Cloud recording and broadcasting system

Abstract

The invention provides a cloud recording and playing system which comprises an audio and video terminal used for receiving first audio information, first video information and courseware information,performing first keyword extraction on the first audio information, recording time position information of a first keyword, labeling the first keyword in first video data, and generating first targetinformation; a first network device; arecording and playing platform which is used for receiving the first target information in real time, decoding the first target information, generating first audio information, marking first video information and courseware information of a first keyword, and then synthesizing the first audio information, the first video information marked with the first keyword and the courseware information to generate first target information flow; When a live broadcast request message sent by the user terminal is received, the first target information flow is sent to the user terminal; Or, when the on-demand request message sent by the user terminal is received, the first target information flow is sent to the user terminal. Therefore, the data processing burden ofthe recording and broadcasting platform is reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a cloud recording and broadcasting system. Background technique [0002] The advancement of science and technology and the development of social civilization are constantly creating a large amount of knowledge, which puts forward higher requirements for the learning ability of modern people. If a person wants to gain a foothold in society and achieve better development, he must learn enough technology cultural knowledge. [0003] In recent years, more and more technologies such as computers, networks and multimedia have been applied to the field of education, which has promoted the gradual popularization of education informatization. Educational informatization is the use of computer multimedia network information technology to promote the overall reform of teaching, so that it can adapt to the new requirements of the information society for the development of education,...

Problems solved by technology

[0004] The traditional teaching mode is that one teacher is responsible for the teaching of one class, and at the same time, one teacher cannot simultaneously guide the teaching for students in other classes

Moreover, it also limits the sharing of high-quality teacher resources, making it impossible for more students to enjoy the education of high-quality teachers.

[0005] In recent years, with the rapid development of digital learning technology, universities, governments and enterprises are vigorously promoting the online learning education mode, which provides a better online learning platform for the public. However, with the continuous development of online learning , the problems that appear in it are becoming more and more obvious, such as unclear network video, out-of-sync voice and picture, large amount of data processing, etc.
