Lyrics Extraction and MIDI Sync for External Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical apparatuses require expensive video-out devices to display lyrics, and there is a need to synchronize lyrics display with music data reproduction without relying on these costly devices.
Innovation Solution
An electronic musical apparatus that extracts lyrics data from music data, transmits it to an external device, and provides synchronization information to control the display, allowing lyrics to be displayed on an external device without the need for an expensive video-out device, using MIDI standards for data transmission and synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video-out device is used to display lyrics, then lyrics can be displayed on external apparatus, but the apparatus becomes expensive
Solution Approach 1:
The patent extracts only the essential lyrics data and synchronization information from the music data, separating them from the full audio stream. This allows the external display device to receive and display lyrics without requiring the expensive video-out device, as only minimal data transmission is needed between the music player and display apparatus
Solution Approach 2:
The patent introduces a data transmission protocol that acts as an intermediary between the music player and display device. This protocol enables communication through standard audio interfaces without requiring specialized video output hardware, thus reducing cost while maintaining lyrics display functionality
2Adaptability or versatility
If lyrics data is transmitted to external device, then lyrics can be displayed on separated displaying device, but synchronization control becomes complex
Solution Approach 1:
The patent embeds synchronization information directly into the transmitted data stream before playback begins. This preliminary preparation ensures that the external display device receives timing cues in advance, eliminating the need for complex real-time synchronization adjustments during music playback
Solution Approach 2:
The patent implements a feedback mechanism where the music player continuously monitors playback position and adjusts synchronization information accordingly. This feedback loop ensures precise synchronization between music playback and lyrics display without requiring complex manual coordination between the two devices
Data Source
AI summary
An electronic music apparatus comprises an extractor that extracts lyrics data from music data for reproduction of music and comprising the lyrics data representing lyrics of the music, a transmitter that transmits the extracted lyrics data to an external device, a reproducer that reproduces the music data, and a outputting device that outputs synchronization information for controlling display of the lyrics by the external device based on the lyrics data to the external device during reproduction of the music data in accordance with a progress of the reproduction of the music data.
