Recording system and method used for teaching and meeting place

Abstract

The invention relates to a recording system and a method which are used in teaching and venues. The system consists of a host which is connected with a video record device and an audio record device. The host consists of an audio input interface, a video input interface, a computer interface, a major control unit, a storage cell, a video source switching module and a slide processing module; wherein, the video source switching module matches the major control unit for switching the video source, the slide processing module is used for receiving and demonstrating slide signals in the computer, the major control unit processes the received audio signals, video signals and slide signals to produce multimedia files which consist of video contents and slide contents corresponding to time. The host can be externally connected with a demonstrating computer. A remote control can be used for controlling the recording process and the switching of the video source when in use. The recording process requires no coordination of a plurality of people, and editing processing is not required after the recording. A time corresponding relationship is established between the recorded video and the slide pictures.
