Channel Matching Table Generation for Broadcasting Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for matching broadcasting channels between metadata and actual broadcasting signals suffer from low accuracy due to data omission and errors, leading to a deterioration in service quality.
Innovation Solution
An electronic apparatus and control method that compares channel identifiers, names, and broadcasting program information to enhance the matching success rate between metadata and broadcasting signals, using a processor to generate a channel matching table based on similarities in program titles, broadcasting time information, and channel identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If channel matching is performed using only channel identifiers from metadata, then the matching process is simple, but the matching accuracy deteriorates due to data omission and errors
Solution Approach 1:
The patent merges multiple matching criteria (channel identifiers, channel names, and broadcasting program information including program titles and broadcasting times) into a comprehensive matching process. This combination allows the system to cross-validate information across different data sources, thereby improving matching accuracy while maintaining manageable process complexity through systematic comparison procedures
2Reliability
If multiple matching criteria are used to improve matching accuracy, then the matching success rate improves, but the processing complexity increases
Solution Approach 1:
The patent segments the matching process into distinct stages: first comparing channel identifiers, then channel names, and finally broadcasting program information such as program titles and broadcasting times. This segmentation allows each comparison step to be handled independently and systematically, improving overall matching reliability while keeping the complexity of each individual step manageable
3Reliability
If comprehensive channel matching is performed using program titles and broadcasting time information, then the service quality improves, but the processing time increases
Solution Approach 1:
The patent performs preliminary comparisons using channel identifiers and channel names before proceeding to more time-consuming comparisons of broadcasting program information. This preliminary action filters out obvious matches early in the process, reducing the number of cases that require extensive processing of program titles and broadcasting times, thereby improving service quality while minimizing additional processing time

AI summary
An electronic apparatus includes a communication interface, a broadcasting signal receiver to receive a broadcasting signal, and a processor configured to receive first broadcasting schedule information including channel names and broadcasting program information for a plurality of first broadcasting channels from a server through the communication interface, obtain second broadcasting schedule information including channel names and broadcasting program information for a plurality of second broadcasting channels from the broadcasting signal, match the plurality of first broadcasting channels with the plurality of second broadcasting channels, and generate a channel matching table by matching the plurality of first broadcasting channels with the plurality of second broadcasting channels by comparing at least one of the channel names or the broadcasting program information included in the first broadcasting schedule information with at least one of the channel names or the broadcasting program information included in the second broadcasting schedule information.
