Reception apparatus, reception method, transmission apparatus, and transmission method

A reception method of a reception apparatus, the reception method comprising:

• receiving broadcast content provided as a pay broadcast service, the broadcast content being transmitted in a scrambled manner;
• acquiring a subscription check application for checking presence of a subscription to the pay broadcast service depending on information indicating presence of the subscription check application, the information being included in control information including information regarding a structure of the broadcast content;
• controlling an operation of the subscription check application;
• acquiring a promotion application in response to a determination that the subscription to the pay broadcast service is not present;
• and
• acquiring a conjunction application in response to a determination that the subscription to the pay broadcast service is present;
• wherein the subscription check application is transmitted in a non-scrambled manner, the promotion application is transmitted in a non-scrambled manner, and the conjunction application is transmitted in a scrambled manner.

A transmission apparatus comprising circuitry configured to:

• generate control information including information regarding a structure of broadcast content to be provided as a pay broadcast service, the control information including information indicating presence of a subscription check application for checking presence of a subscription to the pay broadcast service;
• and
• transmission circuitry configured to
• transmit the control information in a non-scrambled manner and the broadcast content in a scrambled manner,
• transmit the subscription check application,
• transmit a promotion application to be acquired by a reception apparatus based on a determination that the subscription to the pay broadcast service is not present, and
• transmit a conjunction application to be acquired by the reception apparatus based on a determination that the subscription to the pay broadcast service is present;
• wherein the subscription check application is transmitted in a non-scrambled manner, the promotion application is transmitted in a non-scrambled manner, and the conjunction application is transmitted in a scrambled manner.

A transmission method of a transmission apparatus, the transmission method comprising:

• generating, using circuitry, control information including information regarding a structure of broadcast content to be provided as a pay broadcast service, the control information including information indicating presence of a subscription check application for checking presence of a subscription to the pay broadcast service;
• transmitting the control information in a non-scrambled manner together with the broadcast content in a scrambled manner;
• transmitting the subscription check application;
• transmitting a promotion application to be acquired by a reception apparatus based on a determination that the subscription to the pay broadcast service is not present;
• and
• transmitting a conjunction application to be acquired by the reception apparatus based on a determination that the subscription to the pay broadcast service is present;
• wherein the subscription check application is transmitted in a non-scrambled manner, the promotion application is transmitted in a non-scrambled manner, and the conjunction application is transmitted in a scrambled manner.
