Broadcast signal receiving device, broadcast signal receiving method

Abstract

The objective is to provide a broadcast signal receiving device and a broadcast signal receiving method that have a function to indicate the types of DRM that are supported. [Solution] This embodiment is a broadcast signal receiving device in which, based on first information included in the control signal of a broadcast wave that broadcasts a program, an application consisting of application data attached to the program that exists in the broadcast wave, and when the acquired application acquires content to which security management information is applied, including at least video, by communication, the security management information processing means provides the application with the type of security management information that it supports.

Claims

1. An analysis unit analyzes the transmission control signals separated from the broadcast signal that receives the broadcast wave for broadcasting the program, and obtains control information from the transmission control signals that relates to application data which will be added to the program to perform specific processing. An application control unit identifies the location of application data present in the broadcast signal based on the aforementioned control information, The application control unit includes an application data receiving processing unit that receives the application data at a location identified within the broadcast signal, The application data receiving processing unit manages an application engine consisting of application data received by the application engine, A content receiving processing unit that acquires content via communication, A security management information processing unit applies security management information that supports the type of content to the content acquired through the communication, among multiple types of security management information that support the protection of the aforementioned content according to its type. It is equipped with, The application engine provides the application with information on the types of security management information supported by the security management information processing unit. The aforementioned application is This involves determining whether there is a type of security management information provided by the application engine that is necessary for performing the specific processing. If a first type exists, the first content is obtained from the first distribution destination of the first content to which the security management information of the first type applies, via the content receiving processing unit, and the first identification process is performed. If the first type does not exist, determine whether the second type exists. If the second type exists, the second content is obtained from the second distribution destination of the second content to which the security management information of the second type applies, via the content receiving processing unit, and the second identification process is performed. If the second type does not exist, a notification will be sent to the display screen indicating that the service is not supported. Broadcast signal receiving device.

2. The analysis unit analyzes the transmission control signals separated from the broadcast signal that receives the broadcast wave for broadcasting the program, and obtains control information from the transmission control signals that relates to application data which will be added to the program to perform specific processing. The application control unit identifies the location of the application data present in the recorded broadcast signal based on the control information. The application data receiving processing unit receives the application data at the location identified by the application control unit within the broadcast signal. The application engine manages the application consisting of the application data received by the application data receiving processing unit. The content receiving processing unit acquires the content via communication. The security management information processing unit applies, from among multiple types of security management information that support the protection of the content according to its type, the security management information that supports the type of content to the content acquired through the communication. The application engine provides the application with information on the types of security management information supported by the security management information processing unit. The application determines whether there is a type of security management information provided by the application engine that is necessary for performing the specific processing. If a first type exists, the first content is obtained from the first distribution destination of the first content to which the security management information of the first type applies, via the content receiving processing unit, and the first identification process is performed. If the first type does not exist, determine whether the second type exists. If the second type exists, the second content is obtained from the second distribution destination of the second content to which the security management information of the second type applies, via the content receiving processing unit, and the second identification process is performed. A broadcast signal reception method that, if the second type described above does not exist, notifies the user to display a message on the display screen indicating that the service is not supported.
