Cloud-computing-technology-based recording and broadcasting system and method

Abstract

The invention provides a cloud-computing-technology-based recording and broadcasting system. The system comprises cloud recording and broadcasting all-in-one machines and a cloud recording and broadcasting management center, wherein the cloud recording and broadcasting all-in-one machines are distributed within recording and broadcasting rooms, and used for acquiring and outputting an audio and video signal and a VGA (video graphics array) signal, generating an integrated multimedia courseware, and transmitting the acquired audio and video signal to the cloud recording and broadcasting management center through a network, and asking for the cloud recording and broadcasting management center to monitor and mange the acquired audio video signal; and the cloud recording and broadcasting management center comprises a cloud recording and broadcasting management server and a streaming media server, wherein the cloud recording and broadcasting management server is used for monitoring and managing the recoding process of the cloud recording and broadcasting all-in-one machines of the recording and broadcasting rooms, and the streaming media server is used for providing a recording and broadcasting resource to a far-end user. According to the recording and broadcasting system provided by the invention, the recoding and the managing can be separated from each other, and the remote management can be effectively carried out on the recording and broadcasting process. The invention further provides a cloud recording and broadcasting method correspondingly.

Description

technical field [0001] The invention relates to the technical field of recording and broadcasting, in particular to a recording and broadcasting system and method based on cloud computing technology. Background technique [0002] In the past ten years, with the rapid development of digital learning technology, universities, governments and enterprises have vigorously promoted the online learning education model. The online learning and education model 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, for example, the online video is not clear, and the voice and picture are out of sync, etc. . Throughout the development process of the recording and broadcasting system, it is divided into the following three stages: the first stage, the single-machine version of the recording and broadcasting system, mainly collects and records the teacher's...
