Television Receiver Optical Character Recognition Hypertext Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack the ability to effectively analyze video images to provide users with additional information related to text content in television broadcasts, limiting the interactive and informative experience for viewers.
Innovation Solution
A television receiver equipped with optical character recognition (OCR) and a hypertext link generator that identifies text in video images and connects to a network based on context, allowing users to access additional content such as web pages or search engines, using a device like the Sony PlayStation 3 with integrated OCR and network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If optical character recognition is applied to video images to identify text, then users can access additional information related to text content, but the device complexity increases due to integration of OCR and hypertext link generation components
Solution Approach 1:
The patent combines multiple functions (OCR text identification, context analysis, hypertext link generation, and network connectivity) into a single integrated television receiver system. This merging approach enables the device to transform passive video content into interactive information-accessible content while managing complexity through unified architecture.
Solution Approach 2:
The television receiver is designed with multi-functionality, serving both traditional video display purposes and advanced information retrieval functions. The system can identify text in various contexts (subtitles, on-screen graphics, text overlays) and generate appropriate hypertext links, making it a universal platform for both entertainment and information access.
2Productivity
If context-based default target selection is implemented to improve user experience, then information retrieval efficiency increases, but the processing requirements and device complexity increase
Solution Approach 1:
The system performs preliminary context analysis of the video image content before generating hypertext links. By pre-identifying the context category (subtitles, on-screen graphics, text overlays) and selecting appropriate default targets in advance, the system reduces processing time when users interact with the content, thereby improving information retrieval efficiency.
Solution Approach 2:
The patent introduces context analysis as an intermediary process between text identification and hypertext link generation. This intermediary layer categorizes the text context and selects appropriate default targets, simplifying the overall processing by breaking down the complex task into manageable stages with clear decision points.
3Adaptability or versatility
If text interaction capabilities are added to television receivers, then user engagement and viewing experience are enhanced, but the ease of operation may be reduced due to additional interaction modes
Solution Approach 1:
The system automatically performs text identification and context analysis without requiring user intervention. The television receiver proactively generates hypertext links based on the detected text content, allowing users to simply select from pre-generated options rather than manually searching or configuring settings, thus maintaining ease of operation while enhancing versatility.
