Television Broadcast Receiver Keyword Extraction for Web Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for combining television broadcast reception and internet search functionality are not user-friendly, as they require manual input of query strings and are inconvenient when program information changes, leading to inefficient searching based on television program information.
Innovation Solution
A television broadcast receiving device with integrated units for receiving and decoding broadcast signals, extracting keywords from program information, and generating acquisition objective information to directly search webpages related to selected programs on connected shopping sites, allowing seamless integration of program information with internet search functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually inputs query strings to search for program-related information, then the search function can be implemented, but the operation becomes complex and inconvenient when program information changes
Solution Approach 1:
The television broadcast receiving device automatically extracts keywords from program information and generates search queries without requiring manual user input. The device serves itself by autonomously obtaining program information, extracting relevant keywords, and constructing search requests to query webpages, thereby eliminating the need for users to manually input complex query strings.
Solution Approach 2:
The device performs preliminary extraction of keywords from program information before the search is actually needed. By pre-processing the program information to identify and extract relevant keywords in advance, the system prepares the search queries ready for execution, reducing the operational steps required at the moment of searching.
2Adaptability or versatility
If the system uses fixed query string formats for searching, then the search process is simple, but it cannot adapt when program information or website configurations change
Solution Approach 1:
The system dynamically adapts its search process based on the actual program information received. Instead of using fixed query string formats, the device extracts keywords from the actual program data and generates search queries that adapt to changes in program information. This dynamic approach allows the system to automatically adjust to different program types, titles, and content while maintaining search effectiveness.
3Ease of operation
If the device integrates multiple functions (broadcast reception, program information processing, and web search), then user convenience increases, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions including television broadcast reception, program information decoding, keyword extraction, and web page searching into a single integrated device. The television broadcast receiving device merges these previously separate operations into one unified system, allowing users to perform searches related to broadcast programs without needing separate devices for each function.
Solution Approach 2:
The television broadcast receiving device is designed with multi-functionality, serving as both a broadcast receiver and an autonomous search engine. The device can decode program information from broadcasts, extract relevant keywords, and automatically search for related web pages, making it a universal device that handles multiple tasks that would traditionally require separate tools.
