AI Technical Summary

Technical Problem

The existing separate architecture of karaoke devices and projection devices makes it difficult to synchronize audio and video, resulting in cumbersome operation and a poor user experience. In particular, under network fluctuations or high system load, audio and video misalignment, latency and stuttering are severe, and one-click scene switching and automatic parameter adaptation cannot be achieved.

Method used

The system receives user commands through a unified control interface, generates coordinated scheduling commands with synchronization identifiers, drives audio and video processing threads to execute in parallel, completes timing alignment based on synchronization identifiers, integrates a graphical user interface for centralized control, and dynamically adjusts resource allocation strategies to ensure audio and video synchronization.

Benefits of technology

It achieves real-time and precise audio-visual collaboration, improves ease of operation and user experience, eliminates the problems of audio-visual misalignment and disconnected interaction, and meets the convenience needs of home users for integrated intelligent control.

Abstract

The application discloses a karaoke projection all-in-one machine control method, comprising: receiving user instructions acting on a unified control interface; in response to the user instructions, generating and issuing a cooperative scheduling instruction containing a synchronization identifier; according to the cooperative scheduling instruction, executing an audio processing thread and a video processing thread in parallel; in the audio processing thread, generating a first output signal by real-time processing of an audio signal according to the synchronization identifier; in the video processing thread, generating a second output signal by real-time processing of a video signal according to the synchronization identifier; timing alignment of the first output signal and the second output signal; controlling an audio playing unit to play the aligned first output signal, and controlling a projection display unit to project the aligned second output signal. The application solves the sound and picture dislocation and interaction fragmentation problem caused by communication delay, protocol difference and resource conflict under the separation type architecture, and realizes the convenience improvement of audio and video real-time accurate cooperation and one-key intelligent control.
