Abstract

The present technology relates to a transmission device, a transmission method, a reception device, and a reception method with each of which it becomes possible to perform transmission of control information according to an operation form. The reception device receives first data that includes control information, which includes information necessary for channel selection of a service, and transmission sequence information indicating a sequence in which the control information is transmitted and that is transmitted in a transmission sequence corresponding to the transmission sequence information, and controls processing on second data, which includes data of a component included in the service, on the basis of the control information acquired according to the transmission sequence information. The present technology can be applied, for example, to a television receiver.

Claims

1. A transmission device comprising:

a generation unit configured to generate first data including control information, which includes information necessary for channel selection of a service, and transmission sequence information indicating a sequence in which the control information is transmitted, and

a transmission unit configured to transmit the first data in a transmission sequence corresponding to the transmission sequence information along with second data including data of a component included in the service.

2. The transmission device according to claim 1, wherein the transmission sequence information includes

class information including a class ID for identification of a sequence of the control information, and

version information indicating a version of the control information in each sequence.

3. The transmission device according to claim 2, wherein the class ID is for identification of the control information in each transmission cycle as a different transmission sequence, and

the transmission unit transmits the first data in such a manner that the control information is transmitted in a transmission cycle corresponding to a transmission sequence.

4. The transmission device according to claim 3, wherein it is identified with the class ID that control information to be updated dynamically in a reception device configured to perform channel selection of the service and control information to be updated statically in the reception device are in different transmission sequences, and

the transmission unit transmits the first data in such a manner that a transmission cycle of the control information to be updated dynamically becomes shorter than a transmission cycle of the control information to be updated statically.

5. The transmission device according to claim 2, wherein the control information includes, for each service, one or a plurality of pieces of information to provide various functions, and

the one or the plurality of pieces of information is associated to each sequence of the control information.

6. The transmission device according to claim 2, wherein the control information includes, for each service, one or a plurality of pieces of information to provide various functions,

the one or the plurality of pieces of information is associated to sequences of the control information, and

priority in updating according to the class ID is assigned to the sequences of the control information.

9. The transmission device according to claim 2, wherein the first data is transmitted by an IP packet or a UDP packet.

10. The transmission device according to claim 1, wherein the transmission sequence information includes information for identification of a service provider providing a service.
