TV Audio DNA Extraction for Music Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for searching music-related information during TV broadcasts face challenges due to the need for separate music recording processes and low recognition rates caused by environmental noise and sound volume differences, especially when music lacks clear words or is not audible.
Innovation Solution
A system and method that extract an audio signal from the TV's broadcasting signal, identify music using audio DNA, and provide related information by comparing the extracted audio DNA with a database, utilizing a music search server to match the audio DNA with pre-stored music information and broadcast details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If music search is performed using mobile terminal microphone to capture broadcast music, then music information can be searched, but recognition rate is low due to environmental noise and sound volume differences
Solution Approach 1:
The patent introduces an audio extractor as an intermediary component that captures audio signals directly from the broadcast signal source rather than through environmental microphones. This intermediary approach isolates the music signal from environmental noise, enabling accurate recognition by comparing the extracted audio DNA with the database without contamination from surrounding sounds or volume variations.
2Loss of information
If separate music recording process is used to capture broadcast music, then music data can be obtained for search, but the process becomes complex and time-consuming
Solution Approach 1:
The patent merges the music recording function with the broadcast signal processing function by integrating the audio extractor into the existing broadcast reception system. Instead of using a separate recording device, the system extracts audio signals directly from the broadcast signal stream, combining multiple functions into one unified process that reduces complexity and eliminates the need for separate recording equipment.
Solution Approach 2:
The patent performs preliminary extraction of audio signals from the broadcast signal before the music search process begins. By pre-extracting the audio DNA from the incoming broadcast signal and preparing it for comparison, the system eliminates the need for real-time recording during the search process, thereby simplifying the overall workflow and reducing the time required for music information retrieval.
3Productivity
If audio signal is extracted directly from TV broadcast signal for music identification, then recognition efficiency is improved, but requires integration with broadcast signal processing
Solution Approach 1:
The patent designs the audio extractor with multi-functionality to handle both broadcast signal processing and music identification tasks. The same component that processes broadcast signals for display also extracts audio DNA for music recognition, eliminating the need for separate dedicated hardware and reducing overall system complexity while maintaining high identification efficiency.
Data Source
AI summary
Disclosed herein is an apparatus and method for providing music related information by searching audio DNA information related to music output through, for example, a TV. The method including: receiving an audio DNA and broadcasting information of broadcasted music; identifying, using the music search server, the broadcasted music by determining whether the received broadcasting information matches music information and broadcast time of one of a plurality of broadcasting programs or advertisements, and comparing, when the determining fails to match the broadcasted music, the received audio DNA with audio DNA of the music pieces to identify the broadcasted music; searching detailed information on music identified by the audio DNA searcher; and transmitting the detailed information search result.
