Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data broadcast is used to transmit information, then various information can be displayed, but the transmission capacity is limited and high-definition screen display cannot be achieved
Solution Approach 1:
The patent combines data broadcast reception with broadband network communication capabilities in a single digital broadcast receiver. The receiver integrates both data broadcast tuning units and broadband communication interfaces, allowing it to receive limited data via broadcast while simultaneously accessing unlimited data resources through broadband networks, thereby achieving both information display and high-definition screen capabilities
Solution Approach 2:
The digital broadcast receiver is designed with multi-functional capabilities including data broadcast reception, broadband network communication, application execution, and screen display. This universal device can perform multiple functions: receiving data broadcast, accessing broadband resources, executing applications, and providing both standard and high-definition screen outputs, eliminating the need for separate dedicated devices
2Device complexity
If data broadcast with limited bandwidth is used, then communication is simple, but highly functional effects and valuable additional functions cannot be executed
Solution Approach 1:
The patent segments data acquisition into two independent channels: data broadcast reception for basic information and broadband network access for additional resources. This segmentation allows the system to maintain simple broadcast communication while separately leveraging broadband capabilities for enhanced functionality, application distribution, and content delivery without complicating the core broadcast reception mechanism
Solution Approach 2:
The digital broadcast receiver acts as an intermediary that bridges data broadcast and broadband network resources. It receives data broadcast information, then uses broadband communication to fetch additional applications, content, and resources, mediating between the limited broadcast channel and the unlimited broadband network to deliver comprehensive functionality

AI summary
The present invention provides a digital broadcast receiver capable of executing functions having higher added values. The broadcast receiver receives a broadcast wave of a digital broadcast service, controls an operation including activation and end of an application that is in cooperation with a broadcast program based on application-related information, and selects control relating to reactivation of the application based on a user's operation. If activation of the application is requested after the end of the application, the broadcast receiver controls the reactivation or non-reactivation of the application in accordance with the selection of control by the user.
