Reception apparatus, reception method, transmission apparatus and transmission method

A reception method for a reception apparatus, comprising:

• selecting a channel of digital broadcasting using an IP (Internet Protocol) transmission method, the channel being identifiable by an IP address;
• in response to control information received from the channel of the digital broadcasting for triggering acquisition of an application,
• obtaining, by circuitry of the reception apparatus, application control information for the application from the channel of the digital broadcasting or from communication through a network, and
• obtaining, by the circuitry of the reception apparatus, signaling information for the channel from the channel of the digital broadcasting;
• controlling, by the circuitry of the reception apparatus, acquisition of a whole or a portion of the application that is identified in the application control information using the digital broadcasting or the communication through the network as indicated in the signaling information after obtaining the application control information and the signaling information;
• and
• executing the application after the application is acquired by the reception apparatus.

A transmission apparatus, comprising:

• circuitry configured to
• generate a stream to be transmitted in a channel of digital broadcasting using an IP (Internet Protocol) transmission method, the channel being identifiable by an IP address, and the stream including control information for triggering acquisition of an application;
• generate signaling information for the channel, the signaling information indicating whether a whole or a portion of the application that is identified in application control information for the application is to be delivered using the digital broadcasting or communication through a network after transmission of the application control information and the signaling information;
• transmit the signaling information and the stream in the channel of the digital broadcasting identifiable by the IP address using the IP transmission method;
• and
• transmit the whole or the portion of the application using the digital broadcasting when the signaling information indicates that the whole or the portion of the application is to be delivered using the digital broadcasting.
