Program Ancillary Data Extraction for Digital Broadcast Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital broadcast systems face limitations in providing sufficient information to viewers due to constraints in signaling systems, making it difficult to offer attractive services, especially in analog broadcast systems, whereas digital systems have the potential for transmitting larger quantities of information but struggle with facilitating access to this information.
Innovation Solution
A program ancillary data processing device that extracts and displays relevant information about commodities or services appearing in a digital picture program, using a program ancillary data extraction unit and display control unit to track scene-based access events, allowing for the determination of popular items based on audience interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the amount of information transmitted in digital broadcast systems is increased, then the quantity of information available to viewers is improved, but the accessibility and ease of access to this information deteriorates
Solution Approach 1:
The patent segments the large quantity of program ancillary data into scene-based units, where each scene contains relevant information about commodities or services appearing in that specific scene. This segmentation allows the system to manage and present information in manageable portions, improving accessibility while maintaining the comprehensive quantity of information available across all scenes.
Solution Approach 2:
The patent introduces a program ancillary data processing device as an intermediary between the broadcast system and the viewer. This device extracts, processes, and presents relevant information from the large dataset of program ancillary data, acting as a mediator that makes the information accessible and useful to viewers without requiring them to manually search through vast amounts of data.
2Adaptability or versatility
If program ancillary data is extracted and processed for each scene, then the relevance and usability of information is improved, but the processing complexity and device requirements increase
Solution Approach 1:
The patent applies extraction by removing and isolating only the relevant program ancillary data related to commodities or services from the broader dataset. The processing device extracts specific information about products, services, and their associated data for each scene, filtering out unnecessary information. This extraction process improves relevance while managing complexity by focusing processing efforts only on pertinent data elements.
Solution Approach 2:
The patent implements local quality by tailoring the information presentation to the specific context of each scene. Instead of uniformly processing all program ancillary data, the system processes and presents information locally within each scene based on what is actually displayed and relevant to that particular moment in the program, improving relevance without requiring complex processing of the entire dataset uniformly.
Data Source
AI summary
A program ancillary data processing apparatus is provided which includes a program ancillary data extraction unit for extracting program ancillary data pertinent to commodities or services appearing in each scene, from picture program data, and a display control unit for displaying, on a display picture, the information relevant to the commodities or services appearing in each scene, and the sum total of the number of times of scene-based access events by the audience to a database supervising the detailed information relevant to the commodities or services, based on the preset layout information.
