Ultra-low delay synchronization method for network teaching of group musical instrument

Abstract

The invention provides an ultra-low delay synchronization method for network teaching of a group musical instrument, and the method comprises the steps: enabling a teacher end and at least one studentend to be connected with wifi, enabling the student end to record the current time t1, and transmitting a time instruction t2 for requesting the teacher end to the teacher end; after receiving the instruction, enabling the teacher end to reply to the student end and carry the current time t2 of the teacher end; after receiving the reply from the teacher end, enabling the student end to record thecurrent time t3 of the student end when receiving the instruction; and enabling the student end to calculate the unidirectional network [delay]t=(t3-t1) / 2 of the instruction, and further calculate the system clock time difference T=t3-t2-t between the student end and the teacher end. The ultra-low delay synchronization method for network teaching of the group musical instrument solves the problemthat clocks of the teacher end and student ends are not synchronous, and has the characteristics that the upper limit of the number of the student ends can be greatly increased, the synchronization delay is small, and synchronization among different sound sources is supported.

Description

technical field [0001] The invention belongs to the field of network music education, and in particular relates to an ultra-low delay synchronization method for network teaching of musical instruments in a group. Background technique [0002] With the development of Internet technology, more and more Internet technologies have been applied to the field of music education. The group teaching of instrumental music has gradually begun to use Internet technology and software network teaching, such as common electric piano classrooms, electric drum classrooms, etc. . [0003] Under the existing technical conditions, because the teacher needs the musical instruments to sound at the same time when teaching the instrumental music group class, the traditional way is to rely on the teacher's starting password, and the students play according to the password, and the problem of irregular starting at the same time often occurs. Some existing teaching software starts to replace the teac...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims to propose an ultra-low-latency synchronization method for group musical instrument network teaching, which adopts the wifi wireless connection method, no longer requires physical wiring of network cables, and solves the messy wiring of the teaching site and the poor experience of the teaching environment At the same time, the clock synchronization measurement method is adopted to solve the problem of clock asynchrony between the teacher's end and the student's end. It has the characteristics of a large increase in the number of student ends, a small synchronization delay, and support for synchronization between different audio sources.
