Reception Apparatus HTML Document Management Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital TV broadcasting in the United States using ATSC 2.0, HTML documents cannot set operation modes to enable or restrict specific processes, leading to unauthorized processes being executed, which compromises user safety.
Innovation Solution
A reception apparatus manages HTML documents to permit or restrict processes based on whether they are managed by a broadcasting organization or not, using trigger information in PCR packets to control the execution of data broadcast HTML documents and Web page HTML documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HTML documents are used for data broadcast service in ATSC 2.0, then the service can be implemented with simple document transitions, but operation modes cannot be set to enable or restrict specific processes, leading to unauthorized processes being executed
Solution Approach 1:
The patent segments HTML documents into two distinct types: data broadcast HTML documents (from authorized broadcasting organizations) and web page HTML documents (from unauthorized sources). This segmentation allows the system to apply different management modes to each type, enabling process execution for authorized documents while restricting it for unauthorized ones, thus resolving the contradiction between service versatility and user safety
Solution Approach 2:
The patent applies local quality by setting different management modes (enabled or restricted) for specific processes based on the source of the HTML document. Authorized broadcasting organization documents receive an enabled management mode allowing specific processes, while unauthorized web page documents receive a restricted management mode preventing those same processes, thereby maintaining reliability while preserving adaptability
2Reliability
If operation modes are set to enable specific processes for authorized documents, then user safety is improved, but the complexity of managing different management modes increases
Solution Approach 1:
The patent implements self-service by automatically determining the management mode based on the source of the HTML document. The system autonomously identifies whether a document comes from an authorized broadcasting organization or an unauthorized web source and applies the appropriate management mode without requiring manual configuration, thus improving user safety while minimizing the complexity burden on users

AI summary
This invention relates to a reception apparatus, a reception method, and a program capable of preventing any process not intended by a user from being performed where a data broadcast service is implemented through transitions of documents. The reception apparatus acquires a description document described in a predetermined computer language for displaying a type of content different from AV content; determines whether the acquired description document is managed by a broadcasting organization broadcasting the AV content or by a business operator other than the broadcasting organization; and controls execution of the acquired description document in accordance with the result of the determination. This technology may be applied when data broadcasting is implemented in the United States for example.
