Synchronizing Electronic Interactive Devices with Real-Time Music
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic interactive devices struggle to synchronize with real-time music segments in noisy environments, such as concerts, due to difficulties in associating them with standard music segments, which hinders their ability to perform pre-arranged actions at predetermined points.
Innovation Solution
The method involves identifying peak and valley points in soundtracks by calculating energy and comparing them to determine similarity, using techniques like Fast Fourier Transform (FFT) and signal-to-noise ratio (SNR), and potentially employing watermarks to authenticate and synchronize the soundtracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic interactive device attempts to synchronize with real-time music segments in noisy environments, then the ability to perform pre-arranged actions at predetermined points is improved, but the accuracy of associating real-time segments with standard segments deteriorates due to surrounding noises
Solution Approach 1:
The patent introduces watermarks as intermediary signals embedded in the music segments. These watermarks serve as reliable reference markers that can be detected even in noisy environments, enabling the electronic interactive device to accurately associate real-time segments with standard segments without being adversely affected by surrounding noises.
Solution Approach 2:
The system implements feedback mechanisms where the detected peak points and valley points from watermarks are continuously monitored and used to adjust the synchronization process. This feedback loop allows the device to maintain accurate timing and association despite environmental noise interference.
2Measurement precision
If the electronic interactive device uses energy-based peak and valley point detection to identify synchronization points, then the ability to identify trigger points is improved, but the complexity of the detection algorithm increases
Solution Approach 1:
The patent embeds watermark signals that contain copied or replicated peak and valley point patterns into the music segments. These watermarked copies serve as predetermined reference points that can be easily detected and matched, simplifying the synchronization process while maintaining high precision in identifying trigger points.
3Speed
If the electronic interactive device processes music segments in real-time to maintain synchronization, then the responsiveness to music events is improved, but the computational energy consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-embedding watermarks with known peak and valley point patterns into the standard music segments before playback. This allows the electronic interactive device to simply detect and match these pre-defined patterns in real-time without performing complex analysis, thereby maintaining fast synchronization response while minimizing computational energy consumption.

AI summary
A method for synchronizing an electronic interactive device on basis of a first sound track is provided. The method may include identifying a first peak point and a valley point of the first sound track by calculating a first energy of the first peak point and a first energy of the valley point of the first peak point and comparing the first energy of the first peak point with first energy of neighboring points of the first peak point. The method may also include identifying a first peak point of a second soundtrack, and determining a similarity between the first soundtrack and a second sound track on basis of the first peak point of the first soundtrack and the first peak point of the second sound track.
