Full-automatic recording and broadcasting system used for remote instruction

Abstract

The invention relates to a full-automatic recording and broadcasting system used for remote instruction. The full-automatic recording and broadcasting system comprises a video signal collecting module, a voice frequency signal collecting module, an automatic recoding and broadcasting editing module and a graphic workstation, wherein the video frequency signal collecting module and the voice frequency signal collecting module are both connected with the automatic recording and broadcasting editing module. Collected video frequency signals and voice frequency signals are transmitted to the automatic recording and broadcasting editing module, the automatic recording and broadcasting editing module is connected with the graphic workstation, after being edited into voice-video frequency files by the automatic recording and broadcasting editing module, the video frequency signals and the voice frequency signals are transmitted to the graphic workstation, and the graphic workstation conducts compressed encoding to the voice-video frequency files to produce streaming media files. Compared with the prior art, the full-automatic recording and broadcasting system used for the remote instruction can record and edit live teaching conditions in a real-time mode, no operation control by a specially-assigned person is needed during the whole teaching recording process, the graphic workstation can conduct the compressed encoding to the voice-video frequency files to produce the streaming media files and the streaming media files are uploaded onto the internet to be transmitted in a live mode.
