Display Apparatus Background Music Identification via Audio Parameter Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in retrieving and downloading background music from TV programs or movies as existing services interrupt the viewing experience and require manual identification and replaying content to access music information.
Innovation Solution
A display apparatus and method that extracts audio parameters of background music, transmits them to an external server for identification, and displays a music album list on an external device without interrupting the user's viewing experience, allowing seamless access to background music information and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a service automatically identifies background music in real-time, then background music identification accuracy is improved, but user viewing experience is interrupted
Solution Approach 1:
The system extracts and stores audio parameters of background music in advance during content playback without interrupting the user. When the user requests background music information, the pre-extracted parameters are quickly matched against a database to identify the music, eliminating the need for real-time interruption while maintaining identification accuracy.
2Loss of information
If manual identification and replaying of content is required, then background music information retrieval is achieved, but time consumption increases
Solution Approach 1:
Audio parameters are extracted and stored in advance during content playback. When identification is needed, the system directly uses these pre-extracted parameters for quick database matching, eliminating the time-consuming process of replaying content to identify background music.
Solution Approach 2:
Instead of replaying the original content to identify background music, the system creates and uses a separate copy of audio parameters that were extracted beforehand. This allows rapid identification without needing to re-play the video content, significantly reducing time consumption.
3Ease of operation
If background music information is displayed on the display apparatus, then user access to music information is improved, but content viewing is interrupted
Solution Approach 1:
The system uses an external apparatus as an intermediary to display background music information. The display apparatus sends a request to identify background music, receives the identification result, and then transmits it to the external apparatus for display. This allows users to access music information on their personal devices without the display apparatus interrupting the content viewing experience.
Data Source
AI summary
A background music providing method includes: based on a user command for executing a content recognition mode being received, obtaining a data corresponding to the content, reproduced on the display apparatus, in the content recognition mode; transmitting the obtained data to an external source; obtaining information corresponding to the content based on the data from the external source; and displaying a result UI corresponding to the obtained information on the display apparatus.
