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

A reception method operating in a reception device, said method comprising:

• receiving, by circuitry of the reception device, first signaling data including control information having information necessary for channel selection of a service;
• and
• controlling, by the circuitry of the reception device, processing on second signaling data including data of a component included in the service;
• wherein the first signaling data includes a group ID indicating a transmission sequence of the control information, and information indicating a number of groups,
• wherein the first signaling data is received in an IP packet included in a physical layer frame, and the physical layer frame includes information indicating that the physical layer frame includes the first signaling data,
• wherein the first signaling data is low level signaling (LLS) data and the second signaling data is service layer signaling (SLS) data.

A transmission method operating in a transmission device, said method comprising:

• generating, by circuitry of the transmission device, first signaling data including control information having information necessary for channel selection of a service and second signaling data including data of a component included in the service;
• wherein the first signaling data includes a group ID indicating a transmission sequence of the control information, and information indicating a number of groups,
• wherein the first signaling data is transmitted in an IP packet included in a physical layer frame, and the physical layer frame includes information indicating that the physical layer frame includes the first signaling data,
• wherein the first signaling data is low level signaling (LLS) data and the second signaling data is service layer signaling (SLS) data.
