Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data broadcast is used to transmit information, then various information such as weather forecast, news, and recommended programs can be displayed, but the limited electric wave band prevents high-definition screen display and highly functional effects
Solution Approach 1:
The patent segments the information transmission into two parts: basic information is transmitted via data broadcast through the limited electric wave band, while enhanced information including high-definition content and additional functional effects is transmitted separately through broadband networks, allowing each channel to operate within its capabilities without compromising the other
Solution Approach 2:
The patent adds another dimension to the information transmission system by introducing broadband network connectivity alongside traditional data broadcast. This creates a multi-dimensional transmission architecture where information can be delivered through multiple channels simultaneously, bypassing the limitation of a single constrained bandwidth channel
2Reliability
If data broadcast with limited electric wave band is used, then broadcast reception is maintained, but execution of useful functions with high added values becomes difficult
Solution Approach 1:
The patent makes the broadcast receiver universal by equipping it with multiple communication interfaces: traditional data broadcast reception for basic functionality and broadband network connectivity for enhanced functions. This multi-functional design allows the receiver to adapt to various service requirements, from simple information display to complex interactive applications, without sacrificing broadcast reception reliability

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.
