Synchronized Text Display with Audio Playback Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Music enthusiasts face difficulties in synchronizing song lyrics with audio playback, requiring manual scrolling through static lyrics pages to find the exact line being sung, which is inefficient and lacks real-time synchronization.
Innovation Solution
A system and method that receive an audio signal, determine the audio track identity and position, and display synchronized text, automatically scrolling it in pace with the audio, with a current text indicator visually synchronized to the audio playback, allowing users to interactively control playback positions and update synchronization dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a static lyrics page is displayed manually scrolled through, then the user can view song lyrics, but the user cannot real-time synchronize lyrics with audio playback
Solution Approach 1:
The patent applies dynamics by transforming the static lyrics display into a dynamic system where lyrics automatically scroll and synchronize with audio playback. The lyrics display adapts its scrolling speed and position in real-time based on the audio playback state, enabling precise synchronization without manual user intervention.
Solution Approach 2:
The system performs self-service by automatically tracking audio playback position and updating the lyrics display accordingly. The synchronization mechanism operates autonomously, continuously adjusting the visible lyrics portion based on the audio stream without requiring active user control or manual scrolling.
2Productivity
If text is automatically scrolled in pace with audio, then real-time synchronization is achieved, but the system complexity increases
Solution Approach 1:
The patent introduces an intermediary synchronization layer that coordinates between audio playback and text display. This mediator component processes audio timing information and translates it into appropriate text scrolling behavior, simplifying the overall system architecture while achieving precise synchronization.
Solution Approach 2:
The system performs preliminary actions by pre-loading and buffering lyrics data before it is needed during playback. The synchronization mechanism anticipates upcoming lyrics based on audio timing and prepares the display in advance, improving synchronization efficiency without adding significant complexity.
3Ease of operation
If a current text indicator is visually synchronized to audio, then user identification of current lyrics is enhanced, but the display complexity increases
Solution Approach 1:
The patent employs color changes to enhance the visibility and identification of current lyrics. The current text indicator uses distinct color coding that changes or updates in synchronization with audio playback, making it easy for users to identify the current lyrics at any moment without adding complex display mechanisms.

AI summary
Technologies described relate to coordination between audio and tracking of the corresponding text in an audio recognition mode and an audio playback mode. Optionally, audio recognition includes receiving a signal corresponding to an audio track; determining an identity of the audio track and a current audio position within the audio track; displaying on a display a portion of a text that is linked and synchronized to the audio track identified and automatically scrolling the portion of the text displayed in pace with the audio track playing; and displaying a current text indicator that emphasizes current text, wherein the current text indicator is visually synchronized on the display to current audio playing from the audio track. Optionally include redetermining the current audio position in the audio track from the signal received and updating synchronization of the current text indicator with the current audio playing.
