Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] see figure 1 , the present invention provides a kind of technical scheme: a kind of synchronous method in piano video teaching, the specific steps of this synchronous method are as follows:

[0023] S1: The sending end independently samples, frames and packs the audio and video information in piano teaching, and then puts them in their respective buffer queues for sending;

[0024] S2: Create a demultiplexing thread, an audio decoding thread, a video d...

Abstract

The invention discloses a synchronization method and system in piano video teaching in the technical field of education and teaching. The system comprises an audio sampling module, a video sampling module, an audio encoding and packaging module, a video encoding and packaging module, a data sending module, an audio unpacking and decoding module, a video unpacking and decoding module and a synchronous playing module. By adoption of the synchronization method and system disclosed by the invention, the synchronous output of audio and video is effectively achieved, a large amount of video encodingdata and audio image data do not need to be buffered, thereby greatly reducing the use of system resources, and the synchronization method and system are suitable for embedded system platforms and are high in operation efficiency and relatively low in complexity of function implementation.

Description

technical field [0001] The invention discloses a synchronization method and system in piano video teaching, specifically in the technical field of education and teaching. Background technique [0002] Piano is one of the current means of entertainment. With the development of society, the proportion of children taking piano lessons is getting higher and higher. With the popularization of the Internet, distance learning has become a common way in today's information-advanced world. teaching methods. The online teaching classroom focuses on the simultaneous recording of video and audio signals at the teaching site, and real-time live broadcast on the Internet to meet the needs of piano courses. However, in the existing network piano teaching, there is a problem that the video and audio signals received by the client are not synchronized, and students cannot clearly learn the content of piano teaching, which affects the quality of video teaching. Therefore, we put forward a s...
