Transmission device, transmission method, reception device, and reception method

A transmission method in a transmission device, comprising:

• generating, by circuitry of the transmission device, first data including (i) control information, which includes information necessary for channel selection of a service, and (ii) a transmission sequence information item indicating a sequence in which the control information is transmitted, the transmission sequence information including:
• (a) a class ID for identification of a sequence of the control information, the class ID including a provider ID for identification of a provider of the service and a delivery class ID for identification of transmission sequences with different time sequences, and
• (b) version information indicating a version of the control information in each sequence;
• and
• transmitting, by the circuitry of the transmission device, the first data according to the transmission sequence information.

A reception device comprising:

• a receiver configured to receive 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 in a transmission sequence corresponding to the transmission sequence information;
• and
• processing circuitry configured to control processing on second data, which includes data of a component included in the service, based on the control information acquired according to the transmission sequence information,
• wherein the transmission sequence information includes:
• (a) a class ID for identification of a sequence of the control information, the class ID including a provider ID for identification of a provider of the service and a delivery class ID for identification of transmission sequences with different time sequences, and
• (b) version information indicating a version of the control information in each sequence.

A reception method in a reception device, comprising:

• receiving, by circuitry of the reception device, 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
• controlling, with the circuitry of the reception device, processing on second data, which includes data of a component included in the service, based on the control information acquired according to the transmission sequence information,
• wherein the transmission sequence information includes:
• (a) a class ID for identification of a sequence of the control information, the class ID including a provider ID for identification of a provider of the service and a delivery class ID for identification of transmission sequences with different time sequences, and
• (b) version information indicating a version of the control information in each sequence.
