Solution Overview

Problem

Users face difficulties in accessing desired datacast information from multiple broadcast stations as existing systems only display datacast information from the currently viewed station, making it hard to find specific information without manual channel switching.

Innovation Solution

A datacast information controller that splits broadcast radio waves, compares received datacast information for specified keywords, and instructs display of matching information on connected devices, allowing users to search and view desired information across multiple stations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If datacast information is displayed only from the currently viewed broadcast station, then the display system remains simple, but users cannot access desired information from other stations without manual channel switching

Engineering Contradiction:

Improveease of accessing datacast informationVSAvoidcomplexity of datacast information processing

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges datacast information from multiple broadcast stations into a unified display interface. The notification display unit combines datacast information from the currently viewed station and other stations, allowing users to access information from multiple sources without manually switching channels, thus improving ease of operation while managing complexity through integrated processing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display system is designed to handle multiple functions: displaying datacast information from the currently viewed station, displaying datacast information from other stations, and providing notification displays for new or updated information. This multi-functional approach allows the system to serve as a comprehensive information access point across multiple broadcast stations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of information

If the system monitors datacast information from multiple broadcast stations, then users can find desired information more easily, but the information processing complexity increases

Engineering Contradiction:

Improvecompleteness of datacast information accessVSAvoidcomplexity of information comparison and notification

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by acquiring and storing datacast information from multiple broadcast stations in advance, before user requests. The management unit stores information including identification information and content, so that when users view a station, the relevant data is already prepared and can be quickly retrieved and displayed without real-time processing delays.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a management unit as an intermediary between broadcast stations and the display interface. This management unit handles the complex tasks of acquiring, storing, and managing datacast information from multiple stations, then providing simplified access to the display units. It acts as a mediator that manages the complexity internally while presenting a simple interface to users.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of time

If manual channel switching is required to find specific datacast information, then the system remains simple, but user time and effort increase

Engineering Contradiction:

Improvetime to locate desired informationVSAvoidease of information search

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The patent adds a new dimension to information access by displaying datacast information from multiple broadcast stations simultaneously in a unified notification display interface. Instead of requiring users to switch channels (one-dimensional sequential access), the system presents information from multiple stations together (multi-dimensional parallel access), allowing users to find desired information quickly without manual channel switching.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Disclosed is that datacast information from at least one or more broadcast station is searched for information that a user wants to view and searched information is presented to the user in a manner desired by the user. A datacast information controller includes a content storage unit storing datacast information obtained by splitting a broadcast radio wave, a keyword comparison unit determining whether the datacast information includes a specified keyword, a broadcast information storage unit storing datacast information that includes the keyword detected beforehand, a broadcast information comparison unit comparing datacast information determined to include the keyword with datacast information being stored in the broadcast information storage unit and including the same keyword, and a notification instruction unit instructing to display the determined datacast information in a specified manner of notification if the comparison shows that the determined datacast information does not match the datacast information including the same keyword.
