Image Display Device EPG Metadata Inconsistency Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image display devices face inaccuracies in providing broadcast program information due to inconsistencies between electronic program guide (EPG) information and metadata, leading to incorrect user information.
Innovation Solution
An image display device equipped with a communication interface, memory, and processor that obtains EPG information and metadata, compares them for inconsistencies, regenerates accurate broadcast program information, and displays it, while also generating error data to update metadata providers for corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If broadcast program information is provided using both EPG information and metadata, then the information can be more comprehensive, but inconsistencies between the two data sources lead to inaccuracies in the provided information
Solution Approach 1:
The system implements a feedback mechanism by comparing EPG information and metadata, detecting inconsistencies, and regenerating accurate broadcast program information based on the comparison results. This closed-loop approach ensures that information accuracy is continuously maintained by identifying and correcting discrepancies between the two data sources.
Solution Approach 2:
The system performs preliminary comparison and validation of EPG information and metadata before generating the final broadcast program information. By pre-checking for inconsistencies and resolving conflicts in advance, the system ensures that only accurate and consistent information is provided to users, preventing information errors from propagating.
2Reliability
If the system compares EPG information with metadata to ensure accuracy, then the reliability of broadcast program information improves, but the processing time and system complexity increase
Solution Approach 1:
The system divides the information processing into distinct segments: obtaining EPG information, obtaining metadata, comparing the two data sources, and regenerating accurate broadcast program information. This segmentation allows each processing step to be independently optimized and managed, reducing overall system complexity while maintaining high reliability through systematic validation.
Data Source
AI summary
Provided are an image display device and an operation method thereof. An image display device for providing broadcast program information including a communication interface, a memory storing one or more instructions, and a processor configured to execute the one or more instructions stored in the memory. The one or more instructions may cause the processor to obtain electronic program guide (EPG) information about a broadcast program through the communication interface, obtain metadata about the broadcast program, compare the EPG information with the metadata, and based on identifying that the broadcast program indicated by the EPG information and the broadcast program indicated by the metadata are inconsistent (do not match), regenerate the broadcast program information to be provided to a user, based on the EPG information, and cause a display to display the regenerated broadcast program information on the display.
