Application Controller for Digital Broadcasting Resource Termination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a technological solution to effectively limit the use of broadcast resources by specific applications in digital broadcasting environments, where applications obtained via different means, such as the Internet, may not be restricted from using these resources.
Innovation Solution
A reception apparatus and method that includes a reception unit for digital broadcasting signals, an application obtaining unit for applications capable of requesting broadcast resources, a control information obtaining unit for controlling application operations, and an application controller to manage the use of broadcast resources based on obtained control information, ensuring that only permitted applications access and utilize these resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If applications are obtained via Internet distribution instead of broadcast service, then application availability and versatility are improved, but unauthorized use of broadcast resources occurs
Solution Approach 1:
The system performs preliminary verification by obtaining control information associated with the application before the application executes. This control information contains authorization data that is checked in advance to determine whether the application is permitted to use broadcast resources, preventing unauthorized access before it occurs.
Solution Approach 2:
Control information acts as an intermediary between the application and broadcast resources. The reception apparatus uses this control information to mediate and regulate whether the application can access broadcast resources, creating a controlled interface that enables legitimate use while blocking unauthorized access.
2Reliability
If broadcast resources are restricted to maintain resource integrity, then resource security is improved, but application functionality is reduced
Solution Approach 1:
The system dynamically adjusts resource access permissions based on the specific application and its associated control information. Rather than imposing static restrictions, the reception apparatus evaluates each application's authorization status and grants or denies access accordingly, allowing legitimate applications full functionality while blocking unauthorized ones.
Solution Approach 2:
The system changes the authorization parameter of broadcast resource access based on control information verification. When control information indicates authorized status, the access parameter is set to permit use; when unauthorized, the parameter is changed to restrict access, thereby maintaining resource integrity without unnecessarily limiting legitimate applications.
3Reliability
If control mechanisms are implemented to verify application authorization, then resource security is improved, but system complexity increases
Solution Approach 1:
The control information structure serves multiple functions simultaneously: it identifies the application, verifies authorization status, and provides guidance for resource access. This multi-functional approach consolidates what could be separate complex verification systems into a single unified mechanism, reducing overall system complexity while maintaining security.

AI summary
[Object] The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method capable of limiting use of broadcast resources by a predetermined application. [Solving Means] There is provided a reception apparatus including: a control information obtaining unit that obtains first control information for controlling an operation of a first application, the first application being capable of requesting use of a broadcast resource transmitted via a digital broadcasting signal; and an application controller that controls, when the first application requests use of the broadcast resource, the use of the broadcast resource by the first application on the basis of the first control information.
