream transmitted in the broadcast signal and the first signaling data to which a common IP address is allocated, and

the component stream transmitted in the broadcast signal and the first signaling data are transmitted through different Base Band Packet (BBP) streams.

22. The reception device according to claim 19,

accessing, by the circuitry, the component stream transmitted in the broadcast signal based on the first metadata, and controlling reproduction of the component stream transmitted in the broadcast signal.

26. A transmission device, comprising:

circuitry configured to

generate second metadata including a flag, the flag indicating whether or not there is a component stream transmitted from a server via the Internet for a service, the first metadata including information related to a component stream for the service transmitted in a broadcast signal using an Internet Protocol (IP) transmission scheme; and

transmit the generated second metadata.

27. The transmission device according to claim 26,

wherein the first metadata is first signaling data transmitted through a layer higher than an IP layer in a protocol stack of the IP transmission scheme, and

the second metadata is second signaling data transmitted through a layer lower than the IP layer in the protocol stack of the IP transmission scheme.

28. The transmission device according to claim 27,

wherein the component stream transmitted in the broadcast signal and a stream of the first signaling data are transmitted through a Real-time Object Delivery over Unidirectional Transport (ROUTE) session extended from a File Delivery over Unidirectional Transport (FLUTE).

29. The transmission device according to claim 28,

wherein the service includes the component stream transmitted in the broadcast signal and the first signaling data to which a common IP address is allocated, and

the component stream transmitted in the broadcast signal and the first signaling data are transmitted through different Base Band Packet (BBP) streams.

30. A transmission method of a transmission device, comprising the steps of:
