Broadcast Application Control via XML-AIT Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers face challenges in managing and controlling the behavior of broadcast-excluding managed applications, which are provided by third parties, leading to issues with service quality and resource usage.
Innovation Solution
An information processing system and method that utilize an XML-AIT and section AIT to control the activation, usage permissions, and operation of broadcast-excluding managed applications, including electronic signatures for authentication and dynamic permission management, allowing service providers to manage application behavior and resource access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If broadcast-excluding managed applications are allowed to operate freely, then application functionality and user choice are improved, but service quality control and resource management deteriorate
Solution Approach 1:
The patent introduces an XML-AIT (Application Information Table) as an intermediary data structure that mediates between the application provider and the service provider. The XML-AIT contains application information and control parameters that allow service providers to manage and control broadcast-excluding managed applications while maintaining their functionality. This intermediary enables detailed control of application behavior without restricting application versatility.
2Reliability
If detailed control of application behavior is implemented, then service quality is improved, but system complexity increases
Solution Approach 1:
The patent implements detailed control of application behavior by changing parameters within the XML-AIT structure. Service providers can control various aspects of application execution by setting specific parameters such as activation conditions, resource access permissions, and operational constraints. This approach allows fine-grained control without requiring fundamental changes to the system architecture, thereby managing complexity.
3Adaptability or versatility
If third-party applications are permitted, then application diversity is improved, but security and authorization management deteriorate
Solution Approach 1:
The patent implements preliminary authorization by requiring service providers to pre-approve and register third-party applications through the XML-AIT mechanism. Before applications can execute, they must be authorized and their parameters configured in advance. This preliminary action ensures that only secure and authorized applications run on the system, mitigating security risks while maintaining application diversity.

AI summary
There is provided an information processing apparatus including a broadcast receiving unit and a controller. The broadcast receiving unit is configured to be capable of receiving a broadcast. The controller is configured to acquire a first application information table by communication, the first application information table storing at least first usage permission information indicating a usage permission range of a resource of the broadcast by an application using the resource, to control an operation of the application, and to acquire a second application information table storing at least second usage permission information indicating the usage permission range of the resource by the application by using the broadcast receiving unit during execution of the application, to control the operation of the application.
